Fueled by renewable electric energy
Answer these simple questions and find out how to upgrade your home’s efficiency today.
- Heat pumps use the tried and tested principle of a refrigerant cycle (like your fridge at home) to heat your home.
- Heat pumps are a cost-effective, renewable, low maintenance alternative to combustion system like your gas boiler.
- The boiler upgrade scheme, backed by the government, gives homeowners £7,500 off the installation cost.
- By replacing your system you could save thousands on your energy bills and will reduce your carbon footprint.
Interested in reaping these benefits of upgrading your old heating? Then stick around to find out what kind of heat pumps there are, how they work, how much they cost, and the kind of savings you can expect from a heat pump installation.
How does a heat pump work?
So, how exactly do heat pumps work? It’s often described as fridge in reverse. That isn’t far off as it uses the same principles of a refrigerant cycle.
A heat pump works by extracting what heat is outside and transferring it into your home. An air source heat pump extracts heat from the air outside, while a ground source heat pump absorbs warmth from the ground.
They have a chemical substance known as a refrigerant in them. What heat, or energy, they’ve managed to extract from the outside is transferred to the refrigerant. The heat pump then squeezes (“compresses”) the refrigerant to increase it’s temperature. Once hot enough it transfers this heat to water flowing through your home.
Heat pumps are known for their high efficiency, with efficiency ratings as high as 400%. The means for every 1 unit of energy used they produce up to 4 times more, helping you enjoy optimal heating and save on your heating bill at the same time.
Are heat pumps worth it?
Yes, heat pumps are worth it! One of the main benefits of installing a heat pump is that they offer savings on your yearly energy bills and as they are designed to last you can expect to see savings for many years to come.
If you have a 2 – 3 bedroom house and reach the high efficiencies we design at, you can break even on your investment in an ASHP in 6 – 10 years.
Air source heat pumps run on electricity, and all indicators point to gas prices rising and electricity falling. As this happens you will see even bigger savings by making the switch.
Heat pumps are also worth it because of their reduced impact on the environment. They are 3-4 times more efficient than traditional heating or cooling systems, meaning that they produce fewer carbon emissions than a gas boiler and an air conditioning unit.
The Costs
The cost of an air source heat pump will vary on the grants you are eligible for, the size of the heat pump your home requires and how much work is involved to upgrade your current heating system so that it works with an air source heat pump.
Installing an air source heat pump typically costs you between £6,000 and £10,000 after the grant.
| Household Size | Heat Pump | Estimated Cost |
|---|---|---|
| 2 bedroom | 5kW | £6,000 - £7,000 |
| 3 - 4 bedrooms | 9-12kW | £7,000 - £9,000 |
| 5+ bedrooms | 14+kW | £9,000 - £12,000 |
Grants Available
As you can see there is significant contribution required to install an air source heat pump. The good news is there are several grants available to help those wishes to make the switch.
The Boiler Upgrade Scheme gives homeowners who have never had a renewable heating system installed before £7,500 off the cost of installation.
The Energy Company Obligation (ECO4) gives opportunity to those on lower incomes to receive larger funding.
Renewable technologies like air source heat pumps and solar panels also currently have no VAT charge associated with them.

Most Asked Questions about heat pumps
Yes heat pumps work well in the UK climate. They are installed across the world in both hot and cold countries. Because of the moderate climate of the UK they perform very well in this country.
Generally, the existing pipework in a house can accommodate a heat pump installation without requiring major changes. However, we can determine whether any adjustments need to be made when we survey your home.
We recommend having a hot water cylinder installed at the same time as your air source heat pump to achieve maximum efficiency and ensure you have ample hot water when you need it
A typical install which doesn’t require too many pipework alterations will last between 2-3 days. The length of work will be discussed with you once we have designed a system for your property.
