    Can someone tell me which regs apply to when to use SWA or when it's acceptable to use Hi Tuff? Common sense suggests that SWA be used whenever there's a risk of mechanical damage but my
    thoughts on risk of mechanical damage changed when a gardener I know cut through a fat TV cable that was in the middle of ivy that had grown up over twenty years.

    Decide whats required when installing and not what might have changed 20 years down the line.

    Personally I'd use Hituf if it was fixed to a wall, SWA if on the ground or under the ground.

    As the designer it's your decision!

    I like Hi-Tuf: it's lovely to work with and easy to gland, but for some reason usually more expensive than SWA.

    As Murdoch said, it's great for surface work outside.

    But underground I believe it would need 'mechanical protection' to be compliant.
