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.
