    The Guardian isn't 'the media' but this is a turnaround for decades of media wisfom that domestic retrofit is a) ignored in housing resale market prices, or even b) regarded as suspect encumbrance.


    "Analysis of 5m house sales in England and Wales found that installing an air-source heat pump could increase the value of a home by about £5,000-£8,000, solar panels could increase it by between £1,350 and £5,400 and an electric vehicle charging point could increase it by about £5,000." Presumable additive?

    "The Energy Saving Trust estimates that ... electric vehicle charging points [cost] about £1,000" - for £5000 resale boost!

    Judging my spend on green upgrades not worth it but then did not do it to add value. I reckon would need an uplift of around 25K at least to get it back on house sale.

    House valuation is an art not a science and it must be nearly impossible to assess what is and isn’t influencing the value.

    Two identical house one with end of life wood windows and with replacement windows costing/worth thousands valued the same as in same area with same number of bedrooms.

    The valuation system is a mystery to me

    Estate agents and suchlike try to put a price on a house, but ultimately the question is how much somebody will actually pay for it, regardless of what is being asked. The asking price may get people through the door (or not!) but what they see and are told matters more.
    The methodology is a little suspect if I understood it right. They looked at sale prices and found that houses with car chargers sold for a couple of % more. (2% of average house price => £5k). They didn't ask whether recently-refurbished houses sell for more money, or whether houses with off-street parking sell for more money, or whether car chargers are more likely to be found in those houses.

    They admit that they have guessed that the apparent price rises due to these different ecobling items might be additive, but that there is no evidence for this.

    Isn't the house price more to do with how much a person who wants to buy the house can borrow rather than is willing to pay? The massive inflation in house prices is IMHO more to do with this than the houses worth.
