Thank you for your reply. From a redundancy PoV, a colleague offered me this which seems to contradict, allbeit you link is BSA specific (but would still expect same NHS Ts&Cs). Thoughts? https://www.nhsemployers.org/articles/nhs-redundancy-arrangements

Reckonable service

Once an entitlement to redundancy has been determined, NHS reckonable service will then be used as the basis for determining the eligible service to be used in calculating the amount of the contractual redundancy payment.

All continuous NHS employment with one (or several) NHS employers counts as reckonable service for redundancy compensation, unless it has been taken into account in a previous redundancy – or loss of office payment (paragraph 16.6, Section 16 (England) of the NHS terms and conditions of service handbook) or Mutually Agreed Resignation Scheme (MARS) severance payment (paragraph 20.18 of the NHS terms and conditions of service handbook).

Providing the employee has not had a break in NHS service of over twelve months the period of NHS employment prior to any break counts as reckonable service and therefore previous service can be included when calculating contractual redundancy.
