That very much looks like it was filmed at Duxford, with the VC-10 facing the other direction than usual (similarly to part of the "Aviators" advertisement of several years ago).

Compare the yellow aircraft (Bristol Britannia) here:

with the view of the Duxford outside lineup:

The production company have simply CGI'd away the Monarch logo from the tail but left the rest of the aircraft colours the same. I suppose that having the logo of another airline next to their own, especially of one that went bust recently, wouldn't suit B(O)A(C).

Also, at about 9 seconds there is a view of the VC-10 on hard standing. Compare the concrete pattern with and the small turn-out with grass on each side in front of the camera with https://goo.gl/maps/PhLRKZmUUao at Duxford zoomed in near the VC-10's tail. Just in front of the VC-10's nose (as parked normally at Duxford) is a fence, to stop the public wandering into the hard standing for aircraft that move around under their own power. In the advertisement, this shows as a slightly fuzzy dividing line where the actual Duxford hard stand is overlaid with CGI of an airport taxiways, runways, and something a bit like 1960s Hounslow (which is much like 2010s Hounslow without the perimeter industrial sites and large hotel buildings of Heathrow today) to form the more distant scenery and background of the advertisement.

I feel quite nerdy now.
