Will my cooker circuit be powerful enough for a 32 amp cooker

Put a photo of your cu ( Fuseboard) on here

If your existing hob is electric then is very likely to have a dedicated circuit which is usually a 6mm2 twin and earth flat cable and at the fuse board should be a 32/40 Apms circuit breaker. Also somewhere in the kitchen should de a cooker switch. In that case you can have your cooker easily replaced without additional works. Be aware that the work must be carried out by a qualified electrician as the circuit needs to be tested, ensure the protective device rated accordingly and the cooker isolator is in good condition. However, I do recommend a pre-assessment prior Installation.

The best option would be to have someone come out and check as even if it is on a 32a mcb there could be a undersized cable installed

The maximum demand and diversity will dictate the conductor size for your cooker. The cooker is 32A, so you need a 32A minimum circuit breaker to start. You also need to consider power loss on the cable if it's a long run. If it's a new or upgrade circuit, it will be a notifiable electrical installation and you will need an Electrical Installation Certificate (EIC).

Update a photo of the cooker connection and consumer unit . You need 6mm cable with 32A circuit breaker and cooker switch.
