Air Source Heat Pump Installation
Efficient, low-carbon heating for your home
About Air Source Heat Pump Installation
Air source heat pumps extract heat from the outside air to warm your home and hot water, operating efficiently even in temperatures as low as -20°C. With the £7,500 Boiler Upgrade Scheme grant, switching to a heat pump has never been more affordable.
Key Benefits
Heat Pump Costs (After BUS Grant)
Net costs after the £7,500 Boiler Upgrade Scheme grant. Includes installation, commissioning, and MCS certification.
| Property | System Size | Net Cost | Annual Running |
|---|---|---|---|
| 1-2 bed | 5-6 kW | £0 - £2,500 | £610 - £720 |
| 3-bed semi | 8-10 kW | £500 - £5,500 | £610 - £720 |
| 4-bed detached | 10-12 kW | £3,500 - £10,500 | £610 - £720 |
Running costs assume electricity at 24.5p/kWh. Actual costs depend on insulation levels and usage patterns.

Home Assessment
We assess your home's insulation, radiators, and heating requirements to determine the right heat pump size and any preparatory work needed.
BUS Application
We handle the Boiler Upgrade Scheme grant application, securing your £7,500 voucher before installation begins.
Installation
Installation typically takes 2-4 days. We install the outdoor unit, indoor components, update your hot water cylinder, and upgrade radiators if needed.
Commissioning
We commission the system, optimise settings for your home, register with MCS, and provide full training on your new heating system.
Typical Timeline
Works Well With
Power your heat pump with free solar electricity. Reduces running costs by up to 60%.
Low-temperature distribution is the ideal match for heat pump efficiency.
Reduce your heat loss first to get a smaller, cheaper, more efficient heat pump.
Well-insulated homes need MVHR to maintain fresh air. Adding heat recovery ventilation reduces the heat pump load by up to 15%.
Financing
£7,500 BUS grant deducted upfront. Net cost from £500 for a 2-bed property. 0% VAT applies. Finance available on remaining balance.
Warranty
- 7-year manufacturer warranty (Daikin, Vaillant)
- 10-year workmanship guarantee
- MCS certification included
- Annual service plans available
Popular Combinations
Combine services for greater savings. All figures based on typical East Anglia households.
Heat Pump + Solar
Power your heat pump with free solar electricity. Running costs drop by up to 60%.
Heat Pump + UFH + Insulation
The optimal heating combination. Low-temperature distribution in an insulated envelope.
Heat Pump + Solar + Battery
Near-zero energy bills. Generate, store, and heat entirely from renewable sources.

Frequently Asked Questions
How does the £7,500 Boiler Upgrade Scheme work?
The BUS provides a £7,500 grant towards air source heat pump installation. Your installer (us) applies on your behalf, and the grant is deducted from your invoice. You never handle the money directly. The scheme runs until at least March 2028.
Will a heat pump heat my home in winter?
Modern air source heat pumps operate efficiently down to -20°C. East Anglia rarely sees temperatures below -5°C. Your heat pump will comfortably heat your home year-round, including the coldest winter days.
Do I need to upgrade my radiators?
Heat pumps operate at lower flow temperatures than gas boilers, so some radiators may need upsizing. During our home assessment, we calculate heat loss for every room and identify any radiators that need upgrading. Many homes need only 2-3 radiators changed.
How much does a heat pump cost after the grant?
A typical air source heat pump installation costs £10,000-£18,000 before the grant. After the £7,500 BUS grant, your net cost is typically £2,500-£10,500 depending on system size and any additional work required.
How noisy are air source heat pumps?
Modern air source heat pumps from manufacturers like Daikin, Vaillant, and Mitsubishi operate at 40-55 dB at 1 metre — comparable to a quiet conversation or a fridge. Permitted development rules require the unit not to exceed 42 dB at the nearest neighbour boundary. We always calculate noise levels during our survey.
Can I pair a heat pump with solar panels?
This is one of the most effective combinations available. Solar panels generate electricity during the day, which powers your heat pump. A 4kW solar system can offset 60-80% of a heat pump's annual electricity consumption, dramatically reducing running costs to as little as £200-£300 per year for heating.
