The service valve or bayonet connection must be within reach of the hob / stove,
so they are normally fitted next to, under or beside the appliance. You'll also
have to make the fixed hob connection with rigid pipework between the service
valve and the hob inlet. Flexible pipework is now NOT allowed with fixed
appliances.
Have a read through this site:

for more information on safe gas installations.
Thanks very much for the reply, however you've confused me a little.
At the moment I have a hob on a flexible gas hose which terminates in
a bayonet fitting on a sturdy wall mounted connector above and behind
the oven. The pipework from this to the supply is all rigid copper.
Now are you saying that the bayonet connection and the rest of the
installation as it stands is adequate 'without' a gas tap, so that I
don't need to add an isolating tap to get it up to current regs? Or do
I need an isolating tap as well as the bayonet connector? I have read
the faq but it doesn't appear to clarify this.
When you say flexible pipework not allowed do you mean the rubber
flexible hose or some sort of flexible copper connection?
The hose has been there for about ten years and is in very good
condition. What I really want to know I suppose is would it pass a
corgi inspection as it stands now? Any more help well appreciated!

If it already has a bayonet connector supplying only appliance, i.e. the hob or
the oven separately, then you don't need any more service cocks on the system.
If you are trying to feed a separate hob and oven combination from the one
bayonet connector unit, this is not allowed.
The bayonet connector will do for a service isolator for the cooker or hob
or oven it supplies.
I thought the FAQ made it clear that flexible hoses (at the end of which
is a bayonet connector) were not absolutely ruled out but difficult to
install in a way that complies with all the regs.

That's interesting - we're just refitting our kitchen and have had gas
point installed for a hob which is to be installed in a worktop. This
point is bayonet, and the built-under oven will be electric. Re-reading
all the info in this thread and skimming the FAQ again, does this mean
that the hob should *not* connect to the bayonet? We specified it was to
be for a hob rather than a stand-alone cooker, and the plumber is fully
Corgi etc...
How about a tumble dryer? We do not yet have a gas one, but are planning
one in the next few years - are these allowed to connect by bayonet
these days? At the same time as gas to the kitchen we had gas put into
the utility room, though it is just a capped-off stub pipe through the
ceiling at the moment.
Hwyl!

He must have misunderstood the requirements. Or possibly put a bayonet end
on for the time being with a view to removing it and putting in fixed
pipework later when installing the hob.
It is likely against the instructions for the hob to use a flexible hose.
The oven underneath the hob makes the use of a hose impossible.
About the only way a flexible hose could be used is if there were a
completly wasted void underneath the hob.
