If i quote for a boiler change and try for £300 labour then i know someone who works for british gas or a local council engineer will do it for less. also on top of that in devon /cornwall its like a retirement home for plumbers/engineers so lots of competition.To charge £1000 for heating pack is ideal scenario but your going to find it hard to get any work at those ytpe of rates unless its contract work.
