Switching from Gas to Electric?
In the UK you would need to pay a professional to remove, or make safe, the gas pipework for the hob.

You would also need to pay an electrician to do the work if you need a new circuit for the new electric hob. Whether you need a new circuit depends on the diameter of the wires in the existing circuit and some prescribed "diversity" calculations about the total loads.

On the whole, I'd pay someone else to do this and to certify it has been done to the appropriate mandatory standards.
