How to Choose a Insulation Installer in Caerphilly

Check TrustMark registration — this is required for all government-funded insulation work.
Ask about PAS 2035 compliance — for grant-funded work, a retrofit assessment must be done first.
Check for cavity wall suitability — not all cavities can be safely filled. Exposed or sheltered walls matter.
Ask about ventilation — insulating without considering airflow can cause damp and condensation.
Get the guarantee in writing — cavity wall insulation should come with a 25-year CIGA guarantee.
Ask if they handle grant applications — good contractors manage the ECO4 or GBIS paperwork for you.
