PF International Kart Circuit, also known as PFI or Paul Fletcher International, is an outdoor kart racing circuit at Brandon, near Grantham, Lincolnshire, England. It opened in 1994 and was developed by Paul Fletcher, after whom it is named. The circuit holds a CIK-FIA International A grade licence, awarded in 2011 following a track extension that increased its length to 1,382 metres. It has hosted rounds of the CIK-FIA Karting European Championship and the FIA Karting World Championship, and is the permanent venue for the Kartmasters British Grand Prix.
History
PF International was built by Paul Fletcher and opened in 1994. In 2011 the circuit underwent a major extension: a bridge and flyover section was added, increasing the track length to 1,382 metres and enabling the circuit to obtain a CIK-FIA International A grade licence. It is the only short-circuit kart track in the United Kingdom to hold this grade of licence. In the same year PFI hosted its first CIK-FIA international events.
At the 2012 CIK-FIA Karting Awards ceremony, PF International was presented with the Trophy for the Best Event of the 2012 CIK Season.
Circuit
The international layout is 1,382 metres long with 15 corners. A shorter national layout is also available for club and hire sessions.
Trent Valley Kart Club
Trent Valley Kart Club (TVKC) is a members-only kart racing club based at PF International, established in 1996.

Major events
Kartmasters British Grand Prix
The Kartmasters British Grand Prix has been held at PF International since its inaugural edition in 1996.

Winners include Lewis Hamilton, who won the 1996 edition, and George Russell, who won the 2010 edition.
