Having a service whilst on site

From memory alone I think you can't? I think you can only have essential/repair/breakdown work done. But I would contact the club direct and check.

If it’s a CL, it will be entirely up to the CL owner but, with regard to club sites, I think Corners is right.

You will need to be on a Cl or private suite with the permission of the owners if possible  

It would not be possible on this clubs sites,

It may be allowed on affiliated sites with the permission of the owner

Afraid it is  a no on club sites been like this for about 6 or 7 years.

As other folk have said either cl or commercial site with owners permission.

Annoying. To be fair there is a caravan workshop near me I could take my FC to. Unfortunately they've not bothered to reply to my enquiry email. Nor has a mobile engineer that I asked for information from. So hard to give people money sometimes.
