I am sure this will be welcome by some of those in rural areas on fossil fuels but for us is a bit late. Rural house tend to be old, cold and draughty the money would be better spent on energy conservation first.We are on LPG in bottles and with a gas bill of £300 pa would not make sense for us. We are around break even point on electricity from PV. There is a move by our supplier to go to a mix with bio gas so hopefully will reduce our low C footprint even lower. We threw everything we could at our build so that we needed little in terms of heating demand. I think it is unwise to put one's eggs all in one basket and rely on the electricity grid for everything. During that "blast from the east" a couple or more years ago they had to evacuate families from passive houses because the had no power to heat their homes. We are on an agricultural holding we grow vegetables for local sale at the gate using regenerative horticulture.We do not have cattle but our grass does go to feed a neighbour's cows. Our carbon footprint is probably around zero possibly negative. Everything in life is a balance and net zero to my mind has just swung too far the wrong way.

I suspect we're close to the cusp of no-one wanting a replacement oil boiler, maybe even gas too - just like seems to be happening right now with new ICE cars. Manufacturers argue for delay (existential, to stay competitive against far-east competition), govt gives in, public decides otherwise, manufacturers left scrambling to catch up with far-east, who are selling all the EVs they can ship (note, not all they can manufacture - that's sorted).
