The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. This means if your park home is in a lower council tax band (A–D) or you receive certain benefits, you can apply for insulation upgrades. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. Homeowners must use an MCS-certified installer to claim the grant; the scheme does not cover DIY or non-certified work.
The ECO4 scheme covers park homes with specific insulation measures
ECO4 (Energy Company Obligation) applies to park homes, but only for measures listed in the scheme’s “Park Home Measures” appendix: underfloor insulation, room-in-roof insulation, and draught-proofing. ECO4 does not fund boiler replacements or heat pumps for park homes unless the home has a standard brick-and-block wall construction, which is rare for park homes (Ofgem ECO4 Guidance: Delivery, 2026, Section 6.3). Eligibility requires the homeowner to receive a means-tested benefit or live in a low-income area, defined as Index of Multiple Deprivation decile 1–3.
The Boiler Upgrade Scheme does not cover park homes
The Boiler Upgrade Scheme (BUS) is limited to homes with a solid wall, cavity wall, or timber frame. Park homes with metal or timber cladding are explicitly excluded from the scheme (DESNZ Boiler Upgrade Scheme: Eligibility Criteria, updated January 2026). Park homeowners seeking heat pumps must explore local authority grants or the Home Energy Scotland scheme instead, if they live in Scotland.
Quick numbers grant amounts and savings for park home insulation
| Measure | Typical grant (GBIS/ECO4) | Annual saving (kWh) | Annual cost saving (£) | Source |
|---|---|---|---|---|
| Underfloor insulation | £800–£1,200 | 1,500–2,000 kWh | £150–£200 | EST Insulation Savings Calculator, 2026 |
| Room-in-roof insulation | £1,000–£1,500 | 2,000–2,500 kWh | £200–£250 | EST Insulation Savings Calculator, 2026 |
| Draught-proofing | £200–£400 | 500–800 kWh | £50–£80 | Energy Saving Trust Draught-Proofing, 2026 |
| Loft insulation (top-up) | £300–£600 | 1,000–1,500 kWh | £100–£150 | EST Loft Insulation, 2026 |
Park homes do qualify for the Home Upgrade Grant in England
The Home Upgrade Grant (HUG2) specifically targets off-gas-grid homes with low EPC ratings. Most park homes use LPG or electric heating, so they qualify for this scheme. HUG2 covers insulation, heat pumps, and solar PV for park homes, with grants up to £15,000 per household (DESNZ Home Upgrade Grant Phase 2: Guidance, 2026). Eligibility is based on the local authority’s designated low-income areas. Homeowners must apply through their council, not directly to the scheme.
The direct answer park homes qualify for insulation grants but not boiler grants
The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. The key distinction is that park homes lack the standard wall construction required for BUS heat pump funding. However, their poor insulation levels make them a priority for insulation grants (DESNZ Energy Company Obligation: Park Homes, 2026 and Ofgem BUS Eligibility Check, 2026). Homeowners should always check whether their park home is classified as a “mobile home” under the Caravan Sites Act 1968, as this affects EPC requirements and grant eligibility.
How to verify an installer for park home energy grants
All grant-funded work must be carried out by an installer registered with MCS (Microgeneration Certification Scheme) for insulation and heating measures. For electrical work, such as heat pump installation, the installer must also be registered with NICEIC or NAPIT. Park home owners should check the MCS register at mcscertified.com to confirm the installer holds a valid “Insulation” or “Heat Pump” scope (MCS Find an Installer, accessed 2026 and TrustMark Park Home Installer Standards, 2026). Installers must also hold Gas Safe Register certification if the work involves LPG or gas connections, which is common in older park homes.
