SH650,
In an ideal world, I'd agree. But in UK, the system is different. It's not common to file VFR flight plans in the way that you will be used to doing because it usually isn't a legal requirement unless crossing an international FIR border and there isn't an effective flight following service for VFR unless you also make RT contact with a relevant ATC unit. Not even for IFR flights outside CAS. Our airspace is often very congested so pilots tend to use a LARS service on an "ad hoc" basis instead and are encouraged to do so by the authority.
