Improving the energy efficiency of a listed building requires a non-invasive, expert approach. We begin with a professional PAS 2035 assessment to identify exactly where your property is losing heat, focusing on thermal bridging and air leakage. Unlike modern builds, heritage properties often feature solid stone walls that require vapour-permeable insulation systems to allow the structure to breathe. We install bespoke internal wall insulation and advanced loft upgrades that remain hidden behind traditional finishes, ensuring your home stays warm without altering its historical aesthetic.

We know that making changes to a listed building in Cowbridge involves navigating complex planning permissions and local authority conservation rules. Our team acts as your partner in this process, ensuring all work complies with the latest building regulations and MEES standards for landlords. By focusing on internal interventions such as targeted draughtproofing and thermal insulation, we often provide effective energy solutions that avoid the need for invasive external changes, keeping your property compliant and protected.

Choosing to upgrade your home with our team delivers long-term comfort and value. Beyond significantly lowering your winter energy costs, our insulation methods effectively combat condensation and black mould, which are common issues in older solid-wall properties. Furthermore, enhancing your EPC rating is essential for future-proofing your home against changing legislative standards. We provide SWIGA-backed insurance guarantees for our installations, offering you total peace of mind that your investment in your heritage property is secure and durable.

Insulation is only half the task when dealing with period interiors. To ensure your home retains its authentic look, we work closely with our sister company, Global Plastering. This partnership allows us to offer a complete end-to-end service, where we install high-performance insulation and finish with traditional lime plastering or period-appropriate wall treatments. Whether you need to restore a Victorian ceiling or match existing lath and plaster, our craftsmen deliver a flawless finish that respects the craftsmanship of your property.
