Average water bills in England and Wales will increase by 36% over the next five years, the water regulator Ofwat has said.

The rise is equivalent to an average extra cost of £31 per year.

Water companies had asked for an average rise of 40%.

The regulator’s draft determinations issued in July said bills would rise by an average of 21% up to 2030.

It comes as almost 60,000 homes across Hampshire are without water because of a “technical issue” at a Southern Water supply works.

Southern Water customers will experience the biggest rise in the cost of bills of all eleven water and wastewater companies – a 53% hike. The company had sought an increase of 83%.

Customers of Wessex Water will have the lowest, 21%, bill rise.

The 16 million customers of the UK’s biggest water company Thames Water will see bills become 35% more expensive, below the 53% increase requested by the utility.

By 2030 a typical annual bill will cost £588.

Paying the most every year in five years’ time will be Dwr Cymru customers, with an average annual bill of £645.

Why are bills going up?

Bills are going up as the utilities face a range of problems – including higher borrowing costs on large levels of debt, creaking infrastructure and record sewage outflows into waterways.

Ofwat has now agreed to investment plans by the water companies. Funding this investment is another reason bills have been allowed to rise.

The regulator has approved £104bn in funding, above the £85bn agreed with firms in Ofwat’s draft determination but just below the £108bn the companies wanted.

Higher bills will not solve the financial woes at some of the utilities, including Thames Water, which this week won court approval to pursue the next phase in securing a £3bn emergency loan.

If approval had not been granted Thames Water told the High Court it would run out of cash by 24 March and would likely be pushed into a government-backed special administration regime.

Ofwat chief executive David Black said: “We recognise it is a difficult time for many, and we are acutely aware of the impact that bill increases will have for some customers. That is why it is vital that companies are stepping up their support for customers who struggle to pay.

“We have robustly examined all funding requests to make sure they provide value for money and deliver real improvements while ensuring the sector can attract the levels of investment it needs to meet environmental requirements.”

How have companies and the government reacted?

A representative for the water industry body Water UK said: “This will be the largest amount of money ever spent on the natural environment and will help to support economic growth, build more homes, secure our water supplies and end sewage entering our rivers and seas.

“We understand increasing bills is never welcome. To protect vulnerable customers, companies will triple the number of households receiving support with their bills to three million over the next five years.”

The Environment Secretary Steve Reed said: “The public are right to be angry after they have been left to pay the price of Conservative failure.

“This Labour government will ringfence money earmarked for investment so it can never be diverted for bonuses and shareholder payouts. We will clean up our rivers, lakes and seas for good.”

A man accused of murdering a racing commentator’s wife and two daughters has been further charged with rape.

Kyle Clifford, 26, was previously accused of fatally shooting Louise and Hannah Hunt with a crossbow and stabbing Carol Hunt, the wife of John Hunt, to death at their home in Bushey, Hertfordshire, on 9 July.

Clifford pleaded not guilty to the three murders today.

He is also charged with two counts of possession of an offensive weapon – one a 10-inch butcher’s knife and the other a compound crossbow.

Clifford, of Enfield, north London, also faces a charge of false imprisonment.

He was further charged with rape at a plea hearing at Cambridge Crown Court this afternoon.

The defendant, who appeared via video link from HMP Belmarsh, entered not guilty pleas to all charges except the new count of rape, for which he is not yet required to enter a plea.

A memorial service was held in Bushey for Mrs Hunt and her daughters Louise and Hannah a few days after their deaths, with friends saying they were “together in grief”.

Mr Hunt, a Sky Sports and BBC racing commentator, said the devastation he and his surviving daughter Amy feel “cannot be put into words”.

Colleagues of Hannah Hunt paid tribute to the “fantastic therapist”, while a friend of Louise Hunt described her as “one of the loveliest girls” who “always had a smile and was very positive and hardworking”.

The UK’s youngest murderers since James Bulger’s killing have been handed longer sentences after judges agreed their original terms was too lenient.

The two boys, now 13 and who cannot be identified, were given life sentences with minimum terms of eight-and-a-half years for the murder of 19-year-old Shawn Seesahai in Wolverhampton on 13 November last year.

The solicitor general applied to increase those terms claiming they were “unduly lenient”.

Judges at the Court of Appeal have now agreed to change their sentences to 10 years.

The defendants, who were both 12 at the time of the attack, were described during their sentencing in September as the country’s “youngest knife murderers”.

Mr Seesahai was stabbed through the heart and lungs and suffered a skull fracture during the attack on Stowlawn playing fields in East Park.

One of the wounds he suffered measured 23cm deep – almost passing through his body.

They accused each other of wielding the machete but were found to be jointly responsible for the attack, which trial judge Mrs Justice Tipples called “horrific and shocking”.

The boys are believed to be the youngest convicted of murder in the UK since James Bulger’s 11-year-old killers in 1993.
