What is a thermal imaging survey?
Thermal images work best when the house is heated and the outdoor temperature is low, ideally at least 10°C lower than indoors, so surveys are booked for cold mornings or evenings. We image the top-floor ceilings, the room-in-roof if you have one and the loft, and explain what each cold patch is likely to be. More about a thermal imaging survey.

How much does a thermal imaging survey 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 thermal imaging survey 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.
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.
When is the best time for a thermal imaging survey?
On a cold, still, dry day with the heating on for several hours. Bright sun or rain on the roof makes outside images unreliable.
Is a thermal imaging survey worth it?
It is most useful where a problem is hard to find or you want to check someone else's work. For a simple loft you can see into, a standard survey is usually enough.
