Really you try to avoid the use of junction boxes if possible and practicable.
In some cases it is not possible/practicable, but if cables are not jointed in a method that deems them maintenance free, the joints must be placed in a location that is easily accessible.
Personally if possible/practicable, I would install new length of cables rather than create joints, but as above not always possible/practicable to do.
Did your electrician friend of a friend, test the circuit off for you, to prove that it was safe to energise?
Even though he works as a shopping fitting sparks, is fully aware of the requirements concerning domestic installations?
Did you ever confirm the existence of 30mA RCD protection, for buried cables and socket outlets?
