The first lesson of the gas crisis is old and boring: the UK should get serious about insulating its leaky properties. If all homes that have energy performance certificate band D were upgraded to band C, the UK’s total gas demand would fall by 7%, and imports by 15%, the Energy and Climate Intelligence Unit calculates. Given the UK’s wretched record in insulation versus European peers, that sounds a small but easy win.
The second part – the supply side – is where the trickier stuff starts. The broad energy direction has been set towards nuclear and renewables, but there’s no getting away from the fact that gas will be in the mix for a long time yet. Virtually all transition scenarios imagine it, and you have to be an extreme optimist to believe UK consumers can quickly be converted to the joys of heat pumps.
