Beyond Fire Doors: Your questions, answered

The test is height, not storey count. Under Regulation 10 in England, quarterly checks of communal fire doors apply to multi-occupied residential buildings whose top storey is more than 11 metres above ground level. The same height threshold triggers best-endeavours annual flat entrance door checks.

Fire doors in smaller buildings still need to be maintained under the Fire Safety Order, even though this specific quarterly rule does not apply.

If this refers to the quarterly and annual fire door checks: they apply to blocks of flats in England with a top storey over 11 m, whether or not the block meets the separate definition of a higher-risk building.

The requirement to give residents information about fire doors applies to all multi-occupied residential buildings with common parts. The wider duty to assess and maintain appropriate fire precautions is also not limited to higher-risk buildings.

Start with the vacant-building fire risk assessment and how the building is actually being used, including access by security staff, maintenance workers and contractors. Check final exits and the fire doors protecting the routes those people may use, as well as doors protecting stairways, compartments, plant rooms and other relevant risks.

A door to an empty office does not automatically need the same inspection priority merely because it is on the route to a final exit; its fire-safety role determines that. Review the arrangements before areas are occupied again.

A quarterly check is a way to identify deterioration; it does not mean every defect has an automatic three-month repair deadline. Record findings, prioritise defects by their effect on the door’s performance, commission competent repairs as soon as reasonably practicable, and track outstanding work and any interim measures.

The 3–4 mm figure is a common benchmark for gaps at the top and sides, but the correct limit depends on the doorset’s specification. Seasonal movement does not create a blanket allowance to exceed it.

Government guidance also distinguishes these basic quarterly checks from a detailed assessment of whether a door’s original specification is adequate.

Assess the whole doorset in its location: door leaf, frame, fit, gaps, closer, seals where required, glazing, ironmongery, damage and any alterations. Seek installation or product records where available and use a competent fire door specialist where performance is uncertain.

Lack of a certificate alone is not a reason to replace an existing door: government guidance expressly says an older door can remain adequate if its fire performance suits the risk and it is in good condition. Where adequacy cannot be established or defects cannot be suitably repaired, replacement may be necessary.

Age or lack of modern certification does not automatically require replacement. The current government guidance says that, in many circumstances, a door that met the standards applicable when the building was built or the door was made may remain adequate if it is undamaged, fits properly and provides protection appropriate to the risk.

A Victorian door still needs a building-specific assessment: its construction, any glazing or panels, frame, gaps, closing action, alterations and the escape route it protects all matter. It is not an automatic exemption for every historic door.

This is mostly down to poor maintenance in our experience, as well as general wear and tear in the use of the door.

That is a real budgeting challenge, particularly across large portfolios. A useful first step is to separate urgent performance defects from planned maintenance, then ask a competent specialist for an itemised repair-versus-replacement recommendation for each door.

Comparable, clearly specified quotations and a tracked programme help avoid replacing doors that can be properly repaired while ensuring significant defects are addressed promptly.

Keep a door-by-door record of inspection invitations, dates, methods of contact, appointments offered, reminders, access refusals, inspection results and follow-up on defects. Offer practical access options and explain why the check matters.

Where access is persistently refused, record the escalation considered under the lease and obtain advice on the next step.

For buildings over 11 m, the legal wording for the annual check is “best endeavours”; government guidance requires a record of the steps taken and any doors for which access was not granted. Ownership of a door does not remove that checking duty from the Responsible Person.

Poor installation and a lack of effective sealants between the frame and the structure are the most often causes of frame adjustments, as well as day-to-day wear and use of the fire door itself.

There is no single interval that covers every cause-and-effect function. Agree a documented testing programme with the competent fire alarm and relevant system contractors, covering the interfaces and functions appropriate to that building, as well as testing after alterations.

If the building has changed, compare the current layout and systems with the fire strategy, cause-and-effect matrix, commissioning records and what happens on site. Commission a competent review where those records are missing or disagree; a successful routine alarm test alone does not establish that the programmed response is still correct.

Ask the assessor to identify the system type, the applicable standard and why monthly testing is appropriate for that building. Weekly user tests are normally recommended for a BS 5839-1 fire alarm system; monthly checks may relate to a different system or function, such as a smoke control check. Record any agreed departure and keep routine user testing separate from professional servicing.

First establish what system is installed and why. For a communal system designed to BS 5839-1, weekly user testing is the normal recommendation, alongside periodic servicing.

The building’s small size or budget does not itself make monthly testing equivalent. A routine weekly test may be carried out by a suitably instructed person; if a different arrangement is proposed, obtain competent, building-specific advice, record the reasons and review the fire risk assessment.

Start by gathering the information that is available, such as building plans, fire risk assessments, installation and commissioning records, cause-and-effect information, and inspection and maintenance reports. This helps establish what protection was intended, even if there is no formal fire strategy document.

For active systems such as fire alarms, smoke control, sprinklers and automatic door releases confirm what each system is designed to do, how the systems interact, and whether testing and maintenance demonstrate that they operate correctly.

For passive measures such as compartment walls, fire stopping and fire doors identify the compartment lines and inspect their condition, particularly where alterations or service installations may have affected them.

Where the intended design cannot be established, or the records conflict with what is on site, a competent fire engineer should review the building and document the basis on which its fire precautions and evacuation strategy are being managed. The fire risk assessment can then identify any immediate risks and actions while that work is completed.

It depends on the nature, extent and location of the defects and whether the remaining measures still support the strategy.

Have a competent fire risk assessor review the evidence promptly, set out repairs and any interim measures, and explicitly advise whether stay put remains appropriate.

Where compartmentation cannot adequately protect residents, a change in evacuation arrangements may be required, but it should be properly planned and communicated rather than assumed to follow from every isolated defect.

Yes. Include accessible fire stopping in routine building inspections and fire risk assessment reviews, with particular checks after cable, pipe, refurbishment or other works that penetrate compartment lines. Keep a record of penetrations and repairs, and require competent installers to provide evidence of the system used.

The inspection programme should reflect the building and the likelihood of disturbance; there is no universal quarterly inspection rule for all fire stopping.

Lithium-ion batteries can enter thermal runaway if damaged, faulty, overheated, short-circuited or charged incorrectly; heat generated inside the battery can then escalate rapidly. Fairy lights may use mains power, disposable batteries or rechargeable batteries, so check the label or battery compartment rather than assuming they contain lithium-ion cells. Use the correct power supply, avoid damaged wires or batteries, and follow the maker’s instructions.

No not yet – we all know and accept that lithium-ion batteries are an issue and extend beyond car, scooters and bikes, we just don’t have the evidence yet.

The availability of an approved plug-in product does not mean every balcony is suitable for it. Managing agents should establish an approval process before installation, checking the balcony and external wall construction, fixings, electrical arrangements, escape routes, insurance and any remediation plans. Record approved installations and consider their effect on the fire risk assessment, building safety case and emergency information.

London Fire Brigade advises against installation on combustible external wall systems or timber balconies. A system with battery storage needs particular scrutiny.
