Slip End is a village and civil parish in Central Bedfordshire, England. The village is located very near to Luton. As well as the village of Slip End, the parish contains the hamlets of Lower Woodside, Woodside and Pepperstock. In 2001 it had a population of 1,976, reducing to 1,831 at the 2011 Census. Another plausible explanation is that 'the slip' in fact is a very deep deposit of clay, situated between the stratas of chalk which form the bedrock of Central Bedfordshire. The southerly extremity of the slip terminates at the appropriately named Slip End.
