* The television licence fee: This is a compulsory annual charge levied on all UK households that own a television set. The licence fee is set by the government and is currently £159 per year.
* Commercial revenue: This includes advertising revenue from BBC Radio 1 and BBC Radio 2, as well as sponsorship and product placement.
* Government grant-in-aid: This is a grant from the government that helps to cover the costs of public service broadcasting, such as news and current affairs programmes.
* Other revenue: This includes income from the BBC's overseas operations, such as BBC World Service, as well as income from merchandising and licensing.
The BBC is a non-profit organisation and all of its revenue is reinvested back into the organisation. This ensures that the BBC can continue to provide high-quality public service broadcasting.
