What is a loft condensation investigation?
We inspect the loft in daylight and by torch, measure moisture in the timbers, check the underlay, ventilation, insulation and the routes that let warm air in from the house, and look at the roof from outside. You get written findings with photos and a plain list of what we recommend, which may include work we do not offer. More about a loft condensation investigation.

How much does a loft condensation investigation 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 a loft condensation investigation in Hertfordshire
Which council covers my address in Hertfordshire?
Addresses in Hertfordshire come under Hertfordshire council. The council matters for building control questions and some funding schemes.
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.
Is condensation in my loft normal?
A little on the coldest nights can be normal, especially with old felt. Dripping, wet insulation or mould are signs to investigate.
Is the investigation fee taken off the work?
The investigation is priced on its own so the advice is not tied to selling work. You decide what to do afterwards.
