The previous owner was using a biscuit tin lid to cover this!
Does anyone know where I could get a proper blanking plate for it? I can seem to find any back boxes which are 6x4 so, not sure what it was previously used for!!
Not sure but i think the fixing centres were same as a twin blankplate, if so you could carefully remove the tiles and make the hole smaller.
They also do Decor flanges that fit behind a twin blank plate making them slightly larger, silver version below https://www.ebay.co.uk/itm/Silver-M...gle-or-Double-Light-Switch-Plug-/292152159559
It's hard to be sure of exact measurements, but if the spacing between the fixing lugs is that of a double socket, an MK5041 cooker panel may fit the hole exactly, available on E-Bay.
