Can i use old gas pipe for electrical conduit?
The floor rafters are notched at the top, which is too high to put wire through as nails could pierce them, but if i thread the cable through the old gaspipe using the existing notches, would this be 17th edition legal?

Gas pipe may have burrs inside which could damage the cable.
In some cases, it might still have gas inside :-)

No.
You could drill new holes just for the cable.
Alternatively use BS8436 cable in the notches -
You could use a different surface route, in trunking - easy to add cables to or replace vs taking up floorboards.
That is an advertising links site
I would like to use standard cheaper cable wherever possible.
I have access from underneath at the moment.
The gas piping is not copper (or I'd weigh it in)

Is it lead, as in my house? I've lugged out loads of the stuff over the years as I've had different floors up, and which I store for occasional trips to the scrappy! Also dead easy to remove of course.

Oops,
Can you not drill fresh holes away from the notched joints?
You absolutely can not use old gas piping for mains wiring.
If it is soft grey it is lead, if it is a hard grey it is block tin (and very expensive), if it is iron barrel it is still not suitable re internal burrs.
Whilst short lengths of steel conduit that are inaccessible do not need to be earthed, but a former gas pipe is something quite different. It is presumably of some length with very tight bends which are quite unsuitable for sheathed cable and absolutely unsuitable for singles cable (6491) through it because 1) damage may occur in drawing in 2) conduit must be earthed 3) conduit for singles MUST be continuous between wiring accessories which requires adapters, bushes and so on which will not fit gas pipe :-)
You could replace the gas pipe with proper steel conduit, but would need to hire a hilmor tube bender for bends and suitable tap/die set for making off re bush-entry at each end (or conduit box). It should also be earthed and that earth needs to be accessible for Inspection & Testing. Flexible steel conduit does not comply with 526-06-06, this is why people use BS8436 because it does not need special glands like SWA that must remain accessible.
A conduit is a conduit. I see no reason not to use it. Where does it say it cannot be used?

You're right. I do believe he meant:

When it's as rough on the inside as your skull?
To be fair, there is lots of space inside Drivels skull. And what is inside will not chaff anything.

It would make no difference to the electrical safety unless it is an old steel pipe.
You can knock a nail through the old lead gas pipes easier than you can through wood.

You are right. Imagine what it would be like if it was filled? I lace you lot not even trying to think. Stephen Hawkins eat your heart out.
F**king idiot! Must come from Kent or Sussex or some other boring place. There is nothing wrong with using the pipe. You just grease the cable when pulling through and then test. Duh!!!!
No reg ANYWHERE says you can't use it. Duh!!!
Well mine don't - it generates unnecessary flow resistance. However, not everyone's a perfectionist ;-)
I have reused a gas pipe for central heating radiator connection. It was conventiently the right route, and avoided ripping up (even more) floor. It's 1/2" copper tube.
