EU car registration in UK

i have registered my vehicle using NOVA service to tell HM Revenue and Customs (HMRC) ive brought the vehicle into the UK but now im stuck and would appreciate any help anyone can offer. next step is to  register and licence the vehicle with the Driver and Vehicle Licensing Agency and to fill in the required form i need a certificate of conformity but my vehicle supplier wont issue this as my car is 11 years old ... does anyone have and recommendations on how to proceed pls?

CoC usually has to be requested from manufacturer

If the vehicle comes from the EU and it's older than 10 years, you don't need a CoC.

Before completing the NOVA have you done the V55? If you haven't, please consider doing it so you can import the car iva free.

I am going through the same process, what a journey!
