Have a look at the first paragraph of
CAA Visual Flight Rules (VFR) & Chart Information:Information for airspace users which is there to ensure you realise that the VFR Guide is just that: a guide.
This guidance material is intended for Pilots of VFR flights within UK Airspace below FL 195 and combines useful information from numerous sources. It is used on the understanding that it does not represent a substitute for the more comprehensive information contained in the UK AIP which should always be regarded as the authoritative source.
Then read ENR 1.2
