Why choose our underfloor insulation services

Uninsulated floors are a major source of heat loss in many homes, leading to thermal bridging and uncomfortable cold spots. Our process effectively seals these gaps, preventing cold air from rising through your floorboards and helping you retain valuable warmth. By improving the thermal efficiency of your property, you not only enjoy a more consistent indoor climate but also work towards a higher EPC rating, which is essential for meeting modern energy standards and MEES compliance for rental properties. We take pride in our precision and attention to detail during every installation.

How we manage your insulation and retrofit project

At Global Energy Insulation, we operate as fully PAS 2030 accredited specialists, ensuring that every project meets rigorous industry standards. We provide expert PAS 2035 retrofit coordination to ensure your home is treated as a complete system, rather than just isolated components.

This approach provides a seamless, end-to-end service for clients across South Wales and the South West.

Underfloor Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited underfloor insulation, draught-proofing, and heat loss reduction services across South Wales and South West England and South Wales.

How much mess does the installation create?

+

If you have a crawl space under your home, we can often do the work without lifting your floorboards, meaning there is very little disruption to your home. If we do need to lift boards, our team works methodically to make sure the process is clean and tidy.

Will underfloor insulation cause my floors to rot?

+

No, provided it is installed correctly. We make sure that your sub-floor ventilation (air bricks) stays clear. This keeps the air moving and protects your timber joists from moisture build-up. This is why using a PAS 2030 accredited installer is so important.

How long does it take to pay for itself?

+

With energy prices remaining high, the "payback period" for floor insulation has shortened significantly. Most homeowners find that the savings on their heating bills cover the cost of the installation within a few years, all while enjoying a much more comfortable home.

Can you insulate solid concrete floors?

+

Yes, but the process is different. For solid floors, we usually lay high-density insulation boards on top of the concrete, followed by a new floor covering. This can raise the floor height slightly, so we will discuss the best options for your specific property during our site visit.
