Social housing and estate programmes for Caernarfon properties

Caernarfon sits in Gwynedd, around 6 miles south-west of Bangor. We work across the LL55 district, including nearby Bangor, Porthmadog and Holyhead.

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

Local weather affects which walls can be filled. Parts of Gwynedd 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.

On the rules side, in Caernarfon filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Funding in Wales

In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.

Sources: Welsh Government: warmer and more energy efficient homes (July 2026); GOV.UK: extending the ECO4 end date, government response.

Quality after ECO

The National Audit Office's October 2025 report found serious failings in some government-funded installs. We work survey-first, record every stage, and name the installer and guarantee on each order.
