Keep Heat In and Cold Draughts Out

Suspended timber floors can allow cold air to enter from below, making rooms feel draughty and uncomfortable. Underfloor insulation helps reduce heat loss and improves comfort from the ground up.

Commercial Improvements Ltd installs underfloor insulation for suitable homes, landlords and funded retrofit programmes. Before any work starts, we check the floor type, sub-floor access, ventilation, moisture condition, pipework, services and any defects that may affect the installation.

Where the property is suitable, insulation is fitted securely below the floor between the joists, helping to reduce draughts and heat loss while maintaining the necessary airflow below the floor.

Why Install Underfloor Insulation?

Underfloor insulation can make a noticeable difference to comfort, especially in older homes with suspended timber floors and cold draughts from below.

Warmer Floors
Insulating below the floor helps reduce cold surfaces and improves comfort, especially in ground-floor rooms.
Reduced Draughts
Gaps between floorboards and around skirting areas can allow cold air in. Underfloor insulation helps limit draughts from below.
Lower Heat Demand
When less heat escapes through the floor, the heating system may not need to work as hard to maintain a comfortable temperature.
Better Home Comfort
Rooms can feel warmer and more comfortable, particularly during colder months when floors often feel cold underfoot.
Improved Energy Performance
Underfloor insulation supports a fabric-first approach by improving the thermal performance of the building fabric.
Grant Support Available
Where funding is available, we can check whether your home may qualify for underfloor insulation through a suitable scheme.

How Our Underfloor Insulation Service Works

Step 1
Initial Enquiry
We collect basic property details and ask about floor type, access points, cold draughts, damp concerns and any previous insulation work.
Step 2
Floor and Access Survey
Our surveyor checks whether the property has a suitable suspended timber floor, safe access and enough sub-floor space to complete the work.
Step 3
Moisture and Ventilation Checks
We review sub-floor ventilation, damp risk, timber condition, pipework and services before confirming whether installation is suitable.
Step 4
Professional Installation
Insulation is fitted securely between the floor joists from below, with care taken around services and ventilation routes.
Step 5
Completion Check and Handover

Is Underfloor Insulation Right for Your Home?

Underfloor insulation is most suitable for homes with suspended timber floors and safe access below the floor. Our survey helps confirm whether the measure can be installed properly and safely.

Suspended Timber Floor
The property usually needs a suspended timber floor with a suitable void below for insulation to be fitted between the joists.
Safe Access Required
We check whether there is safe access below the floor through a hatch, cellar, basement or suitable access point.
Moisture Risk Reviewed
Existing damp, poor timber condition or water ingress should be addressed before underfloor insulation is installed.
Sub-Floor Ventilation Protected
Airflow below the floor is important, so we make sure ventilation routes are not blocked by the insulation.
