The 2007–08 National Division One was the 21st full season of rugby union within the second tier of the English league system, currently known as the RFU Championship. New teams included Northampton Saints (relegated from the Guinness Premiership 2006-07) and Esher and Launceston (both promoted from National Division Two 2006-07). After two seasons Rotherham dropped the 'Earth' from their name to return to 'Rotherham Titans' (which they had been rebranded to in 2005 for the 2005-06 season) as sponsor Earth Mortgages ran into financial difficulties and Complete Technical Services instead became the club's new sponsor. Following their relegation from the previous season, Northampton Saints won the National Division One title at the first attempt and returned to the Guinness Premiership for season 2008–09 with Chris Ashton setting what was then the English league try record of 39 tries in a season (although Phil Chesters broke this record with 70 tries in a season in tier 4, Ashton's still stands as the highest ever in tier 2). Exeter Chiefs finished in second place, and Pertemp Bees and Launceston were relegated to the 2008–09 National Division Two. (en)
