As an employer, you are primarily responsible for your employee’s health and safety at work. Whether or not the workplace is safe to return to will depend on different factors such as how badly and in what way the workplace was affected by flooding.
You need to consider wider infrastructure issues (e.g. road closures, power outages or water restrictions) and the impact of these on your staff getting to and from work and whether you can be flexible.
If you need to report any flood problems (with buildings) or request a building assessment, call 0800 22 22 00.  When an assessment is done, you will receive a placard showing whether it is safe to enter the premises:
A red placard means re-entry is prohibited because the building is no longer safe.
A yellow placard means assessors have concerns about the building and have restricted entry to part of the building or have allowed temporary use of the building.
White placards means the property may have minor damage but is sufficiently safe.
You should contact the owner of the building to see whether the building is safe to return to because the owner will have to inspect the safety of the building.
