Internal wall insulation – works by adding a thermal layer of material to the existing wall. Rigid insulation is particularly appropriate where you need to keep the outside of your home looking the same.

External wall insulation – involves fixing a layer of insulation material to the wall, then covering it with a special type of render or cladding. This creates a finished look, which can make your house look brand new.

What is Cosy City?

Cosy City is a scheme targeted at helping households throughout Norwich to save energy and save money. The Cosy City scheme can help people to improve the quality of their homes, making them cosier, warmer and more affordable.


Assessments and installations are now able to go ahead, with enhanced safety procedures in place. Before any visits take place the team will get in touch to confirm the household is symptom free. Social distance will be maintained within the property.

Applications for grants for Solid Wall Insulation in the Norwich City Council area are now closed.

We are only accepting applications for cavity wall insulation and loft insulation.


Loft insulation and Cavity wall insulation is subject to survey. The funding available is dependent on the free survey carried out.


Cosy City does not offer grants to council tenants. It only offers grants to private homeowners and private tenants.
