Air Source Heat Pumps

In the UK, the cost of an air source heat pump (ASHP) depends on factors such as the type of system, property size, and installation complexity. Here’s an overview of the typical costs:

1. Equipment Costs

• Air-to-Air Heat Pump: £2,500–£6,000
  • Heats and cools air but doesn’t provide hot water. Best for smaller or well-insulated properties.
• Air-to-Water Heat Pump: £7,000–£12,000+
  • Provides both heating and hot water, commonly used for central heating.

2. Installation Costs

• Basic Installation: £2,000–£4,000
  • For straightforward installations where minimal system upgrades are required.
• Complex Installations: £5,000–£8,000+
  • Costs increase if significant changes to the property’s heating system are needed (e.g., underfloor heating, upgraded radiators).

3. Running Costs

• Typical yearly running costs range from £500–£1,300, depending on:
  • Home insulation quality.
  • Energy tariffs.
  • Heat pump efficiency (COP).

4. Additional Costs

• Hot Water Cylinder: £1,000–£2,000 (if needed).
• Upgraded Radiators or Underfloor Heating: £2,000–£5,000 (depending on the size and number of rooms).
• Electrical System Upgrades: £500–£2,000 (if the current system isn’t compatible).

Government Incentives

The UK government offers support for heat pump installation through schemes like:

• Boiler Upgrade Scheme (BUS):
  • £7,500 grant for air source heat pumps.
• Energy Company Obligation (ECO):
  • Additional financial assistance for eligible low-income households.

• ASHPs work best in well-insulated homes to maximize efficiency.
• Larger or older properties with poor insulation may need additional upgrades like wall or loft insulation.
• They can replace traditional boilers but may require changes, such as larger radiators or underfloor heating.

Potential savings depend on:

• Your current heating system (e.g., electric or oil heating savings are higher).
• The heat pump’s efficiency (often 300–400% efficient).
• Energy tariffs (moving to a low-rate electricity tariff can maximize savings).
• Typical annual running costs range from £500–£1,300 for a well-insulated home.

The UK offers grants for air source heat pumps through the Boiler Upgrade Scheme (BUS).

This program provides £7,500 to help with installation costs. To qualify, your property must be in England or Wales and have a valid Energy Performance Certificate (EPC) with no recommendations for loft or cavity wall insulation. New builds generally don’t qualify, except for self-builds.

The grant is applied for by your installer, reducing the upfront cost. The scheme runs until 2025 or until funding is exhausted.

Additional support may be available through the Energy Company Obligation (ECO) for low-income households.

1. The heat pump draws warmth from the outside air.
2. This heat is then delivered to your central heating system.
3. Hot water is distributed to your radiators or underfloor heating, while any excess is kept in a hot water cylinder.
4. The stored hot water is available for your showers, taps, and baths.
