The decline began to stabilise in the mid-1990s with the resurgence of interest in folk music and there are now over 160 folk clubs in the United Kingdom, including many that can trace their origins back to the 1950s including The Bridge Folk Club in Newcastle (previously called the Folk Song and Ballad club) claims to the oldest club still in existence in its original venue (1953)

The nature of surviving folk clubs has also changed significantly, many larger clubs use PA systems, opening the door to use of electric instruments, although drums and full electric line-ups remain rare. The mix of music often includes American roots music, blues, British folk rock, and world music as well as traditional British folk music. From 2000 the BBC Radio 2 folk awards have included an award for the best folk club
