You can also use SVFR in Class D Zones when the weather falls below VFR minima
Which is exactly what I said in my first post, as far as the US is concerned.
However, it's not generally true in the UK, because, as FNG points out, you need 10km vis to fly SVFR if the UK unless you hold an IMCR or IR - so it would be very rare that the weather would be good enough for SVFR but not good enough for VFR.
There are exceptions to this, though. For example, an IMC-rated pilot (who is not subject to the 10km viz restriction) may elect to use SVFR if a Class D zone rather than IFR if the weather is below VFR minima. There are several reasons why he might do this - e.g. the visual approach is more expeditious than following a procedural instrument approach, or the aircraft he is flying in is not capable of flying the instrument approach (or maybe not capable of instrument flight at all).
