Public failed by water regulators and government as bills rise, spending watchdog says
Water regulators and the government have failed to provide a trusted and resilient industry at the same time as bills rise, the state spending watchdog has said.
Public trust in the water sector has reached a record low, according to a report from the National Audit Office (NAO) on the privatised industry.
Not since monitoring began in 2011 has consumer trust been at such a level, it said.
At the same time, households face double-digit bill hikes over the next five years.
The last time bills rose at this rate was just before the global financial crash, between 2004-05 and 2005-06.
Regulation failure
All three water regulators – Ofwat, the Environment Agency and Drinking Water Inspectorate – and the government department for environment, food and rural affairs (Defra) have played a role in the failure, the NAO said, adding they do not know enough about the condition or age of water infrastructure and the level of funding needed to maintain it.
Since the utilities were privatised in 1989, the average rate of replacement for water assets is 125 years, the watchdog said. If the current pace is maintained, it will take 700 years to replace the existing water mains.

Water firms have grappled with leaky pipes and record sewage outflows into UK waterways in recent years, with enforcement action under way against all wastewater companies.
Despite there being three regulators tasked with water, there is no one responsible for proactively inspecting wastewater to prevent environmental harm, the report found.
Instead, regulation is reactive, fining firms when harm has already occurred.
Financial penalties and rewards, however, have not worked as water company performance hasn’t been “consistent or significantly improved” in recent years, the report said.
‘Gaps, inconsistencies, tension’
The NAO called for this to change and for a body to be tasked with the whole process and assets. At present, the Drinking Water Inspectorate monitors water coming into a house, but there is no entity looking at water leaving a property.
Similarly no body is tasked with cybersecurity for wastewater businesses.
As well as there being gaps, “inconsistent” watchdog responsibilities cause “tension” and overlap, the report found.
The Environment Agency has no obligation to balance customer affordability with its duty to the environment when it assesses plans, the NAO said.

Company and investment criticism
Regulators have also been blamed for failing to drive enough funding into the water sector.
From having spoken to investors through numerous meetings, the NAO learnt that confidence had declined, which has made it more expensive to invest in companies providing water.
Even investors found Ofwat’s five-yearly price review process “complex and difficult”, the report said.
Financial resilience of the industry has “weakened” with Ofwat having signalled concerns about the financial resilience of 10 of the 16 major water companies.
Most notably, the UK’s largest provider, Thames Water, faced an uncertain future and potential nationalisation before securing an emergency £3bn loan, adding to its already massive £16bn debt pile.

Water businesses have been overspending, with only some extra spending linked to high inflation in recent years, leading to rising bills, the NAO said.
Over the next 25 years, companies plan to spend £290bn on infrastructure and investment, while Ofwat estimates a further £52bn will be needed to deliver up to 30 water supply projects, including nine reservoirs.
The NAO said regulators do not have a good understanding of the condition of infrastructure assets
What else is going on?
From today, a new government law comes into effect which could see water bosses who cover up illegal sewage spills imprisoned for up to two years.
Such measures are necessary, Defra said, as some water companies have obstructed investigations and failed to hand over evidence on illegal sewage discharges, preventing crackdowns.
Meanwhile, the Independent Water Commission (IWC), led by former Bank of England deputy governor Sir Jon Cunliffe, is carrying out the largest review of the industry since privatisation.
What the regulators and government say?
In response to the report, Ofwat said: “The NAO’s report is an important contribution to the debate about the future of the water industry.
“We agree with the NAO’s recommendations for Ofwat and we continue to progress our work in these areas, and to contribute to the IWC’s wider review of the regulatory framework. We also look forward to the IWC’s recommendations and to working with government and other regulators to better deliver for customers and the environment.”
An Environment Agency spokesperson said: “We have worked closely with the National Audit Office in producing this report and welcome its substantial contribution to the debate on the future of water regulation.
“We recognise the significant challenges facing the water industry. That is why we will be working with Defra and other water regulators to implement the report’s recommendations and update our frameworks to reflect its findings.”
A Defra spokesperson said: “The government has taken urgent action to fix the water industry – but change will not happen overnight.
“We have put water companies under tough special measures through our landmark Water Act, with new powers to ban the payment of bonuses to polluting water bosses and bring tougher criminal charges against them if they break the law.”
Water UK, which represents the water firms, has been contacted for comment.
The UK economy showed strong growth in the first three months of the year, according to official figures.
Gross domestic product (GDP) – the standard measure of an economy’s value – grew 0.7% in the first quarter of 2025, the Office for National Statistics said.
The rise is better than expected. An increase of just 0.6% was anticipated by economists polled by the Reuters news agency.

It’s significantly better than the three months previous, in which a slight economic expansion of just 0.1% was reported for the final quarter of 2024.

The ONS also said there was a small amount of growth last month, as GDP expanded 0.2% in March, which similarly beat expectations.
No growth at all had been forecast for the month.
How did the economy grow?
A large contribution to high GDP growth was an increase in output in the production sector, which rose 1.1%, driven by manufacturing and a 4% increase in water supply, the ONS said.
Also working to push up the GDP figure was 0.7% growth in the biggest part of the UK economy – the services industry.

‘Here’s the concern with GDP figures’
Wholesale, retail and computer programming services all performed well in the quarter, as did car leasing and advertising, the ONS said.
It shows the economy was resilient, as the country headed into the global trade war sparked by President Trump’s so-called ‘liberation day’ tariff announcement on 2 April.
Welcome political news, for now
The data is welcome news for a government who have identified growing the economy as its number one priority.
Chancellor Rachel Reeves is taking the figures as a political win, saying the UK economy has grown faster than the US, Canada, France, Italy and Germany.
“Today’s growth figures show the strength and potential of the UK economy, ” she said.
“Up against a backdrop of global uncertainty, we are making the right choices now in the national interest.”

Such GDP numbers may not continue into April as businesses and consumers were hit with a raft of bill rises, and Mr Trump’s tariffs fired the starting gun on a global trade war.
Last month, water, energy and council tax bills rose across the country while employers faced higher wage costs from the rise in their national insurance contributions and the minimum wage.
But above-inflation wage growth and fading consumer caution could continue to boost the economy.
Foreign state investors would be allowed to hold stakes of up to 15% in British national newspapers, ministers are set to announce amid a two-year battle to resolve an impasse over The Daily Telegraph’s ownership.
Sky News has learnt that the Department for Culture, Media and Sport could announce as soon as Thursday that the new limit is to be imposed following a consultation lasting several months.
The decision to set the ownership threshold at 15% follows an intensive lobbying campaign by newspaper industry executives concerned that a permanent outright ban could cut off a vital source of funding to an already-embattled industry.
It would mean that RedBird IMI, the Abu Dhabi state-backed fund which owns an option to take full ownership of the Telegraph titles, would be able to play a role in the newspapers’ future.

RedBird Capital, the US-based fund, has already said it is exploring the possibility of taking full control of the Telegraph, while IMI would have – if the status quo had been maintained – forced to relinquish any involvement in the right-leaning broadsheets.
One industry source said they had been told to expect a statement from Lisa Nandy, the culture secretary, or another DCMS minister, this week, with the amendment potentially being made in the form of a statutory instrument.
Other than RedBird, a number of suitors for the Telegraph have expressed interest but struggled to raise the funding for a deal.
The most notable of these has been Dovid Efune, owner of The New York Sun, who has been trying for months to raise the £550m sought by RedBird IMI to recoup its outlay.
Another potential offer from Todd Boehly, the Chelsea Football Club co-owner, and media tycoon David Montgomery, has yet to materialise.
RedBird IMI paid £600m in 2023 to acquire a call option that was intended to convert into ownership of the Telegraph newspapers and The Spectator magazine.
That objective was thwarted by a change in media ownership laws – which banned any form of foreign state ownership – amid an outcry from parliamentarians.

The Spectator was then sold last year for £100m to Sir Paul Marshall, the hedge fund billionaire, who has installed Lord Gove, the former cabinet minister, as its editor.
The UAE-based IMI, which is controlled by the UAE’s deputy prime minister and ultimate owner of Manchester City Football Club, Sheikh Mansour bin Zayed Al Nahyan, extended a further £600m to the Barclays to pay off a loan owed to Lloyds Banking Group, with the balance secured against other family-controlled assets.
Other bidders for the Telegraph had included Lord Saatchi, the former advertising mogul, who offered £350m, while Lord Rothermere, the Daily Mail proprietor, pulled out of the bidding last summer amid concerns that he would be blocked on competition grounds.
The Telegraph’s ownership had been left in limbo by a decision taken by Lloyds Banking Group, the principal lender to the Barclay family, to force some of the newspapers’ related corporate entities into a form of insolvency proceedings.
The newspaper auction is being run by Raine Group and Robey Warshaw.
The DCMS declined to comment.
