I don't know how it's normally done in the UK, but over here you should have:
A dedicated radial circuit for the range and the fryer rated appropriately and connected to its own MCB.
There should be an isolating switch, usually a large red rotary type that's very easy to turn, identify and reach located far enough from the fryer / range to allow someone to isolate the power without being burned should there be a fire.
(these need to be clearly labled!)
Lighting should be on its own 6A or 10A radial.
And, if it were here anyway, socket outlets would be on another radial (or number of radials) protected by 16 or 20A MCB + RCD.
In an area like a chip shop, it would also be quite important that the electrical equipment should be capable of surving mechanical damage e.g. being hit with something heavy.
So, any surface mounted cable should be in steel conduit and any fittings should be metal clad or of industrial quality plastic and definitely not the normal white brittle switches and sockets you find in residential and office installations.
There should be no fittings / fixtures or wiring anywhere behind or near the fryer and precautions should be taken to ensure that no cabling / fittings are likely to be heat damaged / fire damaged or exposed to a lot of steam / condensation or splashes...
(Common sense applies!)
If the fryers / ranges / ovens are designed to be moved for cleaning, they would usually be connected using CEEform industrial plugs (rated appropriately)
