Residents in Rushden have been warned about men who are cleaning people’s windows and requesting payment without being asked to carry out the work.
Police have received calls of suspicious behaviour in Gloucester Crescent and Wilmott Road in the town from concerned homeowners who had returned home to find an invoice through their door.
One Facebook comment read: “Just come home and found that someone has cleaned our front windows then jumped over the fence to clean the back windows, leaving our gate unlocked and garden insecure with an invoice for £12.”
A spokesman for Northamptonshire County Council’s trading standards team said: “If you have been affected by this issue or have concerns about any other businesses operating in your area please contact our trading standards service by calling Citizens Advice Consumer Service on 03454 04 05 06.
“The advice of trading standards and the police is not to buy goods or services from a cold caller on your doorstep.
“Residents looking to have work carried out around their home or garden can find a trading standards approved business through the Buy With Confidence scheme by visiting www.northamptonshire.gov.uk/approvedtraders or by calling 0300 126 1000.”
Police say their investigations into the reports are ongoing, to see if any criminal offences have been committed.
Trading standards officers will also be investigating the complaints.
