If teams are level at any stage, tiebreakers are applied in the following order: Due to the ongoing coronavirus pandemic the season was cancelled.

The season ended before all the matches were completed because of the coronavirus pandemic and the RFU used a best playing record formula to decide the final table.

The 2017–18 South West 1 East consisted of fourteen teams; five from Oxfordshire, four from Wiltshire, two from Gloucestershire and one each from Buckinghamshire, Dorset and Warwickshire.

The 2016–17 South West 1 East consisted of fourteen teams; five from Berkshire, four from Oxfordshire, three from Wiltshire and two from Gloucestershire.

The 2015–16 South West 1 East consisted of fourteen teams; four from Berkshire, three from Oxfordshire, three from Wiltshire and one each from Bedfordshire, Buckinghamshire, Dorset and Northamptonshire.

Towcestrians finished in first place and were promoted to National League 3 South West for next season, along with the runner-up and play-off winner Salisbury.

The team with the best playing record, in this case Salisbury, hosted the match and they beat their opponents Thornbury 26 – 24.
