Scottish Water has unveiled a £13.4 billion investment plan aimed at future-proofing its ageing infrastructure, addressing climate challenges, and maintaining its position as one of the most affordable water utilities in the UK. This six-year programme, spanning from 2027 to 2033, will focus on critical areas essential for sustaining high-quality water and wastewater services across Scotland.
A significant portion of the investment, £8 billion, will be directed towards maintaining and upgrading pipes, treatment works, and other core infrastructure. The remaining £5.4 billion will cover operating costs and essential expenses to ensure the safe and efficient delivery of services. This comprehensive approach underscores Scottish Water’s commitment to balancing immediate needs with long-term sustainability.
The investment will be distributed across all regions of Scotland, providing a substantial boost to local economies. By supporting jobs, skills development, and local supply chains, Scottish Water aims to create a ripple effect that benefits communities nationwide. Chief Executive Alex Plant emphasized the collaborative nature of the plan, noting that over 25,000 people contributed to its development. “This plan sets out how we can continue to provide high-quality, reliable water and wastewater services for Scotland, while keeping customer bills as low as possible,” Plant stated. “More than 25,000 people helped shape this plan, and their message was clear – protect essential services, invest for the future, but do so in a way that is fair and affordable.”
Plant also highlighted the utility’s competitive pricing, asserting that Scottish Water’s charges are among the lowest in the UK. As a publicly owned entity, every penny collected from customers is reinvested into service improvements. To fund the ambitious programme, annual customer charges are proposed to increase by 3.3% above the Consumer Price Index (CPI). Despite this rise, over 53% of households already receive some form of financial support, and these assistance schemes will continue.
The proposed plan will now undergo scrutiny by the Water Industry Commission for Scotland. A draft determination is expected in June, followed by a Final Determination in October 2026, which will confirm the investment levels and charges for the 2027–2033 period. A detailed Delivery Plan will subsequently be released, outlining the specific steps and strategies to achieve the outlined objectives.
This investment plan not only addresses immediate infrastructure needs but also positions Scottish Water to tackle the evolving challenges posed by climate change. By prioritizing resilience and sustainability, the utility aims to ensure that Scotland’s water and wastewater services remain robust and reliable for future generations. The collaborative and inclusive approach taken in developing this plan reflects a broader commitment to transparency and customer engagement, setting a benchmark for the water management sector.
