Floor insulation may not be the flashiest home upgrade, but it delivers big results in silence. Beneath your carpets, tiles, and hardwood lies one of the most critical barriers between your cosy living space and the cold, energy-hungry void below.
When you book an EPC assessment, floor insulation plays a noticeable role in determining how much heat your home hangs onto. The better the insulation, the better the score.

Why Floors Are a Major Source of Heat Loss
Heat loves an escape route, and in many homes, that escape route is straight through the floor. Older properties with suspended timber floors can lose up to 15% of heat from below.
Floor insulation helps:
• Keep rooms warmer for longer
• Reduce heating bills
• Prevent cold draughts
• Improve EPC scores and property value
• Increase comfort underfoot (toasty toes!)
Every degree of retained heat counts toward better energy performance.
Which Floors Benefit Most?
Different floor types behave differently in the EPC calculation:
| Floor Type | Heat Loss Risk | Insulation Opportunity |
|---|---|---|
| Suspended timber | High | Underfloor insulation + draught sealing |
| Solid concrete | Moderate | Insulation above or below the slab |
| Modern insulated slab | Low | Already built to standard |
EPC assessors check what type of floor your home has and whether insulation is visibly installed.
What EPC Assessors Look For
During an EPC survey, inspectors examine:
✅ Insulation thickness and material
✅ Flooring type and construction age
✅ Draught-proofing around skirting boards
✅ Insulation continuity (no cold gaps)
✅ Whether upgrades are possible
If insulation cannot be visually confirmed, assumptions must be used, which may lower the score.
Don’t worry, our expert assessors know all the tricks:

How Much Can Floor Insulation Improve EPC Ratings?
Upgrading an uninsulated floor is often enough to push a property up one EPC band, particularly when combined with heating controls or loft insulation.
Examples of EPC impact:
• Insulating timber floors: strong rating improvement
• Solid floor insulation: good rating improvement
• Clip-on insulation during renovations: excellent for value vs cost
A warmer rating makes buyers and renters happier, too.
Best Options for Floor Insulation
Off-the-shelf solutions that EPC assessors love:
• Mineral wool between joists
• PIR rigid boards beneath floor coverings
• Foil-faced insulation rolls
• Draught-proofing membranes and sealants
• Underfloor heating systems with insulation backing
Even small improvements add up fast.
Signs Your Floor Could Be Costing You Energy
Look out for:
• Persistent cold floors
• Chilly draughts through floorboards
• High heating bills despite insulation elsewhere
• Homes built before early 1990s
If your property matches these, you’re a perfect candidate for an EPC-friendly upgrade.
