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.
- Soffit, tile or ridge vents as specified
- Eaves trays where insulation could block airflow
- A note of air leaks from the house that need sealing

How much does loft ventilation cost in Chelmsford?
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 Chelmsford
How soon can you visit a home in Chelmsford?
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.
Do you take on jobs outside Chelmsford?
Yes. We also work in Billericay and Witham and elsewhere in Essex.
Can you visit Chelmsford outside working hours?
Ask about early, late or weekend appointments when you get in touch, and we will tell you honestly what we can offer.
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.
