What is Heat Pumps?
Heating systems that move heat from outside air, ground, or water into buildings. Heat pumps are highly efficient and produce significantly lower emissions than gas boilers, especially when powered by renewable electricity.
Why it matters
Replacing gas boilers with heat pumps is one of the most impactful Scope 1 reduction actions for any business with heating requirements. Government grants through the Boiler Upgrade Scheme can offset a significant portion of installation costs.
Example
A nursery school replaces its ageing gas boiler with an air-source heat pump, supported by a £7,500 Boiler Upgrade Scheme grant. Annual gas consumption of 45,000 kWh is eliminated, reducing Scope 1 emissions by 8.3 tCO₂e.
