Another swa to t&e thread!

Other than for the one extra joint (which is pretty trivial, particularly if 'accessible', do you have any reason for regarding that as the 'best solution'.
It obviously depends upon the actual situation (length and route of the indoors cable run), but installing 6mm² SWA for the indoor bits of the cable run (and terminating the SWA into whatever was at the indoor end) could be significantly more of a mission than T+E.
It gives you the option of having the RCD protection at the outbuliding end, and potentially splitting it across multiple RCDs.
Whereas if you have concealed T&E in the circuit you are forced to put the RCD protection at the source end.
If you buy a galvanised box, they look neater, don't rust, and no need to clean the paint away, to get a good earth connection.
All true - so fair enough.
However, in practice, the potential hassle of running SWA (particularly if fairly large CSA) a significant distance through a house to get to the outside might make one more inclined to think in the other direction!
