The Seth Rogan written film took £1.2 million on its second weekend of release which brings its total gross in the UK to £5.3 million.
Highest new film of the week is the remake of Ben-Hur which lands at number 2 this week with a debut gross on £1.05 million.
It hard to judge how this compares to the 1959 classic as attendance figures are hard to come by but it is considered a classic and it would have grossed nearly £100 million in todays money.
Also new this week is the US smash hit Don't Breathe at number 4 and Kubo and The Two Strings at number 5, Hell or High Water at number 7.
The BFG is the longest stay on the box office this week having been around for 8 weeks while Finding Dory is the highest total grossing movie with £40.8 million.
