ok so now that we have found out what exactly passes for a joist, can anybody point to a reference for electrical wiring in a loft?
Handy and advance, there is no need for name calling, is there? Is this how you usually adress people? Advance, peddle yourself out of acting like a child. I DONT SUFFER FOOLS GLADLY BOY!

Ant - i try to run cables around the perimeter of the roof space (clipped to top of joist if necessary) and then run in the spaces between rafters to the light/ switch or whatever, again clipped towards the top of the rafter. This way if they want to lay some chipboard for storage it doesnt interfere with cables. ukgeezer
So how do you get your cables across is they cant go through the joist? Lay them on top so that they get damaged when people put things in? Smaller joist, smaller hole, whats the difference so that the hole doesnt come closer than 50mm from the top and bottom of the joist. Obviously no Engineers watching.
OK. In the absence of a 'guide to wiring in lofts' may I suggest that they should be clipped to a fixed plank at the outer edge in the loft space, the plank being notched where a cable needs to come down and the cable then clipped to a joist running 90° from the plank and on to the light fitting/whatever ? Or not ? That's, 'may I suggest, or not ?' Mr. HandyAndy - really
So, where DO they get routed? On a running board dear Lisa dear Lisa on a running board its that. Ant Most of my jobs have a board which I run & clip the cables to. At convienient point the cable(s) then go to light fitting or switch or whatever. Cables side clipped along the roof truss chord (thats the bit at the bottom). All neat & tidy

So is there actually enough room to fit the cables at the top of the joist just under where the roof will begin? Sounds like adding to exsisting circuits will be difficult on exsisting houses. Running cables up and down here and there sounds a bit long winded to me. The IEE's guide does not mention this what so ever, just mentions joist.
The answer to your query is as follows: You do not drill holes or notch into any timbers which form the truss frame work. Unlike standard floor joists, roof timbers gain their strength through trianglation, and a subsequent reliance on the other timbers for support. The loft floor joists in particular are in tension throughout their length, and any drilling will considerably weaken the integrity of the structure. Therefore, run all cables to the eves, and dip in to each accessory outlet point. Triplock
