Do you play music of any kind in your premises?
This includes CD's, MP3's or Radio Stations.
If you do, you may need a Music Licence from the Performing Rights Society who pay 90p in every pound back to the music creators, composers and publishers of the music.. A music licence could cost as little as £44 (excluding VAT) for a small office.

Note: You may also need to check your requirement for a TV licence. Even watching broadcasts over the Internet e.g. BBC iplayer means you will need to have a licence.
