Our local council are supplying discounted high efficiency boilers

Any of you experts got any impartial advice ?
My gut instinct is to try and source spares for my existing boiler
to keep it going as long as possible.

It really depends on how much you are spending on gas. You can
probably reckon on your existing boiler being 65-70% efficient at
best, against 90% for a new condensing boiler so if you do the swap
your bills will probably drop by about 25%. Do the arithmetic and
you'll see what the likely payback period is.

Your best way of saving money is probably to ditch the BG *** and
find a local guy who will sort out any problems if needed.
