Start with your property
Could your home qualify?
BUS is not means tested. You do not need to receive benefits to apply.
Check Your Eligibility →- You own a property in England or Wales, including a privately rented property.
- You are replacing an eligible existing heating system, such as gas, oil, LPG or electric heating.
- The proposed system passes the installer’s suitability checks and meets scheme requirements.
Social housing, most new builds and installations already supported by public funding for the same heat pump are excluded. Hybrid systems and replacements of existing low-carbon heating do not qualify. Eligible self-build properties have separate criteria. Private tenants can enquire with their landlord’s involvement.
A system designed around your home
Comfort starts with the right design.
A heat pump moves heat from the air or ground into your home. The survey considers heat loss, radiator sizes, hot water storage, electrical supply and the space needed for equipment.
A well-designed system can use less electricity than direct electric heating. Your running costs depend on your home, energy tariff and how the system is used.
Will I need to contribute?
The grant reduces the installation cost. Your written quote will show the funding, approved work and any balance payable before you agree to proceed.
£0 contribution on standard qualifying installations. Energy Efficient You Ltd offers fully funded air source heat pump installations where the full agreed cost is covered. Your survey and written quote confirm whether your property qualifies.
Any additional works or optional upgrades carrying a charge are explained for you to review and agree before installation.
Interest-free credit may be available where applicable, subject to eligibility and finance terms.

Read about our air source heat pump offer →Your questions, answered
Before you apply
Is this a free boiler replacement grant?
BUS supports eligible low-carbon heating upgrades. The heat pump offer on this page is for replacing your current heating with a qualifying heat pump.
Do I receive the grant as cash?
No. The installer claims the voucher and deducts it from the installation price.
Do I need to receive benefits?
No. BUS is not means tested. Property ownership and installation eligibility checks still apply.
Can a landlord apply?
Yes, eligible property owners can apply for privately rented properties. Tenants should involve their landlord before progressing.
Is every eligible heat pump installation free?
No. Eligibility for BUS and eligibility for our fully funded offer are separate checks. £0 contribution applies where the full agreed cost of a standard qualifying installation is covered. Your written quote confirms this.
Can I still apply if I have received insulation funding?
Previous support for insulation does not automatically prevent a BUS application. We check the grant history and current scheme rules for your property.
Will a heat pump lower my bills?
Savings vary with the heating system being replaced, property insulation, system design, energy tariff and use. Ask for an estimate tailored to your home.
