Low-carbon air source heat pumps

Typically save £1,696 over 10 years(1) and produce 68% less carbon emissions(2) for a gas heated home

~~£8,999~~ £3,999(3) typical package price for a 3 bed home - Green Homes Grant deadline 31st March

An air source heat pump can save £1,696 over 10 years(1)

With the Green Homes Grant and RHI schemes subsidising installing an air source heat pump, there's never been a better time to get one

Reduce your heating bill and upfront cost

Daikin air source heat pumps are up to 4x more efficient than an equivalent gas boiler(4), so you can heat your home and water for a similar cost to gas
Thanks to the Green Homes Grant and Renewable Heat Incentive, you can claim up to £10,500 in subsidies(5) depending on your energy usage

Longer life & easier maintenance than a boiler

According to Energy Saving Trust, you can expect your heat pump to last 20 years or more(6) compared to 10 to 15 years for a gas boiler
We recommend a simple annual check by a qualified person

Better for the environment

An air source heat pump produces up to 68% less CO₂ than a gas boiler(2), so for a 3 bed home you can save the equivalent of 6 return flights from London to Madrid over a year(2)
Heat pumps heat your home and hot water even when temperatures outside are as low as -20ºC(7)

What is an air source heat pump?

An energy-efficient air source heat pump (ASHP) works like a fridge but in reverse. It absorbs heat from the outside air and circulates it through your heating system.

The pump uses electricity to run and can use one unit of electricity to generate up to 4x heat(4).

For an air source heat pump to be effective, and to claim on the Renewable Heat Incentive, you will need at least 150mm loft insulation to prevent heat escaping through the walls or roof.

Air source heat pumps you can trust

For our equipment, we've partnered with Daikin, the biggest manufacturer of air source heat pumps in Europe with products sold in over 150 countries.

And for added peace of mind, we're working with a network of highly trained Daikin installers who are all accredited by the Microgeneration Certification Scheme (MCS) and TrustMark certified, the Government Endorsed Quality Scheme, so you know they're thoroughly vetted and commited to good customer service, technical competence and trading practices.

Funding your air source heat pump

There's up to £10,500 in government subsidies available(5).

Under the Green Homes Grant, you can claim up to £5,000 for two thirds off the upfront cost to help pay for your heat pump. If you claim the Green Homes Grant, the remainder can be claimed through the Renewable Heat Incentive (RHI) over 7 years, otherwise the full amount can be claimed through the RHI.

With both schemes combined, there has never been a better time to get an air source heat pump. For those households with low-income, additional subsidies may be available.

What air source heat pump customers say

We love the Air Source Heat Pump, it provides a constant ambient comfortable temperature throughout the house. Now it’s always warm.

Anna Edwards, Bridgwater, Somerset

I am delighted with the efficiency and relatively quietness of the Air Source Heat Pump itself. It is an environmental and engineering marvel.

Peter Corkill, Canterbury, Kent

Is an air source heat pump right for your home?

Gas homes

If you have an old boiler and reasonably insulated home, then you can switch to an energy-efficient air source heat pump. Our trusted installers will recommend the right heat pump based on your needs and house type.

Oil or LPG homes

A hybrid heat pump could be the best option for you if your heating runs on Oil or LPG. A Hybrid upgrade simply adds a smaller heat pump to your home so you use less oil or LPG without overhauling your entire system.

Have you thought about insulation?

Any heating system is only effective if the heat it's creating doesn't escape through a poorly insulated roof or walls. Prevent heat loss and save up to £530 on your energy bills(8) by adding insulation to your home. You can also qualify for up to 66% off with the Green Homes Grant.

Get an exclusive zero carbon tariff

EDF is Britain's largest generator of zero carbon electricity(9). We've partnered with Daikin to offer an exclusive low-cost zero carbon tariff for our heat pump customers.

Once your new system is installed, Daikin or the installer will provide you with details on how to access the exclusive tariff.

Notes

Calculation is based on:
- Heat pump on offer is a package of 7KW air source heat pump with designed efficiency (SCOP) of 3.48, radiator upgrades, hot water tank and installation.
- Typical upfront price of £3,999 includes Green home grant discount of £5000, is for a property in the South of the UK with annual heat demand of 13,903 kWh consumption for heating and hot water, at least 150mm insulation and built between 1960-1980.
- Our expert installer will provide a more accurate assessment of heat pump cost & savings based on your individual needs and house type
- Boiler cost of £3,324 from recent govt study where we assume a non-combi boiler of 24KW and boiler efficiency of 84%
- It does not differentiate between bedroom sizes so its an average across all property types: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/913508/cost-of-installing-heating-measures-in-domestic-properties.pdf
- Heat pump lifetime is usually 15-20 years compared to boiler of 10 years
- Energy & carbon price assumptions from https://energysavingtrust.org.uk/about-us/our-calculations
- Car emission from UK Government GHG Conversion Factors for Company Reporting 2020, assuming 10,000 miles for an average size petrol car
- RHI subsidy of £7,068 (based on 10.1p/kWh)
Heathrow to Madrid, Spain is 1243 km one way.
BEIS - UK Government GHG Conversion Factors for Company Reporting 2020 - Air Travel with RF factor included states 0.378394 tonnes of CO₂ per economy passenger for a return flight.
The carbon difference between a heat pump and boiler is calculated as:
A - 13,903 kWh of energy demand for heating and hot water
B - 3.48 heat pump designed efficiency
C - new boiler efficiency of 84%
D - Gas fuel emissions of 208 gCO₂/kWh
E - Electricity fuel emissions of 277 gCO₂/kWh
Gas CO₂ = (A/C*D) = 3.44 tonnes
Electricity CO₂ = (A/B*E) = 1.11 tonnes
1-(1.11)-(3.44) = 68%
The cost of £3,999 is based on an £8,999 quote for a 3 bedroom property reduced by £5,000 due to eligibility to claim the Green Homes Grant scheme for 66% off the total cost in vouchers up to the value of £5,000.
4 times more efficient is based on a heat pump efficiency of 3.48 vs a gas boiler of 84% or 0.84. 4 x 0.84 = 3.36, which is less than 3.48.
Based on a cap 20,000 kWh heat demand and an assumed maximum efficiency of 4.4 (SCOP) will be eligible for £5,500 RHI subsidy. Additionally you could be eligible for a further £5,000 with the Green Homes Grant.
