More than 2,270 people were caught without a TV licence in Doncaster last year.
This is compared to 1,510 in Barnsley, 1,890 in Rotherham and more than 3,970 in Sheffield and 9,760 people across South Yorkshire.
It is estimated that the number of people without a TV licence has remained steady at about five per cent - the level it has been for the last five years.
Tim Downs, TV Licensing spokesperson for Northern England, said: “TV viewing is as popular as ever, with the percentage of households who have a television set at 96.7 per cent, and it’s our role to make sure everyone is aware of when they need to be covered by a licence.
“On behalf of licence fee payers in Doncaster, we are committed to tackling evasion and enforcing the law amongst the small minority who should pay, but don’t. It’s only fair.
“People are given every opportunity to pay, but, if they fail to do so and watch TV illegally, we will seek a prosecution. The penalty is a fine of up to £1,000, plus court costs and a victim surcharge.
“Anyone found guilty is also required to buy a TV Licence at £145.50 if they still need one or they could face a second prosecution. It’s really not worth the risk.”
