Roof Insulation Lymington

Many properties across Lymington, Buckland, Everton, Keyhaven, Milford on Sea, Pennington, and Woodside were built when roof insulation standards were minimal or non-existent. Even homes that do have some loft insulation often fall short of the current 270mm UK minimum requirement. Inadequate roof insulation means higher heating bills, uneven room temperatures, and a lower EPC rating. Upgrading to properly installed 300mm insulation addresses all of these issues and can deliver annual savings of £200 to £400 on your energy bills. Whether you live in a period property in the town centre or a coastal home in Keyhaven, professional roof insulation is one of the smartest investments you can make in your property.

Knauf Earthwool is a trusted mineral wool insulation that we install to a full 300mm depth, exceeding the 270mm UK building regulations minimum. It is laid between and over the ceiling joists in your loft space, creating a continuous thermal barrier that dramatically reduces heat loss through the roof. Knauf Earthwool is non-combustible, does not absorb moisture, and maintains its performance for decades. It is the ideal choice for most Lymington properties with standard loft access and joist depth. Typical installation costs for Knauf Earthwool range from £900 to £1,200, and every installation is backed by manufacturer warranties of 10 to 25 years alongside our own workmanship guarantee.

Superfoil is a high-performance reflective multifoil insulation that is particularly well suited to older properties around Lymington where rafter depth is limited. Unlike bulky mineral wool, Superfoil achieves excellent thermal performance in a thin profile by reflecting radiant heat back into the living space. This makes it an excellent solution for period properties in the town centre and character homes in Pennington and Milford on Sea where maintaining roof headroom is important. Superfoil installations typically cost between £1,200 and £1,800, and come with manufacturer warranties of 10 to 25 years. We do not install spray foam insulation — we specialise in its removal — so you can be confident that we will recommend only proven, regulation-compliant products for your home.

All roof insulation work in the UK must comply with Part L of the Building Regulations, which sets minimum standards for energy efficiency. We handle the entire building regulations process on your behalf, from initial notification through to final certification. This means you do not need to arrange your own building control inspections or worry about compliance paperwork. Our three-stage process covers survey and planning, installation and inspection, and final certification, ensuring everything is completed correctly and documented. For cold roof installations, we ensure 25mm eaves ventilation is maintained to prevent condensation problems. At the end of every job, you receive full certification confirming your installation meets current standards.

Every roof insulation installation we carry out in the Lymington area is protected by comprehensive warranty cover. You receive both a workmanship warranty from us, covering the quality of the installation itself for 10 to 25 years, and a separate manufacturer warranty from either Knauf or Superfoil covering the product for 10 to 25 years. This dual layer of protection gives you complete peace of mind that your investment is safeguarded for the long term. We also provide full cleanup after every installation, leaving your loft space tidy and your home exactly as we found it.
