If it is the 12V stuff you are putting in, or stuff plugged in to a regular 13A socket, then you don't have any Part P building regulations to require a certificate, etc.
As Telectrix says, if you can put in conduit pipes, etc, it will make things so much easier if you need to replace anything, and depending on how that is done it probably avoids the whole cable-collapse in fire problem as by time a wall or similar has gone you are past caring...
