What Crayside Consulting does

Crayside Consulting is a UK-based multi-disciplinary design and survey consultancy that delivers engineering services to critical infrastructure clients. Founded in 2014 and headquartered in Basingstoke, Hampshire, the firm operates seven offices across the UK (Basingstoke, London, Ipswich, West Kingsdown, Poole, Bristol) and India (Ahmedabad), employing approximately 40 staff. Its service portfolio spans mechanical, electrical, and public health (MEP) design; civils and structural engineering; building information modelling (BIM); surveys and reporting; sustainability; and specialist earthing and lightning protection delivered through its wholly-owned subsidiary GreyMatters Global, acquired in 2023.

The company serves enterprise clients across five core verticals — Rail, Data Centres, Nuclear, Utilities, and Transport — with rail as the dominant segment, evidenced by 600+ rail infrastructure projects delivered and the recent SME Growth in Rail Award from the Railway Industry Association. Named clients include Network Rail, Greater Anglia, BAM Nuttall, Oxford University, Walker Construction, Biogen, Optilan, and South Western Railway. Underlying technology centres on BIM Level 2 processes using Autodesk Building Design Suites (AutoCAD/Revit MEP), Microstation, AecoSim, 3D laser scanning, and point cloud scanning integrated with REVIT modelling; specialist electromagnetic simulation is performed using CDEGS and XGSLab software through the GreyMatters subsidiary.

Crayside generates revenue through project-based professional services engagements, with 92% of revenue from repeat clients and 85% of projects delivered with Tier 1 contractors. Go-to-market relies on enterprise field sales, industry accreditations (RISQS, Constructionline GOLD, Achilles UVDB, ISO 9001/14001/45001, Cyber Essentials), industry body memberships (RIA, NIA, CIBSE), and professional networks rather than digital or self-serve channels. The firm has expanded through organic growth, an acquisition (GreyMatters Global, 2023), two new business unit launches (Architectural Technology, Environmental Services) in 2025, and senior hiring including four new director appointments over a 24-month period.

Broad incumbents

• AtkinsRéalis: Global engineering consultancy with a large UK rail, nuclear and infrastructure practice that competes for the same Network Rail frameworks and major project portfolios, though operating at materially larger scale and broader service breadth.
• Stantec: International engineering consultancy with significant UK rail, water/utilities and infrastructure practices, including the acquired Hydrock business. Competes for many of the same critical-infrastructure frameworks as Crayside.
• WSP: Global engineering professional services firm with a substantial UK rail, property and infrastructure business that targets the same Network Rail, TOC and nuclear clients as Crayside, with overlapping MEP, civils and BIM service lines.
• Arcadis: Global design and engineering consultancy with UK rail, nuclear and infrastructure operations that competes for the same public-sector and Tier 1 contractor work, though at materially greater scale.
• Mott MacDonald: UK-headquartered global engineering consultancy active across rail, nuclear, data centres and utilities — overlapping strongly with Crayside's vertical mix but competing at a significantly larger scale on framework bids.
