What Desco (design & consultancy) Ltd does

Desco (Design & Consultancy) Ltd is a UK-based Mechanical, Electrical and Plumbing (MEP) consulting engineering practice established in 1998 and headquartered in Sunderland, Tyne and Wear. The firm delivers mechanical and electrical design, advisory and consulting, environmental services, sustainable engineering (including net zero carbon design), water design (pool water filtration), and fire engineering across 13+ sectors including healthcare, education, industrial and energy, mission critical, retail, transport and infrastructure, commercial office, and public buildings. Its technical toolkit centres on BIM/Revit modelling (delivered to BSRIA BG6 stage 4A), IES thermal modelling for energy and carbon analysis, and an ISO 9001:2015-certified Quality Management System covering design, pool water services, building physics, and construction supervision.

The company operates through 16+ offices across the UK (including Leeds, Manchester, London, Croydon, Swindon, Edinburgh, Cambridge, Birmingham, Exeter, Luton, Nottingham, Wakefield, Mold, Takeley, and Swanbourne) plus a Philippines office in Makati City, sharing contact infrastructure with Pell Frischmann as part of the same corporate group. Desco is a subsidiary of Pell Frischmann Group, which sits under RSBG SE — the patient-capital investment arm of RAG-Stiftung, a German foundation tasked with managing environmental and social commitments from Germany's hard-coal mining closure. The parent group added Alfatech and Dorsch in 2023 to strengthen Mission Critical capabilities globally.

Desco generates revenue through project-based professional service fees on B2B engagements, secured via direct enterprise sales, framework agreements (NEUPC, NHS Shared Business Services HPCCAS), and embedded roles within design-and-build teams of major UK contractors including Wates Construction, Galliford Try, Balfour Beatty, and Sir Robert McAlpine. Pricing is quote-based per project scope and not publicly disclosed. The firm is privately held, has no subsidiaries, and operates with 101-250 employees. Notable engagements span Nissan UK battery plants, the IAMP £500m industrial JV, AESC UK Gigafactory, Teesside University's Digital Life (£40m), Newcastle Civic Centre refurbishment (£22m), Crowne Plaza Stephenson Quarter (£30m), Proton Partners' cancer treatment centres, and Eldon Square (£200m regeneration), with a 25+ year award track record across RIBA, RICS, BCO, and Constructing Excellence awards.
