Warren63 wroteJust watched the full series of four on ITV Hub. As a non professional I thought it was brilliant.

Warren, yes this was a much superior representation of the facts than the usual docudrama. The subsequent programme on the Friday showed that this was not a victimless crime and even those renters who were insured stood to lose their most precious family heirlooms.
In 1983 there was an attack on the Safe Deposit in Lloyds Bank in nearby Holborn Circus. The method by which the vault door was opened was never disclosed and subsequently at least two renters sued the Bank, Chubb Alarms, and the Chubb Lock & Safe Company for £460,000 and £125,000 for the loss of jewellery and gold coins. (Guardian, July 7, 1987)
In the Hatton Garden room with a 3½ inch Chubb Anti Arc door and 20 inch Tangbar reinforced concrete walls there were 999 lockers installed, but only about half of which were rented. Of these, 73 were forced open 29 of which were without contents. How fortunate for many that only two men entered the room.
This vault which I think was built in the 1954 follows the standards of the time when the recommended thickness of reinforced concrete to match doors were 18’’ for 3½” strongroom doors. There was another recommendation however.
“In some cases it might be advisable to use a stronger wall construction than necessary for the door initially installed to allow for developments in attack or increase in the value of the target during the life of the building. A new door can be fitted with greater ease than a wall can be strengthened”
