What's running right now doesn't matter, it's the passive infrastructure they are more interested in. CityFibre have announced Leicester as part of the Vodafone joint venture and that's about all there is to say. What the business checker says is irrelevant. The distance from the existing ring is irrelevant.
If it soothes your soul a little have a look at the ongoing roadworks in Milton Keynes, Peterborough, etc. No-one cares that your property is 250m from the ring when they are building ducts and laterals to hundreds of premises on the way and around.
