Young's pubs are giving out free pints this week as part of a four day long celebration, but there's a catch.

To celebrate Young’s 186th birthday, the company is handing out free pints of beer from Thursday, September 21 to Sunday September 24, but only when you download the app, Young’s on Tap.

A spokesperson for Young's said: "The app will introduce you to a whole host of perks including enjoying the ease of booking a table and paying or splitting the bill using just your phone."
