I phoned A Plan today for a quote after speaking to Dan at Busfest. My (hopefully) soon to be bought T6 150 Highline Camper with use as a main vehicle and a value of £38K came out at £480ish or £430 if I join the Caravan Club. I'm pleasantly surprised seeing as my 2011 T5 van is £350, this is my first quote but I must say Jessica,who I spoke to, couldn't have been more helpful so a big thumbs up to A Plan. Also thanks to everyone who recommended them. Cheers.
