How Can We Help You Get a Grant?
With internal solid wall insulation, property owners have more ways than ever to benefit from government insulation grants and improve energy efficiency. Under the government's ECO4 solid wall insulation grant scheme, homes in the UK with at least 50% solid wall construction that currently lack insulation may qualify for funding.
Rural Energy Saving Grants takes care of the entire grant procurement process, screening eligibility, advising on the best available schemes, and coordinating with accredited installers. We understand eligibility criteria, local authority requirements, and how to maximise your chances for rural energy grants in 2025 and beyond.

How Does ECO4 Help with Solid Wall Insulation?
ECO4 is a leading scheme in the UK, designed to bring energy saving insulation upgrades to those most in need. To receive insulation grants through ECO4, your home must have at least one exterior solid wall and over half of its surface must be un-insulated solid wall construction.
Internal wall insulation can lead to significant long-term savings through reduced energy bills. We regularly help clients across the UK (excluding Northern Ireland) get their insulation fully funded, removing one of the biggest barriers for homeowners and tenants. With rural energy grants, including those supported by major energy suppliers, our service makes energy efficiency achievable, and affordable,for everyone who qualifies.
To qualify for a cavity wall grant, your property generally needs:
Wall Type
At least one exterior solid wall and over half of its surface must be un-insulated solid wall construction.
Household circumstances
Those on certain benefits, with qualifying medical conditions, or an income under £31,000 will likely meet criteria.
EPC rating
Most grants prioritise homes with an EPC of E, F, or G.
Property suitability
We check wall type, and overall condition to ensure your home can receive insulation safely.
FAQs
What’s the difference between external and internal wall insulation?
External wall insulation is fitted to the outside of your property’s solid walls, whereas internal wall insulation is applied to the inside surfaces. Both options reduce heat loss and boost energy efficiency, but the chosen method may depend on property type, aesthetics, and grant eligibility.
How much energy can I save with wall insulation?
Solid wall insulation can significantly reduce heat loss and lower your energy bills. The exact savings depend on property size and energy rates, but many households report substantial annual reductions after solid wall insulation installation through government insulation grants.
How long does the installation take for solid wall insulation?
Installation usually takes between a few days and two weeks, depending on the size of your property and whether you choose internal or external wall insulation. Rural Energy Saving Grants coordinates accredited installers to ensure a smooth process.
Will wall insulation installation cause disruption to my home?
Some disruption can occur, particularly for internal wall insulation, as it requires access to rooms and temporary removal of fixtures. External installation is generally less intrusive inside the home. We work to minimise inconvenience and keep you informed throughout.
Are there any ongoing maintenance requirements for wall insulation?
Solid wall insulation, once installed correctly, requires minimal ongoing maintenance. However, it’s wise to inspect the exterior surfaces and internal walls occasionally for any signs of damp or damage to ensure long-term performance.
Who qualifies for insulation grants in the UK through Rural Energy Saving Grants?
UK property owners or tenants in off-gas homes who receive certain benefits, have a medical condition, or have a household income under £31,000 may qualify for insulation grants, subject to property eligibility and grant scheme rules.
