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

Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
How much does loft ventilation cost in Harlow?
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 Harlow

How soon can you visit a home in Harlow?
We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.
Can you visit Harlow outside working hours?

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.
