In the period since the publication of the Hackitt report there is an expectation on those responsible for the delivery of fire risk assessment works that ONLY persons with third party certification (TPC) and on the BAFE/IFE registers are expected to provide these reports.
The need for both external peer review and overwatch on what is provided is key to ensuring both the quality and content of the report so that, in the event of a serious on site issue all involved are fully aware of the issues and what was required.
In the event that your risk assessment coming from a non TPC source is considered insufficient and inadequate there is a serious risk that the RP will be called to account for this and both the RP and the assessor have to face the full force of the courts where there are problems.
Indeed the fire safety order 2006 makes a clear and indefatigable requirement for the RP to select their incumbent risk assessor on the basis of expertise and knowledge not cost.
There are also likely to be consequences with the clients insurance cover if, in the event of a fire they also feel the assessment to be lacking.
Be clear, use a BAFE/IFE certified assessor and have confidence that should the worst occur you have had the best guidance and support.
