I don't think they would have a leg to stand on in that particular regard Mushy. Providing that the details in the risk assessment are still relevant to the premises and records the prescribed information, then it is suitable and sufficient. The different aspects of 'suitable and sufficient' and the 'review' are under different paragraphs in the Order. 9(1) and 9(3) respectively.
There is a clear route to ensure a review takes place, but it should be done under article 9(3). You need to review it to ensure that there have been no changes, otherwise it is just simply luck. i.e. At what point would the RP acknowledge/consider any changes? Just when challenged on the risk assessment? It is approaching a fault with article 11 at the same time, as I would be questioning the ongoing management/arrangements. If a written record of the prescribed information is required then written records of the fire safety arrangements are required, in here should it not be stated when and how things are maintained and reviewed to ensure ongoing safety?
But that being said, it doesn't say in the Order that the review has to be recorded, it is a hard one to prove unless there are clear discrepancies in the recorded information and what is actually found.
