Heat Pumps — Future-Proof Heating at 300% Efficiency

Air source heat pumps extract free heat from the outside air and deliver three units of heat for every one unit of electricity used. With a £7,500 government grant, the switch has never been more affordable.

Gas boilers have been the standard heating system in UK homes for decades, but rising gas prices and the UK's commitment to net zero are driving a shift towards heat pumps. Air source heat pumps operate at around 300% efficiency — for every 1 kWh of electricity consumed, they produce approximately 3 kWh of heat. With the Boiler Upgrade Scheme offering £7,500 towards installation costs and the government planning to phase out new gas boiler installations, heat pumps represent the future of home heating in the UK.

What Is Heat Pumps?

An air source heat pump (ASHP) is an electrically powered heating system that extracts heat energy from the outside air — even when temperatures are as low as -15C. It works on the same principle as a refrigerator but in reverse, using a compressor and refrigerant cycle to concentrate low-grade heat from the air and deliver it at a higher temperature to your central heating and hot water system. Modern ASHPs achieve a Coefficient of Performance (COP) of around 3.0, meaning they are approximately three times more efficient than a gas boiler.

How It Works

Home Assessment

An MCS-certified installer surveys your home to assess insulation levels, heating demand, radiator sizes, and the best location for the outdoor unit.

System Design

A bespoke heating system is designed to match your home's heat loss calculations, including any radiator upgrades or underfloor heating recommended for optimal performance.

Installation

The outdoor heat pump unit is installed on a concrete base, connected to your internal heating system, and integrated with a hot water cylinder. Installation typically takes three to five days.

Commissioning

The system is tested, flow temperatures optimised, and controls configured. You receive a full handover including how to operate the system efficiently.

Is It Right for My Home?

Air source heat pumps are suitable for most property types, including detached, semi-detached, and terraced homes. The property should have reasonable insulation levels (ideally loft and cavity wall insulation) to ensure the heat pump operates efficiently. You need space outside for the unit, typically alongside a wall with adequate airflow. The £7,500 Boiler Upgrade Scheme grant is available for homes in England and Wales that are replacing a fossil fuel heating system and have a valid EPC.

Key Benefits

Lower Running Costs

Save up to £500 per year compared to a gas boiler, with savings even greater for homes currently using oil, LPG, or electric heating.

£7,500 Government Grant

The Boiler Upgrade Scheme provides £7,500 towards the cost of an air source heat pump, reducing the net cost to as little as £3,000 to £6,500.

300% Efficient

For every unit of electricity consumed, a heat pump delivers around three units of heat — making it roughly three times more efficient than a gas boiler.

Heating and Cooling

Many air source heat pumps can provide cooling in summer as well as heating in winter, offering year-round climate control from a single system.

Future-Proof

With the UK government planning to phase out new gas boiler installations, switching to a heat pump now puts you ahead of regulatory changes.

Slash Carbon Emissions

Heat pumps produce significantly lower carbon emissions than gas boilers, especially as the electricity grid continues to decarbonise.
