Fitting a new oven

hi…im new to all this… any advice please.

im allowed to get rid of the electric oven thats in the property im renting as its not working well…

is it straightforward to replace and fit or do i need an electrician…it looks like its just a thick cable that goes into back of oven… sorry for being a bit think…

I fit my tenants own oven and disconnect if they leave. its so easy. BUT an electrician should do the work in a kichen and bathroom
