English water companies have collectively been given the lowest environmental rating by the Environment Agency (EA) since records began.

Companies were ranked on a scale of one to four stars. Out of a maximum score of 36 stars for all nine companies, the firms together scored 19, the lowest since the EA began monitoring.

The only utility to receive the highest four-star rank was Severn Trent, the agency said in its annual performance assessment.

The number of serious incidents, in which “significant” environmental harm was caused, increased by 60% last year compared to 2023.

Just three companies were responsible for the vast majority of incidents.

Thames Water – the country’s biggest supplier – Southern Water and Yorkshire Water were responsible for 81% of all incidents.

Only two firms out of nine – Northumbrian Water and Wessex Water – recorded no serious incidents.

More monitoring, inspections and data have meant that knowledge of pollution in English waterways is now greater than ever. In turn, the amount of reporting has been greater.

Other factors driving the figures are underinvestment and poor maintenance of infrastructure, as well as wet and stormy weather.

Firms have again been called on by the Environment Agency to “urgently” improve their performance. There had previously been a trend of improvement since records began in 2011, but the latest figures indicated a “dip”.

In addition to pollution incidents, companies were assessed on self-reporting and compliance with permits.

A separate report by water regulator Ofwat published on Thursday showed “mixed” performance with improvements in sewer flooding and pipe leakage, but only two companies reported a reduction in pollution incidents over five years.

Regulation of the sector has been criticised in a once-in-a-generation review of the water industry by career civil servant Sir Jon Cunliffe. In the wake of it, the government says Ofwat is to be retired.

Pressure has mounted on utilities across the UK as the public has sought action on poor water quality and rising bills.

Thames Water, in particular, is struggling under a £20bn debt pile with the government lining up insolvency practitioners.

An autistic man who was told he could no longer stack shelves at Waitrose when he asked to be paid has been offered a job by Asda.

Tom Boyd, 28, began volunteering unpaid at the branch of Waitrose in Cheadle Hulme, Greater Manchester, in 2021, supported by a care worker, to develop skills for the workplace on a further education course he was taking.

The work gave him a sense of “purpose and belonging”, his mother, Frances Boyd, told the BBC.

When she asked in July if he could be paid for a few hours every week, however, the supermarket’s head office told him he had to stop and could not return to the shop.

Ms Boyd said they felt “deeply let down” by the decision as he had taken great pride in his work, which included putting out stock and tidying the shelves.

“If I went in and saw him, he was smiling, and it gave him independence, a sense of purpose and belonging,” she said.

“He gave over 600 hours of his time purely because he wanted to belong, contribute, and make a difference…

“He deserved better. He deserved kindness, respect and the chance for all his hard work to mean something.”

Mr Boyd has now been offered two paid five-hour shifts each week by Asda.

“It’s overwhelming and they are flexible to say if at any time he is struggling they are fine,” his mother said.

“How amazing that a company could do this.”

Welcoming the news on X, Greater Manchester mayor Andy Burnham said he hoped it would lead to more employers accepting a neurodivergent code of best practice he has launched.

An Asda spokesperson said that when the store heard about Mr Boyd’s desire to find meaningful work they knew he would be a “fantastic fit” and were delighted to offer him a role.

“We know that finding meaningful work can be especially challenging for individuals with learning disabilities or difficulties,” they said.

“Asda has a Supported Internship Programme and partnership with DFN Project SEARCH, through which we have welcomed over 30 talented new colleagues into roles across our stores. We have seen the positive impact this has for the individuals who join and for our colleagues and customers too.”

A Waitrose spokesperson said they “care deeply” about helping people into the workplace who might not otherwise be given a chance and that the chain is currently investigating what happened to Mr Boyd.

“We’d like to welcome Tom back, in paid employment, and are seeking support from his family and the charity to do so. We hope to see him back with us very soon,” they added.
