In which county are the Dragon's Den studios at Pinewood Studios located?

The Dragon's Den studios at Pinewood Studios are located in Buckinghamshire.

Pinewood Studios is a major film and television production complex in Iver Heath, in Buckinghamshire, England. Dragon's Den has used Pinewood as its studio location, placing the programme’s famous pitch room within a site better known for large-scale screen production.

The county can be confused with nearby English counties because Pinewood lies west of London and close to the Greater London boundary. Iver Heath is in Buckinghamshire, while the studio’s international reputation often causes people to identify it simply with London. The relevant location is the county, not the nearest major city.

Pinewood Studios opened in 1936 and has hosted productions across film and television. Dragon's Den’s set is a purpose-built production environment rather than an ordinary commercial office or a permanent public marketplace.
