Internal Wall Insulation for Solid Walls is an effective solution designed to reduce heat loss in homes with solid stone or brick walls. Unlike cavity walls, solid walls lack an inner gap, making them more prone to energy loss. Internal wall insulation involves fitting insulated boards or stud walls to the inside of your existing walls—helping retain warmth and boost your home’s energy efficiency.
If your property was built before the 1920s or doesn’t have cavity walls, there’s a strong chance it could benefit from insulating solid stone walls internally or insulating solid brick walls internally to stop unnecessary heat loss and lower your heating bills.
By professionally insulating from the inside, we create a thermal layer that stops heat from escaping while keeping your interior space cosy—especially during harsh Scottish winters.
✅ Significantly reduces heat loss through solid walls
✅ Ideal for older homes built with solid stone or brick
✅ 100% free for eligible homes under GBIS and ECO4 government schemes
Whether you’re a homeowner or tenant, internal wall insulation for solid walls is one of the most cost-effective energy upgrades for achieving a warmer, more energy-efficient home.
The Internal Wall Insulation Grant is part of the UK Government’s eco-efficiency programmes — specifically under schemes like the Great British Insulation Scheme (GBIS) and ECO4. These initiatives are created to support homeowners and qualifying tenants across Scotland in making their homes warmer and more cost-effective by installing insulation at no personal expense.
If your home was built before modern insulation standards — especially properties with solid walls — there’s a high chance your home lacks insulation. This includes solid stone walls and solid brick walls, which tend to absorb and release heat easily, causing unnecessary heat loss.
By insulating solid stone walls internally or insulating solid brick walls internally, we apply an insulation layer inside your home’s external walls to prevent heat from escaping and to create a more energy-efficient environment.
✅ Fully government-funded with no hidden charges
✅ Installation covers all materials and labour
✅ Ideal for homes with EPC ratings between D and G
These improvements can help reduce annual heating bills by as much as £300+, boost your EPC rating, and make your home much more comfortable during Scotland’s colder months.
You could be eligible for a completely free internal wall insulation grant through the GBIS or ECO4 scheme, depending on your home’s energy rating and household circumstances.
If you’re a homeowner, you may still qualify even without benefits, particularly if your solid wall home is energy inefficient and falls under the right tax band.
However, tenants must be receiving at least one qualifying benefit to access this grant.
If you’re over the age of 70, you may qualify for a free internal wall insulation grant under the UK Government’s ECO4 and GBIS schemes.
