Park Home Insulation Grants: How Mobile Home Owners Can Qualify

A park home insulation grant can make a transformative difference to your mobile home’s warmth and energy costs. Park homes and mobile homes are among the least energy-efficient dwellings in the UK, with thin walls, minimal floor insulation, and poor roof performance. Yet many park home residents do not realise they can access the same government-funded energy schemes as traditional homeowners. This guide explains how to qualify for free external wall cladding, floor insulation, and roof insulation through ECO4 and the Warm Homes Local Grant, with typical savings of 400 to 800 per year.

Can Park Home Owners Get Insulation Grants?

Yes, park home and mobile home owners in the UK can qualify for free insulation grants through the ECO4 scheme, the Great British Insulation Scheme (GBIS) and devolved nation programmes. Park homes are often poorly insulated and expensive to heat, making them a priority for government-funded energy efficiency improvements. Eligible measures include external wall wrap insulation, underfloor insulation and draught-proofing.

To qualify, you typically need to own your park home (not the land it sits on), receive a qualifying benefit such as Universal Credit or Pension Credit, and have a home with poor energy performance. The ECO Flex route also allows local councils to refer park home residents based on low income or vulnerability, even without benefits.

Why Park Homes Need Special Insulation

Park homes (also called mobile homes, residential park homes, or static caravans used as permanent residences) face unique energy challenges compared to brick-built properties.

• Thin walls: Most park homes have walls just 50-75mm thick with minimal or no insulation, compared to 300mm+ in modern brick-built homes
• Raised floors: The gap between the floor and ground allows cold air to circulate underneath, causing significant heat loss
• Lightweight roofs: Park home roofs are typically thin metal or lightweight panels with poor thermal performance
• Single glazing: Many older park homes retain single-glazed windows
• Air leakage: Joints between panels, around windows, and at the floor-wall junction are common sources of draughts

As a result, park home residents can pay 50-100% more per square metre on heating compared to residents of insulated brick-built homes. Annual energy bills of 2,000 to 3,000 are common for a two-bedroom park home that would cost 1,200 to 1,500 to heat if it were a standard semi-detached house.

Park Home Insulation Grant Options in 2026

Park home owners can access several grant schemes for insulation improvements. Here are the main options.

ECO4 for Park Homes

The Energy Company Obligation (ECO4) explicitly includes park homes and mobile homes. If you live permanently in a park home and receive a qualifying benefit, you can access free insulation through your energy supplier.

Qualifying benefits include Universal Credit, Pension Credit, Income Support, Income-based JSA, Income-related ESA, Child Tax Credit, Working Tax Credit, PIP, DLA, Attendance Allowance, and Carer’s Allowance.

Warm Homes Local Grant for Park Homes

Park home residents in England can apply to their local council for the Warm Homes Local Grant. The scheme provides up to 15,000 for insulation, which is often sufficient to cover external cladding, floor insulation, and roof insulation for a park home. Eligibility requires a household income below 36,000 or receipt of a qualifying benefit.

Devolved Nation Schemes

Park home residents in Scotland can access grants through Home Energy Scotland (0808 808 2282) or Warmer Homes Scotland. Welsh residents can apply through the Nest scheme (0808 808 2244). Northern Ireland residents can contact the Affordable Warmth scheme through their local council.

What Insulation Measures Are Available for Park Homes?

Park home insulation involves specialised techniques different from those used in traditional houses. Here are the main measures and their typical costs and savings.

A comprehensive package including external cladding, floor insulation, and roof insulation could save 400 to 800 per year and has a combined value of 11,000 to 22,000. Under the right grant scheme, this entire package can be funded at no cost to the resident.

External Wall Cladding for Park Homes

External wall cladding is the single most impactful insulation measure for a park home. The process involves the following.

• A timber or metal framework is fixed to the exterior walls of the park home
• Rigid insulation boards (typically 50-100mm thick) are fitted within the framework
• A weatherproof outer skin is applied, usually PVCu cladding or composite panels
• All joints, corners, and edges are sealed to prevent air infiltration
• Windows and doors are trimmed to accommodate the additional thickness

The result is a dramatic improvement in thermal performance. Wall U-values can be reduced from approximately 2.0 W/m2K (uninsulated park home wall) to 0.3-0.5 W/m2K, which is comparable to a modern brick-built wall. The external cladding also provides a fresh, updated appearance and protects the original wall structure from weather damage.

Installation typically takes three to five days for a standard two-bedroom park home. You can remain in the home during the work, though there may be some noise and limited access to certain areas on specific days.

Floor and Roof Insulation for Park Homes

Floor Insulation

Park home floor insulation is fitted underneath the home, between the chassis and the floor deck. The process involves the following.

• Accessing the underside of the home (park homes are typically raised on supports)
• Fitting rigid insulation boards or spray foam between the floor joists
• Adding a vapour barrier to prevent moisture issues
• Sealing any gaps around pipes, cables, and the perimeter

This measure eliminates the cold draught from beneath the home and can make floors noticeably warmer within hours of installation.

Roof Insulation

An over-roof system involves fitting a new insulated roof structure over the existing park home roof. This typically includes the following.

• A lightweight timber frame built over the existing roof
• Insulation boards fitted within the frame
• A waterproof membrane and new roofing sheets on top
• Improved ventilation to prevent condensation

The over-roof system also addresses a common park home problem: flat or low-pitch roofs that are prone to leaks. The new structure adds a better pitch for water runoff and provides decades of weather protection.

How to Apply for a Park Home Insulation Grant

The application process is similar to that for traditional homes but with some park-home-specific considerations.

• Step 1: Confirm you own your park home (site owner consent may also be needed for external works)
• Step 2: Gather proof of benefits or income level
• Step 3: Contact your energy supplier for ECO4, or your local council for the Warm Homes Local Grant
• Step 4: A surveyor will visit to assess the property and recommend suitable measures
• Step 5: If approved, an installer experienced with park homes will carry out the work

It is important to use installers who have specific experience with park homes. The construction methods and materials are very different from traditional houses, and using an inexperienced installer can lead to problems with moisture, structural integrity, and warranty compliance.

Site Owner Consent and Planning Issues

One complication specific to park homes is the relationship with the site owner. Even though you own the park home itself, the land it sits on is typically owned by the site operator. This can create issues with external insulation work.

• Site owner consent: Most site agreements require the site owner’s permission for external modifications. External cladding changes the appearance and dimensions of the home, so consent is usually needed
• Planning permission: In most cases, park home insulation falls under permitted development and does not require planning permission. However, if the home is on a site within a conservation area or Area of Outstanding Natural Beauty, check with your local planning authority
• Site rules: Some sites have rules about the appearance of homes, including colour schemes and materials. Discuss any proposed cladding with the site owner before proceeding

Most site owners are supportive of insulation improvements because they enhance the property and the overall site. If you encounter resistance, the grant scheme administrator can sometimes help negotiate with the site owner.

Frequently Asked Questions

Do I own my park home or rent it?

If you purchased the park home (even if you pay a pitch fee to the site owner for the land), you are the owner of the home itself. This is the most common arrangement on residential park home sites. If you rent the home from the site owner, the site owner is responsible for improvements. Most grant schemes require you to be the owner of the home to apply directly.

Will park home insulation affect the resale value?

Yes, positively. Insulated park homes command higher resale prices because buyers value lower energy bills, improved comfort, and the visual upgrade from external cladding. A well-insulated park home can sell for 5,000 to 15,000 more than an equivalent uninsulated home on the same site.

Can I get a heat pump for a park home?

Air source heat pumps can work well with park homes, but only if the home is properly insulated first. A heat pump installed in an uninsulated park home would struggle to maintain comfortable temperatures. The recommended approach is to insulate the walls, floor, and roof first, then consider a heat pump as a second phase. Some grant schemes will fund both measures as a package.

How long does park home external cladding last?

Quality PVCu or composite cladding systems have an expected lifespan of 25 to 40 years. The insulation within the cladding does not degrade over time, so the thermal benefits are permanent. Most systems come with a manufacturer warranty of 10 to 25 years, and some grant-funded installations include extended warranties as part of the quality assurance process.
