CTS provides review of EWS1/FRAEW outputs and coordination of accredited assessors for higher-risk buildings in London - independent, client-side, and acting solely for the building owner.
London carries the largest concentration of higher-risk buildings in the country, from residential towers in Tower Hamlets and Greenwich to mixed-use blocks in Southwark and Croydon.
As an independent, client-side advisor with no contractor or supplier affiliations, CTS provides review of EWS1/FRAEW outputs and coordination of accredited assessors, with findings recorded to a BSR-ready golden thread on the CTS BuildSafe platform.
As at 30 April 2026, 4,378 residential buildings 11m and over with unsafe cladding were being monitored in the government's remediation programmes across England - 55% had started or completed works and 35% were complete. London sits within one of the largest concentrations of these buildings in the country.
