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

Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
How much does loft ventilation cost in Holyhead?
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 Holyhead
How do I pay for work in Holyhead?
Payment terms are set out on your quote. We never ask for payment on the doorstep or in cash.
Is loft work in Holyhead 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.
Can a landlord in Holyhead book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
