The requirements for fire risk assessments in the UK were outlined in the Regulatory Reform (Fire Safety) Order 2005. However, regulations and guidelines can change, so it’s essential to check the most recent and authoritative sources for the latest information. As of my last update:

1. Frequency: The Fire Safety Order doesn’t specify a fixed interval for conducting fire risk assessments. Instead, it emphasizes that the assessment should be regularly reviewed, and whenever there is a significant change in the premises or its use.
2. Responsibility: The responsible person, often the employer or building owner, is required to ensure that a suitable and sufficient fire risk assessment is carried out. This person should also keep the assessment under review and update it as necessary.
3. Changes in Circumstances: If there are significant changes in the building, occupancy, or fire safety management procedures, a new fire risk assessment should be conducted.
4. Documentation: It is important to document the findings of the assessment, including any actions taken or planned to address the identified risks.

To get the most accurate and up-to-date information, I recommend checking with official sources such as the UK government’s official website, local fire and rescue services, or consulting with a fire safety professional. Fire safety regulations can be subject to updates, and it’s crucial to comply with the latest requirements to ensure the safety of occupants and visitors in a building.
