About Us

Your Trusted Whole-House Retrofit Specialists

Who We Are

BSM Energy was founded with a single purpose: to make homes warmer, more energy-efficient, and more comfortable for the people who live in them. Based in West Yorkshire, we work with homeowners, private landlords, and developers across the UK, delivering a fully joined-up retrofit service that covers every stage of the process.

From the initial whole-house assessment through to expert coordination and TrustMark-accredited installation, we manage everything in-house  so you always have one point of contact, complete transparency, and a result you can rely on.

Our Mission

Our mission is simple: to deliver retrofit solutions that genuinely make a difference. We believe every homeowner deserves access to expert energy advice and high-quality improvement works  carried out to the highest standards, with minimal disruption and maximum results.

Every project we undertake is fully compliant with PAS 2035, the UK's gold standard for whole-house retrofit. That means your property is surveyed, designed, installed, and signed off correctly  not just quickly.
