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
Why book with us in Nailsea
No pressure selling
You get everything in writing and decide in your own time.
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.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
We measure before we quote
Existing depth, joist spacing, wiring and the tank are checked, not guessed.
How much does loft ventilation cost in Nailsea?
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 England
In England, a loft insulated across more than half its area should reach a U-value of 0.16 W/m²K. Insulation alone is not usually notified to building control. How the rules work across the UK.
Questions about loft ventilation in Nailsea
Do you take on jobs outside Nailsea?
Yes. We also work in Portishead and Clevedon and elsewhere in Somerset.
What do I need to do before you arrive in Nailsea?
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.
Do you cover all of BS48?
Yes, we cover the BS48 postcode district and the districts around Nailsea.
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.
