THE INVISIBLE PROBLEM

WHAT IF THE COMFORT YOU’RE PAYING FOR IS ESCAPING?

Uninsulated walls and lofts let warmth leave the building. We find where the home is losing heat, explain the options plainly, then only recommend work that fits the property.

Up to this much heat can be lost through uninsulated cavity walls, depending on the property.

THE WARMER GROUP’S HOME INSULATION SERVICES

INSULATE WHERE IT MATTERS.

These are the three practical services we provide. One survey connects the symptom you feel to the part of the building that needs attention.

01

CAVITY WALLS

Keep more warmth inside without changing how your home looks.

Arrange a suitability survey →

We inspect the construction and cavity first, then specify bonded bead or mineral wool where appropriate. Small access holes are filled and matched after installation.

02

LOFTS

Upgrade the thermal layer above the rooms you live in.

Existing depth, access, ventilation and stored items all matter. The survey gives you a practical plan before installers arrive.

03

THERMAL IMAGING

See cold bridges, gaps and unexpected heat loss.

STRAIGHT ANSWERS

BEFORE YOU MAKE A HOLE IN THE WALL.

Is every home suitable for cavity wall insulation?

No. Wall construction, cavity condition, exposure and existing insulation all need to be checked first. That is why the process starts with a property survey.

How disruptive is the installation?

Installers work from the outside through a pattern of small access holes, then fill and match them afterwards. Your surveyor will explain access and likely timings for your home.

Is the work guaranteed?

Qualifying cavity wall installations are covered by a 25-year CIGA guarantee. The applicable cover is confirmed before work begins.

Can you check whether funding is available?

Yes. The team can discuss current schemes and eligibility. Availability changes, so this should be checked at the time of enquiry.
