Briggs Amasco

What Briggs Amasco does

Briggs Amasco Ltd is a UK private-limited commercial roofing and waterproofing contractor, founded by William Briggs in 1865 and operating today as a wholly-owned subsidiary of the international IKO Group, one of the world's largest waterproofing manufacturers. From its headquarters in Cradley Heath, West Midlands, and a network of 11 branches spanning Aberdeen, Birmingham, Chessington, Glasgow, Hull, Leeds, London (Harold Wood), Manchester, Newcastle (South Shields) and others, the company delivers more than 800 projects per year — ranging from small refurbishments to multi-million-pound contracts for commercial, public-sector, education, healthcare, rail and heritage clients such as Mace (Battersea Power Station Phase Two, 5 Broadgate), Network Rail (Birmingham Gateway), the NHS, and McDonald's.

The company's core technology stack comprises six specialist waterproofing and roofing systems: Mastic Asphalt, Reinforced Bituminous Membrane (RBM), Single Ply (PVC/TPE and EPDM), Hot Melt, Cold Liquid polyurethane coatings, and Green Roofs. These are layered over in-house industrial assets — a state-of-the-art asphalt finishing machine operating five times faster than hand lay at lower temperatures, an electric plant fleet (replacing LPG-fired melters with a 65% CO2 reduction), super-slim PIR/VIP insulation panels with lambda 0.006 W/mK developed with insulation partners, and bespoke app-based safety observation reporting. Because the firm installs proprietary IKO membranes (Permatec, Permapark, Permaphalt, enertherm), it operates a vertically integrated installer-manufacturer model.

Commercially, the firm sells project-based, quote-driven roofing and waterproofing contracts won via an enterprise field-sales motion executed through its 11-branch national network; each branch handles surveying, estimating, contract management, and CAD-enabled design. All operatives are directly employed and trained internally, supported by four full-time safety advisors and a formal apprenticeship programme of 18 trainees. Revenue is not publicly disclosed; the firm holds ISO 9001/14001/45001, Achilles Level 5, Constructionline Gold, NFRC, MAC, SPRA, GRO, Investors in People, and Cyber Essentials Plus certifications, and was the first UK roofing/waterproofing contractor to commit to SBTi targets and to achieve Carbon Literate Organisation status.
