"Disconnecting" a Gas Cooker - Rules & Regs?

[Gtiracer]

Moving house so the cooker has to be "disconnected" all of which takes all somebody undoing a bayonet fitting pipe - however ridiculous it seems, I still want to do this properly and don't know if by law it has to be disconnected by a professional registered with the GAS Safe board or if I can do it myself

Well apparently it seems I don't need to call somebody in, I found a document that I believe puts me in the clear to do it myself quoting from here: http://www.hse.gov.uk/gas/landlords/1-april-2009-tb-025-contractor-responsibilities-when-disconnecting-and-reconnecting-gas-cooking-appliances.pdf

The disconnection/reconnection (at the same location) of a self-sealing appliance connector following installation is not deemed ‘gas work’ and therefore may be carried out by a non-registered person(s), for example when a home owner temporarily removes the cooker when cleaning.
