Air source heat pump installation guide

Thinking of installing an air source heat pump but unsure how long it takes, what happens or what to expect?

Don't worry our guide will provide you with all the information you need.

What is an air source heat pump?

An air source heat pump is a low carbon heating system that extracts heat from the outdoor air and distributes it throughout your home using radiators or underfloor heating. A heat pump that runs on electricity generated from renewable energy is a sustainable and potentially cost-effective heating solution. If you invest in a heat pump you can rely less on fossil fuels and make a positive impact on both your wallet and the environment.

How long does it take to install a heat pump?

Installation times for a heat pump can vary based on the type of heat pump you choose to install. On average, the installation typically spans between 2 to 5 days.

In some situations a solid base or drainage may need to be provided before the heat pump is ready to install. Don't worry, this will have all been discussed and arranged beforehand during the design process.

How much does an air source heat pump installation cost?

The cost of air source heat pump installations can vary depending on your chosen system. Additionally, the available government grant schemes differ based on your location within Great Britain. Here's a breakdown of the potential costs:

England and Wales

  • The Boiler Upgrade Scheme (BUS) offers a £7,500 grant, which can significantly reduce installation costs
  • We're offering new customers £750 off a heat pump with our spring discount
  • As a result, the installation cost of a heat pump in this region can range between £4,500 and £10,000


  • Home Energy Scotland provides grants of £7,500 for air source heat pump installation, and this increases to £9,000 for people in remote areas who qualify for the rural uplift
  • We're offering new customers £750 off a heat pump with our spring discount
  • As a result, the cost of installing a heat pump in Scotland typically falls within the range of £4,000 and £10,000

It's important to consider that the total installation costs may increase if additional energy efficiency improvements are needed for your home. For instance, upgrading radiators or adding insulation could increase expenses. In most cases, existing pipework and electrics can be used, but if this needs replacing, it can further add to the overall cost.

How to choose the right heat pump installer

Choosing the right installer is the most important decision to make when getting a heat pump, as it's crucial for getting the design and installation done correctly. Here are three things to look out for:


Choose an installer who is accredited by reputable organisations such as the Microgeneration Certification scheme (MCS). This accreditation ensures that the installer has undergone installer training and adheres to industry standards.

Experience and expertise

Look for installers with a proven track record and extensive experience in installing air source heat pumps for a range of different homes. Ask your potential installer lots of questions, any experienced and competent installer will be able to answer them with ease.


Read customer reviews, ask for references and check the installer's portfolio. Feedback from other customers can give you a valuable insight into the installer's professionalism and customer service.
