What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Insulation pushed into the eaves can block that path, which is why we fit ventilation trays. More about loft ventilation.
- Soffit, tile or ridge vents as specified
- Eaves trays where insulation could block airflow
- A note of air leaks from the house that need sealing

How much does loft ventilation cost in Gwynedd?

Building regulations in Wales
Wales has its own Approved Document L. Insulation alone is not normally notified, but conversions need building control. How the rules work across the UK.
Questions about loft ventilation in Gwynedd
Which council covers my address in Gwynedd?
Councils in Gwynedd include Gwynedd and Isle of Anglesey. Your council matters for building control questions and some funding schemes.
Do you cover the whole of Gwynedd?
Yes. We cover every town and village in Gwynedd, including Bangor (Gwynedd), Caernarfon and Dolgellau.
My bathroom fan vents into the loft. Is that a problem?
Yes. It pumps warm, wet air straight into the coldest part of the house. The duct should run to outside through a vent tile, soffit or wall.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
