TRADING standards officers in West Yorkshire have launched a policy to name and shame dodgy traders.
And the first business to be publicly exposed under the policy is a uPVC fascias and guttering firm, Quality Plastics, thought to be working in Bradford.
A trading standards spokesman said: "Quality Plastics are itinerant traders, who rely on cold calling to generate trade at the doorstep.
"Their work is poor and sometimes not needed in the first place.
"Complaints have come from various parts of West Yorkshire, with older consumers being targeted and persuaded to part with considerable amounts of money."
Trading standards officers have contacted the firm and found staff aggressive and unco-operative.
Bills and guarantees given to customers are false and do not contain an address. The firm trades from the phone number 01274 734019, connecting to a caravan site in the Bradford district. A mobile number, 07814 677628, has also been given to customers.
Trading standards officials want to prevent consumers falling victim to dodgy doorstep tactics.
The message for consumers is to avoid doorstep callers all together.
If you have a complaint phone the consumer helpline on 0113 384 8848.
A newly formed rapid response team is available to help consumers, particularly those from vulnerable groups, who fall prey to itinerant traders.
Clr Graham Clarke, chairman of West Yorkshire Trading Standards, said "This kind of company preys on vulnerable consumers.
"We will do everything in our power to stop them ripping off the consumers of West Yorkshire, which is why we are naming them to the public.
"I urge everybody to remember the dangers of dealing on the doorstep and to say no to dodgy doorstep traders."
