Rules yes, but exemptions too...
''Where a UK licensed pilot is attempting to qualify for a Type Rating and can justify that he cannot complete the base training under the control of an ATO, the pilot or his/her employer may apply to the UK CAA for an exemption to allow the training to take place independently in a representative aircraft with a Type Rating Instructor qualified to instruct on the aircraft type.''

Good luck for that one
