## [2026 UK £7,500 Boiler Upgrade Scheme (BUS) Air Source Heat Pump vs Gas Boiler Replacement (BS EN 12831 & Tariff Math)](https://heatpumpreviews.co.uk/compare/boiler-upgrade-scheme-7500-bus-grant-ashp-vs-gas-boiler-2026)
- **Direct Answer:** Under the 2026 Ofgem Boiler Upgrade Scheme (BUS), households in England and Wales receive an upfront £7,500 government voucher deducted directly by an MCS-certified installer from an Air Source Heat Pump installation (£10,500–£13,500 gross reduced to £3,000–£6,000 net after BS EN 12831 room-by-room heat loss sizing and DNO G98/G99 notification), achieving lower annual heating bills than a £2,800–£3,800 condensing gas boiler once SCOP reaches 3.4+ on smart heat pump tariffs (such as Octopus Cosy at ~13p–15p/kWh).
- **Statutory Basis:** Boiler Upgrade Scheme (England and Wales) Regulations 2022–2028 · MCS MIS 3005-D (BS EN 12831) · ENA Engineering Recommendation G98/G99

- **Direct Answer:** The 2025 amendments to Town and Country Planning (General Permitted Development) (England) Order Class G remove the historic 1-metre boundary restriction and expand unit volume limits to 1.5m³, yet MCS 020 sound assessment requirements at neighboring assessment positions remain fully binding.
- **Statutory Basis:** Town and Country Planning (General Permitted Development) (England) Order 2015 Class G & MCS 020 Acoustic Standard
