Sitting at Step 7 of the National League system, the Northamptonshire Combination has a promotion and relegation agreement with the United Counties League. Promotion is dependent solely upon a team making an application to the UCL and meeting the requirements to do so. Rushden Rangers are the latest team to do so, following their merger with Higham Town at the end of the 2006–07 season. Other teams to have made the journey upwards include Burton Park Wanderers, Harborough Town and Woodford United, all playing in the United Counties League. Clubs in the Northamptonshire area wishing to resign from the United Counties League will be placed in this competition. The league also accommodates Reserve sides from higher-level teams in the Reserve Divisions. Bugbrooke St Michaels are the best known example, with an 'A' and 'B' side involved in the competition, in addition to their first and reserve teams.
