Opening up holes in joist

[pc1966]

You can sometime use a jigsaw quite safely when cutting away from the wire or maybe a multi tool with a small blade???

Notching is a possibility, but this friend of mine is the sort who might try putting in screws/nails to stop floorboards creaking, so I really don't want a 45A circuit just below them!

Small notch and Nail plate

Notches!!!! Only if you have red/black VIR to wire it with.

If you do decide to make the existing holes bigger, hope you remove the cable and how easy will that be? additional joints etc.
Please say your not going to drill with the cable insitu

No, not trying that!

One of the cables needs partly moving/joining anyway as a wall socket needs moving, so I was thinking along the lines of just taking it the whole length (2-3m or so) and then bring it back along with the shower cable.

Whats wrong with notches? Sometimes it is necessary.

I'm fairly certain he isn't completely mad

I've notched out hundreds of joists over the years, but only to fit copper pipes. Nail plates won't deter a determined DIYer.

Lol just wanted to clarify

No, just slightly mad!

Ah Freddy Mercury "I'm going slightly mad, its suddenly happened"

The OSG has diagrams of positioning and depth of notches and holes allowed in joists follow those and you should be fine.
