For solid-walled homes in Ystradgynlais, there are two primary ways to stop heat loss: External Wall Insulation (EWI) and Internal Wall Insulation (IWI). EWI involves fixing insulating material to the outside of your property, which is then covered with a protective render or cladding. This not only keeps the heat in but also refreshes the aesthetic of your home. If you prefer to keep the exterior character of your house, IWI is the alternative. We fit insulation boards to the interior walls, which our sister company, Global Plastering, then finishes to a professional standard. Both methods effectively solve thermal bridging issues, keeping your home warm and dry.

Improving your home energy efficiency is one of the most effective ways to combat fuel poverty and reduce your carbon footprint. A property with poor thermal performance often suffers from condensation, which can lead to black mould growth—a major concern for health and property maintenance. By upgrading to a modern insulation system, you significantly improve your EPC rating, which is essential for landlords needing to meet current MEES compliance standards. Our retrofit assessments identify exactly where your home is losing heat, allowing us to implement a targeted strategy that saves you money long-term.

We pride ourselves on being fully PAS 2030 compliant and PAS 2035 accredited, ensuring that every project meets the highest industry standards for whole-house retrofits.
