I have been told that "BS 7671 States that the use of metal cable ties is required for cables of certain gauges". Is there anything somewhere like this in the regs?
The swizzle of SWA armour meets the requirements as written, I rather suspect it was not in the inner eye of the authors of BS7671 as an example of best practice while they earnestly sucked their collective pencils at the drafting stage.
If you are rolling your own, give it (or perhaps better a test one along side rather than the real cable) a damn good pull to be sure that it won't come undone.
builder's band looks a bit less of a hack and can be over sleeved in heat shrink if need be so as not to dig into softer cables like TV coax and so on . It can also be formed to make P or W saddle clamps. You will however need tin snips or patience.
