Heating & Cooling Guides for 2026
Boiler replacement, air source heat pumps and the £7,500 grant, radiators, underfloor heating and air conditioning — every 2026 UK heating decision, costed.
Essential Heating & Cooling Pages
A replacement combi boiler starts from around £2,000 installed in 2026, while air source heat pumps start from around £7,000 before the Boiler Upgrade Scheme grant. Which is right depends on your home's insulation, radiators and how long you plan to stay.
Running costs matter as much as install costs: these guides compare gas, heat pumps and electric options on both, alongside air conditioning, underfloor heating and hot-water cylinders — all at real 2026 UK prices.
