The UK has no legal minimum efficiency for new boiler installations since 2022, but the Building Regulations Part L still effectively requires a minimum 92% ErP rating for gas boilers Since the UK left the EU, the previous minimum efficiency requirements under the ErP directive were removed from domestic law. However, the Building Regulations Part […]
A 12-litre-per-minute combi boiler fills a standard bath in roughly four minutes, while an 8-litre model takes nearly six minutes for the same task. When you turn on a hot tap, the flow rate of a combi boiler determines how quickly hot water arrives and how strongly it runs. This metric, measured in litres per […]
A new combi boiler costs between 2,000 and 3,500 pounds installed, including flue and controls. System boilers with a hot water cylinder cost 2,500 to 4,500 pounds. Prices vary by brand, output size, and complexity of the installation.
At 2026 energy prices, an air source heat pump with a COP of 3 costs roughly the same as a gas boiler to run. With electricity at 24.5p per kWh and gas at 7.2p per kWh, the heat pump produces heat at about 8.2p per kWh compared to gas at around 8p per kWh including boiler efficiency. The 7,500 pound BUS grant makes the overall economics favourable.
Yes, but older houses often need some preparation. The key requirements are adequate insulation, possibly larger radiators or underfloor heating for lower flow temperatures, and sufficient outdoor space for the external unit. A professional heat loss survey will determine what upgrades are needed.
The BUS provides 7,500 pounds towards installing an air source or ground source heat pump. Your home must have an EPC, be replacing a fossil fuel heating system, and use an MCS-certified installer. The property must be in England or Wales and you cannot have previously claimed a renewable heat incentive.
Air source heat pumps typically last 15 to 20 years, while ground source heat pumps can last 20 to 25 years. A well-maintained gas boiler lasts 10 to 15 years. Heat pumps have fewer moving parts and require less maintenance.
How Heat Pumps and Gas Boilers Compare on Running Costs An air source heat pump (ASHP) produces 3-4 units of heat for every unit of electricity consumed, measured as a Coefficient of Performance (COP). At current UK energy prices with electricity at 24.5p/kWh and gas at 6.4p/kWh, a well-installed heat pump costs approximately the same […]
