There is some logic - depending on the room sizes, the radiators need to be different sizes and therefore cost different amounts. We're just about to get two upstairs rooms fitted out and were told by the plumber that the 3 other identical rooms that were fitted by a plumber were far too powerful and over the top (we're in France btw, and sounds like we're in a fairly similar situation).
We're sitting on several quotes (did you get more than one quote to compare?) for a 42kw wood pellet boiler to heat a similar size of house. The boiler installation, 3000l water tank to run everything off, silo to hold 10 tonnes of pellets, electrics (it will be housed in a barn until we rennovate that) and all plumbing between buildings averages around 30k. That's with no radiators.
We've had experience with several French plumbers and don't find they're pulling the wool over our English eyes. Some are better than others, and some will actively try to advise you on the best/cost efficient solution, whereas others will just put stuff where you tell them to. It takes time to sound out who to listen to.
The danger of thinking you can get an English plumber over to do it more cheaply is that depending on where you live, there are local nuances to think about. With us, it's the long cold alpine winters that Brits just aren't used to and can throw up some interesting challenges.
