You can't just buy the piece of glass. It comes together with the surrounding metal part & is very expensive. You then have a major labour job as well changing all the elements & wires over to the new glass top. Unless you can claim on household insurance to pay for someone to come & do it, otherwise most people go and buy a new stove.

I can answer this question...
How can I replace the glass hob as I have smashed it in two?
