'''Regional 1 South East''' (formerly known as '''London & South East Premier''' and '''National League 3 London & South East''') is a level five league in the English rugby union system.<ref name="National 3 Renamed">{{cite web|url=http://oxfordshirerfu.pitchero.com/news/renaming-of-rfu-national-3-leagues-18926/|title=Renaming of RFU National 3 Leagues|publisher=Oxfordshire RFU|access-date=16 July 2017 }}</ref> It is one of six leagues at this level. When this division began in 1987 it was known as London Division 1. The format of the league was changed at the beginning of the 2009–10 season following re-organisation by the Rugby Football Union while the name change from National League 3 to Premier was introduced for the 2017–18 season to make it more obvious that it is a regional league.<ref name="National 3 Renamed"/> London & South East Premier was the highest regional rugby union league covering London and south east England. Following the RFU Adult Competition Review the league was decreased from 14 to 12 and the name changed to Regional 1 South East. Part of the area formerly covered by London & South East Premier is now covered by a new league Regional 1 South Central.

Colchester are the 2025–26 champions.

==Format== The twelve teams play home and away matches from September through to March, making a total of twenty-two matches each. The results of the matches contribute points to the league as follows: * 4 points are awarded for a win * 2 points are awarded for a draw * 0 points are awarded for a loss, however * 1 losing (bonus) point is awarded to a team that loses a match by 7 points or fewer * 1 additional (bonus) point is awarded to a team scoring 4 tries or more in a match

The first-placed team at the end of season win promotion to National League 2 East. Two teams are relegated to either Regional 2 South East, Regional 2 Anglia or Regional 2 Thames depending on location.

Teams leaving the division included Rochford Hundred who were promoted into National League 2 South as champions along with Guernsey Raiders who won the virtual promotion play-off against Weston-super-Mare RFC, while teams relegated from the league included Bedford Athletic (Midlands 1 East), Guildford (London 1 South) and London Irish Wild Geese (London 1 South).

The teams competing in 2021–22 achieved their places in the league based on performances in 2019–20, the 'previous season' column in the table below refers to that season not 2020-21.

==2018–19== Nine of the fourteen teams participated in last season's competition. They are joined by Wimbledon who were relegated from National League 2 South, along with four promoted sides; Bedford Athletic, Brentwood, Chingford and CS Rugby 1863. Bedford Athletic had initially been promoted into Midlands Premier but were level transferred into London & South East Premier as the nearest club geographically to address an imbalance of teams in the league. Teams leaving the division included Barnes who were promoted into National League 2 South as champions along with Guernsey who won the promotion playoff, while teams relegated from the league included Southend Saxons (London 1 North), Towcestrians (Midlands 1 East) and Westcombe Park (London 1 South).

===Promotion play-off=== Each season, the runners-up in the London & South East Premier (National League 3 London & South East) and South West Premier (formerly National League 3 South West) participate in a play-off for the third promotion place to National League 2 South. The team with the best playing record, in this case Westcliff, hosted the match and beat their opponents Barnstaple 44 – 5 to win promotion to National League 2 South for the first time. This was Westcliff's first appearance in the play-offs and Barnstaple's second; in 2016 Barnstaple beat Tonbridge Juddians 31 – 30 at Tonbridge. The home team have won fifteen out of nineteen play-off matches and the south-east team have won the play-off thirteen times.

==Regional 1 South East honours== In the first season of the English rugby union league pyramid, sponsored by Courage, there was four, tier five leagues. These were London Division 1, Midland Division 1, North Division 1 and South West Division 1. In 1987 the geographical area for teams in the south-east of England was known as the ''London and South East Division'' and covered the counties of Essex, Hampshire, Kent, Middlesex, Norfolk, Suffolk, Surrey and Sussex. The league was also known as London League 1 and London 1. There were eleven teams in the league and they played each team once, giving each team ten matches.<ref name=courage92>{{cite book|editor1-last=Williams|editor1-first=Tony|editor2-last=Mitchell|editor2-first=Bill|title=Courage Official Rugby Union Club Directory 1991–92|year=1992|publisher=Football Directories|location=Taunton|isbn=1-869833-15-5|edition=4th}}</ref> This system prevailed for five seasons, and in 1992–93 the number of teams increased from eleven to thirteen.

===London Division One (1987–93)=== The original London Division One was a tier five league with promotion up to Area League 2 South and relegation down to either London 2 North or London 2 South.

===London Division One=== The top six teams from London Division One and the top six from South West Division One were combined to create National 5 South. London Division 1 was now the name of a tier six league and was one of two feeder leagues for National 5 South.
