What is an FS251 certificate?

FS251, also written FS 251 or F.S. 251, is the Certificate of Fire Service Installations and Equipment. It records relevant work performed by a contractor and must reflect the actual circumstances. Obtaining a blank form or sending an enquiry does not complete an inspection or produce a valid certificate.

FS251 annual inspection requirements

FSD explains that fire service installations and equipment must be kept in efficient working order and inspected by a registered contractor at least once every 12 months. Review inspection dates, equipment condition and outstanding defects together. An old certificate alone does not establish the current condition of the premises.
