On 29 July 2026 Adam Bainbridge, a teacher living in north London, found a £145,562 charge from Thames Water on his Halifax statement. The debit appeared early on a Thursday morning and immediately pushed his account into overdraft.

Thames Water engineers worked to isolate a broken pipe affecting properties across south London and Surrey.
Thames Water told the Standard that the charge resulted from a human mistake linked to an incorrect water‑meter reading. The utility said the figure had no basis in the household’s actual consumption and was far above the normal monthly amount.
It was the shock of his life.

Mrs Julia Bainbridge, who works in public relations, described the moment as a “shock of his life”. She added that the family was trying to get a three‑year‑old ready for nursery when the debit blocked their regular payments.

Bank and utility response
After contacting Halifax, Mr Bainbridge was told the error would be corrected. Halifax confirmed that the Direct Debit guarantee protects customers when a provider takes an incorrect amount, and the money was promptly returned to the Bainbridge account.
A Thames Water spokesperson said the company had apologised “unreservedly” and confirmed the refund. The spokesperson also said a goodwill gesture had been offered to the family and that the utility was working to resolve any remaining issues.
Future safeguards
Thames Water announced it will introduce additional checks into its billing and meter‑reading procedures. The company said the new steps are designed to stop a repeat of the mistake that affected the Bainbridge household.
Customers who notice unexpected direct debits should contact their bank immediately and inform the service provider. The Direct Debit guarantee ensures that any wrongly taken funds are repaid, and providers are expected to investigate and correct the cause.
