CE and UKCA Marking for Fire Alarm Products: The Current Position
If you last paid close attention to CE and UKCA marking a couple of years ago, what you learned is probably out of date — and not in the direction most engineers expect. Great Britain was heading toward mandatory UKCA marking for construction products, including EN 54 certified fire detection and fire alarm components, with CE marking recognition due to lapse. That plan has been repeatedly extended, and the current position, confirmed by regulations that came into force in January 2026, is that CE marking continues to be recognised, with no fixed end date. This guide sets out where things actually stand, so you can answer a client's question with confidence instead of repeating something that may already be out of date.
The short version: you can still specify and fit CE-marked EN 54 certified products in Great Britain, UKCA-marked products remain equally valid, and there is currently no cut-off date forcing a change either way.
Who this is for
This is for fire alarm engineers and specifiers who want a current, accurate answer to "do I need UKCA-marked products now?" without wading through years of shifting policy announcements. The experience level assumed is basic familiarity with fire alarm components and their certification. This is a fast-moving policy area — always check the current government guidance for anything time-critical, rather than relying on any single date in this article remaining accurate indefinitely. Getting the current position right when a client first raises it is worth more than a confident-sounding answer given from memory, since this is exactly the kind of detail that has quietly changed more than once already.
Why this matters to fire alarm engineers
Fire detection and fire alarm system components — control and indicating equipment, detectors, sounders, power supplies and the rest of the EN 54 series — are construction products, and construction products placed on the market in Great Britain have to carry a recognised conformity mark under the Construction Products Regulation framework: either CE or UKCA. Which marks are currently accepted, and for how long, is not a fixed fact you learn once — it has been a genuinely moving target since the UK left the EU, which is exactly why it is worth a dedicated, current answer rather than folding it into a general EN 54 overview.
How we got here
The original post-Brexit plan was for UKCA marking to become the mandatory route for construction products in Great Britain, with continued recognition of CE marking limited to a grace period. That grace period, originally due to end, was pushed back more than once as the practical difficulties of standing up sufficient UK testing and certification capacity became clearer — a concern highlighted by an independent review of product testing and certification commissioned by government. Rather than a single clean cut-over from CE to UKCA, the practical history has been a series of extensions.
The current position
On 2 September 2024, the government confirmed it would continue recognising CE marking for construction products in Great Britain rather than let the grace period lapse. That position was then given firmer regulatory footing by The Construction Products (Amendment) Regulations 2025, laid before Parliament in November 2025 and in force from 8 January 2026, which amend the existing construction products regulations to enable continued recognition of products carrying a CE mark (including a CE mark with the accompanying UK(NI) indication) alongside UKCA-marked products. As things currently stand, per GOV.UK guidance, both CE and UKCA marking are accepted for construction products on the Great Britain market, with no fixed date set for when CE recognition will end — described as continuing until further notice, with government having also indicated any future change would come with a minimum transitional period rather than a sudden cut-off.
This is a policy position, not a permanent legal guarantee, and it sits within a wider, ongoing programme of construction product regulatory reform that has not concluded. Treat "no fixed end date" as accurate today, not as "settled forever" — and check current GOV.UK guidance before making a significant purchasing or specification decision that depends on it.
What this means on site
Practically, for the great majority of fire alarm work, this means CE-marked EN 54 certified products can continue to be specified, purchased and fitted exactly as before, without needing to specifically seek out UKCA-marked equivalents or treat existing CE-marked stock or installed equipment as somehow non-compliant. Where a manufacturer or distributor offers both CE and UKCA marked variants of the same certified product, either is currently acceptable, and the choice is largely a supply-chain or manufacturer decision rather than one that changes anything about the product's EN 54 certification or its suitability for a UK installation. From field experience, the more common practical question isn't which mark a new product carries, but reassurance for clients who have heard fragments of the UKCA transition story and are unsure whether older CE-marked equipment on their system is now "illegal" — it is not, and explaining the actual current position, briefly and accurately, is usually all that is needed.
What CE and UKCA marking are not
Neither CE nor UKCA marking is the product standard itself. EN 54 is the series of product standards a fire alarm component is tested and certified against; CE and UKCA marking indicate which regulatory framework's route to market the manufacturer has used to demonstrate that certification is in order for the Great Britain market. A product's EN 54 certification, and the performance and panel behaviour it demonstrates under test, does not change depending on which of the two marks it carries. Conflating "which mark is on the box" with "is the product properly certified" is a common source of confusion worth clearing up when it comes up with a client or on a specification. Verification of a product's actual EN 54 certification — checking the certificate, not just the mark on the housing — remains the reliable way to confirm compliance, regardless of which conformity mark happens to be printed alongside it.
Checking a product's marking status
Where it genuinely matters — a client query, a specification requirement, or simple due diligence when adding an unfamiliar product to a system — the reliable check is the manufacturer's declaration of performance and EN 54 certificate for the specific product, not the mark alone. These documents state the certification body, the certified performance and the applicable EN 54 part, and device compatibility with the rest of the system depends on that certified performance, not on whether the box happens to say CE or UKCA. Most established manufacturers can confirm a product's current certification and marking status on request, and doing that once for an unfamiliar product is a better habit than assuming from the packaging.
A timeline of the key dates
The sequence is easier to hold in mind as a short timeline than as a single rule: the original post-Brexit plan set a grace period for continued CE recognition, intended to give the market time to move to UKCA marking; that grace period was extended more than once as testing and certification capacity concerns became clearer; on 2 September 2024, government confirmed continued recognition of CE marking rather than a further short extension; and The Construction Products (Amendment) Regulations 2025, laid in November 2025 and in force from 8 January 2026, then updated the underlying regulations to reflect that continued recognition. Each of those steps kept the practical answer the same — CE marking remains accepted — while changing how firmly that position is anchored in regulation. Treat this timeline as historical context for understanding today's position, not as a prediction of what happens next.
Beyond construction products: a narrower scope than it might seem
It is worth being precise about what this covers, because "CE marking" and "UKCA marking" come up across many product categories with different rules, and conflating them is an easy mistake. This article concerns construction products specifically — the category that fire detection and fire alarm components fall under via the Construction Products Regulation framework. Other product categories, regulated under different UK product safety legislation, may have separate timelines, requirements or transitional arrangements that are not addressed here and should not be assumed to follow the same pattern. When in doubt about a product outside fire alarm and construction products, check the guidance relevant to that specific product category rather than extending the construction products position to it.
Whose responsibility the marking actually is
It is worth being clear about where responsibility for correct marking sits, mainly so it is not mistakenly assumed to be the fitting engineer's problem. Placing a construction product on the market with the correct conformity marking, declaration of performance and supporting documentation is the manufacturer's and importer's legal responsibility, not the installing engineer's. The engineer's responsibility is to fit certified, appropriately specified products and to keep reasonable records of what was fitted — not to independently verify the manufacturer's regulatory compliance chain. Where something does look wrong — a product with no visible marking at all, or documentation that does not match what is fitted — that is worth raising with the supplier or manufacturer directly rather than treated as a site-level problem to solve alone.
Safety warning: neither CE nor UKCA marking is a guarantee against counterfeit or falsely-marked products reaching the market — both marks can, in principle, be printed on a housing that has not actually gone through genuine certification. Sourcing fire alarm components through reputable, traceable supply chains, and checking certification against the manufacturer's own published records when something feels off, matters more to real fire safety than which of the two marks a genuine product happens to carry.
When not to rely on this alone
When not to use this article: do not use it as confirmation that a specific product is correctly marked and certified for a specific project, or as a substitute for checking current GOV.UK guidance before a time-sensitive purchasing or specification decision. Product-specific certification questions belong with the manufacturer and the relevant conformity assessment body, and the regulatory position described here should be reconfirmed against current guidance given how often it has changed.
Relevant standards
CE and UKCA marking are conformity-marking regimes operating under the Construction Products Regulation framework in Great Britain, not standards in themselves; the underlying product requirements for fire alarm components sit in the EN 54 series. The current legal position on continued recognition of CE marking is set out in The Construction Products (Amendment) Regulations 2025, and current guidance is maintained on GOV.UK. This is separate from the ongoing legal duty to provide and maintain an effective fire detection and alarm system, which sits under the Regulatory Reform (Fire Safety) Order 2005 regardless of which conformity mark a component carries.
A final word on staying current
Of everything in this guide, the one thing likely to change again is the date, not the mechanism — government has already shown it will extend recognition rather than force a disruptive cut-over, but it has also been clear that this is a live policy area subject to further reform. Bookmark the GOV.UK guidance rather than this article as the source of truth for anything time-sensitive.
Professional disclaimer
This is an informational resource for engineers and specifiers, current as of the date of publication. It does not replace current GOV.UK guidance, the specific product's certification documentation, or professional judgement, and this is a policy area that has changed more than once — reconfirm the current position before relying on it for a significant decision.
Related documentation
Use this alongside the current GOV.UK construction products regulation guidance, the EN 54 series for the relevant product certification, and the manufacturer's own certification documentation for the specific product being specified or fitted. Where a specification lists particular references for product marking, check they still reflect the current position described here rather than an earlier, now-superseded stage of the transition.
