TRANSFORM YOUR LOFT / LOFT INSULATION FITTERS

Loft Insulation Installers

Use our professional loft insulation installers to boost your home’s warmth, energy efficiency and comfort. When insulation is insufficient, a large share of a home’s heat escapes through the roof, reducing its ability to stay warm. Bringing insulation up to the recommended depth helps your home hold onto its heat far more effectively.

Glass Mineral Wool Loft Insulation

Glass Mineral Wool is the recommended loft insulation choice of our loft insulation installers thanks to its excellent performance, sustainability and comfort. Homes without sufficient insulation can lose up to 25 percent of their heat through the roof, which is why our loft insulation fitters install our insulation to a depth of 270 mm wherever possible. This helps your home hold onto its warmth, support better energy efficiency and feel more comfortable in every season. 

Made from non-combustible glass mineral wool with up to 80 percent recycled content, it is manufactured using innovative ECOSE® Technology for a greener home and delivers strong insulation without the itchiness associated with traditional materials, making it a more pleasant and modern solution for your loft. 

Thicknesses available:
100 mm | 170 mm | 270 mm

Loft Insulation FAQs

A significant amount of heat can escape through the roof if insulation is missing or too thin. Upgrading your loft insulation helps your home retain warmth more effectively, improving comfort and reducing unnecessary heat loss.

Our surveyors check the depth and condition of your current insulation during your appointment. Many homes fall short of the recommended 270 mm, especially in older properties or lofts where loft insulation has been disturbed or compressed.

We use Glass Mineral Wool, a high-performance, non-combustible insulation made with up to 80% recycled content. It is manufactured using ECOSE® Technology and is designed to be non-itchy, lightweight and long-lasting.

Yes. Increasing your loft insulation depth helps your home hold onto heat for longer, making it easier to keep your living spaces comfortable.

<span style=”font-weight: 300;”>Under UK Building Regulations (Part L), most lofts require insulation with a total thickness of 270mm to 300mm (when using standard mineral wool) to achieve the required thermal efficiency. If you are renovating more than 25% of your roof, you are legally obligated to upgrade to this standard. To stay compliant and prevent dampness, you must leave a 50mm ventilation gap at the edges (eaves) and avoid squashing the material with boards or heavy storage, as compression ruins its effectiveness.</span>

Not at all. When installed alongside a raised loft boarding system, the insulation remains uncompressed and able to perform correctly. This creates a safe, efficient combination for both energy performance and storage

Yes. You can choose insulation as a standalone upgrade, or combine it with loft boarding, shelving or loft lighting as part of a full loft improvement.

Yes. This insulation is non-combustible with an A1 Euroclass fire rating and contains no added formaldehyde. It is designed for safety, comfort and improved indoor performance.

Most insulation installs or top-ups can be completed in a single visit, depending on loft size and access. Your surveyor can give you a clear timeline during your appointment.

<span style=”font-weight: 300;”>The cost for your loft insulation fitting will depend on the size of your installation. Our team of loft insulation fitters will guide you through the costs before any work is agreed.</span>

Yes, you may be eligible for free or subsidised insulation through government schemes like the Warm Homes Plan or ECO4. Funding is primarily aimed at households with a low income, those receiving certain benefits, or homes with a poor energy rating (EPC D or lower) in lower Council Tax bands. To qualify for a loft “top-up,” most schemes require your current insulation to be 100mm or less. You can check eligibility through your energy supplier or by contacting your local council to see if you qualify for help with installation costs.

If you have items stored in your loft, we ask that the space is cleared before installation. Your surveyor will let you know what needs to be removed and if there are any exceptions.
