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
Why book with us in Hertfordshire
Clear contact details
Your quote says who to call with questions before, during and after the work.
Tidy work
Dust sheets on the route in and every bit of packaging taken away.
Eaves kept clear
Insulation is held back from the eaves so the loft can still ventilate.
Plain-English advice
We explain what we find in plain English, and say so when nothing needs doing.
How much does loft ventilation cost in Hertfordshire?
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 Hertfordshire
How do I book a survey in Hertfordshire?
Send the form or call us. We call back to agree a time and confirm it in writing.
Can you quote for several properties in Hertfordshire?
Yes. Landlords and agents can send a list of addresses and we will survey them in as few visits as we can.
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.
