As I understand it the level of type design support varies depending on the complexities of the design in question. From CAP 632:
the level of design investigation will be determined by the three groupings, Simple, Intermediate and Complex:
• Simple: single piston engine types.
• Intermediate: multiple piston engine or turbine (single or multiple) engine types with simple mechanical flying controls or with power controls having an independent back-up system which ensures continued safe flight.
• Complex: all other types, in particular those types having features which require a high degree of specialised knowledge and equipment to maintain (e.g. types with no independent backup system to powered flying controls or with autostabilisation
systems or electronic engine controls).
And from CAP 733:
The more complex an aircraft is, the greater the level of organisational and operational support that will be required and, unless the CAA agrees alternative provision through a suitably competent design organisation, the continued involvement of the manufacturer will be required.
Although 'continued involvement' is mentioned, the level of support is dependent on the category, and the Lanc will be an 'intermediate' design while the Vulcan is a 'complex' type.
