Before we moved into our current family house, our last permanent home was bought at the back end of 2013, and presented us with an ideal opportunity for a first foray into sustainable renovations.
As an old property we started by boosting all the internal and external insulation - something most people could do - before moving on to the installation of new windows, 10 kW of solar, a 12 kW air source heat pump, underfloor heating and two EV chargers.
Fast-forwarding to our current home, with the fabric of the building being pretty much as good as it could be, we were able to focus more on the tech we wanted.
As well as obvious upgrades in solar, heat pumps and EV chargers, we've gone on to install underfloor heating and I've personally changed around 75 downlights to LEDs!
You can read about various improvements below, but it's been satisfying to take the house from having a poor D rating EPC to a good B EPC and makes the effort worthwhile.
