Stroma is the UK’s leading provider of technology-driven safety, sustainability and compliance services to clients across all stages of the building lifecycle, from pre-construction through to occupancy. Its services include testing, consultancy and building control, along with inspection and maintenance work.

As part of its testing and consultancy work, it helps customers from multi-national corporations to SMEs on their journey to becoming net zero through increasing energy efficiency and reducing CO2 emissions and wastage.

Investing for impact

Since LDC invested in Stroma in 2014, the business has expanded its range of sustainability services in design and consultancy to become a leading provider to the built environment industry. It is currently in the advanced stages of the B-Corporation certification process.

LDC also supported Stroma to acquire three building control businesses which further strengthened its inspection and compliance offering. Over the period of LDC’s partnership, the business has delivered award-winning training programmes to around 2,500 professionals, guiding the next generation of building control specialists in the industry. Today, Stroma employs 350 people across its 14 regional offices which include sites in Cannock, London, Maidstone and Truro.

Martin Holt, CEO of Stroma, said: “Stroma’s core purpose of providing safety, sustainability and compliance service within the built environment has been developed with the full support of the LDC team.”

Through its extensive network, Phenna Group is now supporting Stroma to further expand its customer base and enhance its portfolio of market-leading services.
