Counties 4 Surrey
Counties 4 Surrey is a rugby union competition covering the English county of Surrey and parts of south-west London. It sits at the 10th tier of the English rugby union system. The teams play home and away matches from September through to April. Promoted teams move up to Surrey 3 and relegated teams move down to Counties 5 Surrey. At the end of the 1999–2000 season, Surrey 4 was cancelled with teams automatically going up to Surrey 3 or dropping out of the league. After a hiatus of four seasons the division was reinstated.
Each year some of the clubs in this division also take part in the RFU Junior Vase – a level 9–11 national competition.
