Electric cooker installation help/advice required

NRand

hi all, 
I need to replace my Electric cooker which is hardwired into the wall socket behind. . I am competent enough to do it but need to know if it is a legal requirement to have an electrician do it. . Any advice?? 
Thanks

No, there isn't.  The only requirement is that anyone doing the work must be competent.  "Competent" isn't really defined anywhere.
