Cavity wall insulation for landlords for Harwich properties

Harwich sits in Essex, about 37 miles north-east of Chelmsford. We work across the CO12 district, including nearby Clacton-on-Sea and Colchester.

Blocks of flats in Harwich are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Harwich, we survey in batches and return a result sheet and fixed price per address.

Exposure matters for every cavity wall. Much of Essex 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 Harwich 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.

Sources: GOV.UK: extending the ECO4 end date, government response; GOV.UK: Warm Homes Plan.

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.
