Can I leave open connector joints at the rear of kitchen base units?

Q: We are carrying out alterations to existing circuits and have come across open connector joints at the rear of the kitchen base units, can we leave them in place?
A: No, Live conductors and terminals are required to be provided with an enclosure to ensure there can be no access to those live parts without a means of a key or a tool to prevent the risk of electric shock. There is also a further requirement that the enclosure has to prevent the spread of fire in the case of a fault.
