Heat Pump Price

With government grants — plus our exclusive group-buying savings — upgrading to a cleaner, greener heating system is more affordable than you think.

What’s the Price of an Air Source Heat Pump?

In 2025, the average price of a fully installed air source heat pump system in the UK is £13,135 — including installation, upgrades, and a hot water cylinder. Most homeowners can expect to pay between £7,000 and £14,000 before any grants or discounts.

But here’s the good news:

With Switch Together, many homeowners could pay around £3,500², depending on eligibility and circumstances.

Once you factor in the Boiler Upgrade Scheme² and group discounts we offer, your upfront cost drops significantly.

¹Eligibility depends on the criteria set out by the Boiler Upgrade Scheme. Not all households will qualify.

²The £3,000 figure is an example based on a standard installation in a typical three-bedroom home, using the lowest-cost system available through our scheme in Essex, September 2024. Actual costs may be higher depending on property size, system choice, and other factors.

Why Do Heat Pump Prices Vary?

Not all homes are the same — and neither are heat pump systems. Prices can change based on:

  • Size of your home (and heat demand)
  • Type of radiators or underfloor heating
  • Your current heating system
  • Whether you need a new hot water tank
  • Insulation and Energy Performance Certificate (EPC) rating
  • Installer quality: Only MCS-certified installers can access grants
  • Installation complexity: Pipework, insulation, etc.
