Not aving the latest OSG or BS7671 I can only comment that a 300mm "Rule of Thumb" was advised for some distances, i.i. a starting point for refence such as for a socket out etc in proximity to a sink etc.
Obviously in a lot of kitchens it would be practically impossible/quite difficult in practice to actually stick to those dimensions rigidly and due regard might be taken to verticals as well as horizontals or even "splash barrires" etc to achieve a reasonable outcome.
Never having seen the Gas Regs nor Water Regs and/or such guidance then again I can only assume that hose "quoting them" might be correct.
