Free Internal Wall Insulation (IWI) Grants
Internal Wall Insulation, or IWI, creates warmer, more energy efficient homes by adding a layer of insulation to the internal walls. IWI can be added to buildings of any age, and it’s usually much cheaper to install than external wall insulation. And if you qualify for the Government’s ECO4 scheme, an internal wall insulation grant could cover the full cost of your installation. You’ll find out more about that below.
What is Internal Wall Insulation?
Internal Wall Insulation, or IWI, creates warmer, more energy efficient homes by adding a layer of insulation to the internal walls. IWI can be added to buildings of any age, and it’s usually much cheaper to install than external wall insulation.

How does it work?
Internal wall insulation creates a thermal barrier that traps warm air in a room and prevents it from escaping. There are several ways of installing IWI. Fixing rigid insulation board or insulated plasterboard to your existing interior walls are perhaps the simplest and most space saving options. All works are completed with a plastered finish.
Internal wall insulation does take space. Each wall will be around 100mm thicker, but it’s a trade off that could create a much warmer home that’s cheaper to heat.
