UKCA & CE Marking of Fire Doorsets: EN 16034 Explained

What standard is used to UKCA or CE mark a fire doorset?

Conformity marking of a fire or smoke door — CE (the harmonised European mark) or UKCA (its Great Britain equivalent) — is a construction-products marking, made under the Construction Products Regulation (CPR) regime rather than under fire-safety law. The standard that describes a door's fire and smoke behaviour for that purpose is BS EN 16034. But EN 16034 never works alone. Intertek describes it as a standard that 'only extends the basic requirements for building openings protection and can only be used in conjunction with the basic product standards' — the product standard for the specific type of doorset: EN 14351-1 for external pedestrian doorsets (and windows), EN 13241 for industrial, commercial and garage doors, and EN 16361 for power-operated pedestrian doors.

Two things have to exist before a fire doorset can be marked. First, a Declaration of Performance (DoP) — the manufacturer's declaration of what the product-type actually does. Second, the mark itself, affixed to the product or to an accompanying label or data plate. This is a legal requirement, not a marketing choice: under the Construction Products Regulations 2013, a person who supplies a construction product covered by a designated standard must supply it with a declaration of performance and affix the UK marking. The gov.uk guidance on the Construction Products Regulation in Great Britain sets out the same duty for products placed on the GB market.

What does EN 16034 cover, and why can't it stand alone?

BS EN 16034 sets material-independent requirements for the fire-resistance and/or smoke-control characteristics of doorsets, openable windows and shutters, together with the ability to self-close or release. Intertek frames its scope as 'safety and performance requirements applicable to all fire resisting and/or smoke control products' used in fire and smoke compartmentation and escape routes. Crucially, it deals only with the fire and smoke properties. Everything else a door has to do — weather resistance, security, thermal and acoustic performance for an external door, and so on — sits in the cover product standard. That is why the two are always declared together.

How the fire performance is classified

The fire resistance declared under EN 16034 is tested to BS EN 1634-1 and classified to BS EN 13501-2 — the E (integrity), EI (integrity plus insulation) and EW classes, with Sa or Sm added where smoke leakage is controlled. So a marked doorset's DoP carries a European class such as E30 or EI30, not the older BS 476 shorthand. It is worth remembering that FD30 corresponds roughly to E30, not the insulated EI30 class; our fire door ratings guide and our BS 476 vs EN 1634 comparison explain the classifications and test routes in full.

Because EN 16034 is the fire-and-smoke layer only, a specification that names it must also name the base standard for the door type. In practice, for the fire doors most specifiers buy, that pairing is EN 14351-1 + EN 16034 for external pedestrian doorsets, or EN 13241 + EN 16034 for larger industrial and garage doors. A reference to EN 16034 on its own is incomplete.

Which fire doors can be conformity marked — and which cannot?

This is the point most often misunderstood on site. Conformity marking applies to a fairly narrow slice of the fire-door population. The BWF Fire Door Alliance records that 'it has been possible to conformity mark external fire rated door sets since November 2016 and it became mandatory in November 2019' — that is the EN 14351-1 + EN 16034 route. But the same source is blunt about the limit: 'conformity marking does not apply to interior door sets at this time.' The product standard for internal pedestrian doorsets (EN 14351-2) has not been cited or designated, so there is no cover standard for EN 16034 to pair with.

Warringtonfire puts the boundary in exactly these terms: 'door assemblies and internal doorsets… do not have a relevant harmonised or designated standard and cannot therefore be CE or UKCA marked,' while 'the standard for external pedestrian doorsets (EN 14351-1) and fire rated pedestrian doorsets (EN 16034) are both harmonised and designated.' A loose fire door leaf and a site-built assembly fall on the wrong side of that line too — neither can carry a mark.

Is CE marking still recognised in Great Britain?

This is the part specifiers most often get wrong, because the position has changed. The original plan was to phase CE out and require UKCA for construction products from a fixed cut-off. That was overtaken. On 2 September 2024 the government announced that CE marking will continue to be recognised for construction products placed on the GB market. The gov.uk guidance now states plainly that 'the CE mark will continue to be available when placing construction products on the market in Great Britain,' and confirms that UKCA marking also remains a valid and accepted mark (Construction Products Regulation in Great Britain, GOV.UK).

The extension is tied to wider reform of the construction-products regime. The Construction Leadership Council records the government's commitment that 'any subsequent changes to the recognition of CE marking would be subject to a minimum 2-year transitional period.' So, for now, a fire doorset placed on the GB market may carry either the UKCA mark or the CE mark. The gov.uk guidance adds one practical catch: if you affix both the UK mark and the CE mark, 'you will need valid Declarations of Performance that meet both the GB and EU CPR regimes' requirements.'

What does the Declaration of Performance and data plate tell a specifier?

The Declaration of Performance is the legal heart of conformity marking. It ties a named product-type to declared values for the essential characteristics of the cover standard, plus the fire and smoke performance under EN 16034. For a fire doorset that means the resistance to fire (the E or EI class and its period), smoke control and self-closing, sitting alongside the cover standard's other declared characteristics. If the manufacturer declares a characteristic, they are legally responsible for that value — the DoP is what a specifier, building control officer or responsible person relies on when they read the door's performance.

The mark and data plate carry a defined, checkable set of information. The gov.uk guidance sets out what a UK marking label must show:

• the last two digits of the year in which the mark was first affixed;
• the name and registered address of the manufacturer;
• the unique identification code of the product-type;
• the reference number of the declaration of performance;
• the level or class of performance declared.

Read together, those five items are the thread a specifier follows from the physical door back to its DoP, its test evidence and its manufacturer. On a marked external doorset, the checks at handover are simple: the mark and data plate are present and legible; the DoP reference on the plate matches the DoP handed over; the declared fire class (for example E30 or EI30) meets the specification for that opening; and it is the right product-type for the position. Retaining those records feeds the Regulation 38 fire-safety information package at handover.

How is conformity marking different from third-party certification?

This is the distinction that catches out specifications. Conformity marking (CE/UKCA plus a DoP) and third-party certification (Certifire, BM TRADA Q-Mark) are different things that can sit on the same door, and they answer different questions.

A DoP is the manufacturer's declaration of a product-type's performance. For fire and smoke doorsets that declaration is not a bare self-certification: fire and smoke characteristics fall under the most onerous conformity-assessment route (System 1). As Applus+ Laboratories describes it, the manufacturer must 'undergo a certification process involving the provision of samples, laboratory tests and production-control inspections carried out by' a notified body (in the EU) or an approved body (in Great Britain), which issues a certificate of constancy of performance and carries out annual surveillance. So an independent body already stands behind the mark.

Voluntary UK third-party certification schemes go further, and wider. They add ongoing audit testing on sampled products, a traceable label or plug that links each individual door to its certificate and test report, and — critically — they cover the many fire doors that cannot be conformity marked at all. The BWF Fire Door Alliance is explicit that 'in isolation conformity marking does not offer the full advantages of certification, particularly in terms of traceability, information to support maintenance and interchangeability of components.' Its guidance on third-party certification describes initial fire testing at accredited laboratories, independent factory audits and frequent testing of sampled products. Our fire-door certification schemes guide compares the schemes in depth.

How should a specifier handle marking and certification together?

Because marking and certification answer different questions, a robust fire-door specification names both and matches each to where the door goes. The sequence is straightforward:

1. For external fire and smoke pedestrian doorsets, require UKCA or CE marking to EN 14351-1 and EN 16034, with the DoP and data-plate details supplied at handover.
2. For internal fire doorsets — where marking is not available — require voluntary third-party certification (for example Certifire or Q-Mark) instead, since that is the strongest independent assurance for those doors.
3. Before ordering, check that the DoP and/or the certificate scope covers the exact configuration — leaf, frame, seals, glazing and ironmongery; a mark or certificate is only as good as the doorset or assembly it actually describes.
4. On site, protect the mark, data plate, label or plug — never overpaint or remove it, because it is the door's link to its evidence; our guide on how to identify a fire door shows what to look for.
5. Collect DoPs, certificates and data-plate records into the handover file as the doors go in, not after completion.

None of this replaces the fire-safety duties that apply once the building is occupied. Conformity marking and certification prove the product; correct installation and a maintained inspection regime keep it performing.
