Park home owners can access several government-backed grants in 2026. The main routes are ECO4 and the Warm Homes: Local Grant, which can fund free insulation designed for park homes (external wall cladding, floor and roof insulation), heating and boiler upgrades, and in some cases solar panels. Park homes are exempt from the standard EPC rules that apply to bricks-and-mortar houses, so ECO4 uses a park-home-specific assessment instead — meaning the lack of an EPC does not block your application. Eligibility is usually based on receiving a qualifying benefit, your council's ECO4 Flex low-income route (typically household income under £31,000), or the Warm Homes: Local Grant income route (£36,000 or less in England).
Grants Available for Park Homes at a Glance
Park homes (also called residential mobile homes) are among the hardest properties in the UK to heat. Their lightweight, single-skin construction loses heat fast, and residents often face very high energy bills. Several schemes recognise this and specifically fund park home improvements:
| Scheme | What It Can Fund | Main Eligibility |
|---|---|---|
| ECO4 | External wall cladding, floor & roof insulation, heating upgrades, first-time central heating, heat pumps | Qualifying benefit, or council ECO4 Flex referral |
| Warm Homes: Local Grant | Insulation, low-carbon heating, solar, smart controls | England, privately owned, EPC D–G, income £36,000 or less |
| Boiler Upgrade Scheme | £7,500 toward a heat pump | Requires a valid EPC (most park homes don't have one) |
The rest of this guide breaks down each measure — insulation, cladding, heating and solar — and explains exactly who qualifies.
Insulation Grants for Park Homes
Insulation is the single biggest win for a park home, and it's where most grant funding goes. Because park homes have no cavity walls and no traditional loft, standard house insulation doesn't apply — instead, ECO4 funds systems engineered for lightweight construction:
- External wall cladding — rigid insulation boards fixed to the outside and finished with weather-resistant cladding
- Floor insulation — insulation fitted beneath the suspended floor to stop heat escaping into the airflow underneath
- Roof insulation — an over-roof system or insulation added above the existing ceiling
Our dedicated guide covers the products, the process and the savings in detail: read Park Home Insulation Grants for the full breakdown. You can also see all UK insulation schemes on our free insulation grants page.
External Wall & Cladding Grants
External wall insulation with cladding is usually the most impactful measure for a park home. Rigid insulation boards are fixed to the outside of the existing walls and covered with durable PVC or composite cladding, which also smartens up the exterior and adds weather protection. Under ECO4, this is treated as an eligible measure for park homes and is fully funded for qualifying households.
Good to know: There are roughly 85,000 park homes in England, and most were built before modern insulation standards. If your park home predates 2005, it is very likely to qualify for insulation improvements once your eligibility is confirmed.
Heating & Boiler Grants for Park Homes
ECO4 doesn't only fund insulation — it can also fund heating. For park homes this may include:
- Replacing a broken or inefficient boiler as part of a wider upgrade
- First-time central heating where a park home relies on expensive electric or bottled-gas heating
- An air source heat pump where the property is suitable
Heating measures under ECO4 are usually installed alongside insulation, because the scheme funds packages that improve the whole home's efficiency rather than single measures in isolation. See our free boiler replacement guide for how boiler funding works.
A note on the Boiler Upgrade Scheme: the £7,500 Boiler Upgrade Scheme heat pump grant requires a valid EPC. (A 2025 rule change removed the old condition that the EPC be free of outstanding loft or cavity wall insulation recommendations, so you no longer have to install insulation first to qualify — but a valid EPC is still needed.) Because most park homes don't have (or need) a standard EPC, the Boiler Upgrade Scheme is usually not the right route for a park home — ECO4 and the Warm Homes: Local Grant fit better.
Solar Panels for Park Homes
Solar is possible on some park homes, but it comes with caveats. Park home roofs are lightweight, so a structural check is essential before any panels are fitted, and not every roof is suitable. Where solar is viable, the main funding routes are the Warm Homes: Local Grant (which can include solar and smart controls alongside insulation and heating) and, occasionally, ECO4 as a secondary measure. ECO4 prioritises insulation and heating, so solar alone is rarely the first thing funded. For general solar funding, see our solar panel grants guide.
How ECO4 Works for Park Homes Without an EPC
This is where a lot of confusion sits. Park (mobile) homes are exempt from the Energy Performance Certificate rules that apply when you sell or rent a normal house, so most park homes simply don't have an EPC. For a bricks-and-mortar home, ECO4 relies heavily on the EPC band — but for park homes, Ofgem's ECO4 rules use a separate park-home assessment method instead of a standard EPC.
In practice, that means:
- Not having an EPC does not disqualify your park home
- A specialist assessor evaluates the park home using the park-home methodology set out in the ECO4 guidance
- The installer arranges this assessment as part of your application — you don't need to organise an EPC yourself
See our ECO4 eligibility guide for how the scheme assesses homes generally.
Who Qualifies for Park Home Grants?
You're likely to qualify through one of these routes:
- A qualifying benefit — for example Pension Credit, Universal Credit, Income Support, income-related ESA, income-based JSA or Housing Benefit (this is the main ECO4 route)
- ECO4 Flex (LA Flex) — your council can refer low-income or vulnerable households who don't receive a qualifying benefit, commonly where gross household income is under £31,000. See our ECO4 Flex guide.
- Warm Homes: Local Grant — for privately owned homes in England with an EPC of D–G and household income of £36,000 or less (councils can flex this for certain postcodes or benefits)
Your park home must also be your permanent, main residence — holiday homes and seasonal-use caravans are not eligible.
Site Owner Permission
If you own your park home but rent the pitch, you'll typically need the site owner's permission for external work such as wall cladding or an over-roof system. Most site owners agree, because insulation improves the look and value of homes on their site. Your installer will usually handle the consent process, but it's worth checking your pitch agreement first.
