Cavity wall suitability survey for Southampton properties

If your property is in Southampton or the SO14 district or nearby Hythe, Totton and Eastleigh, it is within our Hampshire coverage. Southampton is one of the main towns we cover in Hampshire.

Buyers and sellers in Southampton often book this check when a survey report or EPC raises questions about the walls. Every inspection point in Southampton is photographed and logged, so you have a record to show a buyer, lender or contractor.

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.

On the rules side, in Southampton filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Cavity wall suitability survey in Southampton: questions

Do you cold-call in Southampton?

No. We only come out when you have asked us to. If someone cold-calls offering free insulation, check before you agree to anything.

Do you work on rented homes in Southampton?

Yes. Landlords and agents in Southampton can book batch visits, and work is arranged around tenants.

Is there VAT on a cavity wall survey in Southampton?

The survey is free when it is for an install quote. A standalone survey report is not insulation, so it is normally standard-rated for VAT, and the price you are quoted includes it.

Is my Southampton home too exposed for cavity insulation?

Hampshire has a mix of moderate and more exposed sites, so each wall is judged on its own. The survey records the exposure of each wall before recommending a material, or recommending against filling.
