Cavity wall insulation for landlords for Islington properties
We cover Islington and the N1 postcode district, including nearby Highbury, Holloway and Camden Town. It is around 2 miles north-east of London.
Blocks of flats in Islington are surveyed as a whole, because the cavity runs across every flat in the building. Work on Islington rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.
Before any material is chosen, exposure is checked. Much of Greater London sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.
On the rules side, in Islington filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England
In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

Planning for EPC C
Government has confirmed that private rented homes in England will need to reach EPC band C by October 2030, with a £10,000 cost cap and exemptions. A filled cavity often contributes a meaningful share of the points needed, and it can be done with tenants in place because the work is outside.
