One track in Somerset runs team building events. The appeal is that karting is a genuine leveller: seniority stops mattering the moment the lights go out.
Bristol
An indoor circuit in east Bristol running Sodi GT5 karts, with a double-level layout for drivers tall enough to use it. Being under cover, it runs the same in February as in July: the obvious pick locally if you don't want a session called off for weather.

Sydling St. Nicholas, Dorset
An outdoor circuit in the Dorset countryside near Sydling St. Nicholas, running Sodi GX390 hire karts that the operator quotes at up to 50mph. Free parking, grass picnic areas and viewing all the way round make it an easy place to bring people who aren't driving.

Dunkeswell, Devon
750 metres of smooth tarmac at Dunkeswell Aerodrome in east Devon, averaging eight metres wide: broad enough that overtaking is a real option rather than a hopeful lunge.
Gloucester
JDR Karting is an indoor karting and activity centre on the Madleaze Trading Estate off Bristol Road in Gloucester, a few minutes' walk from Gloucester Quays. The main circuit is a 300-metre tarmac track with three banked corners, where laps take around 25 seconds. Senior drivers use Sodi SR4 karts with Honda 200cc engines.
Drivers share a kart and swap over across an hour or more. Far better for building a team than everyone racing individually, and often cheaper per head because it is priced per kart.
Most operators take card on the day. Fewer will invoice a company on thirty days, and it is worth asking before you commit.
Meeting or dining space on site turns half a day into a full one and saves moving everybody twice.
Height, weight or medical limits will rule someone out. Sites with a simulator or a second activity handle that gracefully.
