Cambridgeshire has a water problem that most growth areas would not recognise: it is one of the driest counties in the country, and the pace of development around Cambridge has put water supply at the centre of the planning conversation. Every new scheme in the county needs its water infrastructure planned around scarcity, delivered to the standards of the local undertakers, Cambridge Water and Anglian Water, and connected without delay to programmes that are already under scrutiny.

Delivering that work falls to a relatively small pool of specialist contractors. The firms below are established water utility specialists either based in Cambridgeshire or serving the county as part of their core operating area.

McFadden Utilities

McFadden Utilities is a family-run water utility and civil engineering contractor based in Welwyn Garden City, Hertfordshire, serving Cambridgeshire as part of its operating area across the East of England and South East. Established in the early 1980s, the firm has over 40 years of experience in clean water infrastructure.

McFadden’s service range covers water mains installation, new water connections, WIRS-accredited self-lay water services, leak repair, and under-pressure drilling, with reinstatement, tarmac, and road surfacing delivered in house. The firm’s water company clients include Affinity Water and Thames Water, and it has delivered work on the Anglian Water network, the undertaker covering much of Cambridgeshire. McFadden also operates within the supply chains of Tier 1 contractors including Balfour Beatty and Skanska.

Accreditations include WIRS for self-lay water, ISO 9001, 14001, and 45001, Constructionline Gold, and Achilles UVDB Audited status, the standard procurement gateway for water sector work.

Ground Utilities

Ground Utilities is a multi-utility contractor based in Cottenham, just north of Cambridge, making it one of the few specialist utility firms headquartered in the county itself. The company delivers water installations alongside electricity, telecommunications, and renewable energy infrastructure, with CHAS accreditation and a project record that includes utility diversions and deep excavation work.

Dunore

Dunore is a water connections specialist based in Wollaston, Northamptonshire, serving the East of England including the Anglian region that covers Cambridgeshire. The firm focuses on new water connections and associated mains work, and carries an excellent customer record across its connection projects.

M&S Water Services

M&S Water Services is a self-lay provider based in Luton, operating across the Anglian Water and Affinity Water regions. The firm offers a complete self-lay package for developers, from assisting with the water company application through to commissioning the new main and completing the final service connections.

Choosing a water contractor in Cambridgeshire

The county’s combination of growth pressure and water scarcity makes contractor selection a genuine programme decision. Before appointing, check:

• Experience with the local undertakers. Cambridge Water and Anglian Water each have their own developer services processes, technical standards, and adoption requirements. The contractor should know them already.
• WIRS accreditation for self-lay schemes. If the development is taking the self-lay route, the provider must appear on the WIRS register administered by LRQA, and the accreditation scope must cover the works proposed.
• Capability across the whole job. Mains, connections, testing, chlorination, and reinstatement delivered by one firm means fewer interfaces, faster permit closure, and one point of responsibility.
• Procurement-grade accreditations. Achilles UVDB and ISO certification indicate a contractor that water companies and Tier 1 firms have already audited.

Water is the constraint shaping Cambridgeshire’s growth. The contractors who understand both the engineering and the local undertakers’ processes are the ones turning approved schemes into connected ones.
