Rogue traders tend to be unscrupulous workmen who target the elderly and vulnerable. They usually cold call for custom, then dupe the householder. One common trick is to give a quote but raise the price once work has begun.

Police are working with Trading Standards, the Department of Work and Pensions, the Borders and Immigration Agency and HM Revenue and Customs. This means Rogue Traders won’t just be dealt with for any Trading Standards offences or fraud, but if they infringe employment law, hire illegal workers or don’t pay taxes.

The key message police want to get across is: "If in doubt, keep them out".

If you need to do work on your home, get three quotes from reputable local tradesmen – try to get recommendations from friends or family.
