IN Brief:
- The proposed frameworks could support up to £25bn of capital delivery over eight to 15 years.
- Procurement will cover AMP9, AMP10, and AMP11, alongside a separate design services competition.
- Market engagement will begin before formal procurement starts in early 2027.
Severn Trent is preparing to engage contractors, designers, specialists, and regional suppliers over capital-delivery frameworks potentially worth up to £25bn.
Expected to operate for between eight and 15 years, the arrangements will provide the water company with its principal commercial and delivery structure across the AMP9, AMP10, and AMP11 regulatory periods. Formal procurement is scheduled to begin in early 2027, following a programme of pre-market engagement with prospective partners.
Covering water and wastewater infrastructure throughout the Midlands, the frameworks will support projects intended to increase network resilience, accommodate population growth, improve environmental performance, and meet future regulatory commitments. The £25bn figure forms part of Severn Trent’s previously announced long-term investment programme, rather than representing an additional commitment outside that pipeline.
A separate competition for design services will run alongside the delivery procurement, with the two processes intended to create a more continuous route from project definition and engineering through construction, commissioning, and operation. Closer integration between designers and delivery partners could reduce the cost and disruption created when buildability, access, or equipment constraints emerge only after a design has reached an advanced stage.
Prospective suppliers will be invited to an engagement event at which Severn Trent will outline its expected pipeline, commercial structure, and requirements for future partners. Further UK procurement notices are due to provide details of the framework lots, eligibility criteria, allocation procedures, and tender timetable.
Paul Baxter, Capital Delivery Director at Severn Trent, said the company wanted to establish a flexible and resilient delivery platform capable of supporting long-term investment. The proposed supply chain is expected to include major international contractors, regional companies, specialist businesses, and SMEs.
As the water sector moves towards larger and more persistent programmes of work, continuity between regulatory periods has become increasingly valuable. Utilities are simultaneously addressing leakage, storm-overflow performance, treatment capacity, environmental compliance, climate resilience, and the renewal of ageing networks, while many projects extend beyond the five-year boundaries used for regulatory settlements.
Short procurement cycles can make it difficult for contractors to retain specialist teams or justify investment in plant, technology, training, and regional facilities. A framework lasting up to 15 years offers a stronger foundation for workforce planning and capital expenditure, although the certainty available to individual suppliers will depend on the eventual allocation mechanisms and minimum workload commitments.
Commercial terms will carry particular weight because large headline values do not guarantee an even or predictable distribution of projects. Suppliers will be looking for clarity on inflation, indexation, payment, liability, bonding, insurance, design responsibility, and the treatment of programmes that change between regulatory settlements.
By involving contractors and specialists earlier, Severn Trent could identify buildability problems, access restrictions, long-lead equipment requirements, planning constraints, and environmental risks before they become embedded in project budgets. Repeated assets such as pumping stations, treatment units, chambers, and network structures may also provide opportunities for greater standardisation and off-site manufacture.
The scale of the planned programme will place additional demands on a market already serving other water companies, energy networks, transport schemes, and public infrastructure clients. Civil engineers, mechanical and electrical specialists, commissioning personnel, planners, commercial managers, and environmental professionals are likely to remain in strong demand as AMP8 activity expands and preparations for AMP9 accelerate.
Regional and local participation will depend on work packages being proportionate to the financial and operational capacity of smaller companies. Lengthy payment periods, extensive bonding, broad liability clauses, or poorly defined pipelines can exclude SMEs even when a framework formally encourages their involvement.
Continuity from the current investment period is also being built into the procurement strategy, with AMP8 projects expected to remain with existing partners while the new frameworks are introduced. Managing that transition should reduce the risk of disrupting active programmes, dispersing established teams, or losing technical knowledge at the regulatory boundary.
During the pre-market phase, Severn Trent will be able to test whether the proposed commercial structure can attract enough capacity and specialist capability to support three successive regulatory periods. Suppliers, meanwhile, will gain an early view of the resources, partnerships, and financial commitments likely to be required when the main competition opens in 2027.
