About Us

At KSDL, we believe every home should be warmer, healthier, and more energy efficient. We specialise in delivering retrofit and energy efficiency improvements that not only cut carbon emissions but also help households save money on their energy bills. 

With a team of accredited surveyors, coordinators, and installers, we provide a complete service – from free home surveys and tailored proposals through to high-quality installations. Our work covers insulation, heating upgrades, smart controls, ventilation and we are a PAS-accredited business. 

We are fully committed to government-backed funding programmes such as the ECO scheme and operate in line with PAS 2030/2035 standards, giving our customers confidence that every project is carried out to the highest level of compliance and quality.

Our mission is simple: to support households in reducing energy use, lowering carbon emissions, and improving comfort – step by step. Whether you’re looking to make small changes or carry out a full home retrofit, we’re here to guide you through the process.

Because carbon reduction matters – and your home deserves it.
