Activity in London will include TV ads, bus sides, posters, London Underground ads and online work warning 'Get One or Get Done'.
A film noir-style TV ad will inform viewers that TV Licensing has a database of more than 28 million UK homes and is aware of which properties aren't licensed.
The high-profile campaign which will also run in Leeds, Liverpool, Bristol and Bath, will be supported by increased activity by enquiry officers who claim to be visiting more unlicensed addresses.
A consortium of agencies is behind the campaign, including Abbott Mead Vickers BBDO and Proximity London, which is creating DM.
