What would be a good plan for multiple offices around the UK , review policies, RA, etc. any thoughts

Some good sound advice from Nidan. A generic risk assessment (RA) is ok if the premises are very much alike or if the activities, setting and hazards associated with the business are the same e.g. small to medium sized offices concerned mainly with office activities.

You firstly need to assess the activities that these offices carry out and assess the level of risk these activities present (as per Nidan's comments high, medium or low) and then you will need to access the risk gap for these premises (individually or as a whole). This may be carried out via a table top exercise, but there is no subsitute for visiting the offices to get a true reflection of each site/premises as from my experience there will be a wide spectrum of compliance between the offices with some falling into the different catagories (high, medium, low). Once you have completed this you will be in a position to determine whether a generic or site specific RA's are required. Although even if you decide on a generic RA you will still have to provide the facility for site specific issues to be recorded for some of the offices as there may be issues or circumstances that arise (not foreseen) in the future.

As for reviewing policies, well your risk assessment process will form part of your H&S policy when you come to review it.
