More than 200 people have been caught watching TV without a licence in Chorley in the last six months.
Figures released by TV Licensing indicate that Chorley residents have been fined up to £200,000 for watching TV illegally, with culprits facing punishment fees of up to £1,000.
The statistics compare to more than 700 people in Preston and 130 in Leyland.
Tim Downs, from TV Licensing in the North, said: “We have to be firm with those who try to get away without paying.
“We take TV licence evasion very seriously and we will not hesitate to prosecute if people continue to break the law.”
A colour licence currently costs £145.50 and is required by anyone watching or recording programmes, whether they are using a TV set, computer, or any other equipment.
Anyone watching TV illegally also risks prosecution.
