Boro'line London was a bus operator that operated bus services under contract to London Regional Transport. It was owned by Maidstone Borough Council who already operated Boro'line Maidstone. It experienced initial rapid success, gaining and operating some of the first services to be contracted out in the Bexleyheath area of South East London. Later services reached Greenwich, Stratford and Euston station. However, the company quickly encountered problems, and on 17 February 1992 sold its London operations to Kentish Bus. Two days later, Boro'line was placed into administration.
