A fire door is only as good as its installation. Under the Fire Safety (England) Regulations 2022, the responsible person must be able to show that fire doors are fit for purpose — and that means evidencing competent installation, not just the door’s certificate.
Q-Mark is a third-party certification scheme operated by BM TRADA, one of the UK’s longest-established certification bodies for timber and fire products. It exists because a fire door is a system, not a product: the door leaf, frame, intumescent seals, hinges, closer and gaps all have to work together, and a certified doorset fitted incorrectly will not perform to its rating.
Certification under the scheme is not a one-off badge. It is an audited, ongoing assessment of the installer — covering the competence of the operatives doing the work, the processes used on site, and the traceability of what was fitted where. Certified installers are subject to continued surveillance, including inspection of completed installations. If the standard slips, certification can be withdrawn.
The practical distinction matters. Anyone can buy a certified fire doorset. Comparatively few contractors are certified to install one, and fewer still hold certification for both installation and the associated fire stopping. That gap — between a certified product and a certified installation — is where most fire door non-compliance actually lives.
Under the Fire Safety (England) Regulations 2022, which came into force in January 2023, responsible persons for multi-occupied residential buildings have explicit duties around fire doors. In buildings above 11 metres, that includes quarterly checks of communal fire doors and annual checks of flat entrance doors, alongside the duty to provide residents with information on fire door safety.
Those duties are evidential. In an audit, following an incident, or during a building safety case review, the question is not whether you believed the doors were compliant — it is what you can produce to show it. Third-party certified installation gives you a documented chain: certified products, a certified installer, and records of what was fitted to which opening.
The alternative carries real exposure. An uncertified installation may look identical on handover and still fail under fire conditions because of an oversized gap, an incompatible hinge, or seals that were never fitted. If that door is on the escape route, the consequences are not administrative. And where the installer cannot evidence competence, the liability does not stay with them — it lands on the responsible person who appointed them.
Certified installation covers the fitting of new fire doorsets to the certified specification, with the installation itself audited under the scheme and recorded against each opening.
Inspection is the assessment of doors already in place — checking gaps, seals, closers, hinges, glazing and signage against the door’s rating, and reporting what passes, what needs attention, and what needs replacing. Inspection produces the evidence; it does not fix anything.
Remedial works are what follow: correcting the defects an inspection finds. This is where portfolios usually discover the scale of the problem, because a survey of a block frequently returns a majority of doors with at least one defect. Remedial work ranges from replacing seals and adjusting closers through to full doorset replacement where the door cannot be brought back to its rating.
Most clients need all three in sequence: survey the stock, understand the position, then plan the remediation. We can pick up any point in that cycle.
Mainlink Maintenance has worked in fire safety for over 30 years from our base at Gerards Park in St Helens. We deliver Q-Mark certified fire door installation, inspection and remedial works for housing associations, local authorities, managing agents, private landlords and commercial property owners — including Liverpool City Council, Plus Dane Housing, Johnnie Johnson Housing, HMS Works and Great Places.
That social housing and government housing experience is relevant beyond the reference list. Working under those frameworks means operating to their documentation standards, their resident liaison expectations and their audit requirements — which is the same discipline a responsible person needs for the compliance file. We handle communal doors and flat entrance doors, FD30 and FD60, single doors and phased replacement programmes across large portfolios.
We cover Merseyside, Cheshire, Greater Manchester, North Wales, Yorkshire and the Midlands for fire door work.
