What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Where there are no vents, we add soffit vents, tile or slate vents, or ridge vents, depending on the roof covering and the underlay. More about loft ventilation.
- Soffit, tile or ridge vents as specified
- A note of air leaks from the house that need sealing
- Eaves trays where insulation could block airflow
Why book with us in Powys
Fixed written price
The price on the quote is the price you pay. It only changes if you change the job, or if we find something hidden, such as rot, and you agree the change in writing first.
Clear contact details
Your quote says who to call with questions before, during and after the work.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
How much does loft ventilation cost in Powys?
This work is not an energy-saving material for VAT, so it is standard-rated if VAT applies. Where it is done alongside insulation, the quote shows each part separately.
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 Powys
Do you cover the whole of Powys?
Yes. We cover every town and village in Powys, including Brecon, Builth Wells and Llandrindod Wells.
Which council covers my address in Powys?
Addresses in Powys come under Powys council. The council matters for building control questions and some funding schemes.
Does my loft need ventilation after insulation?
A cold loft needs a path for outside air, usually at the eaves. New insulation must not block it, which is why we fit eaves trays.
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.
