Isn't that a bit dodgy ?

Yes, very.
In my view, this would be sufficient grounds for a supplier to
immediately disconnect your electricity supply. The HSE could
also go on to prosecute you.

if someone half reads your posting and fails to
absorb the bit about turning off the isolator then you run the risk of
electrocuting some poor sod at the sub-station fixing your power line.

Exactly. Implementing any type of transfer switch mechanism which
is not foolproof against backfeeding would be extreemly dangerous,
and should see you instantly disconnected from the electricity supply
if the supply authority finds out.

Also the comment about the earthing being take care of is not true.
You are not allowed to assume a supplier's provided earth connection
is still working when the supply isn't working.
