CGP | MEP Ltd

What CGP | MEP Ltd does

CGP | MEP Ltd is a UK private limited building services design consultancy founded in 2014 by Mike and Ben in London (originally as CallaghanGreen, rebranded to CGP|MEP Ltd in 2019 to represent all three directors). The firm provides mechanical, electrical, and public health (MEP) design services across the full RIBA Stages 1-7 lifecycle, from concept design through to construction monitoring, and operates across education, leisure/sport/hospitality, residential and student accommodation, retail and commercial, high-rise residential, industrial, and Public Sector Decarbonisation Scheme (PSDS) retrofit projects for both public and private sector clients.

Its technical stack centres on Revit MEP delivered to BIM Level 2 maturity, with COBie data output, SBEM and EPC energy performance assessments, BREEAM Excellent/Very Good certification support, and an in-house Energy & Sustainability function covering thermal modelling, overheating analysis, daylight/ROL modelling, and pedestrian comfort assessments. The firm holds ISO 9001 (quality), ISO 14001 (environmental), and ISO 45001 (OH&S) certifications from NQA, and supports modern methods of construction including volumetric modular build, demonstrated on projects such as Chapter Lewisham (50% uplift in student bed spaces via modular construction).

Commercially, CGP MEP earns project-based consultancy fees negotiated per assignment (typically multi-year contracts), winning work through direct developer appointments (e.g., RED Group on Lewisham Exchange), main-contractor novations (ISG, T Clarke), and framework appointments (UK Leisure Framework with Alliance Leisure). Notable clients include the Department for Education, Harrogate Borough Council, West Midlands Police, JD Wetherspoon, Keele University, and Alliance Leisure. The firm is headquartered in Leeds (Royal House, Sovereign Street) with a London office at Moorgate (EC2R 6LL), serving projects across England, Wales, and occasionally Dublin. It is self-funded with no venture capital, private equity, or public-market exposure, and ownership appears concentrated among the founding directors.
