Now you've got at least one fairly comprehensive quote. Get some more
and eventually you will have the market price for somebody doing the job
for you. The EDF one doesn't seem bad considering the non-combi scope.
Bechmark it against BG and an independent. You may be able to find
cheaper. Only you can decide the value of going with a big name.

( I assume its you that has omitted the TRVs)

Yes, sorry.

To suppply and fit Belmont Terrier thermo controlled radiator valves on
all radiators excluding are where new wireless room thermostat is fitted.

I have just found another quote - £3600 - for basically the same thing
(but to include power-flushing). Interestingly, they include the "option"
of going with a combi boiler - that's only £300 cheaper at £3300

BTW I'm not justifying quotes only reflecting what appears to be market
reality but as a component of house value the cost is neither here nor
there. Question - do the rads appear at the bottom indicating sludge -
which may or may not be cleared by power flushing - never tried so can't
vouch.

You touched on maintenance but it hasn't been discussed much. FWIW I think
there are market realities here too. Factor in £13 or so per month for a
maintenance contract unless you are prepared to trust to "market realities"
when the chips are down. Again your choice. A DIYer might have a
different view.

Your most focussed advice has been is the boiler/system upgrade necessary.
Implicitly your answer has been not quite yet so if its under contract why
bother until forced? OTOH now is a good time of year and you are right,
eventually something will have to be done. And the electrical option is
daft.
