How Do Heat Pumps Work?

Heat pumps extract renewable heat from the air or ground outside your home and use it to heat your rooms and hot water - like a fridge in reverse.

Extract Heat

The heat pump absorbs renewable heat energy from the outside air (ASHP) or ground (GSHP), even in winter.

Amplify

A compressor concentrates the heat energy, raising it to a useful temperature - delivering 3-4 kWh of heat for every 1 kWh of electricity used.

Heat Your Home

The concentrated heat is transferred to your central heating system - radiators, underfloor heating, or warm air.

Hot Water Too

Heat pumps also provide domestic hot water via an integrated or separate cylinder, replacing your boiler entirely.

Air Source vs Ground Source

Both types are highly efficient. Here's how they compare to help you decide which is right for your home.

Feature Air Source (ASHP) Ground Source (GSHP)
Cost (before grant) £8,000-£14,000 £15,000-£35,000
BUS Grant £7,500 £7,500
Net cost (after grant) £2,500-£6,500 £7,500-£27,500
Efficiency (COP) 2.8-3.5 3.5-4.5
Installation time 1-3 days 1-2 weeks
Space required External wall space Large garden area
Lifespan 20-25 years 25-50 years
Noise 40-50 dB (quiet) Silent (outdoor unit)

Pros & Cons of Heat Pumps

An honest look at heat pump advantages and things to consider before switching.

Advantages

  • £7,500 Boiler Upgrade Scheme grant available
  • 3-4x more efficient than gas boilers - lower running costs
  • Reduce carbon emissions by up to 75% vs gas heating
  • Provides both heating and hot water - replaces your boiler
  • Works year-round, even in freezing temperatures
  • Future-proof - UK banning new gas boilers in new builds from 2025
  • Can provide cooling in summer (some models)

Considerations

  • Higher upfront cost than a gas boiler (but grant helps significantly)
  • Some radiators may need upgrading for optimal performance
  • Best results in well-insulated homes (installer will assess)
  • External unit produces some noise (similar to a fridge)
  • Need outdoor space for the external unit (ASHP) or ground works (GSHP)
  • Requires a hot water cylinder (if you currently have a combi boiler)

Boiler Upgrade Scheme (BUS)

£7,500 government grant towards your heat pump installation

Eligibility Requirements

  • Property in England or Wales
  • Replacing a fossil fuel heating system (gas, oil, LPG, electric)
  • Valid EPC with no outstanding cavity wall or loft insulation recommendations
  • Must use an MCS-certified installer (all ours are)
  • Your installer applies for the grant on your behalf

Heat Pump FAQs

Answers to the most common questions about heat pumps for UK homes.

An air source heat pump typically costs £8,000-£14,000 installed. After the £7,500 BUS grant, the net cost is often £2,500-£6,500. Ground source heat pumps cost £15,000-£35,000 before grants, making ASHP the more popular choice for most homes.
The BUS grant provides £7,500 towards the cost of an air source or ground source heat pump in England and Wales. Your MCS-certified installer applies on your behalf. The grant is deducted directly from your installation quote - you never need to pay upfront and claim back.
Yes, especially with the £7,500 BUS grant. Heat pumps are 3-4x more efficient than gas boilers, typically saving £500-£900/year on heating. They future-proof your home as the UK transitions away from fossil fuel heating. With the grant, payback can be as little as 3-5 years.
Yes. Modern air source heat pumps work efficiently down to -20°C and are widely used across Scandinavia. In the UK, where temperatures rarely drop below -5°C, they perform extremely well year-round. Efficiency drops slightly in very cold weather but remains far better than direct electric heating.
An air source heat pump outdoor unit is roughly 1m × 1m × 0.4m - about the size of a large air conditioning unit. It needs around 1m clearance for airflow and is typically placed against an exterior wall. Inside, you'll need space for a hot water cylinder if you don't already have one.
Not necessarily. Heat pumps run at lower water temperatures (35-55°C vs 65-80°C for boilers), so some radiators may need upsizing. A good installer will do a room-by-room heat loss calculation during survey. Many homes only need a few radiators upgraded. Underfloor heating is ideal with heat pumps.
Modern ASHPs produce about 40-50 decibels at 1 metre distance - roughly the same as a quiet conversation or fridge. Planning rules require installation at least 1 metre from a property boundary. Most homeowners report barely noticing the sound after the first few days.
Air source heat pumps (ASHP) extract heat from outside air - they're cheaper, quicker to install, and suitable for most homes. Ground source heat pumps (GSHP) extract heat from underground via buried loops - they're more efficient (COP 3.5-4.5 vs 2.8-3.5) but cost significantly more due to ground works. ASHP is the right choice for most UK homes.
