What is internal wall insulation?
Internal wall insulation adds insulated boards or layers to the inside of external walls to stop heat escaping through solid brick or blockwork. It’s an effective way to warm up older homes that don’t have cavity walls and can make a big difference to comfort and energy costs.
Can I get internal wall insulation for free?
Yes. Through the government’s ECO4 scheme, eligible households can access internal wall insulation grants that often cover the full cost of installation. In some cases, a small contribution may be needed, but most qualifying homes pay nothing.
Who can qualify for an internal wall insulation grant?
You may be eligible if:
You receive means-tested benefits such as Universal Credit or Pension Credit, or your local authority refers you under ECO Flex.
Your home has an EPC rating of D to G.
The property is built with solid walls rather than cavity walls.
How does internal wall insulation improve my home?
It helps to keep warmth inside during winter and makes rooms feel less cold to the touch. It can also cut heat loss by up to 45% in older solid wall properties, lowering your energy use and reducing heating bills.
How is the insulation fitted?
Insulated boards are fitted to the inside of external walls, then finished with plaster ready for decoration. The process takes a few days depending on the size of the property and causes minimal disruption to daily life.
Is my home suitable?
Internal wall insulation is ideal for homes built before the 1920s that have solid brick or stone walls. If your home has cavity walls, other insulation options will usually be more suitable.
Will I need to redecorate afterwards?
Because plaster and paint are applied after installation, redecorating is part of the process. Many homeowners use this as an opportunity to refresh the room’s look while improving efficiency.
How long does the work take?
Most installations take between three and five days, depending on the number of rooms being insulated. All work is carried out by TrustMark-registered installers in line with PAS 2030/2035 standards.
What kind of savings can I expect?
Savings vary by property, but many households see a reduction of around 20–30% on heating bills after internal wall insulation is installed. It also helps to eliminate draughts and cold spots, improving overall comfort.
