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 Welwyn Garden City
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
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.
No pressure selling
You get everything in writing and decide in your own time.
Clear contact details
Your quote says who to call with questions before, during and after the work.
How much does loft ventilation cost in Welwyn Garden City?
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 Welwyn Garden City
Will I get a written quote for work in Welwyn Garden City?
Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.
What do I need to do before you arrive in Welwyn Garden City?
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.
Can a landlord in Welwyn Garden City book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
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.
