LPG boiler. Replacement req.

[Lord Elmo]

I have just had a terminal sticker put on my old Vaillant VCW25/1 LPG combi.
Therefore I need a new one.
I installed the last one, but I don't want to do it again.
I therefore need advice. Anyone around the cotswolds who wants to quote?
What type of boiler should I look for?
While I am looking on the net, how do I work out what type / size to go for?
Thanks
