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
  • Soffit, tile or ridge vents as specified
  • Eaves trays where insulation could block airflow

Eaves kept clear

Insulation is held back from the eaves so the loft can still ventilate.

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 Dorset

Which council covers my address in Dorset?

Councils in Dorset include Dorset and Bournemouth, Christchurch and Poole. Your council matters for building control questions and some funding schemes.

Do you cover the whole of Dorset?

Yes. We cover every town and village in Dorset, including Bournemouth, Poole and Weymouth.

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.
