Stand alone slot in electric cooker (Wicklewood NR18)

My disabled great neice is in her first flat in Watton and whilst I have found most things for her I am still trying to find a simple electric cooker to slot into the space that is there for it. All she would like is an easy to use (preferably white but it's not that important) electric cooker as she struggles with digital technology etc. I can collect if any kind person out there has something available. Thank you all for reading this message.
