What is the Cost of an Air Source Heat Pump Installation?
Including materials and labour fees, an air source heat pump installation costs in the UK between £7,000 and £11,000. However, some larger or more complex installations can potentially cost up to £15,000.
Prices may also be higher in areas such as London and the South East, as labour fees often increase to reflect the regional cost of living.
Air source heat pumps are highly efficient systems that absorb heat from the outside air and use it to produce heat for radiators or underfloor heating. They can extract air and external heat, even at low temperatures, and although they require electricity to operate, the heat generated is constantly being renewed naturally.
Alongside ground source heat pumps, air source heat pumps are promoted in the UK as a low-carbon heating system that provides an energy efficient alternative to installing more traditional gas and electric central heating.
Are air heat pumps noisy? We're unsure whether the unit that goes outside will annoy neighbours or disturb our peace.
"Not at all, you will a sort of fan 'hum' but that’s all. Would only really recommend with underfloor manifold or you’ll need to over size radiator to allow for heat. Best to check the manufacturer's instructions of the heat pump you're looking at getting to find out the exact DB level."

There seems to be a lot of debate about whether heat pumps work in older homes. What does an old house need for one to work effectively?
"Nothing to stop you, other than it can be expensive to run.
Any company that came out to estimate for you would need to carry out quite an extensive survey of the property regarding its heat loss. If they don't carry out this survey, they are not worth dealing with.
The problem with our older housing stock is they were built during an era of cheap energy, open chimneys, and cavity walls with no insulation. They just haemorrhage the heat you have produced, I'm afraid.
In summary, it is all about the insulation levels as others here have mentioned."

Air Source Heat Pump Running Costs
Understanding the ongoing running costs and servicing costs will give you a clearer picture of what your total expenditure will be.
Heat pumps use electricity rather than gas, so your annual energy bills will depend largely on your energy tariff, the size of your property, and the insulation in your home. A well-maintained heat pump system that produces 2 to 4 times as much heat as it consumes can make a big difference in heating bills over time, particularly when replacing traditional heating systems.
Annual heat pump service costs are usually the same regardless of property size, typically costing between £100 and £200 per year when carried out by a certified engineer.
Let's take a look at some typical annual running costs based on the size of your home:
| House Size | Annual Estimated Cost |
|---|---|
| 2 bedroom semi-detached | £700-£1,000 |
| 3 bedroom semi-detached | £800–£1,200 |
| 4 bedroom detached | £1,000–£1,400 |
| 5 bedroom detached | £1,200–£1,500 |

Alternative Types of Heating Systems
When comparing your options, it is worth looking beyond installation cost alone. For many homeowners, the combination of heat pump grants and long-term energy savings can make switching a worthwhile investment, particularly when replacing oil or LPG systems.
Unlike gas boilers, air source heat pumps qualify for heat pump grants that can help cover the higher upfront cost. A gas boiler may cost less to install and have slightly lower running costs, but the £7,500 Boiler Upgrade Scheme grant effectively offsets that difference for many homeowners.
For oil and LPG households, switching to a heat pump can reduce both running costs and energy bills, while also providing more stability against fluctuating energy prices.
Below we take a look at the alternative systems, and compare their average installation costs (material and labour fees combined). However, this doesn't include running costs or maintenance costs:
| Type of system | Average supply & installation cost | Any UK government grants available? |
|---|---|---|
| Air-to-air ASHP | £2,400–£8,000+ | Yes |
| Air-to-water ASHP | £7,000–£15,000+ | Yes |
| Gas combi boiler | £1,200–£4,000 | No |
| Electric boiler | £1,700–£4,600 | No |
| Biomass boiler | £7,000–£20,000+ | Yes |

Additional Air Heat Pump Installation Costs
Once you've arranged for your installation, it's not always just the heat pump running costs you need to consider. There may be additional jobs that also need to be arranged at the same time:
- Replace a Radiator – Normally around £200 per radiator to have them removed and a new one fitted.
- Installing Central Heating – On average costing £4,250 depending on the size of property and extent of the requirements.
- Underfloor Heating – £40–£190 per m² depending on the type of system, with overall cost varying by property.
- Installing Floor Insulation – Although costs vary by material, type of flooring, and area covered, on average budget around £800.
- Roof Insulation – In 2026, the average cost of roof insulation is between £400 and £600 for a standard pitched roof.
- Cavity Wall Insulation – £1,000–£5,000 depending on property size and location, as well as accessibility.
- Plumber Costs – You may require additional plumbing work to be carried out, costing between £45 and £80 per hour, or £250–£500 per day for bigger jobs.
- Electrician Costs – An electrician is often needed to install a dedicated circuit for the heating pump, connect any controls, and update consumer units if required.
Can you use a heat pump with underfloor heating?
"Yes, a ground or air source heat pump can be used for underfloor systems, as well as hot water and radiators if required."
Things to Consider Before Installing a Heat Pump
- Space requirements – You need a suitable outdoor location for the hot water cylinder and pump unit, with enough clearance to allow sufficient airflow.
- Types of systems –
- Air-to-water: Distributes heat via your wet central heating system through conventional (though much larger) radiators or “wet” underfloor heating. These systems provide hot water.
- Air-to-air: Produces warm air, which is circulated throughout your home by fans. These systems do not provide hot water, so another heat source will be required.
- Installer Qualifications – The installation and any repairs or servicing must legally only be carried out by an F-Gas certified professional, as heat pumps contain refrigerants that are regulated by UK law.
- Backup heating – Even with air-to-water systems, it’s recommended to have a conventional heating backup for periods when the heat pump alone cannot meet all your heating needs.
- Heating performance – Heat pumps deliver heat at lower temperatures over longer periods. Radiators may not feel as hot as with a gas or oil boiler, and in very cold weather the pump may need to run continuously.
- Carbon emissions and maintenance – Air source heat pumps lower your home’s carbon footprint and require minimal ongoing maintenance.
- System efficiency and energy savings – Poorly designed or installed systems may struggle to heat your home efficiently, which can reduce potential savings. Choose an installer with proven experience and a verifiable track record.

Are air source heat pumps easier to install than ground source heat pumps?
"Yes, air source heat pump installation is much easier than ground source. Ground source pump installations cost about 2 – 5 times more than air source too."
Benefits of Installing an Air Source Heat Pump
Below are a list of benefits that are worth considering when looking at the cost of installing air source heat pumps:
- Air source heat pumps produce heat at a lower temperature than traditional boilers.
- As a result they are most energy efficient in well-insulated homes.
- Your average installation cost provides a quick return on investment.
- Making them cost-effective, especially when replacing an electric boiler or solid fuel system.
- No need to worry about flue or chimney blockages.
- No gas boiler or oil tank - reducing potential hazards.
- Reduces smoke and harmful fumes, helping to create a cleaner, healthier living environment.
- Therefore supporting environmental sustainability by reducing your carbon footprint and emissions.
UK Boiler Upgrade Schemes and Grants
In the UK, there are several government-backed schemes to help with the cost of installing an air source heat pump. These are designed to improve home energy efficiency and reduce your carbon footprint.
You may need to meet certain criteria regarding your property type and system specifications to become eligible. It's always best to check with your local council or a certified installer for further advice before proceeding with the work.
- Boiler Upgrade Scheme (BUS) — In England and Wales, homeowners can currently receive £7,500 towards the installation of air source, ground source, water source heat pumps, and biomass boilers.
- Energy Company Obligation (ECO4) — The ECO scheme helps eligible households across the UK improve energy efficiency and reduce the cost of replacing older heating systems with low-carbon alternatives. This scheme is currently scheduled to end in March 2026, although it may be extended.
- Warm Homes Local Grant — Low-income homes across England may be eligible for grants of up to £15,000 to cover energy efficiency upgrades, including heat pump installations.
- Home Energy Grants and Loans (Scotland) — Scottish homeowners may qualify for grants of £7,500–£9,000 for pump installations, with interest-free loans available to cover additional costs.
Domestic heat pump installations also currently benefit from 0% VAT until 31 March 2027 (instead of the standard 5%), helping to reduce upfront heat pump costs even further.
For a hybrid heating system, is it better to have a ground source heat pump or an air source heat pump? What would you recommend?
"This depends on the size of the heat loss for the property. Air source heat pumps cost less and can be set up on bi valent point (depending on the heat loss), so the heat pump will switch off at a set outside weather temperature and the secondary boiler will then take over the heating."
Building Regulations & Planning Permission for Heat Pump Installations
Planning Permission
In most instances, installing a heat pump at your property is classed as a permitted development and therefore no planning permission is required. However, this is providing certain conditions are followed in regards to its size and placement, noise levels, and how many units are installed.
If you live in a listed building, conservation area or a property with additional development rights put in place, planning permission guidelines may vary. For more information you can check with your local authority or a MCS-certified installer.
Flats and apartments are also often in close proximity of neighbours and nearby properties, as such the positioning of the unit and noise impact on the surrounding area are both monitored closely. Consent is also required from any freeholders or management company, as work carried out can also affect the rest of the building and its residence.
Most caveats for permitted developments relate to larger domestic properties, additional considerations need to be put in place regarding installing an air source pump connected to a flat. While technically still possible, it's less common in practice as sufficient outdoor space is required and planning permission is often much stricter.
Building Regulations
As for building regulations, a reputable company or tradesmen will know any rules and regulations that apply, and any work can often be self-certified on the assumption they are qualified to do so. These regulations cover energy efficiency and system performance (Part L), electrical safety (Part P), health and safety in regards to when a hot water cylinder is installed (Part G), and any ventilation requirements to avoid overheating.
You should always ensure you are aware of any legal requirements prior to going ahead with the installation.
Checklist: Installing an Air Source Heat Pump in the UK
Consider the following when having your heat pump installed:
- Is your heat pump installer MCS-accredited? Only MCS-accredited installers are able to sign off on pump installations that comply with the government’s schemes.
- Do they carry an F-Gas certification? Modern heat pumps can only be installed by gas-registered engineers who are F-Gas certified to ensure a safe and compliant installation.
- Have you received advise on the best system? Air-to-water systems work with radiators or floor heating and provide hot water, whereas air-to-air systems circulate warm air although require a separate hot water source.
- Can they install a back-up heating system? During the colder months, you may require a more traditional gas boiler as a back-up system, or alternatively an electrician can supply an electric storage heater.
- Have you received multiple quotes? It is highly recommended to gather at least three seperate quotes to compare pricing when having a heat pump installed, MyJobQuote can put you in touch with local tradesmen without any commitment.
- Does the quote contain an itemised breakdown? By having everything that's included confirmed in writing will avoid any awkward conversations and ensures additional jobs, such as waste removal, are clearly noted.
- Do they have positive reviews? Check their online pressence, along with the MyJobQuote profile to see genuine feedback and customer reviews from previous jobs.

FAQs
How does a heat pump save me money?
Heat pumps typically produce 2 to 4 times more heat energy than the electricity required for them to run. As an average, between 65% to 75% of the heat comes from the outside air, with the natural environment providing a renewable source or energy, while the balance is produced from electricity.
What types of heat pumps are available?
Most heat pumps use electricity to drive the pump, but there are a small number of heat pumps available which use gas. Both of which absorb energy from the air using a fan to draw through the heat pump outside, although gas pumps aren't very common for the home, they are growing in popularity within commercial and industrial installations.
Can you install air source heat pumps yourself?
No, by law your heat pump must be installed by an F-Gas certified professional. Installing one DIY or using a tradesman who isn't officially certified is not only dangerous if not done correctly, but also illegal. It can also void your warranty, as well as affecting your home insurance and any related claims.
Are heat pumps worth the cost saving/investment in a smaller property?
Depending on how small your property is, you may only have annual savings of £200 to £400 per year on your energy bills making it a slow return on investment. However, the heat pump's efficiency of having a low carbon heating system also benefits from being more environmentally friendly compared to traditional heating systems.
How long do air source heat pumps last?
A typical lifespan on average is around 15–20 years when looked after properly. This includes annual servicing by a certified engineer, keeping the outdoor unit clear of any dirt or other debris, and routinely checking the filters, refrigerant levels, and insulation. With proper maintenance they may last even longer.
What factors impact the running costs of an air source heat pump?
The cost can depend on how energy efficient your chosen system is once it's being used, along with the heat source, radiator size, your provider and energy tariff. There are also other ways to reduce your energy bills, such as ensuring your property is well-insulated throughout.
Can air source heat pumps be used for an air conditioning system?
Yes, it's possible to install a system that can provide cool air as well as heating. Essentially when on a cool setting, they work in reverse by removing internal hot air and distributing it outside. They do normally cost around an extra 5-10% compared to just having a heat pump installed, however, heat pump running costs are usually more efficient than a regular air conditioning unit.
Is an air source heat pump suitable for my home?
Most homes can accommodate an air source heat pump, but well-insulated properties with a good energy performance certificate tend to see the best results. Poorly insulated homes may need energy efficiency improvements such as solid wall insulation or radiator upgrades before installation, and an MCS certified installer will carry out a heat loss survey to assess your home beforehand.
Can I pair an air source heat pump with solar panels?
Combining solar panels with a heat pump is a really effective way to reduce running costs, as any electricity generated offsets the energy your heat pump uses. Over time, the two systems together can make a real difference to energy bills and reduce your reliance on your energy supplier.
