Dempsey Dyer


Since 1977, Dempsey Dyer have been manufacturers of high quality windows and doors. Over their many years of trading, they have sought to offer the most comprehensive product range available under one roof in the fenestration industry. Serving both the trade and commercial sectors with their supply of timber, uPVC, aluminium and composite products. Their product line includes a range of timber profiles manufactured at their own UK headquarters in West Yorkshire including Deceuninck uPVC profile systems, Reynaers aluminium profile systems and composite panels from the likes of Solidor.

As Dempsey Dyer often form part of a wider supply chain, it is vital they have stringent environmental policies in place as this is often analysed by potential clients. After exploring various options to bolster their green credentials, the installation of a commercial solar energy system was the next stage to reduce their carbon footprint. Centreco analysed Dempsey Dyer’s electricity usage profile and available roof space, and designed and installed a bespoke 208kW Roof Mounted Tier One Solar Energy System. This specification of system was selected based on providing the best long term commercial results for Dempsey Dyer.
