Boiler Upgrade Scheme (BUS)
The Boiler Upgrade Scheme (BUS) offers government grants to help property owners install low carbon heating systems such as heat pumps. The grant is applied upfront through your installer, helping reduce the cost of switching to cleaner heating and save money on energy bills.
From 21 July 2026, grant funding is increasing for some homes.
Households that currently use heating oil may be able to receive up to £9,000 towards the cost of a heat pump. This is a 20% increase from the standard £7,500 grant and is designed to support homes particularly in rural areas. Further details will be sent to 200,000 eligible properties in England and Wales, with information on how to claim the extra funding.
