Quite a few clubs these days use a Eurofox which according to their website is "a NON EASA annex II aircraft operating on a LAA or BMAA permit to fly". However your chances of being allowed to tow with no gliding experience are pretty minimal.
Agreed, and the rating may not be required to fly one but I don't know if that is licence dependant (EASA vs UK licence). The rating can only be added to an EASA licence.
As of 20 Nov 18, the following gliding clubs can deliver the sailplane towing course; Booker, Bicester, Cambridge, Deeside, East Sussex, Lasham, London.
