If you have received a letter, text, or visit from CDER Group, treat it as urgent but do not panic. CDER Group is an enforcement company, which means the stage of the case matters more than the company name alone.
Companies House lists CDER Group Limited as an active company with company number 04118149. The Companies House record also shows previous names including J.B.W. Group Limited and J.B.W. Enforcement Limited.
This guide was last checked on 26 April 2026 against Companies House, CDER’s contact page, CDER’s FAQs, GOV.UK bailiff guidance, and the Taking Control of Goods Regulations 2013.
Quick answer#
- CDER Group Limited is a real company. Check company number 04118149.
- CDER are enforcement agents, not ordinary debt collectors. Read the notice carefully.
- Do not rely on a number in a suspicious text. CDER says to use its official number to check.
- Entry powers depend on the debt. For most civil debts, first entry is usually peaceful entry only.
- Some debts need special handling. HMCTS court fines and penalties may not work the same way as credit cards or loans.
- An IVA may help with included qualifying debts, but it will not automatically solve every CDER case.

What debts does CDER collect?#
CDER’s contact page refers to several public-sector and penalty-related case types, including:
- HMCTS court fines
- Transport for London penalties
- National Highways Dart Charge penalties
- Other enforcement cases
The exact powers depend on the debt type. A court fine can be treated differently from council tax, a parking penalty, or a civil judgment.
Before paying or arranging a plan, check:
- Who instructed CDER
- The case reference
- The original debt or penalty
- The enforcement stage
- Any fees added
- The date the notice was sent
- Whether the address and personal details are correct
How to check if a CDER message is genuine#
CDER’s own contact page includes scam-warning advice. It says scammers may phone, text, email, or visit pretending to be from CDER and asking for payment.
If you are unsure:
- Stop before paying.
- Use CDER’s official website contact details.
- Do not rely on the phone number in a suspicious text or email.
- Ask CDER to confirm the case reference.
- Ask for the enforcement agent’s identity to be confirmed if someone visits.
This matters because enforcement messages can be frightening. Scammers rely on urgency. A real enforcement company should be able to verify the case through official channels.
Can CDER force entry?#
For most civil debts, enforcement agents usually cannot force entry on a first visit. GOV.UK says you usually do not have to open your door to a bailiff or let them in.
You should:
- Keep doors locked.
- Speak through the door if you are unsure.
- Ask to see ID and paperwork.
- Ask what debt they are enforcing.
- Ask what stage the case is at.
- Avoid signing a controlled goods agreement unless you understand it.
Some debts and situations have different rules. Court fines and commercial premises can be more complicated. If CDER is enforcing a magistrates’ court fine or another high-risk debt, get urgent advice.
CDER fees and enforcement stages#
For many enforcement cases in England and Wales, fees are added in stages. The exact fees depend on the type of enforcement and regulations that apply.
Common stages include:
- Compliance stage: a notice is sent and a compliance fee is usually added.
- Enforcement stage: an enforcement agent attends and further fees may be added.
- Sale stage: goods may be removed or sold if enforcement continues.
Always ask for a written fee breakdown. Check whether the fee stage matches what has actually happened.
Can an IVA stop CDER Group?#
An approved Individual Voluntary Arrangement can stop enforcement for included qualifying debts. However, CDER often deals with debts and penalties where the rules can be different.
An IVA may help if:
- The CDER case relates to a qualifying debt
- You have wider unsecured debts
- The debt is included in the proposal
- The IVA is approved by creditors
- The enforcement stage allows it to be stopped
An IVA may not be the right route if the CDER case is only a single penalty or court fine. Court fines, criminal penalties, and some public-sector debts may need specialist advice.
How to complain about CDER#
Complain to CDER first if you believe:
- The debt is not yours
- The notice went to the wrong address
- The fees are wrong
- An agent refused to show ID
- An agent threatened powers they did not have
- Vulnerability was ignored
- You were not given a proper chance to resolve the account
Keep:
- The notice
- Envelopes
- Texts and emails
- Payment receipts
- Agent names
- Dates and times of visits
- Photos of documents, if safe
You may also need to complain to the creditor, council, court, or public body that instructed CDER.
What to do now#
- Check the official CDER contact details.
- Confirm the case reference and original creditor.
- Ask for a full balance and fee breakdown.
- Check whether you received the required notice.
- Keep doors locked until you understand the powers.
- Get urgent advice if a visit is due or a court fine is involved.
- Compare wider debt options if CDER is one of several creditors.
Do not wait until goods are listed or removed. The earlier you act, the more options you usually have.
