IMO the majority of houses in the UK are not special cases and a good, experienced ASHP heating engineer should be able to look at a house, ask a few questions and give an adequate estimate of sizing cost that is good enough for an initial quote.

Definitely.  Start by asking for the current annual consumption (or better still smart meter readings) and heating pattern.  That will give an estimate which will, in many cases, be better than the current method and, imho, should in every case be used to sense check the current method and in some cases should be used instead of the current method.
