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.
- A note of air leaks from the house that need sealing
- Eaves trays where insulation could block airflow
- Soffit, tile or ridge vents as specified
Why book with us in Penarth
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.

Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
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.
How much does loft ventilation cost in Penarth?
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 Penarth
Do you charge extra to travel to Penarth?
Not normally. Our guide prices include normal travel to Penarth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Do you take on jobs outside Penarth?
Yes. We also work in Cardiff and Barry and elsewhere in South Glamorgan.
How soon can you visit a home in Penarth?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
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.
