What Clifford Devlin does
Clifford Devlin is a UK-based specialist construction services contractor providing asbestos removal, demolition, refurbishment and fit-out, fire protection, and construction/electrical/mechanical services. Established in March 1962 and headquartered in Grays, Essex (relocated from Bow in June 2021), the company operates from a purpose-built facility and a licensed waste transfer station in Bow capable of processing up to 32 cubic metres of asbestos waste per day. Its service portfolio is delivered through coordinated specialist divisions and supported by purpose-built assets including air-tight Ford Transit transport vehicles and mobile decontamination units with integrated welfare facilities. The company is governed by an integrated management system combining ISO 9001, ISO 14001, and OHSAS 18001 standards for quality, environmental, and occupational health and safety management.
The company's go-to-market is a direct B2B motion targeting UK public sector buyers (local authorities, NHS trusts, housing associations) and private developers through appointed procurement frameworks — including Bloom/NEPRO³, CHIC DPS, ProcurePublic Demolition Framework, and ProcurePublic Building Refurbishment Framework — alongside direct contracts with tier-one contractors such as Costain (HS2 enabling works at Euston, Tottenham Court Road redevelopment, Newbury) and Laing O'Rourke. Revenue is generated project-by-project on a quote basis from clients such as Maldon District Council, Guys and St Thomas' NHS Foundation Trust, Landsec, Morley Fund Management, and City of London Authority/Costain plc. Clifford Devlin transitioned from a privately-owned family business to employee ownership through an Employee Ownership Trust in February 2022, with shares now held by employees and oversight exercised via an EOT Board.
