From scenarios of boiler installations that have been posted in the
last few months it seems that the target price ought to be at around
£1500 - 1800.

I got a boiler fitted (Ideal Icos) in a slightly different location for
£1100, with an additional £100 cashback, making it £1000. I've never seen
anyone work so fast. He replaced the boiler, pump and hot water cylinder. He
turned up at 8.00 and was gone just after lunch. I think he intended to fit
another boiler in the afternoon.
