Thames Water prosecuted for multiple street works offences

Thames Water was successfully prosecuted by Kensington and Chelsea Council on Tuesday 13 May 2025 for carrying out unsafe works in Marloes Road in Kensington.

Over £100,000 fines issued

District Judge Snow ordered Thames Water to pay fines of £96,000, a £2,000 victim surcharge and Council costs of £20,623. The judge also issued fines for works in Pembroke Walk, King’s Road, Walton Street and Ladbroke Grove. The company was handed fines totalling £118,623 during the hearing.

Several safety hazards at work sites

The case was brought forward by Kensington and Chelsea Council’s network management team following inspections at the work sites where officers found several safety hazards at work sites. Thames Water operatives failed to provide a safe alternative route, blocked footways and failed to co-operate with the Council while carrying out work across the borough.

Prioritising safety and protecting our amazing spaces

Cllr Johnny Thalassites, Lead Member for environment and planning said:

 

“We work hard in this borough to protect our amazing spaces and keep our streets safe. This prosecution sends a clear message to all companies that prioritising safety is non-negotiable in Kensington and Chelsea. 

“Council officers are diligent and proactive, visiting work sites regularly to make sure works are carried out safely are properly authorised. Despite previous warnings, Thames Water failed to take advice and disregarded the law.”
