For years the writing was on the wall – diesel exhausts are harmful. It was clear that the days of diesel powered cars were numbered yet they continued to sell in great numbers. Until the penny dropped and they suddenly stopped selling with a collapse in registrations and residual values.

I predict a similar fate for energy inefficient houses where currently purchasers pay little, if any, regard to Energy Performance Certificates. The government has introduced a new Retrofit Standards Framework. Central to this is ‘PAS 2035 – Retrofitting dwellings for improved energy efficiency. Specification and guidance’. From June 2021 it will become compulsory for all certification bodies and TrustMark registered businesses to comply.
With new homes moving towards zero carbon, old homes will need to offer an increasing degree of energy efficiency if they are to sell. Energy efficient measures and the associated installation costs and costs in use will be a major consideration in valuing them. So factor these in when you come to buy and sell or you might be left with the bricks and mortar equivalent of an old diesel.
