Current funding guidance, checked against official sources.
The figures below were reviewed on 30 July 2026. Schemes and eligibility rules can change, so Futurum confirms the official position again when preparing a live proposal.
- Boiler Upgrade Scheme guidance
- Smart Export Guarantee signposting
- Eligibility checked against official sources
- No reliance on closed legacy schemes

Boiler Upgrade Scheme
Current GOV.UK guidance lists grants of £7,500 for air source heat pumps, £7,500 for ground source heat pumps and £5,000 for eligible biomass boilers. An additional £1,500 may apply to qualifying oil or LPG heated off-gas properties until March 2027.
- The scheme is open in England and Wales
- Property, replacement-system and installer conditions apply
- Biomass support is limited to eligible rural off-gas properties
- The installer normally manages the voucher process
Smart Export Guarantee
Ofgem confirms that participating electricity suppliers pay eligible small-scale generators for low-carbon electricity exported to the grid. Rates, contract lengths and terms are set by each supplier and must be above zero.
- Applies to eligible exported renewable electricity
- Tariffs and contract terms vary by supplier
- Suitable export metering is required
- Self-consumption remains an important design factor
Closed legacy schemes
The Feed-in Tariff closed to new applicants in April 2019, the Non-Domestic RHI closed to new applications in March 2021 and the Domestic RHI closed to new applicants in March 2022. Older Futurum articles are redirected here so historic wording is not mistaken for a current offer.
- Existing accredited participants may retain scheme-specific rights
- Closed schemes are not presented as available to new projects
- Current quotations use live official guidance
- Seek scheme-specific advice for existing accredited systems
