How Our Heat Pump Calculator Works
We’ve designed our calculator to be as simple and accurate as possible. Here’s what makes it different:
Step 1: Property Information
Tell us about your home – the type of property, number of bedrooms, and insulation level. This helps us determine the right size heat pump for your needs. A 3-bedroom semi-detached house typically needs a 9kW heat pump, while larger properties might need 12-14kW systems.
Step 2: Current Heating System
We need to know what you’re currently using – gas boiler, oil, LPG, or electric heating. This is crucial because your potential savings depend entirely on what you’re comparing against. Gas boiler users typically save £400-600 per year, while oil heating users can save over £1,000 annually.
Step 3: Additional Requirements
Heat pumps work at lower temperatures than traditional boilers, so some homes need radiator upgrades. We’ll ask about your current radiators and whether you need a new hot water cylinder. This ensures your quote is comprehensive with no hidden surprises later.
Step 4: Get Your Results
Instantly see your estimated costs broken down by equipment, installation, and any additional work. We show you the total before and after the £7,500 government grant, plus your estimated payback period.

Understanding Heat Pump Installation Costs in 2025
Heat pump costs vary significantly based on several factors. Here’s what you need to know:
Equipment Costs
The heat pump unit itself typically costs between £5,000 and £12,000 depending on the size and brand. A small 6kW unit suitable for a 2-bedroom flat might cost around £5,000, while a larger 14kW system for a 5-bedroom house could cost £9,000-12,000.
Installation Costs
Professional installation by an MCS-certified engineer typically costs £2,500-4,000. This includes connecting the outdoor unit, integrating with your existing heating system, electrical work, and commissioning.
The £7,500 Boiler Upgrade Scheme Grant
The UK government offers a £7,500 grant through the Boiler Upgrade Scheme to make heat pumps more affordable. This grant is available for homeowners and landlords in England and Wales. The installer applies for the grant on your behalf.
Running Costs Explained
With UK electricity prices around 27p per kWh, here’s what you might expect:
- Well-insulated 3-bed house: £600-800 per year
- Average 3-bed house: £800-1,100 per year
- Poorly insulated 4-bed house: £1,200-1,500 per year
Frequently Asked Questions
How much does a heat pump cost to install in the UK?
The total cost for a typical air source heat pump installation ranges from £8,000 to £18,000 before grants. After the £7,500 government grant, your out-of-pocket cost would be £500-10,500 depending on your specific requirements.
Are heat pumps cheaper to run than gas boilers?
For most homes, yes. While electricity is more expensive per kWh than gas, heat pumps are 3-4 times more efficient. A well-insulated home typically costs £600-900 per year to heat, compared to £900-1,400 for gas.
How long does it take to pay back a heat pump?
With the £7,500 grant, payback periods typically range from 4-10 years. Homes switching from oil or LPG see faster payback times (4-6 years).
Do I need to upgrade my radiators?
Not always, but it depends on your existing radiators. Heat pumps work at lower temperatures, so you may need larger radiators in some rooms. A professional survey will determine what’s needed.
What size heat pump do I need?
As a rough guide: 1-2 bedroom properties need 5-7kW, 3 bedroom homes need 8-10kW, 4 bedroom houses need 10-12kW, and 5+ bedroom properties need 12-16kW. Our calculator provides an estimate based on your specific property.
