Under current Part P regulations I am confused as to the use of junction boxes on lighting circuits when said boxes remain in joist voids and are therefore technically inaccessible. Can they still be used and if not what are the alternatives. The alteration I have in mind cannot use existing pendant loop in system.

If they are not accessable then use crimp connections instead of junction boxes. these I belive are fine to be left under floor boards etc...

A properly fitted crimp will not pull off or work loose.
A crimped joint covered with heatshrink is classed as a permanent joint, and therefor does not need to be accesible.
You must apply the crimps with a calibrated ratchet crimper, NOT one of those horrid 'squeeze and hope' car type crimpers.

Understood but the thing is when people now will be crimping under floorboards for a ring and leaveing the cable dangling!

and i know crimps are known as a permanant joint.

Crimps are only 99.9% permanent when the right tools is used. They are about 10% permanent when pair of pliers is used. How many DIYers have the correct crimping tool and the right type of crimps.
Faced with a similar problem the use of a double dry liner box with the joints in it and a blank face plate provides a not too obvious but accesible junction box.
