Water companies in England and Wales are embarking on the biggest investment programme in their history, with £104bn allocated for upgrades to pipes and treatment works between 2025 and 2030. However, experts warn that contractor shortages and inflation may hinder spending.
The need for investment is clear: ageing infrastructure has led to sewage spills, leaks, and recent water outages affecting thousands. Six companies were banned from paying executive bonuses in the year to June due to serious pollution issues. Yet campaign group River Action argues households are paying twice, as previous bills should have funded these repairs.
Labour plans to overhaul regulation by replacing Ofwat with a new system that regulates each company individually. While that change takes time, the current regulator has approved a 36% average bill increase to fund the programme. Water UK says the hike is needed to catch up on decades of underinvestment.
Water firms will compete for builders with other major government projects, including 1.5m new homes, £28bn in energy grid upgrades, and new nuclear reactors. This competition could further drive up costs and delay improvements, raising questions about whether the spending spree will deliver on time and on budget.
