Bit of a crappy problem here.

Our gas hob is dying, so ordered a new one which included delivery and fitting.

However, when they turned up, they said they could not fit it as the electric oven isolator switch was too close to the edge of the hob, and off they went. They did say, however, that if we changed the existing plastic isolator switch for a metal one, it would be ok and they would be able to fit the hob as planned.

Are they giving me wrong info here? As a final solution, I don't really want to have to move the switch - the house is only 12 years old, so it's not exactly old fashioned.

Any advice welcome!

They may just be obeying rules. Perhaps the plastic one can melt/burn whereas a metal one will not (you'll just burn yourself using it!)

Get a second opinion but if it's true, swap it for a metal switch. Or get an induction hob smile

It is IMO correct, though being metal or plastic, well I 've never heard of that.

Gobsmacking if your home is only 12 years old ... that seems odd.
If memory serves, a socket/cook isolator etc etc, must be a minimum 300MMs away either side of a hob and def not behind it.
Thats what we spec when we design kitchens, though I'm sure a Sparky wil be along soon to give 100% accurate info smile

Thanks.

It's not behind the hob - it's to the left of it, but within 300mm.

It's a house on a fairly large newbuild estate, so I'm guessing all of the houses will have the same problem. Just seems a little odd for such a modern house.

edit - it's a similar setup to the pic below. It's a bit grainy, but you can see the isolator to the left of the hob in this pic - ours is the same distance:

There's a maximum distance (within 2 metres) but no minimum in the regs. There is a requirement for the switch to not be behind the hob.

I've got plastic accessories about 200mm both sides of my hob with zero issues.

To be honest as the other poster states and if he's correct, and there is no minimum, we spec 300 just to be safe and well away.
Yours does look quite close, but no closer than many I have seen. Though its too close for gas IMO.

Agree, no minimum distance stated in the regs, the unwritten rule is 300mm away but this is for sinks, its more to do with the reg that says the accessory has to be adequate for the environment it is in - mytual detrimental effects of summat like that - its the same sort of reasoning why we don't put normal sockets outside. Its not accepted to site it behind the hob because it would mean reaching over the hob to switch it off.

As for changing it to a metal onw, what will that achieve? its still got plastic switches in it, if it was all metal it would go bang as soon as it was connected up. Anyway the plastic ones are flame retardant they will char but wont melt very easily.
