Channel 4's 'Dirty Business' Draws Comparisons to Post Office Scandal Drama

Channel 4 viewers have lavished praise on a new drama, describing it as the 'new Mr Bates Vs The Post Office', with many gripped by its 'harrowing and tragic' scenes. Dirty Business, which premiered on Monday night, is based on the true story of former detective Ash Smith and his neighbour, university professor Peter Hammond.

Uncovering a Decade-Long Sewage Scandal

The series follows the duo as they investigate water companies across England after encountering sewage-polluted water in their town, noticing fish dying and water turning brown in the local river. What begins as a casual complaint in the pub soon escalates into a ten-year deep dive, uncovering illegal pollution and widespread corporate failure by private water firms. The drama exposes how raw sewage is being pumped into Britain's rivers and coastal waters on a massive scale, sparking a national campaign.

The synopsis reads: 'Dirty Business follows the story of two unlikely detectives, who notice fish in the river running through their idyllic Oxfordshire hamlet are dying. They contact their water company to find out why, and the company’s strange and evasive reply sparks an investigation that remains ongoing to this day.'

Heartbreaking Real-Life Story Featured

The first episode of the three-part series dramatises the real-life tragedy of the Preen family, whose eight-year-old daughter Heather died after contracting E. coli 0157 from playing on a beach contaminated by raw sewage. Starring David Thewlis as Ash and Jason Watkins as Peter, the show depicts water companies shrugging off Heather's death as unrelated to sewage contamination, leaving viewers in shock.

Fans quickly took to social media to draw parallels with the ITV drama Mr Bates vs the Post Office, which highlighted the Post Office Horizon scandal and led to public outrage, faster compensation, and overturned convictions. One viewer wrote: 'Of all the things to privatise, #DirtyBusiness is perfectly exposing why Water should never, ever have been! Shocking.' Another added: 'Post Office2.0 this,' while a third noted: 'The death of Heather Preen alone should have been enough for real change to begin. But 27 years later it's got much much worse. The system has failed on this. #DirtyBusiness.'

Public Outrage and Environmental Crisis

Viewers encouraged others to watch the series, with one stating: 'If you missed the first episode of #DirtyBusiness on Ch4 tonight, I encourage you to catch up. And when you do, have a look at the levels of sewage pouring into your nearest river RIGHT NOW.' Others expressed hope that the drama would induce similar public outrage as the Post Office scandal, with comments like: 'I hope #DirtyBusiness will induce the same public outrage as the post office scandal did.' A sixth viewer concluded: '#DirtyBusiness on C4 is up there with Mr Bates v The Post Office. Congratulations #C4 on a wonderful required viewing #DirtyBusiness . Harrowing and tragic.'

The drama also features an exclusive interview with Heather's mother, Julie Maughan, who described the moment 'a bomb exploded on her family' when her daughter passed away. Heather contracted E. coli O157 while playing on a Blue Flag beach in Dawlish, despite the family noticing 'yucky' water with toilet paper flowing from a pipe. Julie recalled how environmental health officials refused to close the beach, with South West Water quickly ruling out sewage as the cause, instead suggesting dog poo as a source—a claim she disputed.

Ongoing Pollution and Legal Battles

Although no direct link was proven at Heather's inquest, it was revealed that there had been 14 complaints about sewage on that beach, with five other E. coli cases reported. Last year, Environment Agency statistics showed over 450,000 sewage spills in 2024, totalling 3.6 million hours, with one treatment works in Salcombe Regis leaking filth daily. South West Water attributed the spills to 'illegal connections' and has added treatment capacity, but pollution remains a critical issue.

In a related development, almost 4,000 residents and businesses have begun legal action over pollution in the Wye, Lugg, and Usk rivers, seeking damages and a clean-up. Despite record sewage spills, water firms have paid out more than £112 million in bonuses over the past decade, highlighting ongoing corporate failures. Dirty Business continues to air on Channel 4, streaming in full online, as it sheds light on this environmental and public health crisis.
