A clear route from concern to evidence
We inspect it. We show you what we find. Then you decide what happens next.
Start with the room that will not stay warm, the temperature difference you keep noticing or the insulation work that concerns you. Thermorite reviews the property before discussing a remedy.
Tell us what is worrying you. Thermorite will confirm eligibility and the next step.
Four simple steps from concern to a clearer answer
- 01
Step 01
Tell us what is wrong
Share your postcode, property type, the comfort or insulation concern you have noticed, and anything you know about earlier work. Old paperwork can help, but is not required.
- 02
Step 02
We check eligibility
Thermorite reviews the location and property details, then contacts you about a free visit.
- 03
Step 03
We investigate
Where suitable, borescope video helps inspect visible conditions at accessible cavity locations.
- 04
Step 04
You get a clear explanation
Thermorite explains what was seen, what it may mean and whether leaving, rectifying, removing or replacing material may be worth discussing.
No predetermined result
The findings shape the recommendation—not a pre-selected treatment.
No cavity work may be needed
The insulation seen at the inspected points may appear satisfactory, so no remedial cavity work may be recommended from those findings.
A localised issue may be addressed
A visible gap, obstruction or other defined concern may support a proportionate rectification discussion rather than full removal.
Extraction may be considered
Where the visible condition and wider property information support it, extraction may be discussed as part of an agreed remedial scope.
Remove and replace may be considered
If removal is justified and the cavity and property appear suitable, an appropriate new insulation option may be considered afterwards.

A practical first step
The process is designed to replace guesswork with a clearer conversation.
What you notice at home, what is visible where access is suitable and the wider property context each have a role in the discussion.
