Current legislation only requires fire doors to be fitted in HMOs where they are likely to be used as an escape route.
They must meet stringent safety requirements, and the best way to ensure compliance is to fit a certified fire door, which closes automatically and is coated with fire-resistant material.
For maximum tenant safety, although it’s not required by law, you can fit internal fire safety doors between rooms – especially between the kitchen and the rest of the home. These can help prevent the spread of fire between rooms for at least 30 minutes.
