connecting a LINDHOB10 Induction hob into existing circuit?
Discussion
We currently have a gas hob built into the kitchen workbench which sits above an electric fan assisted oven. The hob is on its way out so we are considering moving to one of the new Induction Type hobs, and the Logik LINDHOB10 seems to get excellent reviews.
Before we take the plunge I am wondering if it will be able to be used straight off the existing circuitry (if not, it will be another gas hob!).
The induction hob has a rated power consumption of 6400W - 7200w. I have been unable to find the rated consumption of the oven unit, but its a Smeg fan assisted single oven/grill.
The house was built in 1997 and has a dedicated oven circuit back to the Consumer Unit - the fuse in that circuit at the moment is just 15 Amps (I assumed it would be 30A ?). There is the usual big red switch near the oven to isolate it.
The oven circuit terminates in a three pin socket behind the oven, and the oven is currently connected by a plug into that socket (that plug is fitted with a 13 amp fuse) which is what it was like when w moved in.
1) Will I be able to fit (or have fitted by a professional if necessary)the hob without new wiring?
2) Does the consumer unit oven circuit 15A fuse have to be increased in value, and if so what is the right fuse for the circuit if I fit the induction hob?
3) Can I simply put a three pin plug onto appropriate wire for the new hob and plug in like the oven currently is (need to replace the single socket with a double socket of course) or what is the correct solution to allow the oven and hob to be wired in correctly (ie if it is a DIY job!)
Advice appreciated, thanks. Steve

7200W is about 30 amps so I would say it's very unlikely that you will be able to use the same circuit for both hob and oven, which is probably worst case 3000W (hence the 13A plug). You would need to get a new circuit run.
Definitely don't swap the socket or fuse until you know exactly what size wiring comes from your fusebox.
As it's a kitchen the work is reportable under part P etc so it will have to be a sparky that does the work.

Ok thanks so far, I acknowledge now I have to get an electrician involved, but before I take that step (only for him to come and say the cable is too small, plus intake of breath as s/he works out the price of a new run 
)if the cable is a none starter from the go I won't bother. I can't see any indication on the cable as to cross sectional area so I unscrewed it from the socket and measured it. From what I can see the cross sectional diameter of the red wire is around 4 - 5 mm (see pictures attached)which will mean an area of between 12.5 and 19.6 mm2 which according to Google will give a minimum rating of 43Amp to in excess of 57 Amp (Scale doesn't go up that far)
From the pics, does that look about right to you experts? if so I'll get a sparky in and put it safely into their hands. Appreciate your help so far. (Amendment to first post - the fuse rating for the cooker circuit is 30 Amp not 15 as stated)

4mm, 6mm or 10mm.
Looks like 4mm to me, which would explain the 30A fuse I guess.
Is that the cable from the cooker on/off switch to the cooker power socket btw ?
What goes into the cooker power socket ?
yes it is that cable from the cooker on/off to the cooker power outlet.Looks like 4mm to me, which would explain the 30A fuse I guess.

the cooker power socket is rarely used, and never for anything like a kettle.
so 4 mm would be rated at around 43 amps?
thank you.

OP, where are you buying this from? £200 retail seems pretty cheap for an induction hob, does it really have good reviews (I'm looking myself, most seem to be double the money).
And why do Pixmania (who sell cameras) have it for £170!??!
Well if I get it it will also be from Pixmania because it is the best price I could find too. I've used them before and they were excellent.And why do Pixmania (who sell cameras) have it for £170!??!
I originally saw it in Currys and was dubious as it was the cheapest (buy cheap, pay twice etc), but some online research gave it 9.3 rating out of 10 from 134 reviews which seems like a good starter. So, we thought we'd give it a punt but it all depends on the wiring being suitable. Check your pans too, they have to be magnetic for them to work, again by chance we have just bought a pan set that will work on an induction oven, thankfully !

4mm T&E is rated at 30amps, if it is surface clipped, not going through a wall with insulation. So as you have a 30A breaker then it's likely to be a 4mm cable. I reckon you'll be okay as long as you don't have all the hobs on full power and the oven on at the same time, the breaker will likely go in that case.the cooker power socket is rarely used, and never for anything like a kettle.

Great that's good enough for me to call an electrician in then, thanks for your time, I appreciate it.That cable is a 6mm. You can put a 6mm on a 40a MCB, but only on short runs. When you load the current up you will get volt drop. So to be one the safe side I would normally put a 6mm on a 32a MCB. The hob is rated at 31.3 amps. The oven rating is normally written on a sticker just inside when you open the door. If not it will be written on the back. You need to find out what size the oven is.
To be honest though if I istall an induction hob I would normally install a 10mm cable. This can then be put on a 40a MCB. You don't want to be trying to cook the christmas dinner and the oven keeps tripping out.
One other thing, I know gas hobs are a pain to keep clean, but they are far better to cook on than any electric hob I've used.

Just noticed Pixmania want £30 to deliver it, looks like currys it is then!I originally saw it in Currys and was dubious as it was the cheapest (buy cheap, pay twice etc) !
