Ok own up who's done this?
I try my hardest to never do this but have, on very rare occasion installed meter tails in a cavity as the lesser of evils.
Would be interesting to hear real world thoughts on this and potential work arounds so you don't have to. I know someone on here posted a while back about some sort of capping that you could put over the tails so they couldn't be drilled. Not entirely convinced about that although I've not had a proper look at it in real life.
I had one recently where the meter box was on external wall and I needed to run an armoured from there to an internal consumer unit. Went to great trouble to avoid running the cable in the cavity and builder comes along and says why didn't you just push it up the cavity!

) - I did see some data saying soft copper could take a static load 15N /mm2 without damage (internet source, so not sure if correct). Now 1mm twin and earth would be 3mm2, so about 4.5kg max static load. But for safety, let's assume only 1 core takes all the load and for further safety divide my internet number by 2, that's about 750gm loading, not much! But I get 1m of Prymesian's finest 1mm twin and earth to weigh in at 60gm, so 3m of it seems fine for hanging undisturbed in the conduit. Hopefully
