Air Source Heat Pump Installation
Efficient, low-carbon heating for your home
An air source heat pump costs £8,000–£14,000 installed, but the £7,500 Boiler Upgrade Scheme grant (£9,000 until March 2027 for an oil- or LPG-heated home with no mains gas connection) and 0% VAT bring the net cost to roughly £500–£6,500 for most East Anglia homes. Running at 300%+ efficiency, a heat pump typically beats oil and matches or beats gas on running costs.
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 standard £7,500 Boiler Upgrade Scheme grant; an oil- or LPG-heated home with no mains gas connection gets £9,000 until March 2027, a further £1,500 off. Includes installation and commissioning.
| 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
The MCS-certified heat pump installer applies for the Boiler Upgrade Scheme grant, securing your voucher (£7,500, or £9,000 for an oil- or LPG-heated home with no mains gas connection until March 2027) 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, 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)

The £9,000 heat pump grant for oil- and LPG-heated homes in East Anglia
The Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump in England and Wales. Until March 2027 it pays an extra £1,500, making £9,000, when both of two conditions are met: the home is heated by oil or LPG, and it has no mains gas connection. It is one grant per property, a hybrid system that keeps a gas boiler alongside the heat pump does not qualify, and an air-to-air heat pump gets £2,500 instead (gov.uk, Boiler Upgrade Scheme: what you can get).
That extra £1,500 is aimed at a kind of home that is far more common here than in England as a whole. In the 2021 Census, 3.2% of households in England relied on oil as their only central heating. The share was 17.3% in Norfolk, 13.2% in Suffolk and 9.3% in Cambridgeshire, and several rural districts were much higher (ONS Census 2021, table TS046):
- Mid Suffolk: 30.3% of households heated by oil only
- King's Lynn and West Norfolk: 25.1%
- North Norfolk: 24.6%
- South Norfolk: 24.2%
- Breckland: 23.7%
- West Suffolk: 16.6%
- East Cambridgeshire, where our Isleham base is: 16.4%
What the oil and LPG uplift means for your quote
Both conditions are about the property: what the home is heated by today, and whether a gas main is connected to it. A house with a mains gas connection that happens to run an oil boiler does not get the extra £1,500.
Norfolk, Suffolk and Cambridgeshire also have far more detached housing than England: 38.7%, 35.2% and 35.9% of households lived in a detached house or bungalow in the 2021 Census, against 22.9% nationally (table TS044). Detached homes tend to have more room outside for the heat pump unit.
At the free survey we confirm how the home is heated and whether it has a gas connection, then quote the net price with the right grant deducted: £7,500 as standard, or, for an oil- or LPG-heated home with no mains gas connection, £9,000 until March 2027.
Frequently Asked Questions
How does the Boiler Upgrade Scheme work?
The BUS provides a £7,500 grant towards air source heat pump installation, or £9,000 until March 2027 if your home is heated by oil or LPG and has no mains gas connection. Your MCS-certified heat pump installer 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 to pass the MCS 020 a) sound calculation: no more than 37 dB(A) one metre outside a neighbouring habitable room window or door. 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.
