Fire extinguishers need to be serviced once per year. Unless they have been tampered with, used or anything unusual is noticed, in this case, they may need to be serviced by a competent company again. The service should be completed to BS5306. A competent company will be BAFE registered and will usually keep a database of the client's extinguishers so the business owner does not have to arrange a service each year. We hope this answered you questions about
How often should fire extinguishers be serviced, but if you required more info please get in touch.
