What ONE MEP does
ONE MEP Ltd. is a London-based, privately held mechanical, electrical, and public health (MEP) building services contractor founded in 2022 and registered in England as One MEP Ltd. (company number 14442153). The company delivers design, supply, installation, and commissioning of mechanical, electrical, public health, fire and security, HVAC, capital plant replacement, facilities management, and temporary site services for commercial, hotel, residential, mixed-use, education, senior living, and student accommodation projects in London and surrounding areas. Project values range from £0.5 million to £7.5 million on standard work, with disclosed single-project values reaching £10.5 million (40 Broadway) and £13 million (Lincoln's Inn Fields Phase 1).
The underlying technology is conventional UK MEP contracting rather than a software or product platform. Differentiation rests on integrated design practices, value engineering, and a sustainability-led approach demonstrated by BREEAM ratings up to Outstanding (The Burlian), WiredScore Platinum, and Well Platinum certifications on delivered projects, plus a 68% CO2 reduction at Knight's Village Warwick Castle. Core certifications include NIC EIC approved contractor, F-Gas, and Safecontractor status, with documented compliance under the UK Modern Slavery Act 2015. The leadership team comprises industry veterans with 15-37 years of UK building-services experience spanning landmark projects such as The Shard, the V&A Museum, Regent's Crescent, and the London Underground Framework.
Revenue is generated through project-based contracts (design-to-completion) plus recurring facilities management and maintenance work. Pricing is quote-based and not publicly disclosed. Go-to-market is enterprise field sales, secured primarily through repeat main-contractor partnerships (notably RED Construction Group) and direct relationships with property developers, hotel operators, councils, housing associations, and facilities managers (JLL, CBRE, Savills, Polytech FM). The firm has no external institutional funding, no parent company, and is wholly owned and controlled by its founders, with growth funded organically from project cash flows.
