As celebrities prepare to enter the Big Brother house tonight, the launch of the latest series of the popular show marks another success for Hertfordshire’s film and TV industry.

Elstree Studios, which is currently home to the hit BBC One show Strictly Come Dancing as well as The Voice, has been undergoing a major £4.5m expansion project to clear four acres of land and construct new production facilities, paving the way for more film and TV shows to be produced in Borehamwood.

Its owner Hertsmere Borough Council received a £2m loan from Hertfordshire Local Enterprise Partnership’s Growing Places Fund with the remaining £2.5 million provided by the council from its reserves.

Hertfordshire LEP is committed to securing further growth in this key sector for the local economy, with both Elstree and Warner Bros. Studios in Leavesden seeing substantial investment in recent years.

Roger Morris, managing director of Elstree Studios, said: “The additional production facilities will ensure that Elstree Studios remain one of the UK’s most popular studios for film and television production.”

Recent film productions have included the multi-award winning The King’s Speech and it currently hosts some of the UK’s highest rating TV shows.
