MCS is the UK’s quality mark for renewable energy technologies, playing a vital role in certifying a wide range of products essential for every installation carried out by every certified installer.

With millions of MCS certified installations across the UK and demand continuing to rise, MCS products, certified against MCS Standards, ensure installations are high-quality, efficient, and safe.

MCS product certification is a trusted quality mark that assures consumers and installers of the efficiency, durability, and safety of small-scale renewable technologies. It guarantees compliance with UK regulations and helps manufacturers position their products as leaders in the industry.

MCS certification is often required for access to government incentives and schemes like the Boiler Upgrade Scheme (BUS), providing financial support for renewable energy technologies.

MCS sets the standards for the UK marketplace but for technologies such as solar heating and heat pumps, we recognise some other non-UK product certification schemes as equivalent.
