Are fire doors required in flats?

Fire doors may be required in flats depending on the building type, layout, fire strategy and location of the door. In apartment blocks, fire doors are commonly required for flat entrance doors, communal corridors, stairwells, risers, service cupboards and protected escape routes. Internal fire doors inside individual flats may also be required in some layouts, particularly where they help protect the route to the flat entrance door.

What are the fire door regulations for flats?

Fire door regulations for flats include a combination of Building Regulations guidance, the Regulatory Reform Fire Safety Order 2005, the Fire Safety Act 2021 and, in England, the Fire Safety England Regulations 2022. The Fire Safety Act clarified that flat entrance doors opening into common parts must be considered under the Fire Safety Order. In England, the Fire Safety England Regulations also include duties around resident information and fire door checks in multi occupied residential buildings.

How often should flat fire doors be checked?

In England, responsible persons for multi occupied residential buildings over 11 metres should check flat entrance fire doors at least every 12 months and check fire doors in communal areas at least every 3 months. In other buildings, fire doors should still be checked regularly as part of ongoing fire safety management, with the frequency based on risk, use and the building’s fire strategy.

Who is responsible for fire doors in flats?

Responsibility usually sits with the responsible person or duty holder for the building. This may be the freeholder, landlord, housing provider, managing agent, building owner or employer, depending on the property. Residents also have an important role in not damaging, altering or removing fire door components, especially on flat entrance doors that protect shared escape routes.

Do fire doors in flats need smoke seals?

Fire doors in flats often need smoke seals where smoke control is required, particularly on flat entrance doors and doors protecting communal corridors, stairwells or escape routes. Smoke seals help restrict smoke movement through the gaps around a closed door, while intumescent seals expand under heat to help restrict fire spread.

When should replacement fire doors for flats be installed?

Replacement fire doors for flats should be considered when an existing door is damaged, badly fitting, missing certification, altered, warped, fitted with unsuitable hardware or unable to close correctly. Replacement may also be needed if gaps are excessive, the frame is unsuitable or repairs cannot restore the required fire performance.

Can FIS replace fire doors in occupied apartment blocks?

Yes, FIS can support fire door replacement in occupied apartment blocks and managed residential buildings. Careful planning helps minimise disruption, maintain security and manage escape routes during the works. Our team can help schedule installation or replacement works sensibly and provide suitable fire door sets for the building.

Home Fire doors Fire doors for flats

Fire doors for flats play a vital role in protecting residents, communal areas and escape routes in apartment blocks and multi occupied residential buildings. A correctly specified flat fire door can help slow the spread of fire and smoke, support compartmentation and give people more time to escape safely.

In flats, fire doors can be required in several different locations. These may include flat entrance doors, communal corridor doors, stairwell doors, service riser doors, plant room doors and, in some cases, internal fire doors inside individual flats. The exact requirements depend on the building’s layout, height, age, fire strategy and risk assessment.

At Fire Industry Specialists Ltd, we provide installation and replacement of flat fire doors for apartment blocks, managed residential buildings, leasehold properties, landlords, housing providers and property management companies across the UK. Our service focuses on complete fire door sets, compliant installation and practical support for responsible persons.

Fire door regulations in flats

Fire door regulations in flats can be more complex than in standard commercial buildings because they involve both individual homes and shared communal areas. The main principle is that fire doors should help protect escape routes, restrict smoke spread and maintain compartmentation between flats and common parts.

In England and Wales, the Regulatory Reform (Fire Safety) Order 2005 applies to the common parts of buildings containing two or more domestic premises. This means areas such as communal corridors, stairwells, lobbies, risers and shared entrances need to be considered as part of the building’s fire risk assessment.

The Fire Safety Act 2021 clarifies that, in multi occupied residential buildings, the Fire Safety Order also applies to flat entrance doors where they open into common parts. This means flat entrance doors should be considered as part of the building’s fire safety management, particularly where they protect shared escape routes.

In England, the Fire Safety (England) Regulations 2022 introduced further duties around fire doors in multi occupied residential buildings. These include:

providing residents with information about the importance of fire doors
using best endeavours to check flat entrance fire doors at least every 12 months in buildings over 11 metres
checking fire doors in communal areas at least every 3 months in buildings over 11 metres
ensuring fire doors, including self closing devices, remain in efficient working order and good repair

The exact fire door requirements for flats should always be confirmed through the fire risk assessment, building design information, fire strategy and relevant guidance. Different rules may apply in Scotland, Wales and Northern Ireland, so UK wide projects should be reviewed against the correct local framework.

What fire rating do fire doors in flats need?

The most common fire rating for flat entrance doors is often FD30 or FD30S, depending on the building and fire strategy. FD30 provides 30 minutes of fire resistance, while the “S” indicates smoke control when the door is fitted with suitable smoke seals.

However, not every building will have the same requirement. Some locations may require FD60 or another specification depending on the fire strategy, building height, compartmentation design and level of risk.

The correct rating should be confirmed before installation or replacement. It should not be assumed based only on the age of the building or what neighbouring flats have installed.

When selecting fire doors in flats, the rating must apply to the complete door set, not just the door leaf. This includes:

door leaf
frame
intumescent seals
smoke seals where required
hinges
self closing device
locks and latches
letter plate and viewer where fitted
glazing where included
threshold details
installation gaps

A door leaf labelled as FD30 may not perform as FD30 if the frame, seals or hardware are incorrect.

What makes a flat fire door compliant?

A compliant flat fire door must be suitable for the building, correctly rated and installed as a complete tested system. Compliance depends on the full door set, not one individual component.

Key factors include:

correct fire resistance rating
compatible frame or lining
suitable intumescent seals
smoke seals where required
correctly fitted self closing device
fire rated hinges
compatible locks, latches and access control
suitable letter plate and door viewer where used
fire rated glazing where included
correct gaps around the door
suitable threshold detail
product certification or test evidence
competent installation
ongoing inspection and maintenance

For flat entrance doors, smoke control is especially important because smoke can spread into communal corridors and escape routes before flames reach those areas. This is why damaged seals, poor gaps and faulty closers should be addressed quickly.

Common issues with fire doors in flats

Fire doors in flats are used every day, which means damage and wear are common. Small defects can have a major effect on performance during a fire, especially where the door protects a communal corridor or escape route.

Common issues include:

doors not closing fully
faulty or missing self closers
excessive gaps around the door
missing or damaged smoke seals
missing or damaged intumescent seals
unsuitable letter plates or viewers
incompatible locks or access control
damaged frames or thresholds
doors that have been cut or altered
poor installation
lack of certification
residents replacing doors without approval
communal doors being wedged open

These issues can compromise compartmentation and allow smoke or fire to spread more quickly. Regular checks help identify defects early and support long term fire safety compliance.
