If a TV or radio programme that has been broadcast has offended or upset you in some way, you can complain to regulatory body Ofcom, who will investigate the issue. Here's how to complain online.
In the first instance, check Ofcom is the correct body to handle the complaint. For example, issues with bias or accuracy on the BBC are handled by the BBC Trust while complaints about adverts are dealt with by the Advertising Standards Authority (ASA).
Next visit the complaints section of Ofcom's website and providing the programme has already been broadcast you can make a complaint online. You'll need to start by entering your house number and postcode. Next you'll be asked to confirm your address.
Now you'll be asked to input your name and contact details. Then you'll be required to select which broadcast you want to complain about using an electronic programme guide that lets you select a channel, date and the broadcast the complaint is about.
Finally, you'll be asked to detail your complaint in 500 words or less. When complete press Submit and your complaint will be filled with Ofcom, who will asses it against the broadcasting code and decide whether to approach the broadcaster or not.
