Keep the warmth where it belongs — inside your home. Underfloor insulation is a highly effective way to prevent heat loss through the ground floor, especially in older properties with suspended floors.

Stay Warmer. Save Energy. Reduce Bills.

Underfloor insulation is one of the most effective yet often overlooked ways to improve a home’s energy efficiency. In properties with suspended timber floors, a significant amount of heat can escape through gaps and uninsulated floorboards, leading to colder rooms and higher heating costs. At Giant Source, we help you combat this problem with professionally installed underfloor insulation — completely free if you qualify under the ECO4 scheme.

Why Underfloor Insulation?

• Prevent Heat Loss: A well-insulated floor helps retain warmth, meaning your heating system doesn’t have to work as hard to keep your home comfortable.

• Lower Energy Bills: Reducing heat loss directly translates to lower heating costs — saving you money year-round.

• Enhanced Comfort: Say goodbye to chilly floors and cold drafts, especially during the winter months.

• Eco-Friendly: Using less energy not only saves money but also reduces your household’s carbon footprint.

• Improved EPC Rating: Boost the energy performance of your home, increasing its value and efficiency.

How It Works

Our team begins with a full home assessment to determine if your property is suitable for underfloor insulation. This service is typically available for homes with suspended timber floors (commonly found in pre-1970s properties). Once approved, our insured and qualified installers carefully fit insulation materials beneath your floorboards without causing major disruption to your living space.

Covered by the ECO4 Scheme

Thanks to government funding under the ECO4 scheme, underfloor insulation can be provided at no cost to you. This initiative is designed to help eligible households reduce energy waste, improve home comfort, and combat fuel poverty — all while supporting the UK’s commitment to a greener future.
