Air Source Heat Pump Cost FAQs
The average cost of an air source heat pump in the UK ranges from £10,000 to £14,000, including installation. However, with Adlår’s direct-to-consumer model and the £7,500 BUS grant, your total cost could be significantly lower.
Our calculator provides a personalised estimate based on your property size, insulation, and heating demand. While it’s a strong starting point, a free home survey is the best way to confirm final pricing and savings potential.
A sizing calculator estimates the heating output (in kW) your home requires. This helps ensure the system is neither too large (wasting energy) nor too small (underperforming). Our calculator includes sizing analysis to ensure your Adlår system is just right.
Running costs depend on:
- Electricity prices
- System efficiency
- Your heating habits
On average, an Adlår heat pump could cost £500–£900 per year to run, compared to £1,500+ for oil or electric systems — a potential saving of £1,000+ per year.
The BUS grant provides £7,500 off the installation cost of an air source heat pump for eligible homes. Adlår handles the entire application on your behalf — reducing hassle and speeding up approval.
