When: May-September
Where: Jubilee Gardens, South Bank
What: This summer-long pop-up cabaret festival offers an embarrassment of riches, including its fair share of comedy delights. Previous acts include Barry & Stuart, Heath Franklin's Chopper and Frisky & Mannish, and for 2013 Al Murray, The Horne Section and Rob Delaney are all programmed in.

When: Late July-late August
Where: Various venues in Camden
What: The Camden Fringe hosts comedy, theatre, music and more, for the entire month of August. It clashes with the Edinburgh Fringe, meaning the quality can be a little hit and miss, comedy-wise. Nevertheless, there are always some enjoyable names playing throughout the month.
When: Mid-February
Where: Various venues in and around Leicester
What: Apart from the Edinburgh Fringe, the Leicester Comedy Festival is arguably the biggest event in the UK comedy calendar.

Where: Various venues in and around Bath

With venues including the RSC and a specially pitched spiegeltent, most of the shows include line-ups of four comics (each with a huge-name headliner), plus the odd late night party. Sounds fun!

Where: Various venues in Inverness
What: A weekend of funny up in the Highlands, featuring a mix of Scottish and British acts on line-up shows, and TV regulars performing solo shows.
When: Late-May/early-June
Where: Various venues in Kilkenny
What: Kilkenny is one of the most respected comedy festivals in the world. For a long weekend this tiny Irish town is riddled with top comedy talent. The Cat Laughs has scored some huge coups in the past – Bill Murray, Zach Galafianakis and Louis CK have all played the festival – and each year usually features some big-name American acts. It's heaps of fun.
