Now all I have to do is find a CORGI person who doesn't want 1200 quid
(labour) to install and commission a boiler (just the boiler, I'll be
doing
the rest).

Or I'll be doing that myself too.

Legal.
However some boiler manufacturers are being a pain..
Ravenheat give a three year warranty if its fitted by a Corgi engineer
but not if you do it yourself.
I suspect that this is an unfair condition if someone challenged it in
court.

If you are not buying it direct from Ravenheat then you have no contract
with them, and their Ts & Cs are not really relevant. Your claim is on the
retailer.

True, but its a lot easier if you can just phone for a service engineer.

They also state it has to be fitted correctly just to cover for the
stupid Corgi engineers that are out there.

£500 for a new boiler but if I fit a condensing one I also need new rads.

Are your rads already bordering on being undersize? If not I would be
tempted to try it as it is first - you may find them large enough for the
vast bulk of the time.

They wouldn't meet my original design with a mere 30C temp difference, they
have 55C ATM.
Their outputs will be about 50% less.
Just as well its designed to work down to -10C or it would be very
undersized.
