Does not affect RPOD/RILOR as long as your policy covers you for commuting to one place of work but still best to have it in case you end up doing a duty journey, even if you don't intend to submit a claim cos if you have an accident you will not be covered!!
Welsh,
It may be worth asking your ins company if they would have considered you covered for that journey as you were going to your normal place of work, although not from your normal residence, if they say you would have been covered get them to put it in writing, I assume your policy meets all the other criterea:
04.0617. Insurance Cover. It is the personal responsibility of a Service person using their private motor vehicle on an authorised duty journey to ensure that the vehicle insurance policy covers the risks set out below and is insured for business use and has the following minimum cover:
a. MMA at ODR. Service personnel using their private motor vehicle on duty journeys and claiming MMA at ODR must be insured with a financial limit of not less than £10M against claims in respect of:
(1) Damage or loss of the vehicle.
(2) Bodily injury to or death of third parties.
(3) Bodily injury to or death of any passenger.
(4) Damage to the property of third parties.
b. MMA at PCR. Service personnel using their private motor vehicle and claiming MMA at PCR must be insured with a financial limit of not less than £10M against claims in respect of 04.0617a(2) to (4).
Above is from JSP 752, if you get something in writing and your policy covers you as above as a minimum (most do) It may be worth asking your RAO to submit a case on your behalf, you never know your luck!!
