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.

- Soffit, tile or ridge vents as specified
- A note of air leaks from the house that need sealing

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 Portsmouth
Do you take on jobs outside Portsmouth?
Yes. We also work in Gosport and Fareham and elsewhere in Hampshire.
Can a landlord in Portsmouth 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 charge extra to travel to Portsmouth?
Not normally. Our guide prices include normal travel to Portsmouth. If an address needs a ferry or an unusually long journey, we tell you the cost before you book.
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.
