Families are being warned not to fall prey to illegal rubbish collectors over the festive season and risk a hefty fine.

Great Yarmouth Borough Council is alerting homeowners to unlicensed waste carriers who are more likely to target them over Christmas and New Year, as they produce more rubbish and are at home more often.

The council's environmental rangers are urging residents to be alert to doorstep callers, as it is the legal duty of the householder to check anyone taking waste from their home has a proper licence.

Anyone who uses an illegal collector could be prosecuted and fined up to £5,000 if dumped waste can be traced back to them.

The rangers are currently investigating a number of incidents.

In most cases residents have been cold-called by men offering to take rubbish for a few pounds or carry out full garden or house clearances. But rather than disposing of it legally, they are dumping it. The team is appealing for information to help catch those responsible for two fly-tips – one at Sidegate Road, Hopton, and another at the back of Sandown Road, Yarmouth.

Sylvia Pratt, cabinet member for the environment, said: 'Christmas and New Year is, for most people, a time for good deeds and good cheer, but for some it is a prime opportunity to break the law and exploit others.

'The main message is: do not let your guard down over the festive fortnight – check anyone who comes to collect at your door, whether for general waste and/or scrap metal, has an official waste carrier's licence.'

If you witness fly-tipping, or have information about fly-tippers, call the rangers on 01493 846478.
