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

How much does loft ventilation cost in Welling?
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.

Not normally. Our guide prices include normal travel to Welling. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
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.
