Home Energy Retrofits in Cornwall
Cornwall sees cold St. Lawrence winters and humid summers, and many of its homes were built when energy was cheap and insulation was an afterthought. HES helps Cornwall homeowners access approved cost-neutral retrofit programmes — no upfront cost required.
About this programme
About this programme in Cornwall
HES helps homeowners across Cornwall and the surrounding SDG counties understand whether they qualify for an approved retrofit programme. We coordinate the process from end to end. HES does not install anything itself — all work in Cornwall is completed by approved programme contractors.
If you'd like the full overview of how the broader programme works, our How It Works section walks through every step, and our FAQ answers the most common questions from homeowners.
Common upgrades
Common upgrades in Cornwall homes
Programmes vary, and not every home receives every upgrade. These are the retrofits we most often see help Cornwall homeowners lower their energy costs.
Insulation
A high-impact upgrade for many Cornwall homes — particularly older ones with original attic and wall insulation.
Heat Pumps
Heat pumps handle both heating and cooling efficiently, which suits a lot of Cornwall homes.
High-Efficiency Heating
Modern furnaces and boilers turn far more of their fuel into usable heat — useful in Cornwall's climate.
Smart Thermostats
Smart thermostats fine-tune when and how your Cornwall home is heated and cooled, without changing your habits.
Hot Water Systems
Efficient hot water systems trim a meaningful share of monthly energy use for most Cornwall households.
