How does external wall insulation work?

External wall insulation or EWI is a layer of insulation material that’s fixed to the outside walls of your home. Once installed, a protective covering of cladding or render is applied to the insulation to prevent it being damaged by the elements. There is a wide range of external finishes to choose from including panelled, textured, pebble-dashed, smooth, or tiled. EWI is the ideal way to improve the energy efficiency and look of your Derbyshire-based property.

Do I need planning permission for EWI?

“Permitted development rights” allow homeowners to make certain changes to their Derbyshire property without planning permission. EWI is classified as ‘permitted development’, so doesn’t usually require planning permission.

There are some circumstances, however, such as if your building is listed or in a conservation area, where you are likely to need planning permission to install EWI. We always recommend checking with your local planning authority before EWI is installed on your home.

Can I install external wall insulation myself?

External wall insulation involves using several complex processes to first apply insulation material to your property and then protect is from the elements with a resistant finish. Because of this, we wouldn’t recommend undertaking EWI on your own, even if you are very experienced with DIY.

External Wall Insulation Grants Derby

If you are a homeowner or private tenant, you may qualify for a government grant to receive help towards the cost of installing external wall insulation. These government grants contribute to the funding of insulation materials and installation. So, that means you won’t need to cover the total bill on your own. Grants are available to everyone, regardless of home-owner status or income.
