It's not a condensing combi, and I don't have a hot water tank. I've
had cavity wall insulation installed last summer, and had my loft
insulation upgraded last winter when the new boiler was installed.
It's not double glazed, but saying that, it wasn't double glazed when
it was heated with oil either...

I'm a bit lost as to where to look next! Oil boilers???

That might be jumping from the frying pan into the fire! Oil has gone
up a lot over the last two years...

Worth checking that the loft insulation is at least a foot (IIRC the
minimum for new builds) and all external doors and windows are
properly draught proofed.

Also secondary double glazing (eg magnetic snap on glazing) would help
if the windows are particularly large.

With the above it should also be possible to switch the heating off
overnight without it getting too cold.

cheers,
Pete.
