Depending on the nature of the business, playing music within a work environment is fairly common nowadays. Whether it's an employee's favourite album, a playlist from head office or everyone's #1 radio station - whether your like or not - a licence is legally required. It's known as TheMusicLicence.
Who needs a licence?
For the most part, every business will need to make an application and pay the fee - regardless of your sector. You will even need to apply for a licence if you run a church of public transport company.
How much is it going to cost?
The cost of the licence will be totally dependent on the venue and type of business. For example, background music played within a bar, restaurant or café ranges from £140 - £357 annually depending on the building's square footage.
