Cheers Slick, good point, I like the "all gas products must be installed by a gas registered installer" bollocks, its only when its for profit.

You can do it yourself if you know what you are doing, you have to be registered if you are making a living out of it.

Firstly, gas hobs must be plumbed in using a rigid pipe and gas tap, not a flexible hose. They are a built in item and require similar connections. Flex hoses are for slot in items such as free standing cookers and the bayonet type hose is the only gas connection that is allowed to be connected and disconnected by anyone other than a gas fitter.
If you must do it yourself, go to a plumbers merchant and ask for some 15mm copper pipe, some talon clips, some BSP threaded fittings to fit it all together and a gas tap. As has been said, you'll also need some double thickness PTFE tape as well.
You should do a leak test before you start to ensure that there are no other problems (turn all appliances off first of course) You'll need a gas fitters manometer for this and this test is done at the meter.
Then after carrying out the work you should do another leak test to ensure that what you have just worked on is also sound.
I would strongly suggest you find a gas fitter for this as they will have the equipment, the public liability insurance and the knowledge to carry out the work in a competent manner. No offence but if you think a flex hose is suitable then you've already failed on that part.

you lazy cunt. Im not going to look for you. ;)

Good man - "the gas supply pipe fitting is a 1/2 gas cylindrical male attatchment" as per the website.

I'll say that in B&Q tomorrow. Not only will I sound like I know what I'm doing I'll hopefully get a result.

I've previously fitted hobs with flexible hose. Should I be concerned?

P.S - What you wanted to say is "You're a mong, pay someone who isn't." It would have been both accurate and sensible,

Hexilite. What part of uk are u in

No, I didn't say that at all. But after 25 years fitting kitchens I have never ever seen a gas fitter (the only installation bit I don't do) use a flexible hose to connect a built in gas hob. They are flexible for a reason, it's because the cookers they are for can be moved about (although they should be chained to the wall as well).
It is Ok for a 'Competent Person' to do gas fitting (IIRC that's the usual term used) in their own house. But define competent...

Cheers BS, I did my kitchen myself, yellow lever ball isolator in an accessible location, feeding 15mm copper to the cooker, I think I have a female self sealing bayonet fitting, the cooker has the male bayonet fitting.

I should qualify the other reason for not using a flex hose on a gas hob. The hose might lay against any cooker that's underneath it inside the oven housing (which they are is almost all cases) the oven's metal outer body can get hot and that's something you don't want next to your flex hose. This is why they always use a rigid metal pipe which is clipped well away from the cooker housing to ensure they don't come into contact with each other. I'm trying to help here and it's not the NAAFI some I'm not calling anyone a mong. But I don't want anyone to blow themselves up or have a probem later on because they didn't get a bit of friendly advice. I'm not a gas fitter because I don't know enough about it. I do know enough to get someone in who is though and I always watch what they're doing and ask questions, especially if they're new to me.

That was my point in PTFEing threads. Its not rocket science, but mistakes can and do happen.

There is actually another way you can do a leak check, but it takes a lot longer to do it than using a proper manometer.
Turn all gas appliances off, leave the mains gas turned on. Check the meter reading. Leave it all for an hour and check it again. If it hasn't moved then you can be reasonably sure that there are no leaks. Turn off the gas and do the work. Do this longer test again and you should be OK. You can also buy the gas leak spray cans at any plumbers merchant to test the actual fittings you've worked on (it bubbles up when sprayed on to them if there's a leak) Or you can use soapy water in a squeezy bottle to get the same result (probably just as well actually).
The only problem with the longer test (both of them actually) is that it's bloody cold and your heating will be off for two hours. You could chance it though ...in which case we'll hear about it in the Daily Mail:
