I realise that it depends upon how well insulated the property is, but
it would cost me less in gas to keep my flat at a constant, say slightly
less than comfortable 16 degrees, than pay for this telecommunications

In terms of climate change, that would be totally inappropriate!


The flat is in a converted mansion which is Grade II Listed, so the scope
for insulating as well as we would like is limited.

at reasonable cost perhaps

but I doubt that the listing makes it impossible
