Connecting A Fitted Electric Oven & Gas Hob

[Greenside]

I have a 5 burner hob unit and a fan assisted oven designed to fit underneath the worktop. The hob requires power for the ignition system and the oven needs some to work at all (duh).

The electrician has provided power on a dedicated circuit using 4mm² wires and this has been led through the back of the housing where it will be installed. In the UK the supply to the oven would have to be via a double pole switch of the appropriate rating (15A?) with an uninteruptable ground connection and the fitting instructions for the oven bear this out. I could mount one in an adjacent cabinet but the wires now in place are not long enough so I'd have to use a junction box (I have some Crabtree UK type) and then run to the switch. My questions are:

1. Then what? Removal of the oven for maintenance of it or the hob is likely at some point - should I just wire it directly to the switch and disconnect it for removal or is it OK to go from the switch to a normal outlet and fit plugs to both appliences which might be a bit untidy but make service a doddle.
2. Gas to the hob: The cylinder will be under the counter with an alarm fitted to detect leaks but there's a run of about 2m from the hob to the cupboard where it will sit. The last house I was in had the stove connected to the cylinder by a long and flimsy looking flexible plastic pipe and although we never had a leak I'm wondering if something more robust can be found. Copper pipe? Do they have compression fittings here that would allow me to make safe connections?

Edit: Oops! I see the thread title has a misleading typo which I can't correct via the edit system. Apologies to any Electriwitches who may have opened the thread in error.

I can tell you what we have that's no trouble.

We have a electric ignition system for gas rings with a cable via an ordinary two way switch which i can undo and release the wires.

The electric hot plate has a 30 amp safety breaker switch, which has a cover that can be taken off and the wire to can be released if I want the unit out.

I don't think I would put a plug on an electric oven if I had one.

Our gas is supplied from a cylinder 2.3 M away with a reinforced plastic tube fitted to the connections.

We have had no trouble with this except if we don't turn the gas pressure off at the cylinder it tends to leak slightly from the hob rings.

I've fixed the thread title electriwitches forming an 'electricoven' indeed

In the absence of proper 'Cooker Control Units' here we need to find a safe alternative.

What is the power rating of your oven? If it's less than 3kW or so you could use a plug / socket combination behind the unit to permit maintenance disconnection. I would use a Euro (Schuko) connector as they are more robust than the regular flat blade type. Having an oven on a plugtop is quite allowable under UK regs.

Just spur a regular outlet for the cooktop ignition.

20A breaker in the consumer unit and you're good to go.

If you really want local isolation then a 20A switch would be appropriate, may not be readily available, but 2 pole breakers are cheap and available with nice housings, just use one as a switch.
