No actual distance is given inthe regs, but the "must be suitable for the environment" bit still applies, so it rather depends how far you expect things to get splashed. At one time NICIEC advised at least 30cm horizontal , but that was never regs. (edit they still do ) Clearly in reality the taps are rather more of a risk then the shallow end of a draining board,and maybe less than 30cm horizontal is OK if there is a large vertical offset instead. Any sink with a pullout hose in a family home with kids, and I'd be adding quite a bit more margin.
I / we'd never do this anyways... just wondered what was the regs, for this as I remember, a few years ago, a BBC investigation programme, (Dom Littelwood), had an 'electrician' inspect a cowboy job and asked about the DSO, near a kitchen sink, and the chap said it has to be "30cm" and then a post on this forum... all laughed at that 'electrician' as there is no guidance for the DSO... wondered if things had changed?
