Following a spate of rip-offs by cowboy builders, elderly residents are being warned by the council to be vigilant against rogue door-to-door traders.

The council is advising residents to be cautious when responding to work cards or flyers delivered through doors and instead to hire only reputable firms wherever possible.

Artful dodgers have recently tricked a number of people in the borough, including the vulnerable and elderly, into parting with their hard-earned cash.

Councillor Laila Butt, cabinet member for enforcement and community safety, said: “I would like to ask residents to think very carefully before opening their doors for, or parting with their money for any building work to people they are unsure about,” she said.

Residents unsure about door knockers can contact the Citizens Advice consumer helpline on 03454040506 from Monday to Friday, 9am to 5pm.
