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
- Eaves trays where insulation could block airflow
- A note of air leaks from the house that need sealing

Photos of the finished loft
You see the work done without climbing the ladder.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
No pressure selling
You get everything in writing and decide in your own time.
How much does loft ventilation cost in Cardiff?
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 Cardiff
Do you take on jobs outside Cardiff?
Yes. We also work in Penarth and Trowbridge (South Glamorgan) and elsewhere in South Glamorgan.
What do I need to do before you arrive in Cardiff?
Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.
Is loft work in Cardiff different from anywhere else?
The method is the same, but older terraces, cottages and newer estates each have their own quirks: lath ceilings, low pitches or trussed roofs. We plan for the loft we find.
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.
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.
