Government-Backed Funding
Grants for home energy improvements help eligible homeowners access government funding for insulation, heating systems and renewable energy upgrades. LAMTANS Engineering provides support for ECO4, the Boiler Upgrade Scheme (BUS) and the upcoming Warm Homes Plan — helping you check eligibility and apply for funding across Manchester and the UK.
Three Schemes
There are currently three main government grants available for home energy improvements in the UK — and each serves a different purpose. ECO4 covers insulation and heating upgrades for low-income households. The BUS Scheme supports heat pump installations for all homeowners. The Warm Homes Plan is the new flagship programme replacing ECO4 from 2026.
You don't need to navigate this alone. We check your eligibility across every scheme for you — free, with no obligation.
Side by Side
The UK government offers different home energy grants depending on your household type and property needs. ECO4 is aimed at low-income households and can fully fund eligible insulation and heating upgrades. The BUS Scheme is available to all homeowners and provides support towards heat pump installations. The Warm Homes Plan is the upcoming national programme designed to replace ECO4 and expand funding for energy-efficient home improvements.
| Grant Scheme | Best For | What It Covers | Funding |
|---|---|---|---|
| ECO4 | Low-income households | Insulation, heating, solar (some cases) | Fully funded measures possible if eligible — value varies by property; some measures partial with a possible top-up |
| BUS Scheme | All homeowners (England & Wales) | Heat pumps | £7,500 (£9,000 off-gas tier, 21 Jul 2026 – 31 Mar 2027) |
| Warm Homes Plan | Low-income and fuel-poor homes (expected broader) | Insulation, heating, renewables (expected) | Household amounts TBC — £15bn national programme |
