The sector was heavily targeted by fraudsters between January and March 2026. Cyber and fraud protect officer Ryan Brennan explains how to protect yourself and your business.
UK construction businesses lost more than £200,000 in the first three months of the year due to scammers asking for payments to be diverted, Report Fraud, a division of the police, has shared.
Known as payment diversion fraud, this scam generally involves criminals contacting an organisation’s finance department pretending to be a regular supplier and asking to redirect future direct debits or invoice payments.
Some of the tactics utilised by criminals involve:
- Impersonation: criminals will make contact over email or phone call while impersonating existing suppliers, or sometimes staff within your own organisation
- Urgency and secrecy: they pressure you to act quickly and ask you not to share the request with others
- Changed payment details: they will claim that the supplier has changed their bank and future payments need to be paid into the new account
How to protect yourself
- Verify: if you receive a request to move money into a new bank account, contact the supplier directly using established contact details to verify and corroborate the payment request.
- Internal processes: establish robust internal processes for handling changes to payment details. For example, only designated employees should be able to make changes to payment arrangements.
- Payment method: avoid paying by bank transfer as it offers you little protection if you become a victim of fraud. Instead, use a credit card or payment services such as PayPal.
- Sensitive information: invoices, payment mandates, and other documents containing sensitive financial information should be stored securely and only be accessible to staff that need them to perform their duties. Sensitive documents should be shredded before they are disposed of.
