Improve the comfort and energy efficiency of your park home with professionally installed insulation solutions. Our retrofit services help reduce heat loss, lower energy bills and create a warmer, more comfortable living environment all year round.
Park homes are notoriously difficult to heat — thin walls, single glazing and limited insulation are common. A specialist insulation retrofit can transform energy efficiency, reducing bills and improving comfort.
Park homes have lightweight steel or timber frames with thin insulation — typically just 40–60mm. Standard insulation methods designed for brick homes do not apply.
A poorly insulated park home can cost in the region of £1,500–£3,000 per year to heat — far more than a modern brick home. The right insulation can typically reduce heating costs by around 40–60%, depending on the property, the measures installed and how the home is used.
Specialist insulation systems can be retrofitted without damaging the park home structure. Breathable materials are used to prevent condensation.
Insulation boards (40–100mm) fixed to the external walls and finished with render or cladding. Generally the most effective method — and it refreshes the external appearance. May require park owner approval and, on some sites, local authority consent.
Insulated plasterboard fixed to the internal walls. Less disruptive to the external appearance, but reduces floor space by around 50–80mm per wall. Suitable for parks where external changes are restricted.
Insulation installed beneath the park home to reduce heat loss through the floor. Requires access from below — in some cases the home needs to be lifted to create it.
Insulation added to the roof void or the external roof surface — either a warm roof system (insulation above the roof deck) or a cold roof system (insulation between the joists).
ECO4 funding may be available for park home insulation in the UK, subject to eligibility checks, your EPC rating and government scheme approval. Park homes typically suffer from high heat loss and poor insulation performance — exactly the kind of property the scheme is designed to help — but funding is never automatic.
Park homes can qualify for ECO4 support if the household meets low-income or qualifying-benefit criteria, or is approved through ECO4 Flex schemes administered by local authorities across the UK. A full property assessment is required to confirm suitability.
ECO4-funded park home insulation may include:
For park homes on rented plots, written consent from the park owner or site management is required before any external insulation work begins. This ensures compliance with site regulations and installation approval.
Park home insulation costs vary with the size of the property, its current insulation level and the retrofit system used (external cladding, internal lining, roof or floor insulation). Larger park homes need more materials and labour, especially where scaffolding or structural preparation is required.
In most cases external wall insulation is the highest-impact solution, while internal insulation can be more cost-effective but reduces internal floor space. ECO4 funding may cover up to 100% of installation costs depending on eligibility, property assessment, EPC rating and scheme approval.
| Property type | Description | Indicative cost range | ECO4 funding |
|---|---|---|---|
| Single unit (2-bed park home) | Standard-sized park home with typical insulation upgrades to walls, roof and floor | £6,000–£10,000 | May cover up to 100% (subject to eligibility) |
| Double unit (3-bed park home) | Larger park home requiring more extensive insulation materials and installation time | £8,000–£14,000 | May cover up to 100% (subject to eligibility) |
Park home insulation in the UK must comply with building regulations, ECO4 scheme requirements and park site rules, depending on the type of work being carried out. Internal insulation typically does not require planning permission, but external systems such as cladding or over-cladding may require approval from the park owner and, in some cases, local authority consent.
All installations must follow appropriate energy efficiency and safety standards, so the materials used are suitable for lightweight and mobile home construction. Breathable insulation systems are essential to prevent the condensation, damp and structural issues commonly associated with poorly ventilated park homes.
On rented plots, park owner or site management consent is usually required before any external alterations are carried out, ensuring the installation meets site regulations and contractual agreements.
Compliant Retrofits is a UK specialist in park home insulation and ECO4-funded retrofit solutions, delivering tailored systems designed specifically for lightweight and mobile home construction.
We understand the unique challenges of park home projects — thin walls, condensation risks and limited structural capacity — and design every installation to improve thermal efficiency while protecting the building fabric.
We use breathable, high-performance materials that help prevent condensation and long-term damp issues — essential in lightweight park home construction.
Full support with ECO4 grant applications for park homes — helping eligible homeowners access funding where available, subject to assessment and scheme approval.
Our external cladding and internal insulation systems are designed to reduce heat loss and improve comfort while minimising disruption during installation.
From initial consultation to completion, we deliver a fully managed service with expert guidance at every stage — a smooth and compliant retrofit process.
You may qualify. Park homes (including static and mobile homes) can be supported under ECO4 where the household meets low-income or qualifying-benefit criteria, or is approved through ECO4 Flex by the local authority — ECO4 runs until 31 December 2026. Contact us for a free eligibility check.
If you rent your plot, yes — written consent from the park owner or site management is required before external work begins. We advise on gaining consent before proceeding.
Typically 1–2 weeks depending on the system and property size. External cladding takes longer than internal lining because scaffolding is required.
Not when installed correctly with breathable materials and proper ventilation — we design specifically for park home construction.
Usually not — but external insulation may need approval depending on site rules and park owner consent. We check this for you during your free consultation.
