In the USA there are specific requirements for the internal volume of junction boxes, and other electrical boxes. Varies according to size and number of conductors.
There is no equivalent requirement in the UK. Certain rather vague and general requirements exist, but nothing comparable to USA code requirements for XX cubic inches. My personal view is that most UK boxes are much too small to permit of good neat workmanship and to facilitate later inspection or alteration.
That however is my view and not a statutory requirement.
