Client Brief: The owners of this 1950s end-of-terrace property in Chessington were preparing the home for the rental market. With poor insulation and solid external walls, the property was expensive to heat and failed to meet the EPC requirements for private lettings. The client wanted to upgrade the property’s energy performance without compromising the original brick appearance. Our Solution: Home Improvements & Construction Ltd installed a full external wall insulation system using 110mm insulation boards. To maintain the character of the home and meet planning preferences, we finished the project with a premium brick-slip render system. This provided the visual effect of a traditional brick façade while delivering modern thermal benefits. We assisted the client in applying for local energy retrofit funding and provided full documentation, including before-and-after EPC assessments, compliance certificates, and detailed U-value calculations. The installation was managed entirely by our in-house team, including scaffolding, waste removal, and access coordination. Outcome: The property achieved an EPC rating of C, which met all current standards for rental properties. Heating and hot water energy usage was significantly reduced, making the home more attractive and cost-effective for tenants. The brick-slip finish matched the neighbouring homes so closely that passersby were unaware any insulation work had taken place. The project was delivered on time and within the agreed budget, providing long-term energy savings and visual continuity for the neighbourhood. Client Feedback: “HICL delivered exactly what we needed. The finish is indistinguishable from the original brickwork, and the insulation has made a huge difference in comfort and compliance. The whole process was smooth and professionally managed. I would absolutely recommend HICL for external wall insulation in Chessington.” This energy retrofit in Chessington shows how external wall insulation can meet modern efficiency standards without compromising a property’s original charm.
