What is loft ventilation?
Most pitched roofs are ventilated at the eaves, sometimes with high-level vents as well. Insulation pushed into the eaves can block that path, which is why we fit ventilation trays. More about loft ventilation.
- Eaves trays where insulation could block airflow
- A note of air leaks from the house that need sealing
- Soffit, tile or ridge vents as specified

How much does loft ventilation cost in Stevenage?
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 Stevenage
Do you charge extra to travel to Stevenage?
Not normally. Our guide prices include normal travel to Stevenage. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
Can a landlord in Stevenage book work for a tenanted house?
Yes. We can arrange access with the tenant directly and send you photos once the work is finished.
Do you take on jobs outside Stevenage?
Yes. We also work in Hitchin and Letchworth Garden City and elsewhere in Hertfordshire.
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.
Will extra vents make my house colder?
No. The vents ventilate the loft above the insulation, not the rooms below.
