Frequently Asked Questions
How much does the Boiler Upgrade Scheme save?
The BUS provides £7,500 towards air and ground source heat pumps. Your installer applies on your behalf and deducts it from your quote.
Do I need to improve insulation first?
Heat pumps work best in well-insulated homes. An EPC assessment will identify if upgrades are needed. The Warm Homes Plan may cover insulation costs.
Are heat pumps noisy?
Modern air source heat pumps produce 40-50 dB at 1 metre — similar to a fridge. Planning rules require units be placed at least 1m from boundaries.
