Free Park Home Insulation Grant 2026

Park homes qualify for free insulation through ECO4 and GBIS. External wall cladding, floor insulation, and roof insulation — designed for the unique challenges of park home construction.

Free Insulation for Park Homes

Park homes (also known as mobile homes or residential park homes) are some of the hardest homes to heat in the UK. Their lightweight construction means heat escapes rapidly through thin walls, floors, and roofs. The good news: ECO4 and GBIS now cover park homes, providing free insulation specifically designed for these structures.

Insulation TypeWhat It DoesTypical Savings
External wall claddingRigid insulation boards + weather-resistant cladding fitted to outside walls£200-£400/year
Floor insulationInsulation fitted beneath the park home's suspended floor£100-£200/year
Roof insulationOver-roof system or insulation above existing ceiling£100-£200/year

Why Park Homes Need Specialist Insulation

Park homes are fundamentally different from brick-built houses. Standard insulation methods don't work. Here are the unique challenges:

  • Single-skin walls — park homes have thin walls with no cavity, so cavity wall insulation is impossible
  • Suspended floors — the floor sits above the ground on a chassis, with cold air circulating underneath
  • Lightweight roofs — minimal insulation in the original construction, often just a thin layer
  • Thermal bridging — the metal chassis and frame conduct cold into the home
  • Condensation risk — poor insulation causes warm air to meet cold surfaces, creating damp and mould
  • Structural weight limits — insulation must be lightweight to avoid overloading the structure

ECO4 installers who specialise in park homes use approved insulation systems engineered specifically for lightweight timber and metal construction. These are not the same products used in brick-built houses.

External Wall Cladding

External wall cladding is the most impactful insulation measure for park homes. The process involves:

  • Fitting rigid insulation boards to the outside of the existing walls
  • Covering the insulation with weather-resistant cladding (typically PVC or composite)
  • Sealing all joints to prevent draughts and moisture ingress
  • Improving the appearance of the park home (many residents say it looks brand new)

External cladding typically takes 3-5 days to install and can reduce wall heat loss by up to 50%. It also provides an additional layer of weather protection.

Floor Insulation

Park home floors lose significant heat because they're suspended above the ground. Floor insulation involves fitting rigid insulation boards or spray foam to the underside of the floor. Skirting around the base of the park home is also improved to reduce cold air circulation underneath.

Important: There are approximately 85,000 park homes in England alone, and most were built before modern insulation standards. If your park home was built before 2005, it almost certainly qualifies for insulation improvements under ECO4.

Roof Insulation

Park home roofs are often the weakest point for heat loss. Two main approaches are used:

  • Over-roof system — a new insulated roof built over the existing one, creating an air gap and adding significant insulation
  • Internal ceiling insulation — insulation added above the existing ceiling (reduces room height slightly)

An over-roof system is generally preferred because it also provides better waterproofing and doesn't reduce internal space.

Who Qualifies for Free Park Home Insulation?

You qualify for free park home insulation through ECO4 if you receive a qualifying benefit:

  • Pension Credit (Guarantee or Savings Credit)
  • Universal Credit
  • Income Support
  • Housing Benefit
  • Income-based JSA or income-related ESA
  • Child Tax Credit (income below £16,480)
  • Working Tax Credit (income below £16,480)

Through GBIS, park homes in council tax bands A-D can qualify for free insulation with no benefits requirement.

Site Owner Permission

If you own your park home but rent the pitch, you will typically need the site owner's permission for external work such as wall cladding and over-roof systems. Most site owners are happy to agree because insulation improves the appearance and value of homes on their site. The ECO4 installer will handle the consent process for you.

Park Home Insulation — Common Questions

Yes. Park homes (also called mobile homes or residential caravans) are eligible for insulation under ECO4. You need to receive a qualifying benefit such as Pension Credit, Universal Credit, Income Support, or Housing Benefit, and your park home must be your permanent residence. ECO4 can fund external wall cladding, floor insulation, and roof insulation for park homes.
Park homes can receive several types of insulation through ECO4: external wall cladding (rigid insulation boards fitted to the outside and finished with weather-resistant cladding), floor insulation (fitted beneath the park home to reduce heat loss through the suspended floor), and roof insulation (added above the existing ceiling or as an over-roof system). These measures are specifically designed for the lightweight construction of park homes.
If you own your park home but rent the pitch, you typically need the site owner's permission for external alterations such as wall cladding or an over-roof system. Most site owners agree because insulation improves the appearance and value of homes on their site. The ECO4 installer will usually handle the consent process. Internal measures may not require site owner consent, but it's best to check your pitch agreement.
Yes. Park homes in council tax bands A-D can qualify for free insulation through the Great British Insulation Scheme (GBIS), which has no benefits requirement. However, GBIS typically covers loft and cavity wall insulation — since park homes don't have traditional lofts or cavity walls, ECO4 is usually the more relevant scheme because it specifically funds external cladding and floor insulation designed for park home construction.
Park homes are notoriously expensive to heat due to their lightweight construction and poor insulation. A full insulation package (external cladding, floor, and roof insulation) can reduce heating costs by £400-£800 per year depending on the size of your park home and your heating system. Many park home residents report their homes becoming warm for the first time after insulation is installed.
Park homes have several unique insulation challenges: they have thin, single-skin walls with no cavity; floors are suspended above the ground, losing heat to air movement beneath; roofs are often lightweight with minimal insulation; and the chassis and frame can create thermal bridges. Standard house insulation methods don't work — park homes need specialist products designed for their lightweight timber and metal construction. ECO4 installers who work on park homes use approved systems specifically engineered for these structures.
