This briefing explains why AMP8 is a defining investment cycle for the UK water sector and why delivery risk will matter as much as ambition. We summarise who is impacted (companies, supply chain, customers), what’s driving the scale-up, and the economic and environmental trade-offs that will shape outcomes from 2025 to 2030.
Ofwat’s AMP8 final determination for 2025–2030 approves £104bn of expenditure, described as the largest investment programme since privatisation. The paper reviews stakeholder impacts (including financing needs for companies and capacity pressures for contractors), customer bill implications, and macroeconomic effects such as employment and inflationary pressures. It identifies procurement constraints (skills gaps and carbon-intensive materials), summarises environmental objectives (including storm overflow reduction and biodiversity net gain), and closes with key milestones and implementation risks across the AMP8 period.
Ofwat's final determination for the 2025–2030 period (AMP8) approves a totalexpenditure of £104 billion, marking the largest investment programme sinceprivatisation.
Water Companies
• Opportunities: Access to increased funding facilitates infrastructure upgrades and service improvements.
• Risks: Companies are expected to raise over £7 billion in equity to support their investment programmes, posing challenges in securing necessary financing.
For companies to raise this level of debt, it is important that they maintain resilient financial structures. In their representations, companies forecast a need to raise over £7 billion of equity to support their investment programmes. Some companies additionally proposed to restrict dividends, to support delivery of investment. We expect companies will need to revisit their financing plans for the 2025-30 period now they have the certainty of our final decisions. In some cases, companies will need to take steps to strengthen their levels of financial resilience.
• Opportunities: The surge in projects offers growth prospects for contractorsand suppliers.
• Risks: Potential bottlenecks due to labor shortages and material supplyconstraints may affect project timelines.
• Opportunities: Anticipated improvements in water quality and servicereliability.
• Risks: Average household (water and sewerage) bills are forecast to rise byalmost £250 over the next five years, a 51% increase, reaching £730 by 2030.ofwat
• Employment: The investment is expected to create over 30,000 new jobs and 4,000 apprenticeships across the UK.
• Regional Development: Infrastructure projects are anticipated to stimulate economic growth in various regions.
• Inflationary Pressures: Increased demand for materials and labor may contribute to inflation in the construction sector. Procurement Challenges – Engineering Labour, Carbon-Intensive Materials.
• Labour Shortages: The sector faces a significant skills gap, with an estimated need for 100,000 new operatives by 2030. causeway.com
• Material Supply: High demand for carbon-intensive materials like concrete and steel may lead to supply constraints and increased costs
I was delighted that MCC's work was completed on time, and within budget, helping us deliver important changes and improvements, to the benefit of our stakeholders. MCC's report is published on the CCC website.
I am delighted to recommend MCC Economics. Specifically, I worked closely with PJ, who helped us with our Nuclear and CCUS projects. PJ helped us develop new policies and answer questions from our stakeholders. His support helped us deliver important changes and improvements, to the benefit of our stakeholders.
MCC Economics has helped us better understand the most important issues for our stakeholders, including: charges, shareholder returns, debt payments and inflation impacts.
I am delighted to recommend PJ and his team at MCC Economics. We've been working together on National Policy Statements to help meet net zero targets for 2030 and 2050. We initially appointed MCC Economics to support us on offshore wind consultation analysis and have recently reappointed MCC Economics to undertake a larger consultation analysis role across all sectors, including hydrogen, CCUS and networks. I can confirm that PJ and his team have shown excellent spreadsheet skills, alongside very good project management, planning and analysis skills, helping us deliver important changes, and continuous improvements, to the benefit of our stakeholders.
I am delighted to recommend PJ and his team from MCC Economics. They helped us with our price controls for Heathrow airport and for NATS (En Route) plc (the air traffic services provider). Specifically, the MCC team helped us deliver important changes and improvements to our financial models and supporting policy documents, to the benefit of our stakeholders.
I am delighted to confirm that I worked with PJ on a retail project in 2015. The project helped stakeholders understand electricity costs and charges. Specifically, the project helped us explain to stakeholders, internally and externally, why electricity charges differed across the regions (GB, NI & Ireland). PJ was a key member on the project team, which helped deliver changes and improvements in the understanding of energy retail.
