30 Second Briefing
South West Water has extended Kier’s Network Services Alliance contract by two years, worth about £140m, to continue reactive and planned maintenance, leakage activity, network reliability schemes, metering and developer services across its network. Over the past year Kier has delivered more than 25,000 repair and maintenance jobs, including over 18,000 leak repairs and 32,000 metering optant and maintenance jobs, with over 97% of priority jobs attended within the two-hour target and average peak response around one hour. The deal secures workload into AMP8 and reinforces Kier’s water portfolio alongside Anglian Water, Severn Trent, Southern Water, Thames Water, United Utilities and Yorkshire Water.
Technical Brief
- Scope explicitly includes continued rollout of smart metering across the region’s potable water network.
- Contract covers both reactive and planned maintenance, plus network reliability schemes and developer services interfaces.
- Leakage activity is retained as a discrete workstream, supporting pressure management and burst response optimisation.
- Local supply chain participation is embedded in the agreement, supporting regional contractor and materials spend.
- Skills development in the South West is identified as a formal outcome alongside service delivery.
Our Take
South West Water has recently featured in our database both for a major Cryptosporidium incident and for rolling out continuous water quality monitoring with Galliford Try, so extending Kier on the Network Services Alliance signals the utility is doubling down on operational resilience and response capability alongside quality upgrades.
The AMP8 framework already includes Trant Engineering’s five‑year Amplify contract with South West Water, and this two‑year extension for Kier suggests SWW is favouring a stable core of repeat contractors in the South West rather than rebidding large network packages mid‑period.
