CDER Group: Are They Legitimate and What Can They Do?

Yes. CDER Group is a real enforcement company, registered at Companies House and instructed by local authorities to recover unpaid council tax, parking penalties and other sums owed to councils. A letter from them is not a scam, and treating it as one is the most expensive mistake available, because enforcement fees rise at each stage while you ignore it.

That said, "real" and "correct" are different things. The company can be genuine and the debt still be wrong, the balance still be disputed, or the fees still be overcharged. This page covers both: how to satisfy yourself the letter is authentic, and what to do about it once you have.

How to check CDER Group is genuine, yourself

Do not take our word for it, or theirs. Three independent checks take about five minutes.

Check the company at Companies House. CDER Group Limited is registered under company number 04118149, with its registered office at 3rd Floor, 10 Lloyd's Avenue, London, EC3N 3AJ. Search the number rather than the name at find-and-update.company-information.service.gov.uk.

Be aware that more than one CDER company exists on the register, including CDER Group UK Limited (09903291). That is not a red flag in itself, since groups commonly hold several companies, but it does mean the company number on your letter identifies the sender far more reliably than the brand name.

Check the individual agent. Enforcement agents must be certificated by a County Court judge. The certificated enforcement agent register is public, and an agent attending your home should be able to give you their name and certificate details on request.

Check with the council. If the letter says it relates to council tax or a penalty owed to a named authority, telephone that authority using a number from its own website, and ask whether it has instructed CDER on your account. This is the single most conclusive check, and it costs one phone call.

If any of those three do not line up, stop and do not pay anything until they do.

Do you have to pay CDER Group?

Where the council tax or penalty really is yours and a valid order or warrant sits behind it, yes: the sum is owed and CDER may lawfully collect it.

Owing the money still leaves you room to question everything around it. Nothing stops you from:

• requiring CDER to identify the debt and the order or warrant it acts under
• demanding an itemised statement showing how each fee arose
• taking a challenge to the underlying sum to the council, which controls the account
• offering instalments matched to what you can actually sustain
• insisting that any vulnerability shapes how the case is handled

The one strategy with a guaranteed price tag is doing nothing, because the statutory fee ladder climbs while you wait: £79 if resolved in the notice period, £326 or more after an agent calls.

Why has CDER Group contacted you?

CDER describes its client base as more than 200 local authorities together with Transport for London, National Highways and HM Courts and Tribunals Service (cdergroup.co.uk, checked 22 Aug 2026), so its letters almost always trace back to a public body. That figure and client list are CDER's own description; the HMCTS relationship specifically is independently confirmed below. Behind yours there is normally a chain like this:

1. a council tax instalment or a penalty charge went unpaid
2. reminders and a final notice followed and lapsed
3. the authority converted the debt into something enforceable, a liability order for council tax or, for a penalty, a warrant of control issued through the Traffic Enforcement Centre
4. only then was the account placed with CDER.

Missing every earlier step is common and proves nothing either way. Courts grant liability orders in bulk without the taxpayer present, and paperwork sent to a previous address never arrives. Verify before you dismiss.

What debts do CDER enforce?

The firm's own list of services runs across council tax, parking, road traffic and road user charges, commercial rent arrears, business rates and criminal court fines. In practice the letters people bring to us are dominated by penalty charge enforcement, bus lane and moving traffic cases included, with council tax liability orders close behind and business rates a distance back.

Consumer credit is conspicuously absent from that list. A CDER demand about a credit card, catalogue or personal loan deserves real scepticism, since such debts rarely arrive at Schedule 12 enforcement, and never without county court proceedings you would know about.

Which councils use CDER Group?

Councils are required to tell residents who may attend on their behalf, and most publish a list of the enforcement agents they instruct on their own recovery pages.

If you want to confirm that CDER act for your council, that published list is the authoritative source, and it is more reliable than any third party summary including this one.

Are CDER Group bailiffs or debt collectors?

Enforcement agents. On a CDER letter that word choice is doing real legal work, not marketing.

A debt collector writes and telephones. Nothing in its toolkit touches your property or your front door, because until a creditor has sued and won there is no court authority behind the demand at all.

CDER's caseload starts from the opposite position. By the time a file reaches its agents, a liability order or warrant usually already exists, and Schedule 12 of the Tribunals, Courts and Enforcement Act 2007 then governs what happens: goods can be taken into control, the statutory fee scale applies, and reasonable force is available only in the narrow situations the Schedule itself spells out.

Our guide to bailiffs and debt collectors explains how to tell which you are dealing with from the document itself.

Are CDER Group FCA regulated?

No, and that is normal for an enforcement firm rather than a concern.

Taking control of goods is not a regulated activity under the Financial Conduct Authority, so enforcement companies generally do not appear on the FCA register. Their conduct is governed instead by Schedule 12, the Taking Control of Goods Regulations, the certification of individual agents, and the Enforcement Conduct Board.

A debt collection agency would appear on the FCA register. An enforcement firm ordinarily would not. Absence is not evidence of anything wrong, and anyone telling you otherwise has misunderstood which rulebook applies.

Which CDER stage are you at, and what has it cost so far?

Enforcement fees come from a statutory scale, not from CDER's price list. The same three figures bind every certificated firm in England and Wales, and inventing a fourth is not an option open to any of them.

The scale above governs instructions received under the rules in force from 1 May 2026; a case CDER took on earlier can still sit on the previous figures, so always establish the instruction date before auditing a balance.

What if CDER hold several of your debts?

Multiple penalty charges landing with one firm is a routine event in traffic enforcement, which makes this the single most profitable place to audit a CDER balance.

Regulation 11 of the Fees Regulations draws the line. When one firm holds several enforcement powers against you that can reasonably be exercised together, each debt properly carries its own £79 compliance fee, but the visit-stage £247 and the sale-stage £116 are chargeable a single time across the lot.

Run the arithmetic on three warrants handled together: £237 in compliance fees plus one £247 enforcement fee makes £484. A balance showing £326 three times over, £978, has been built per debt rather than per visit, and roughly £494 of it should not be there.

Overcharges of that kind are recoverable. Put the challenge in writing and require a fee-by-fee schedule stating the date and the triggering event behind every charge.

What does a CDER Notice of Enforcement mean?

A Notice of Enforcement is the statutory warning shot: until one has been given, taking control of goods cannot lawfully start.

Where CDER received the instruction under the rules in force from 1 May 2026, the notice has to allow a minimum of 14 clear days before goods can be taken into control, double the seven days the older rules gave. Counting is strict: neither the day the notice is given nor the final day counts towards the 14.

The same reform lets a recognised debt adviser apply to stretch that period to at least 28 clear days unless the debt is a non-eligible business debt, subject to the conditions and deadline in the regulations.

Nothing later in the process is this cheap. Settle or arrange within the notice window and the enforcement costs stop at £79.

Can CDER Group force entry into your home?

Enforcing council tax or a parking or traffic penalty, no: a first visit to a home carries no forced entry power.

The statute allows entry only where it happens peaceably. An open door, an unlocked one, an invitation: those qualify. Breaking locks, climbing through windows and shouldering past the occupier do not.

Nor does the law oblige you to answer a knock. Staying behind a closed door costs you nothing legally, and talking through it while you work out which debt this is remains a perfectly sensible tactic.

Situations where force can enter the picture exist, but they are tightly drawn and mostly beyond the council tax and penalty work CDER typically handles at a private address: commercial premises are treated more robustly than homes; a broken controlled goods agreement can generate a forcible re-entry power; and criminal fines plus certain HMRC debts follow their own, harsher regime.

Our guide to when bailiffs can force entry maps each situation to the Schedule 12 paragraph behind it.

What if you do not answer the door?

In the short term, very little. Denied peaceable entry, the agent has to withdraw.

Three things stay open to them all the same: a car parked on the road or drive can be taken into control without any entry, the £247 enforcement fee attaches once its statutory trigger is met, and further visits will follow. Treat a closed door as breathing space to sort the case out, not as a resolution.

What can CDER take, and can they take your car?

Only goods of the debtor can be taken into control. Being in the same house as the debt does not make your partner's laptop or your flatmate's television available, although in practice you should expect to prove whose things they are.

The exemptions in regulation 4 then carve out the essentials of a functioning home. Basic clothing and bedding stay. So does the equipment a household reasonably needs day to day: the fridge, the cooker, the washing machine, beds, a table to eat at. Anything reasonably required for medical care, or for looking after a child, an older person or someone disabled, is off limits, as are domestic pets and assistance dogs, and a vehicle displaying a valid disabled person's badge that is used to carry a disabled person. Work tools have a ceiling rather than blanket protection: equipment necessary for your own work or study is exempt up to £1,350 in total.

Vehicles

For a firm whose instructions are weighted towards traffic penalties, the car on the road outside is usually the first asset an agent looks for, and no entry to the house is needed to clamp or remove it.

Whether it can lawfully be taken is nearly always an ownership question. Leased vehicles, which includes every Motability Scheme car, are not the debtor's goods. Finance agreements complicate hire purchase and PCP vehicles, where title may still sit with the lender. A car registered to and paid for by your partner or a relative belongs to them, not to the debt. And a van or car genuinely necessary for your own work can come within the £1,350 tools exemption.

Where one of these fits your situation, get the paperwork to CDER the same day and ask in writing for the vehicle to be left alone while ownership is verified, rather than waiting to argue at auction stage. See what bailiffs can take and can bailiffs take my car.

Can you arrange a payment plan with CDER?

In most cases yes, and where the debt is really yours an instalment deal normally beats every alternative.

The usual vehicle for one is a controlled goods agreement: your possessions are listed, valued and left in place, on condition the payments arrive. Read the schedule of goods line by line before you sign. Items that are not yours, items regulation 4 exempts, optimistic valuations and fee errors all belong on the table at this point, not after a default.

Understand what your signature changes. Break the agreement later and the agent may acquire a re-entry power that simply did not exist beforehand. More households lose the protection of a closed door this way than any other.

What if you cannot afford to pay?

Put numbers in front of them early. A proposal built on a genuine income and expenditure statement carries weight that a plucked figure never will, and either is better than saying nothing.

National Debtline, StepChange and Citizens Advice will help you build that statement without charging you anything.

CDER's online portal, and what to check first

CDER runs a self-service portal at customer.cdergroup.co.uk, reached through the "Pay Now" and "Manage my account" links on the firm's own website, with a separate portal at hmcts-customer.cdergroup.co.uk for HMCTS cases. Logging in usually takes the CDER reference and the client reference printed on your notice, or an account registered to your email address, and the customer phone line is 0330 460 5295.

Two references means two chances to pay against the wrong case, so check what you type against the letter actually in front of you. Note also that money paid there goes to CDER, not to the council, so keep the receipt and the confirmation of which debt it settled.

A part payment through the portal does not by itself pause enforcement or stop the fees moving to the next stage. If the balance is not realistically payable, make the affordability case described above before paying anything, or get help first.

Challenging a CDER balance with the council

Aim the dispute at the council, with CDER copied in, not the other way round.

The division of power explains why: CDER holds an instruction to collect a stated sum. Correcting a council tax band error, applying a missed discount or cancelling a PCN all sit with the authority that raised the charge, and no amount of arguing with the agent changes an account the agent does not own.

From the council, request the account's billing history, the order or warrant details with date and amount, the property and period concerned, and a transaction list covering payments and added costs. Attach evidence for any single person discount, exemption or council tax reduction that never made it onto the account.

Simultaneously notify CDER in writing that the sum is under formal dispute with the council, which gives them a documented reason to pause.

What if the letter is for someone else, or an old address?

Respond quickly rather than binning it. A short letter enclosing something that shows current occupancy, your own council tax bill, tenancy or a recent utility statement, usually closes an address error down.

Resist the two tempting shortcuts. Paying a stranger's debt buys quiet at your expense, and silence invites a visit from an agent working on the assumption the named debtor still lives behind your door, at which point your possessions become the subject of an ownership argument.

Where the person named genuinely shares your home, the distinction is between their goods, which are exposed, and yours, which are not. Receipts and proof of purchase for anything valuable become worth keeping to hand.

CDER and vulnerability: what to tell them, and when

Raise it with the firm and with the instructing council at the first opportunity, in writing if at all possible. CDER's own site describes a specialist welfare team and partnerships with debt advice and mental health charities, which is the part of the organisation you want your case routed to.

No statute closes the category of vulnerability. Illness of body or mind, disability, a recent bereavement, pregnancy, old age, limited English or literacy, trauma and acute family crisis have all counted, often in combination. What matters is the effect: does your situation make enforcement materially harder for you to understand, respond to or bear?

Send supporting documents if you have them, and flag the circumstances immediately even if you do not.

Realistic outcomes range from the case moving to welfare handling, through extra time, adjusted contact methods and gentler payment terms, up to a hold on action or, under some councils' policies, the account going back to the council.

None of this writes the debt off. It disciplines how collection is carried out.

What if CDER is only one of several debts?

An enforcement letter is often the loudest debt rather than the most important one. Clearing CDER by skipping the rent, the gas bill or the food shop rarely leaves you better off overall.

Rank consequences, not volume. Anything that can end a tenancy, cut off supply or reach imprisonment outranks anything that only dents a credit file: a liability order belongs near the top of that ranking, a catalogue balance near the bottom.

Whole-situation advice beats letter-by-letter firefighting here, and the free services named above give exactly that.

CDER Group and council tax

Even with a caseload weighted towards penalties, council tax remains a major part of what CDER collects, and its legal shape is specific.

Everything hangs off a liability order, granted by the magistrates' court on the council's application. Until that order exists, no enforcement agent should be involved; once it does, taking control of goods becomes one of several routes open to the council, alongside attachment of earnings and deductions from certain benefits.

What the order does not do is licence a break-in. It starts the Schedule 12 procedure; peaceable entry rules still apply at your door.

Two points are widely misunderstood.

The six year rule. Regulation 34(3) of the Council Tax (Administration and Enforcement) Regulations 1992 sets a six year limit on when a liability order application may be instituted, counted from when the sum became due. Read it precisely: it constrains the application, not the order. One granted years ago has no built-in expiry, so "this is too old to enforce" usually fails as an argument on its own.

Paying the council instead of CDER. After referral, expect the council to send you back to the firm, and a payment made to the council does not by itself strip out fees that were properly added before it arrived. Recalling a case is within the council's gift, and evidenced vulnerability or a genuinely wrong account are the strongest grounds for asking, but you are requesting a discretion, not exercising a right.

Our guide to council tax bailiffs covers the whole journey, including when a council will take a case back.

CDER Group and parking or traffic penalties

A penalty charge notice reaches enforcement by a different route from council tax, and knowing which applies tells you which remedy you have.

An unpaid local authority penalty is registered as a debt at the Traffic Enforcement Centre, and the authority then obtains a warrant of control. That warrant, not a liability order, is the authority CDER act under.

Why does the route matter? Because the penalty track carries a court remedy that bypasses the enforcement agent completely. Never got the Notice to Owner? Appealed and heard nothing back? Not the vehicle's keeper when the contravention happened? Each of those grounds supports a declaration to the Traffic Enforcement Centre, made against a deadline, and succeeding there cancels the warrant CDER relies on rather than merely arguing about fees.

For an ordinary council parking penalty anywhere in England, or a council bus-lane or moving-traffic penalty outside London, the usual route is a witness statement on form TE9, with TE7 if it is late. For a TfL Congestion Charge, LEZ or ULEZ penalty, the statutory-declaration route uses PE3, with PE2 if late. London-borough or TfL bus-lane and moving-traffic cases sit under separate London legislation, so check the form enclosed with the order rather than assuming either route. Both routes are covered in our Traffic Enforcement Centre and PE3 and TE9 forms guides.

What happens if you miss a payment to CDER?

Few people ask this question in advance. Almost everyone who defaults wishes they had.

A missed instalment under a signed controlled goods agreement is a breach of that agreement, and a breach carries teeth an ordinary broken promise to pay does not.

The teeth are re-entry. Once the agreement is breached and the statutory conditions are satisfied, the agent may return for the listed goods, if necessary with reasonable force, a power the closed front door previously defeated. No single mistake converts a protected household into an enterable one more often than this.

So ring or write while the instalment is still ahead of you. A firm asked to vary terms usually engages; a firm watching payments stop tends to escalate.

Explain the change, quantify the new affordable figure, and if the original schedule was never going to hold, be candid about that as well.

After CDER remove goods: sale, proceeds and any surplus

A removal van leaving is not the end of the story. The law deliberately builds a gap between taking goods and selling them.

The Taking Control of Goods Regulations ordinarily require at least seven clear days between removal and sale, with limited exceptions, plus notice of when and where the sale will happen, and Schedule 12 obliges the agent to obtain the best price reasonably obtainable for what is sold.

That gap is your window. An exempt item, a third party's property, a payment CDER has not credited or a disputed balance should all be raised the day the goods go, in writing, with a request that the sale be suspended while it is resolved.

When a sale does complete, the money goes first to the debt and the recoverable enforcement costs. Anything left over is yours, and a written breakdown covering valuation, sale price, fees and allocation is a reasonable thing to insist on.

Auction prices for used household goods are poor, which is precisely why threatening removal is more common than carrying it out: after transport, storage and sale costs, ordinary furniture rarely repays the exercise.

If there is nothing worth taking, what does the council do next?

Some households simply hold nothing an auction would pay for: the essentials are exempt, the car is on finance or belongs to someone else, and the rest is low value. When an agent reaches that conclusion, the file usually goes back to the council marked accordingly.

The liability survives the return. From there the council's menu includes attachment of earnings, deductions from certain benefits, sometimes a charging order, and in rare, serious council tax cases an application for committal.

If the honest picture is no assets and no spare income, write that down with evidence and put it in front of the council yourself. A creditor shown a genuine inability to pay is far more open to a long, low arrangement than one left guessing.

Traffic penalties: the route most people miss

CDER's caseload is weighted towards parking and traffic penalties for local authorities and Transport for London rather than being purely council tax driven. That matters, because penalty charge enforcement has its own challenge route that has nothing to do with negotiating with the enforcement agent.

How a parking ticket becomes a warrant

1. A Penalty Charge Notice is issued.
2. Unpaid and unchallenged, a Notice to Owner follows.
3. A charge certificate increases the amount.
4. The debt is registered at the Traffic Enforcement Centre at the County Court Business Centre in Northampton.
5. An order for recovery is issued.
6. A warrant of control follows, and CDER is instructed.

By the time an enforcement agent contacts you, several documents have already been sent. If you never saw them, that is not merely bad luck, it is a ground of challenge.

The witness-statement and statutory-declaration routes

For an ordinary council parking penalty anywhere in England, or a council bus-lane or moving-traffic penalty outside London, the challenge is a witness statement on form TE9, sent to the Traffic Enforcement Centre. The form allows you to state that:

• you did not receive the Notice to Owner, Enforcement Notice or Penalty Charge Notice
• you made representations to the local authority within 28 days of service, *"but did not receive a rejection notice"*
• you appealed to the Parking or Traffic Adjudicator within 28 days of service of the rejection notice, *"but have had no response to my appeal"*
• you have already paid the penalty charge

If you are outside the time limit for that witness statement, form TE7 is the application for more time. For a TfL Congestion Charge, LEZ or ULEZ penalty, the separate statutory-declaration route uses PE3, with PE2 if it is late. London-borough or TfL bus-lane and moving-traffic cases sit under separate London legislation, so check the form enclosed with the order rather than assuming either route.

A successful declaration cancels the order for recovery and the warrant with it, which stops the enforcement agent entirely. It does not cancel the original penalty, which returns to the beginning of the process, but it removes the fees and the enforcement.

Two warnings. A TE9 witness statement is signed under a statement of truth, while a PE3 statutory declaration must be sworn before a Commissioner for Oaths, a Justice of the Peace or an officer of the court, and a fee may be payable. Both are formal legal documents. Do not select a ground that is not true.

Do not use the wrong form

Do not choose by form name alone. TE9 and TE7 cover ordinary council parking penalties, council bus-lane or moving-traffic penalties outside London, and also Dart Charge, Mersey Gateway and clean air zone charges. PE3 and PE2 cover TfL Congestion Charge, LEZ and ULEZ penalties. For a London-borough or TfL bus-lane or moving-traffic case, use the form enclosed with the order.

If you miss a payment to CDER

Two statutory consequences make pre-emptive contact with CDER worth the awkward phone call.

First, paragraph 19A of Schedule 12: breach a controlled goods agreement and forcible re-entry becomes legally available. Second, regulation 9(2) of the Taking Control of Goods Regulations 2013: default on a repayment arrangement made after the notice of enforcement and the 12-month clock for taking control of goods starts again from the day of the default, extending how long the case can stay live.

Already defaulted? Same-day contact, a fresh income and expenditure statement, and a written request to hold enforcement while it is reviewed are the three moves that limit the damage.

If CDER is one of several debts

Funding a CDER arrangement by starving the mortgage, the energy account or another priority debt relocates the crisis instead of resolving it, because those debts carry consequences a credit card never will.

When the underlying problem is the total rather than this account, structured options exist: our guides to debt solutions and the Breathing Space scheme set out what a free adviser can put in place.

CDER Group company details

CDER describes itself as a substantial London-based enforcement business working primarily for local authorities and Transport for London, and its work is weighted towards traffic and parking penalties rather than being purely council tax driven. That mix is the main practical difference between a CDER letter and one from a firm whose caseload is mostly council tax.

The firm also works directly for the courts. From 1 September 2020, HM Courts and Tribunals Service appointed CDER Group as an Approved Enforcement Agency covering the London, Midlands and South East lots in England, which is why a CDER agent can lawfully appear in connection with an unpaid criminal court fine as well as a council debt.

CDER is accredited by the Enforcement Conduct Board, which provides an escalation route beyond its internal complaints process.

How to complain about CDER Group

Sequence determines whether a complaint gets traction.

Stage one is internal. Send CDER a written complaint carrying the case reference, when it happened, which agent was involved, and above all which regulation or which factual error the complaint stands on. "Charged the enforcement fee twice contrary to regulation 11" moves; "your agent was unpleasant" drifts.

Stage two is the instructing council, the step most complainants never take despite it carrying the most leverage. The client can pull the case back or fix the account; the contractor cannot.

Stage three is external oversight. CDER holds Enforcement Conduct Board accreditation, so the ECB can look at conduct once the internal process is exhausted, CIVEA operates as the industry body, and a challenge to an individual agent's certificate goes through the issuing court.

A genuinely legal question, an unlawful fee or a wrongful seizure, ultimately belongs in front of a judge, not a complaints handler.

Throughout, log dates, keep every letter and email, photograph anything relevant and note the name of each person you deal with.

Contacting and paying CDER safely

Source every phone number and web address yourself: type cdergroup.co.uk directly or find the firm on your council's recovery pages. Numbers arriving by unexpected text, and payment links sitting in search adverts, are how impersonation scams harvest exactly this kind of payment.

With several debts in play, pin down which one your money will clear before it leaves your account, along with the current stage, the fees inside the figure, and a payment reference. Keep the receipt, and ask for written confirmation of what the payment changes.

Nothing about a doorstep visit requires opening the door to pay; card and phone payments work from your side of it.

Your CDER action plan

Everything below is cheaper and easier while the notice period is still running, so start today.

1. Authenticate the letter: company number, agent certificate, and above all one phone call to the council on its own published number.
2. Pin down which debt it is and the order or warrant behind it.
3. Audit the fees against the statutory scale, applying the regulation 11 rule wherever CDER holds more than one of your debts.
4. Wrong debt? The council gets a written challenge now, with evidence attached.
5. Right debt, impossible amount? Build the income and expenditure figures, then offer what they support.
6. Vulnerability in the household goes to CDER and the council in writing immediately, before any visit.
7. Gather finance, lease or ownership documents for any car that is not legally the debtor's to lose.
8. Never put your name to a controlled goods agreement whose schedule you have not read item by item.
