Severn Trent Water Bills to Double National Average Increase

Severn Trent Water customers will soon experience a notable hike in their water bills starting April 1, 2026. This increase is approximately 10 percent, resulting in an average annual charge of £587, which represents an additional £52 compared to the previous year. This rise significantly exceeds the national average increase of around 5.4 percent across water services in England and Wales.

Overview of the Bill Increase

Severn Trent Water’s increase in charges indicates that customers will face nearly double the national average rise. This increase is part of a broader strategy within the water industry to enhance services, as companies plan to invest extensively in infrastructure.

Investment Plans

For the fiscal year 2026-27, an estimated £20 billion will be allocated to improve water supplies, modernize infrastructure, and reduce sewage spills into rivers. This substantial financial commitment is essential to address ongoing environmental challenges and enhance customer service.

Long-Term Projections

The recent announcements are part of a more extensive trend in water pricing, with regulatory bodies approving plans that could elevate average bills by up to 47 percent by 2030. Consequently, customers should prepare for additional increases in the coming years.

Impacts on Households

These changes will impact millions of households served by Severn Trent Water, particularly in the Midlands and parts of Wales. As the cost of living rises—with escalating energy prices, council taxes, and other essentials—the new water bills add to consumer financial strain.

Comparative Analysis of Bill Sizes

• Average annual bill for Severn Trent in 2026-27: £587
• National average for water and waste services: £660
• Highest water bill in England and Wales: £759
• Severn Trent’s bill is £73 below the national average and £172 lower than the highest.

In percentage terms, the 10 percent increase from Severn Trent ranks as the fourth highest among water companies in the UK. By comparison, Affinity Water’s charges are increasing by 13 percent, Bristol Water by 12 percent, and SES Water by 11 percent. In terms of cash, Severn Trent’s £52 increase is more reasonable than the rises observed in other companies.

Customer Support Initiatives

Severn Trent recognizes the challenges that such increases can pose and aims to assist their customers. The company plans to extend financial support to one in six households by 2030. Eligible customers may receive discounts of up to £390 on their bills, along with debt support options.

Investments for Improvement

In addition to increased support, Severn Trent is committed to investing approximately £15 billion in the Midlands by 2030. The investment will facilitate:

• £415 million for laying over 870 miles of new water pipes.
• Over £1.7 billion focused on improving river health and managing sewage spills.
• Creation of approximately 7,000 jobs within the region.

While the increase in water bills is challenging, Severn Trent Water’s continuous efforts to enhance services demonstrate their commitment to customer care and environmental responsibility.
