From AMP7 To PR29: Why Static Design Approaches No Longer Work

The transition from AMP7 to PR29 marks a pivotal moment for the UK water sector. While AMP7 delivered important infrastructure upgrades, it also exposed significant shortcomings—from pollution incidents to delivery delays and declining public trust. With AMP8 doubling investment to £104 billion, simply increasing capital is not enough. The methods used to plan, design, and justify that investment must also evolve.

Traditional “static” design approaches—limited optioneering, high-level cost estimates, and linear planning processes—are no longer fit for purpose. These methods often produce weak analytical foundations, making investment cases vulnerable to regulatory challenge and increasing the risk of project inefficiencies and underperformance.

Dynamic design offers a fundamentally different approach. By treating early-stage design as a rigorous analytical process, it enables engineers to evaluate multiple design options quickly and at engineering-level detail. Automated, rules-based platforms can generate comprehensive alternatives with detailed cost, performance, and outcome data, allowing for more robust decision-making and stronger investment justification.

This shift directly addresses many of AMP7’s challenges. Better optioneering improves infrastructure resilience, engineering-grade specifications reduce delivery risk, and structured, auditable data strengthens regulatory credibility.

AMP8 provides a critical window to adopt these capabilities. Companies that invest now in dynamic, digital-first design approaches will build the analytical strength needed for PR29—delivering more credible investment cases, improved operational outcomes, and a stronger position in an increasingly demanding regulatory environment.
