What is AMP8?

Asset Management Period 8 — The Biggest Water Investment in History

AMP8 runs from April 2025 to March 2030 and covers every water company in England, Wales, Scotland and Ireland. It was determined by Ofwat's PR24 process and represents more than double the investment of any previous AMP cycle.

For the first time, water companies face financial penalties if they miss AMP8 targets — which means procurement is moving faster, frameworks are opening earlier, and the supply chain is under pressure to respond at pace.

Storm overflow improvements. Lead pipe replacement. Treatment works upgrades. Network digitalisation. Smart metering. Every one of these programmes creates procurement opportunities for the supply chain — if you know where to look.

£14.5bn — Storm Overflow Improvements
14,187 overflow sites. Every one needs surveying, monitoring and many need upgrading. Creating major frameworks for civil, MEICA and environmental specialists.
£22bn — Water Supply & Treatment
New reservoirs, treatment works upgrades, PFAS removal and drinking water quality improvements driving major frameworks for treatment technology and construction specialists.
£12bn — Network Resilience & Leakage
Lead pipe replacement, mains renewal and smart metering programmes across all water companies. Steady pipeline of work for pipeline and civil engineering contractors.
£8bn — Digital & Data
SCADA upgrades, IoT sensor networks, digital twins, CWQM rollout and smart metering programmes. Major opportunity for technology and data specialists.

Frequently Asked Questions

AMP8 — Questions from the Supply Chain

Answers to the most common questions we receive from water sector suppliers, contractors, consultants and technology providers trying to understand the AMP8 procurement landscape.

What is AMP8 and when does it run?

AMP8 stands for Asset Management Period 8. It is the eighth five-year regulatory cycle for the water industry in England and Wales, running from 1 April 2025 to 31 March 2030. The investment programme — totalling approximately £104 billion — was determined by Ofwat's Price Review 2024 (PR24) process. It is the largest water infrastructure investment programme ever undertaken in the United Kingdom, representing more than double the investment of any previous AMP cycle. Scotland (Scottish Water) and Northern Ireland (NI Water) operate under equivalent regulatory frameworks set by the Water Industry Commission for Scotland and the Utility Regulator NI respectively.

Why is AMP8 so much larger than previous cycles?

Several converging pressures have driven the scale of AMP8 investment. The Environment Act 2021 introduced legally binding storm overflow reduction targets — requiring water companies to reduce combined sewer overflow (CSO) spills by 40% by 2030 and 80% by 2045. The Drinking Water Inspectorate (DWI) has tightened compliance requirements around PFAS, lead, nitrates and emerging contaminants. Ofwat's new customer performance commitments attach financial penalties to failure. On top of this, significant infrastructure — treatment works, mains networks, pumping stations — that was last renewed in the 1970s and 1980s is now reaching end of life. The convergence of environmental regulation, asset age, and new statutory obligations has produced a procurement programme without modern precedent in UK water.

How does the supply chain access AMP8 frameworks?

Most AMP8 capital investment is delivered through established framework contracts rather than individual tenders. Water companies procure a panel of pre-qualified contractors and consultants at the start of a regulatory period, then call-off work against those frameworks throughout AMP8. To participate, suppliers must either be on an existing framework (awarded 2024–2025) or wait for the next call-off or framework renewal. For suppliers not on a framework, the best approach is to target Tier 2 and Tier 3 subcontracting opportunities — which require building direct relationships with framework holders. Water Industry Hub tracks both frameworks and subcontracting pipeline to give the full supply chain picture.

What is PR24 and how does it relate to AMP8?

PR24 is Ofwat's Price Review 2024 — the regulatory process that determined customer bills and allowable investment for AMP8. Ofwat published its Final Determination in December 2024, setting individual company-level investment allowances and performance commitments. Five companies — Southern Water, Thames Water, South East Water, Affinity Water and Bristol Water — referred Ofwat's determination to the Competition and Markets Authority (CMA) for redetermination. The CMA issued its final decisions in March 2026. For the supply chain, the key implication is that all 17 Ofwat-licensed companies now have confirmed investment envelopes, meaning procurement plans are fixed and framework awards are proceeding at pace.

Which water companies offer the largest supply chain opportunity in AMP8?

By total investment envelope, the largest AMP8 programmes are Thames Water (c.£18.7bn), Anglian Water (c.£11.6bn), United Utilities (c.£13.7bn), Severn Trent (c.£12.9bn) and Yorkshire Water (c.£8.5bn). However, investment scale alone doesn't determine supply chain accessibility. Companies with open, competitive procurement processes and active Tier 2/3 pipelines often offer better opportunities for smaller suppliers than the largest operators who concentrate work with a small number of Tier 1 partners. Water Industry Hub profiles the procurement approach for all 17 Ofwat-licensed operators alongside Scottish Water and NI Water.

What supply chain categories are seeing the most procurement activity in 2025–2026?

The most active procurement categories in the first year of AMP8 are: civil engineering and infrastructure (driven by storm overflow and mains renewal programmes); MEICA (mechanical, electrical, instrumentation, control and automation — driven by treatment works upgrades and pumping station replacements); smart metering and IoT (led by South East Water's 900,000-meter rollout and similar programmes at Affinity, Portsmouth and Bristol Water); continuous water quality monitoring (CWQM) under Section 82 of the Water Industry Act; and environmental services (ecological surveys, catchment management, WINEP compliance). Demand for PFAS treatment technology is also growing rapidly following new DWI guidance issued in late 2024.

What accreditations do I need to work in the water sector?

Water sector procurement typically requires specific quality and safety accreditations beyond standard ISO certifications. The most commonly required are WIRS (Water Industry Registration Scheme) for water mains activities, WIRSAE for water mains activities on assets up to 90mm diameter, WIAPS for connections, UVDB (now Achilles Water) for broader supply chain registration, and Constructionline or equivalent for civil contractors. Some water companies also require sector-specific health and safety schemes including CHAS, SafeContractor or Acclaim. Specific requirements vary by water company and contract type. Water Industry Hub's accreditation guide covers all major water sector schemes with registration links.

How does Water Industry Hub track AMP8 procurement?

Water Industry Hub monitors all 22 UK and Ireland water sector procurement portals on a daily basis, including Find a Tender, Jaggaer, In-Tend, Bravo Solutions, Delta eSourcing, and company-specific portals. We also track Procurement Act 2023 pipeline notices, which water companies are now required to publish annually. Contract award notices are reviewed to build a forward pipeline based on contract end dates — allowing us to predict framework renewals 12–24 months in advance. This intelligence is supplemented by direct market knowledge from 18 years of water industry experience, industry events, pre-market engagement sessions, and supply chain briefings published by major operators. The result is the most comprehensive forward procurement picture available for the UK water sector supply chain.
