Roger speaks with Duncan, a homeowner left without heating for more than 2½ years after a disastrous air-source heat pump installation under the UK Eco4 government scheme.

Installers got the heat-loss calcs wrong, fitted undersized radiators, never commissioned the system, and even added solar panels without checking the roof structure — causing further damage. The result: a cold home, big bills, and emergency repairs.

This isn’t an isolated case. With minimal inspections and installers chasing grant money over quality, thousands risk poor installs, damp, and structural issues — with no real safety net.

Duncan has now launched a charity to support others caught in the same situation and to push for urgent reform of government-backed retrofit schemes.
