Retrofitting a listed building is not just about adding insulation; it is about managing moisture movement and protecting the structure for future generations. We operate as a PAS 2030 accredited team, strictly following PAS 2035 whole-house retrofit standards to ensure every installation is safe and effective. By focusing on breathable insulation systems, we address thermal bridging and prevent the common issues of damp and condensation that often plague traditional stone or solid-wall constructions in our area. Our approach ensures your property remains comfortable throughout the winter while meeting modern energy efficiency requirements.

We take a careful, diagnostic approach to every project. Our specialists begin with a professional retrofit assessment to identify exactly where your home is losing heat. Once we understand the specific needs of your building, we install bespoke insulation, such as high-performance internal wall insulation, which is specifically designed for heritage builds. Because we prioritise breathable materials, we ensure that the building continues to regulate moisture naturally. This keeps your home warmer, improves your EPC rating, and safeguards the building fabric from long-term damage.

One of the benefits of working with us is our ability to manage the entire process from initial assessment to the final decorative finish. While Global Energy Insulation focuses on the technical thermal upgrades and PAS 2035 compliance, our sister company, Global Plastering, handles all traditional internal finishes. This means you do not need to coordinate multiple contractors. We provide a complete end-to-end service, ensuring that once your insulation is installed, your walls are expertly plastered and restored to their original beauty.

Navigating the regulations for Grade I or II listed properties can be complex, especially when dealing with local planning authorities in Rhondda Cynon Taf. We handle the technical compliance for you, ensuring that all our work aligns with both building regulations and conservation area guidelines. As a SWIGA-backed and CHAS-accredited firm, we offer the professional reassurance you need. We are fully insured and hold a valid waste carriers licence, meaning every stage of our work is carried out to the highest standard of professional accountability.
