In January 2026, the UK government issued a white paper aimed at addressing some of the appalling deficiencies with the UK’s waterways and water provision, forty years on from the Thatcherite privatisation that wrecked safe and economical water supply.
An example of the problems faced is demonstrated by one private water company, Thames Water, being fined in May 2025, for over £120m for environmental breaches involving sewage spills, after failing to operate and manage its treatment works and wastewater networks effectively.
Sewage pollution
According to the Rivers Trust, the UK Environment Agency has reported that raw sewage was discharged into England’s rivers for an unprecedented total of over 3.6 million hours, marking a record high (for 2024). This resulted in 450,398 monitored spill events, indicating a severe pollution issue affecting waterways across the country. The government aims to reduce these discharges to fewer than 10 per year, but current figures show a troubling trend of increasing spills.
This includes directing sewage to the sea, which presents the risk of pathogenic bacteria. Sewage contamination in coastal waters can introduce a variety of harmful microorganisms, including pathogenic bacteria that can cause gastrointestinal, respiratory and skin infections.
Rising water bills
Average water bills have risen since privatisation (when inflation is accounted for, as per House of Commons Library estimates) and have remained relatively stable since 2010, at around £39 per month per household in England. Water bills in all parts of the UK rose between 4.7% and 8.8% for the billing year 2024/25.
UK government reforms 2026
The water white paper sets out that the government intends to reform the water sector to focus on the long term, with “preventative regulation” that addresses issues before problems occur. It says that the government is aiming to do this by:
- establishing a new integrated water regulator
- introducing reforms to focus on long-term priorities
- attracting third-party investment in the water sector
- delivering better outcomes for water customers and the environment, such as improved company responsibility and reduced pollution
Entitled “A New Vision for Water“, the white paper has received mixed reviews.
According to Emma Reynolds, Secretary of State for Environment, Food & Rural Affairs, the vision can be truncated into: “Clean water from our taps. Healthy rivers we can swim in and enjoy. A water system that supports the new homes, jobs and opportunities our country needs. That’s our goal and that’s what this government is delivering.”
It should be noted that Reynolds has close links to the financial sector, having previously been a lobbyist, and hence is most probably open to the continuation of a privatised water supply.
One positive aspect of the document is the commitment to abolish the much lampooned current water regulator (Ofwat), which has limited powers against the privatised water utility companies, and to establish a new regulator. The paper states this new “Integrated water regulator..[will] provide greater stability, transparency, and an integrated view of both economic and environmental performance.”
Dismay from environmental groups
However, how effective will this regulator be in practice? According to The Guardian, water companies could be let off fines for polluting the environment under the changes. This is to the dismay of environmental campaigners.
Richard Benwell, CEO of Wildlife and Countryside Link says: “It sounds like a desperate play to be off the hook at the last minute, and companies should think about that when they are engaging in unlawful actions and failing in their public environmental interest duties. If a business hasn’t managed itself well enough to deal with the consequences of its shortcomings then it needs to deal with those consequences.”
These sentiments are reinforced by Feargal Sharkey, the water campaigner and former singer of the Undertones, says: “This is just a rearrangement of the deckchairs. After 35 years of privatisations we have two hospitals, a kidney treatment centre, 15 schools, 19 care homes and 29 nurseries in Tunbridge Wells left without water for two weeks. The government is terrified of dealing with privatisation and has sacrificed water quality on the altar of shareholders and private equity.
“No 10 is operating under paralysis of doing anything which might slightly spook the bond markets. Ministers have failed to grasp the underlying issue which is corporate greed. The only people who will be paying for this are customers and billpayers.”
Welcomed by industry
In contrast, the reforms have been welcomed by Utility Week (a publication for the utilities sector). The publication notes that the government reforms will revise the price control process; appoint a chair-designate for its new new ‘super’ regulator; as well as the greater leniency over performance penalties.
Mixed opinions from scientists
Others supporting reforms includes The Microbiology Society, who note the move to publicly accessible, open and continuous monitoring of water. The Society observes how the current monitoring practices allow the water companies to downplay their contamination of our waterways for too long.
The Society do have points of concern, and they call on the UK Government and water companies to invest in tertiary and quaternary treatment methods that can remove microbial and pharmaceutical contaminants, thus slowing the spread of antimicrobial resistance (AMR) in wastewater.
Corbyn calls for renationalisation
However, this falls short of bringing the water companies back under public ownership, a move that would enable a stricter environmental policy to be imposed. This is the view of the new party on the left of Labour – Your Party – where leader Jeremy Corbyn has made the case for why water should be brought back into public ownership immediately – saying £72 billion has been taken out of the industry since privatisation.
What is really needed
The white paper will make the oversight of water companies – the subject of much public anger – better. However, the lowering of fines will do nothing other than add to the profits garnered by these companies and hence the moderate policies of Starmer’s government remain too tepid to push the sector in closer alignment with what the UK population needs – a single water company, run on a not-for-profit basis, with a focus on providing clean water for households and avoiding polluting the rivers, streams and seas around the UK.
