Cavity wall insulation for landlords for Grantham properties

Grantham is among the towns we cover in Lincolnshire, alongside Stamford, Spalding and Lincoln. It is roughly 22 miles south of Lincoln.

Work on Grantham rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Grantham are surveyed as a whole, because the cavity runs across every flat in the building.

Wind-driven rain is the first thing the surveyor weighs up. Much of Lincolnshire 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.

In terms of approvals, in Grantham 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.
