Well, except the the radiators and some of the pipework,
that's a complete new central heating system.

I would find a local independant plumber and ask for a quote
for replacing the boiler. They'll still do more than just that,
but maybe get away with less than EDF and without the large
company overheards.

You still didn't reply to my question about where the expense
arises in the current system, maintenance, servicing or fuel.

The boiler is serviced once a year - normal cost for new or old boiler,
I presume.
Annual spend on gas about 800 quid
breakdowns - non-yet, but the system is very old and will *need* to be
replaced sometime soon I imagine.

So far nobody has mentioned the electricity only route, and whether that
might be viable. I guess the water radiators would have to go, but so
would the cost of the new boiler and the annual servicing.
Anybody know anything about economy 7 or 10 or whatever it's called
these days? My experience E7 heating is that it's crap, but hot water
has been excellent.
