Do I need new radiators or underfloor heating?

Not always. Heat pumps work best at lower flow temperatures, so larger or more efficient radiators can improve comfort and running costs. We check every room during your survey and tell you exactly what, if anything, should be upgraded.

Do heat pumps work in very cold weather?

Yes. Modern systems are designed to work efficiently below freezing. We size your system to the local climate and set up controls so your home stays comfortable in cold snaps.

Will a heat pump heat my hot water?

Yes. Both air source and ground source systems provide space heating and hot water. Most homes will need a compatible cylinder, which we specify and include in your quote.

Do I need to improve insulation first?

There is no mandatory insulation requirement for the grant anymore, but good insulation lowers your running costs. During your survey we will advise on any easy wins such as loft insulation or draught proofing.

Is planning permission required and how noisy are they?

Most heat pump installs are permitted development if they meet siting and noise rules. We follow the MCS acoustic standard when choosing a location for the outdoor unit. Modern systems run quietly and we position them to minimise sound for you and your neighbours.

How long does installation take?

Air source installs typically take 1 to 5 days depending on the scope of radiator and cylinder work. Ground source projects usually take 1 to 2 weeks including groundworks.

What is the lifespan and what maintenance is needed?

An air source heat pump typically lasts 15 years plus, a ground source heat pump can last 20 years or more, with ground loops lasting much longer. Annual servicing keeps performance high and protects your warranty.

Running costs and efficiency

Both systems can outperform a boiler on seasonal efficiency when designed well. Ground source usually has the edge because ground temperatures are stable. Your insulation levels, radiator outputs and flow temperature will determine actual running costs. We model this for your property during the survey and include a like for like comparison in your quote.

Air Source Heat Pump Costs in 2026

If you are considering switching to an air source heat pump, cost is usually the first question homeowners ask. While heat pumps are not the cheapest heating system to install, they can offer lower running costs, reduced carbon emissions, and long-term savings when designed and installed correctly.

In this guide, we explain how much an air source heat pump typically costs in 2026, what affects the final price, and how government grants can significantly reduce the upfront investment.

Average Air Source Heat Pump Costs in the UK

In 2026, the typical cost of a fully installed air source heat pump is usually between £10,000 and £14,000 before any grants.

This price normally includes:

The heat pump unit
Hot water cylinder if required
System design and heat loss calculations
Installation and commissioning
Removal of the existing boiler if needed

Be cautious of quotes that appear much lower. Heat pumps require careful design and sizing, and cutting corners can lead to poor efficiency, higher running costs, and ongoing issues.

How the Boiler Upgrade Scheme Reduces the Cost

Most homeowners can apply for the Boiler Upgrade Scheme (BUS), which provides a £7,500 grant towards the cost of an air source heat pump.

This means many installations end up costing £3,000 to £6,000 after the grant is applied. Check to see if you are legible on the Government website here: Boiler Upgrade Scheme

To qualify, your property must:

Replace an existing fossil fuel heating system
Meet basic insulation standards
Use an MCS-certified installer (like Beatson Plumbing)

What Affects the Final Cost of a Heat Pump?

No two homes are the same, and several factors influence the final price.

Property Size and Heat Demand

Larger homes require higher output systems, which increases equipment and installation costs.

Insulation Levels

Well-insulated homes perform best with heat pumps. If insulation upgrades are needed, this can add to the overall cost but significantly improve efficiency.

Radiators or Underfloor Heating

Heat pumps work best with larger radiators or underfloor heating. Some properties need radiator upgrades to ensure the system runs efficiently.

Hot Water System

Most heat pumps require a hot water cylinder. Older or unsuitable cylinders may need replacing.

Electrical Supply

Occasionally, minor electrical upgrades are required to support the system safely.

Are Heat Pumps Cheaper to Run Than Gas Boilers?

When installed correctly, air source heat pumps are highly efficient, typically producing three to four units of heat for every unit of electricity used.

This can result in:

Lower running costs compared to older gas boilers
Greater savings especially when paired with solar panels
More predictable energy use over time

Savings depend on insulation, system design, and how the heating is used day to day.

Why Installation Quality Matters More Than Price

The performance of an air source heat pump depends far more on correct design and installation than on the unit itself. A properly designed system delivers consistent indoor temperatures, keeps running costs as low as possible, and helps the system last longer with fewer issues over time. Choosing an MCS-certified installer is also essential, as this protects your eligibility for government grants and ensures the installation meets recognised industry standards, giving you confidence that the system will perform as intended.

Frequently Asked Questions

How long does it take to install a heat pump?
Most installations take between two and five days, depending on the property and system complexity.

Do I need new radiators?
Not always, but some homes benefit from upgraded radiators to improve efficiency.

Are heat pumps noisy?
Modern systems are very quiet and meet strict noise regulations.

How long do air source heat pumps last?
With proper maintenance, most systems last 15 to 20 years.
