There are only three ways to get ADAC to issue a CDP:
- to a vehicle/motorbike registered in Germany (that's obviously the bulk of what they do in CDP's)
- to a Netherlands registered vehicle (this is because the NL doesn't have an organization that has agreed to issue CDP) I got two CDP like this
- in theory to a UK registered vehicle if the RAC says it is OK to do that (this is what they seem to have told people: I haven't personally seen this in writing)

Also in theory one could get a CDP from the another EU AA (see list on FIA website), if they were willing. They probably have the same rule that ADAC/RAC has, that you need a waiver. Is worth checking.

I really suggest that anyone who is trying to get a CDP from the UK go look on the FIA website and spend some time on it. And even call-up the FIA offices and discuss the problem.
The information on costs of CDP's (RAC vs ADAC etc) would be a good thing to discuss: you might find a reasonable person there.

The other possibility is that you look thru the list of places where they issue other types of FIA instruments in the UK (not just for CDP, but other stuff). The website lists SIX UK clubs that have membership of FIA for "mobility":
Federation Internationale de l'Automobile[0]=field_memberclub_category%3A131&f[1]=field_memberclub_xml_country%3AUnited%20Kingdom

You can be a member of FIA for other reasons than granting CDP's. Perhaps one of these other organizations might be willing to issue a CDP.
It's worth asking them, although I suspect it's a long shot.

But the problem is that what we want is a hassle for all concerned. There's quite a bit of risk involved for whatever club does it. Sure in theory it's covered by the insurance policy that covers the guarantee, but insurance is never 100% perfect. And they do make an admin charge: but these things are a big hassle.

Look at the people who have been posting on this forum. No offence, but I understand one of them has had at least one, if not two challenges to their CDP. So either they made a mistake or the country they went thru did. Or it was an attempt to try to get money for nothing by the country involved. But either way, a huge hassle for the RAC. I know that ADAC have quite a few issues with CDP's and the people they gave them to not following the rules. I'm amazed they are still so friendly!

Both the RAC and ADAC do this as a service, and sure that's what they are supposed to be doing. But people like us are a very small part of their membership, and are very demanding too.

I think that this issue is going to take quite a bit of work to resolve: I have my doubts that it will be solved by just discussing things on this forum, or searching the internet. It will take some phoning and homework. And maybe paying for a lawyer to challenge the RAC, or else FIA itself.

FIA has procedures where you can make a claim, as well as an appeal. It seems possible to challenge how RAC is administering the CDP on FIA's behalf. Again: look thru the FIA website.

Perhaps the thing to do is the UK guys who need the CDP now get together and pool their money to pay for a lawyer. And ask for donations from other interested people (I'd pay towards it). First do the homework though on what is going to be needed.

I don't need a CDP within the next 12 months, so I'm not going to volunteer to spearhead that. And I will swap my registration to NL before I pay the RAC these crazy amounts.

Best of luck.
