CDER Group Complaints: How to Escalate the Right Way

CDER Group Limited, registered at Companies House under company number 04118149, describes itself as enforcing council tax, penalty charges and business rates for local authorities. It also collects unpaid magistrates' fines for His Majesty's Courts and Tribunals Service, which is independently confirmed: HMCTS appointed CDER Group as an Approved Enforcement Agency covering the London, Midlands and South East lots from 1 September 2020 (see the CDER Group profile for that source). That client mix matters more on this page than anywhere else, because CDER's published escalation route splits by client type rather than offering a single door for everyone.

What CDER's published procedure commits to

CDER's complaints page describes a two-stage internal process and asks complainants to use its online form, although it also accepts email to customercare@cdergroup.co.uk and post to CDER Group, PO Box 81793, London, EC3P 3GE. Complaints about magistrates' fines work have their own address, hmcts-complaints@contactcder.co.uk, which is worth using where it applies because those cases sit on a separate system.

The timescales the firm publishes are specific enough to hold it to. It says it acknowledges a complaint within 2 working days of receipt, aims to resolve the informal stage within 5 working days of that acknowledgment, and answers a formal-stage complaint within 20 working days of acknowledging that the case has moved to formal resolution. If a deadline passes with nothing, chase in writing and refer to its own published figure.

CDER's form asks for the specifics of what happened, the impact on you and your preferred remedy, so decide before writing what you actually want: a fee removed, a hold on the case, an apology, or the case sent back to the creditor. A complaint with a named remedy is harder to answer vaguely. The national standards for enforcement also expect the complaints route to be easy to find and free of obstacles, which is worth quoting back if the process itself becomes the problem.

Where CDER's procedure sends you afterwards

The unusual thing about CDER's published procedure is that it names a different external body for each kind of client:

• Council-instructed cases, which cover council tax, penalty charges, Transport for London debts and business rates, go to the local authority itself, and after that to the Local Government and Social Care Ombudsman if the council's handling still leaves the matter unresolved. The council can also recall the case entirely, which is a power CDER does not have.
• Central government cases, including HMCTS fines and National Highways debts, are pointed by CDER's procedure at CIVEA, the trade association of which it is a corporate member. Be aware before writing to CIVEA that its own complaints page says it is unable to consider complaints about its members, and that the Enforcement Conduct Board is now the body responsible for investigating them, so for these cases the working escalation is the Enforcement Conduct Board, once CDER's own process is exhausted.
• Anything that happened on or after 1 January 2025, whatever the debt type, can go to the Enforcement Conduct Board once CDER has responded.

Getting the ladder right saves weeks. A fines complaint sent to a council usually just comes back, and CIVEA itself cannot stop enforcement action or investigate an individual complaint, whatever a firm's procedure says.

The Enforcement Conduct Board and its deadlines

The Enforcement Conduct Board provides independent oversight of enforcement firms in England and Wales, and CDER has been an accredited firm since October 2023. CDER's procedure states the time limit for taking a complaint there: three months from when you could reasonably have been aware you had a complaint, or one month from CDER's final response, whichever is longer. That deadline is the reason not to let the internal stages drift, and if CDER's final response is slow in coming, keep your own dated records so the window can be shown to be open.

When a complaint is the wrong tool

If your real objection is that the debt itself is wrong, the complaint belongs with the creditor, because CDER can only collect what it was instructed to collect. If the objection is a fee, check the figure against the statutory scale first, since fee errors are usually corrected as account queries rather than conduct complaints.

Where an agent has breached the rules in Schedule 12, or has acted under a liability order, warrant or other instrument that turns out to be defective, a court route exists alongside any complaint: paragraph 66 of that Schedule allows the court to order goods to be returned and to award damages for the loss caused. That remedy can reach further than an apology, but the paperwork needs checking properly first, so take advice before issuing anything.

Two pages to read alongside this one

The generic complaint ladder, including how to word the complaint itself and what evidence carries weight, is in our guide to how to complain about a bailiff. What CDER can and cannot do at your door, their fee stages and how to verify a letter are on the CDER Group profile. If the situation is urgent, for example goods are about to be removed, get advice now rather than waiting for a complaints timetable to run.
