Frequently Asked Questions

Some frequently asked questions about the service that you may have questions about

Is my floor type suitable for underfloor insulation?

Underfloor insulation is generally ideal for homes with suspended timber floors, where there's a crawl space or void beneath the floorboards. If your ground floor has air bricks on the outer walls, it's a good sign that your floor is suspended and ventilated—making it suitable.
However, if your home has solid concrete floors, this method won't apply. But don’t worry—we’ll recommend alternative insulation upgrades, such as solid floor insulation or room-in-roof solutions, depending on your home’s structure.

Will I need to remove my flooring?

No full removal is typically required. Our installers carefully lift selected floorboards to access the space beneath and insert insulation with precision. Once installed, the boards are refitted securely, leaving no visible trace of disruption.
We take great care to protect your flooring, furniture, and décor, and always leave your home tidy and dust-free.

How long does it take?

The entire process usually takes one working day, although larger properties or homes with more complex layouts may require slightly more time.
Our experienced team works quickly and professionally to complete the installation with minimal disruption to your daily routine.

Will it help reduce my energy bills?

Absolutely. Homes with suspended floors can lose up to 15% of their heat through the ground. By insulating the underfloor space, we help you retain warmth more effectively—meaning your heating system runs less frequently, and your home stays cosier for longer.
This can lead to noticeable savings on your energy bills, especially during colder months.

Can I get a grant for this?

Yes, in many cases. If your home has a low Energy Performance Certificate (EPC) rating, or someone in your household receives qualifying benefits, you may be eligible for full funding under the ECO4 or GBIS government schemes.
Our team will assess your eligibility during your free home survey and handle all paperwork if you're approved.

Is the insulation material safe and breathable?

Yes. We use modern insulation materials that are not only BBA-certified for performance and safety but also breathable and moisture-regulating, which is especially important for older homes.
The materials are designed to prevent damp build-up and mould risks, ensuring your floors stay dry, and your indoor air quality remains healthy.
