> Another major problem is the quality of building in the UK, mainly driven by a lack of tradespeople, and simply not having the skills to install to the quality levels required by thermally efficient houses like installing a membrane with zero holes in it, using the correct tapes, designing, installing and maintaining heat pumpes and various other things. I agree with the sibling comment this is an incentive problem rather than a skill problem. If house builders can cut corners they will. If they can sell a house for the same cost without the fancy new insulation gear they will. This is why your bit about regulation is needed because otherwise the things you list won’t happen. Home chargers are a good example which the govt deemed necessary for new builds, the skill will be there for that and without the regulation I’m not sure most builders would have bothered, leaving people to retrofit one further down the line paying a higher cost. The skills for heat pumps will organically grow as regulation kicks in too. > why governments aren't keen to make large improvements in energy-efficiency regulations. The govt have been consulting with various business and institutions on future building standards you can view their response here: https://www.gov.uk/government/consultations/the-future-buildings-standard https://www.gov.uk/government/consultations/the-future-build.... But from it we've already had EV charging point requirements, ban on gas boilers, new homes in England will have to produce around 30% less carbon emissions, plus raising the standard for insulation.
