Cavity wall insulation for landlords for Belfast properties

Belfast sits in County Antrim. We work across the BT1 district, including nearby Newtownabbey, Lisburn and Carrickfergus.

Per-address photo records for Belfast properties make compliance files and EPC updates straightforward. For commercial buildings in Belfast, the survey also considers building use and fire requirements before a material is specified.

Every elevation is judged on its own exposure. Parts of County Antrim face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

In terms of approvals, in Belfast inserting cavity wall insulation needs a building control application to the council before work starts.

Funding in Northern Ireland

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000.

Cavity wall insulation for landlords in Belfast: questions

Are there grants for insulation in Belfast?

In Northern Ireland, the Affordable Warmth Scheme helps eligible households with a gross income under £23,000. We cannot promise funding, but we will point you to the right official route.

Is my Belfast home too exposed for cavity insulation?

Parts of County Antrim get some of the heaviest wind-driven rain in the UK, so the survey is stricter and some walls are better left unfilled. The survey records the exposure of each wall before recommending a material, or recommending against filling.

Do you cold-call in Belfast?

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