Ready to get started?
Most heat pump calculators are based solely on the size of your home. That is fine if you home is modern, and meets modern building standards. But only 10% of homes in the UK come anything close to this.
If your home is over 15 years old you will probably have to make some upgrades to get your air source heat pump to work effectively. This is over and above the cost of the heat pump itself.
Our calculator looks at the age and construction of your home. We give you a TRUE estimation of the likely cost of your project including all government grants available.
