A notice of enforcement from CDER Group means the council has authorised bailiff action to collect an unpaid parking penalty. You have a compliance period, usually 7 clear days, to pay, set up a payment plan, or challenge the enforcement.
This is a critical stage. If you did not receive the original PCN, notice to owner, or charge certificate, you may be able to file a statutory declaration at the TEC to have the case reopened. This would reset the case to an earlier stage where formal representations can be made.
Upload your notice and Parking Mate AI will check whether the enforcement chain was properly followed and whether you have grounds to challenge.
Was the original penalty charge notice properly served? If you never received it, the entire enforcement chain may be challengeable.
The council must have sent a notice to owner giving you the chance to make formal representations. If this was missed or defective, it undermines enforcement.
A charge certificate must be issued correctly and served on the right person. Errors at this stage can invalidate the enforcement.
Fees must follow the regulated structure: £75 compliance, £235 enforcement. Any overcharging or failure to link concurrent debts is unlawful.

Common questions about this enforcement firm and how to respond to their letters.
A notice of enforcement from CDER Group is the formal compliance notice that must be sent before an enforcement agent can visit your home. It gives you a compliance period, usually 7 clear days, to pay the debt or contact CDER Group to dispute it. This is the first stage of the bailiff enforcement process.
The compliance period is usually 7 clear days from when the notice is deemed served. During this period, you can pay the debt, set up a payment plan, or dispute the enforcement. The compliance stage fee is £75, which is the minimum you will owe if the debt is valid. After this period, the enforcement stage fee of £235 (plus 7.5% on amounts over £1,500) is added.
CDER Group can visit your home after the compliance period has expired, but they CANNOT force entry for a parking debt under the Taking Control of Goods Regulations 2013. They can knock on your door and ask to discuss the debt, but you do not have to open your door or let them in.
At the compliance stage, CDER Group can add a fixed fee of £75 to the debt. If the case moves to the enforcement stage (after the compliance period), the fee increases to £235 plus 7.5% of the debt above £1,500. These are the only regulated fees. Challenge any charges that exceed this structure.
Yes. Contact the council directly to dispute the underlying parking penalty. You can also apply to the Traffic Enforcement Centre (TEC) to have the case reopened if you did not receive the original PCN, the notice to owner, or the charge certificate. A successful application resets the case to an earlier stage.
If you did not receive the original PCN, notice to owner, or charge certificate, you may be able to file a statutory declaration or witness statement at the TEC to have the case reopened. This is one of the most important defences at the enforcement stage. Act quickly because time limits apply.
The notice of enforcement itself does not appear on your credit file. However, the underlying debt was registered at the TEC (part of the county court system), and if a county court judgment was obtained, that may already be on your credit record. The enforcement stage is separate from credit reporting.
Many enforcement agents, including CDER Group, will accept payment plans, especially during the compliance stage. Contact CDER Group during the 7-day compliance period to discuss arrangements. Getting a payment plan in place before the enforcement stage can save you the additional £235 fee.
Check CDER Group's fees against the regulated fee structure under the Taking Control of Goods Regulations 2013. If fees exceed the regulated amounts, or if multiple enforcement fees have been charged for debts that should have been "linked", complain to the council and the Enforcement Conduct Board.
