Air source heat pumps are a smart way to heat your home. They use electricity to extract heat from the outside air. These systems offer a cleaner and greener alternative to a gas boiler. But many people ask, “How much does a heat pump cost?” or “What is the installation cost in the UK?”
In this blog, we explain everything simply. We’ll cover the air source heat pump replacement cost, running costs, maintenance, and available grants. Plus, you’ll find useful tables and tips to cut the cost.
What Is an Air Source Heat Pump?
An air source heat pump takes heat from the air outside your home. It transfers this heat inside to warm rooms and water. This type of heat pump works even in cold weather. It uses less electricity than the heat it produces.
That makes it energy efficient and better for the planet. You can install an air source heat pump instead of a gas boiler. There are also ground source heat pumps and water source heat pumps, but those are often more costly.
An air-to-water heat pump can provide hot water as well as heat your home. An air-to-air heat pump will heat your home but not provide hot water. Air source and ground source heat pumps both work well but vary in cost and installation needs.
Air Source Heat Pump Installation Cost in the UK
The biggest part of the air source heat pump cost is the installation. The price depends on the size of your home and the system you choose. Many homeowners ask about the air source heat pump installation cost or wonder how much the upfront cost of a heat pump will be.
You might also need to upgrade radiators, pipework, or insulation. These are extra costs. Here is a table to provide an approximate cost of the whole installation:
| Item | Estimated Cost (GBP) |
|---|---|
| New Air Source Heat Pump | £4,000 – £7,000 |
| Installation Labour | £2,000 – £4,000 |
| Radiator Upgrade (if needed) | £800 – £1,500 |
| Hot Water Cylinder (if needed) | £600 – £1,000 |
| Insulation Work (optional) | £500 – £2,000 |
| Total Installation Cost | £7,000 – £15,000 |
A heat pump installation is costly, but it can be reduced by the utilization of grants. Quotes must be obtained from UK-qualified heat pump installers.
There is a UK air source heat pump cost calculator which can be utilized to give an estimate of your cost depending on the size of your home and your heating requirements.
How Much Does an Air Source Heat Pump Cost to Run?
Running a heat pump depends on your electricity rate, insulation, and home size. But heat pumps are more efficient than gas boilers.
They can reduce your energy bills over time. If you’re wondering how much does an air source heat pump cost to run, the answer varies, but on average, heat pumps cost around £40 to £140 per month. Let’s look at estimated heat pump running costs:
| Home Size | Average Monthly Running Cost |
|---|---|
| 1-2 Bedroom Flat | £40 – £60 |
| 2-3 Bedroom House | £60 – £100 |
| 4+ Bedroom House | £100 – £140 |
The cost of owning a heat pump also depends on your heat pump rate. Some energy companies give lower rates to heat pump users.
You can try using a heat pump cost calculator to get a figure that is more suitable for you. This will help you better understand source heat pump running costs for your situation.
What Affects the Total Heat Pump Cost?
The cost of a heat pump varies depending on numerous factors. First, the size of the heat pump that you require affects the installation and purchase price.
Second, the condition of your home matters. Poor insulation will increase running costs. Third, your existing heating system plays a role. If you have an old system, the air source heat pump installation may need more work. That increases labour charges.
Homes that need upgrades in radiators or cylinders face extra costs. Also, older homes may require extra insulation. This adds to the installation cost in the UK.
The price also differs based on the type of heat pump, whether air-to-water or air-to-air. Ground source heat pumps are pricier as they involve digging and installation.
Are There Grants to Cut the Cost?
Yes, you can pay the zero upfront cost of installing a new heat pump with government funding. In Wales and England, the ECO4 Scheme provides grants that cover both the price of an air source heat pump plus the cost of installation.
More so, in England and Wales, the Boiler Upgrade Scheme offers £7,500 to help with the cost of installing a new air source heat pump. This makes the air source heat pump replacement cost much lower.
Scotland offers support through Home Energy Scotland Grants and Loans, where you can get up to £15,000 in support. These grants make it easier to install an air source heat pump or switch from a gas boiler to a heat pump. Always use a certified heat pump installer to qualify. Here’s a quick summary:
| Grant Scheme | Area | Support Available |
|---|---|---|
| ECO4 Scheme | England, Scotland, & Wales | Unlimited (Covers price of an air-to-water heat pump, solar panels including installation) |
| Boiler Upgrade Scheme (BUS) | England/Wales | £7,500 Grant |
| Home Energy Scotland | Scotland | £7,500 Grant + £7,500 Loan |
| Local Council Grants | UK-wide | Varies by Location |
These grants cut the cost of buying a heat pump upfront and allow more people to make the transition.
What Are the Maintenance Costs of Heat Pumps?
Heat pump maintenance costs are usually low. A yearly service is recommended to ensure the system is in peak condition. A basic check is approximately £150 per annum. In the long term, heat pump maintenance ensures the system lasts longer and operates more efficiently.
Maintenance is lower than with a gas boiler. Heat pumps also consist of fewer parts with fewer moving parts, so fewer things can go wrong. In the long term, this is cheaper in heat and in repairs. Always use trusted professionals for service checks.
Are Air Source Heat Pumps Worth It in the UK?
Yes, especially with grants. Heat pumps from the air source are more expensive initially, but you will end up saving money. They last around 20 years, and heat pumps take less energy to produce more heat.
You save money on carbon emissions and improve the energy rating of your home. If you plan to live in your home for a very long period, they are a good choice. With the right grant, you can buy and install one at a more affordable rate.
Conclusion
Installing an air source heat pump in the UK can seem costly at first. But with help from heat pump grants, the burden becomes lighter. Once installed, air source heat pump running costs are much lower than gas or oil. Use a UK air source heat pump cost calculator to find out how much you can save.
Don’t forget, the installation cost will differ based on your home and heat requirements. Always use a qualified heat pump fitter to achieve the best result. In the long run, a budget new air source heat pump can save you money, keep you warm, and save the planet.
