We cover Waterlooville and the PO7 postcode district, including nearby Havant, Portsmouth and Fareham. It is roughly 16 miles east of Southampton.

Per-address photo records for Waterlooville properties make compliance files and EPC updates straightforward. Blocks of flats in Waterlooville are surveyed as a whole, because the cavity runs across every flat in the building.

Local weather affects which walls can be filled. Hampshire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.

In terms of approvals, in Waterlooville filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.
