Replacement shelves for my refrigerator?

Hi - I am trying to source new shelves for my fridge which have broken. It is an integrated unit and the paperwork says it is a APM 6121/6125/6115. I have removed the salad box and inside is some more information saying the unit is Schrieber AFP 6302. Could you help me to find out the nearest supplier for new shelf units - I live in Stoke on Trent, Staffordshire.

Many thanks
