Homeowners are being cautioned about an emerging scam involving fraudulent surveyors who use publicly available planning application data to target individuals undertaking home renovations. These scammers send aggressive, official-looking letters to neighbouring property owners, pressuring them to appoint their services for party wall agreements, often urging immediate action by creating a false sense of legal urgency.

Paula Higgins, chief executive of HomeOwners Alliance, explained that scammers easily access planning applications to identify adjacent properties. They then dispatch sales letters that imply homeowners are already engaged in a formal legal process, which is not always the case. Such letters often suggest urgent requirements to retain a party wall surveyor, encouraging homeowners to make quick decisions under pressure.

Oliver Burgess of Resi, a home design service, noted that the ease of establishing such firms has led to a sharp increase in these operations. “A company with no track record can incorporate and start sending letters within days,” he said. Burgess attributes this rise to the relatively low barriers to entry and the ability to produce documents that sound legal and authoritative. He also highlighted that many affected clients report feeling blindsided, as the purported urgency is not typically flagged by their architects or discussed beforehand.

One case cited involved Sarah Hartley, 28, and her fiancé, Tom Dunn, 31, from Bedfordshire, whose extension plans were delayed for months due to one such fraudulent surveyor. Hartley described the experience as “harassment,” with her neighbours receiving intimidating letters warning of potential liability for costly repairs due to construction issues. After her neighbour agreed to representation, the couple received persistent emails demanding responses and implying possible legal violations if ignored. The company requested around £2,000 for 8 to 12 hours of work. The correspondence continued for three months, generating significant stress before the neighbours withdrew their consent for the surveyor’s involvement.

A party wall agreement is legally required when homeowners plan alterations to walls shared between adjacent properties or when building near a neighbour’s foundation. Before construction, homeowners must serve a formal notice to neighbours. If the neighbour consents in writing within 14 days, no party wall agreement or surveyor fees are necessary, although a signed notice remains important for future property transactions. More complex projects may require professional party wall surveyors.

Burgess advised homeowners to verify the credentials of any surveyor issuing a notice by checking their company name, online presence, and registration with the Royal Institution of Chartered Surveyors (RICS). To counteract the scam, his company has adjusted its procedures by appointing trusted party wall surveyors early in the planning stage, prior to the public availability of planning applications. This approach aims to provide clients and neighbours a reliable route for handling party wall matters before exposure to fraudulent operators.

Authorities and industry representatives are urging vigilance and awareness to protect homeowners from these increasingly common scams, emphasizing the importance of checking the legitimacy of surveyors and understanding the correct legal processes surrounding party wall agreements.
