Water Infrastructure Services for
UK Water Companies

We are a regular delivery partner for Affinity Water and Thames Water, handling repair and maintenance, main laying, leak detection, and metering work on their networks. We are accredited under WIAPS (Water Industry Approved Plumbers Scheme) and WIRS (Lloyd’s Register self-lay provider scheme).

We are WIRS accredited (self-lay provider via Lloyd’s Register), WIAPS approved, and hold ISO 9001, 14001, and 45001 for quality, environmental, and health and safety management. We are Constructionline Gold, Achilles-registered (ID 00019964), NRSWA accredited for highway works, and Cyber Essentials certified. Our field teams are CSCS cardholders and EUSR registered.

Yes. We run 24/7 standby crews for emergency burst mains, line stopping, and reactive repair work, seven days a week. We deliver within KPI on some of the most challenging repairs in the Affinity Water network, including complex deep repairs, concrete encapsulations, and large-diameter linestops.

Yes. We deliver multi-phase mains replacement, main laying, and leakage reduction programmes as a Tier 2 delivery partner to Tier 1 water company frameworks, as well as direct to the water company. Scale ranges from a single burst repair to multi-kilometre main laying and network-wide leakage reduction schemes.

From our Hertfordshire depot we cover Hertfordshire, London, Surrey, Essex, Cambridgeshire, and Berkshire as standard. For larger water company programmes we travel further across the South East and nationally, and we have satellite teams running out of Heathrow and Affinity Water depots at Rickmansworth and Staines.

Yes. We handle pipe bursting, slip lining, cut-and-replace rehabilitation, and lead pipe replacement work for ageing water networks. Much of this work is planned around AMP programme priorities and customer impact constraints. We self-deliver the full scope, from survey and design through to reinstatement and handover.

Yes. We regularly operate as a Tier 2 delivery partner for Tier 1 water company framework contractors. Our WIAPS and WIRS accreditations, ISO triple certification, Constructionline Gold status, and Achilles registration are all in place to integrate cleanly into Tier 1 procurement processes. We hold our own insurance, carry our own plant, and deliver full scope with our own teams.

Yes. We support Affinity Water’s AMP8 delivery through our repair and maintenance framework, and we deliver main laying, mains rehabilitation, leakage reduction, and metering work aligned to AMP8 capital programme priorities. We are set up to move on AMP8 workstreams at pace for water companies and Tier 1 delivery partners across the South East.

Yes. Our own field teams handle the full scope, from excavation and pipe laying through to chlorination, pressure testing, reinstatement, and final sign-off. One team, one point of contact, one set of accreditations. That removes the co-ordination risk and accountability gaps that come with stitching multiple subcontractors together on a water company scheme.

All our repair and maintenance work for Affinity Water is delivered against defined KPIs for response time, repair quality, customer impact, and sign-off. We have been delivering to water company specification for over 40 years and build our teams, scheduling, and paperwork around meeting those standards on every job.
