Negative online reviews are usually no reason to panic, but for one consumer it has proved costly.

A disgruntled man who left a negative review of a legal firm on the TrustPilot website, referring to their service as a “a total waste of money” has been ordered to pay £25,000 in libel damages.

Philip James Waymouth claimed that London law firm Summerfield Browne had provided him with a service “full of errors” that showed a lack of understanding of the law.

He then left a scathing review accusing the company of being “another scam solicitor” after engaging with them online.

He had hired the company in a dispute over the enforcement of a court order for a fixed fee of £200, court documents show.

Waymouth wrote in his review: “Once they have your money they are totally apathetic towards you. You will learn more from forums, YouTube and the Citizens Advice website about your case, for free.”

Many businesses, including estate agents, have received negative online reviews in the past, but very few have considered taking legal action against those leaving discouraging feedback.

But acknowledging the importance of reputation management and customer feedback, which can sometimes help people decide if they want to engage with a brand, Summerfield Browne refused to accept the negative feedback received from their client and decided to take legal action, stating that the claims were false and defamatory. This has paved the way for other firms, including estate agencies, to potentially adopt the same approach.

The company claimed that demand for its service had dropped since the publication of the review.

It also turned out that Waymouth had not engaged with Summerfield Browne’s complaints procedure before leaving the negative review, the High Court in London heard.

Waymouth offered to remove the review in exchange for a refund of the £200 fee plus VAT he had paid but claimed Summerfield Browne had not responded.

In the review, Waymouth alleged: “I paid upfront for a legal assessment of my case.

“But what I got was just the information I sent them, reworded and sent back to me.”

Waymouth was not legally represented and refused to attend the remote hearing, claiming he was living overseas.

In his ruling backing Summerfield Browne, judge Master David Cook said: “It is beyond any dispute that the words complained of had a clear tendency to put people off dealing with the claimant firm.

“It is a serious matter to accuse a solicitors’ firm of dishonesty and any such allegation is likely to deter those who are unfamiliar with the firm from using its services. There is supportive evidence that the number of inquiries fell dramatically after the review was posted.”
