Common Questions About Air Source Heat Pumps Answered

As the UK moves towards more sustainable and energy-efficient heating solutions, many homeowners and businesses are exploring the benefits of Air source heat pumps. Whether you’re looking to cut down on energy bills or reduce your carbon footprint, air source heat pumps offer a smart, eco-friendly alternative to traditional gas or oil boilers.

But with any new technology, questions arise. If you’re considering making the switch, this guide will walk you through the most frequently asked questions, so you can make an informed decision with confidence.

What Exactly Is an Air Source Heat Pump?

An air source heat pump is a renewable heating system that extracts heat from the outside air, even in cold temperatures and uses it to warm your home or commercial space. It works similarly to a fridge, but in reverse. The system can provide both heating and hot water and, in some cases, cooling during the summer months.

There are two main types:

• Air-to-water systems, which heat water for radiators or underfloor heating.

• Air-to-air heat pumps, which circulate warm (or cool) air directly through the property.

How Much Does It Cost to Install One?

Installation costs vary depending on the size of the property, the type of system, and whether you’re replacing an old boiler or starting from scratch. As a general guide:

• Domestic installations typically start from £6,000 to £12,000

• Larger commercial properties may require higher investment, depending on scale and design

  
  

However, thanks to government incentives like the Boiler Upgrade Scheme (BUS), homeowners can currently receive £7,500 off the cost of a new air source heat pump, making it more affordable than ever.

Will It Work in Cold UK Weather?

Yes. One of the biggest misconceptions is that air-to-air heat pumps don’t work in colder climates. In reality, modern systems are highly efficient even when temperatures drop below freezing. They’re designed to operate effectively in the UK’s varied weather conditions, keeping your property comfortable all year round.

What Are the Main Benefits of Switching?

Switching to a sustainable heating solution like an air source heat pump offers a range of benefits:

•  Lower energy bills due to higher efficiency

•  Reduced carbon emissions, helping the environment

•  Eligibility for government grants and incentives

•  Dual functionality – heating in winter, cooling in summer

•  Increased property value and future-proofing against energy changes

  
  

It’s a long-term investment in both your comfort and your environmental impact.

Is My Property Suitable for an Air Source Heat Pump?

Most properties can accommodate an air source heat pump, but there are a few things to consider:

• Outdoor space is required for the external unit

• Good insulation helps maximise efficiency

• Underfloor heating or larger radiators may be needed for optimal performance

Our energy-efficient heating system specialists in Nottingham can carry out a full site assessment to determine suitability and recommend the best system for your needs.

Are There Any Government Grants or Incentives Available?

Absolutely. As of 2025, homeowners in England and Wales can apply for the Boiler Upgrade Scheme, which offers:

•  £7,500 off the cost of installing an air source heat pump

• No repayment or means testing

• Support for both owner-occupied and rental properties

Our team can guide you through the application process to make sure you get the maximum benefit.

How Much Maintenance Is Required?

One of the biggest advantages of renewable heating systems is their low maintenance requirements. To keep your system running efficiently:

• Book an annual service with a qualified engineer

• Keep the outdoor unit clear of leaves or debris

• Check for any system alerts or irregularities

  
  

With proper care, most air source heat pumps last 15 to 20 years, making them a reliable long-term solution.
