Has anyone replaced an electric hob with an induction hob?

And how easy is it to do this?

It would be exactly the same brand and the same dimensions (at least the 'surface' bit you can see, no idea about depth). Current one is fitted into a corian worksurface with drawers underneath (that could be taken out for access to fit).

If you have done this, roughly how much did it cost to get someone to fit it (excluding the cost of buying the new hob)? Not SE, which may make a difference to labour costs.

Will depend on the induction you select.
Most electric hobs now run off a plug.
90% of induction hobs have to be hard wired to the consumer unit.
Neff & Bosch do a 600mm plug in induction, if your hob is wider it will more powerful so will need to be conect to the electric mains.
cost could cost whatever with the above considered.

It would be replacing a 600mm neff (5 years old ish) with a 600mm neff.

You need to allow more depth beneath an induction hob because of the magnets, so you may need to lose one of the drawers directly underneath the hob.

Ah, problem solved (maybe). I was googling the details of the hob on the John Lewis website and see that they will take out old hobs and out in new ones for £85.

Chances are you wont need to lose to drawer, can just drop the drawer runners as metal.
we have had a hidden top drawer on our last two kitchens with induction hobs that were hard wired.
the magnet thing was above built under ovens back along.
