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).
Park home help you can get now
ECO4 and LA Flex end on 31 December 2026. The Warm Homes: Local Grant covers park homes and runs to March 2028.
- Warm Homes: Local Grant (England) — park homes included — park homes are eligible if the home has an equivalent energy rating of D–G and household income is £36,000 or less, someone gets a qualifying benefit, or the site is in one of the most deprived postcodes. It can fund park home insulation and heating in full for owner-occupiers, if the survey recommends it and your council is taking part. Apply free on GOV.UK.
- In Scotland or Wales? — the Warm Homes: Local Grant is England only. In Scotland, Warmer Homes Scotland funds insulation and heating (Home Energy Scotland, 0808 808 2282); in Wales, Nest does the same for free if you get a means-tested benefit such as Universal Credit or Pension Credit, or have a low income, and your home is rated EPC E or below, or D with certain health conditions (0808 808 2244).
- ECO4, while it lasts — ECO4 can still fund work where a local installer has capacity, but only until 31 December 2026, and the work has to be finished, not just booked. There are no new targets and no ECO5. What replaces ECO4.
- Warm Home Discount — £150 off your electricity bill for winter 2026/27. In England and Wales it is usually paid automatically if you got Universal Credit, Pension Credit, Housing Benefit or income-related ESA on 23 August 2026. Who qualifies.

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, or £9,000 for oil or LPG homes with no mains gas until 31 March 2027 | England and Wales, property owners replacing fossil fuel heating. No EPC needed since 28 April 2026 |
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 no longer requires a valid EPC: since 28 April 2026 an EPC is only needed where the property already has one (SI 2026/390), and you no longer have to install insulation first. That removes the obstacle that used to rule most park homes out, but the grant is still only a contribution towards the cost, so for lower-income park home owners the Warm Homes: Local Grant (and ECO4 until 31 December 2026) usually fits better. Ask an MCS-certified installer whether your home is eligible.
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.
