Practical ATEX filling advice for your product, packs and production target

Great Britain market guide

ATEX, UKEX, UKCA and CE for filling machinery in Great Britain.

Separate workplace duties from product-market requirements, confirm the intended market and use current official guidance before the machinery marking and documentation route is fixed.

Direct answer and current-guidance boundary

In Great Britain, equipment intended for use in potentially explosive atmospheres is governed by the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016. “UKEX” is widely used as industry shorthand for the UK explosive-atmospheres conformity route, while the formal legal and marking requirements are set out in the 2016 Regulations and current government product-marking guidance. The correct route depends on the intended market, product category, manufacturer and conformity-assessment circumstances.

Government policy can change. Confirm the current official guidance when the equipment is placed on the market; this page is a project-scoping guide, not legal advice or a conformity assessment.

What is the practical difference between ATEX and UKEX for a UK filling-machine buyer?

ATEX refers to the EU framework for equipment intended for explosive atmospheres; UKEX is common shorthand for the Great Britain framework derived from the 2016 Regulations. The technical concepts are closely related, but the market, economic-operator duties, conformity route, declaration, approved or notified body involvement and marking must be checked for the actual supply.

Current Great Britain government guidance recognises CE-marked goods meeting EU requirements for many product sectors alongside the UKCA route. The dedicated guidance for explosive-atmosphere equipment states how this applies to the 2016 Regulations. A buyer should therefore request the actual conformity basis and documents rather than asking only whether a machine is “ATEX” or “UKEX”.

Does CE recognition remove the buyer’s DSEAR duties?

No. Product-market conformity and workplace explosion-safety duties are separate. DSEAR requires the employer to assess and control dangerous-substance risks, classify hazardous areas where necessary and manage the installed process. Equipment marking and documentation support that duty but do not create the site classification, ventilation design, operating procedure or overall explosion-safety verification.

Equipment and market evidence

  • Intended market and applicable regulations.
  • Manufacturer, importer and distributor roles.
  • Conformity-assessment route and body involvement where required.
  • Declaration, marking, instructions and technical documentation.
  • Stated intended use, limits and installation conditions.

Workplace and project evidence

  • DSEAR assessment and approved hazardous-area classification.
  • Product release, ventilation, extraction and static-control basis.
  • Machine location, utilities and connected equipment.
  • Operating, cleaning, maintenance and fault-recovery procedures.
  • FAT, SAT, verification and management-of-change records.

What should the purchase specification say about marking and documents?

  1. Name the intended market or markets. State Great Britain, Northern Ireland, EU/EEA or another destination rather than using “UK” as an ambiguous shorthand.
  2. Define the machinery scope. Identify the filler, pumps, controls, conveyors, capping, labelling and external safety devices that form the supplied assembly.
  3. Provide the competent classification. Include Zone, extent, gas group, temperature requirement and any external measures relied on by the equipment.
  4. State required deliverables. List the declaration, marking, instructions, certificates where applicable, drawings, equipment schedule and acceptance evidence.
  5. Control changes. Agree how changes to product, market, machine scope, components or intended use will be assessed and documented.

Common ATEX and UKEX documentation mistakes

Using UKEX as if it were one universal certificate

The required conformity procedure depends on the equipment category and route. Ask for the actual legal basis, documents and responsible parties.

Assuming CE recognition approves the installation

Recognition concerns placing products on the market. The buyer still needs competent site classification, installation, verification and operating controls.

Ignoring the final destination market

A machine intended for GB, Northern Ireland and the EU may need different declarations, body involvement or markings. Define destinations before the design is frozen.

Buyer questions

Questions buyers ask about ATEX, UKEX, UKCA and CE.

Is UKEX an official regulation name?

UKEX is commonly used industry shorthand, but the formal Great Britain legal framework is the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016. Purchase documents should cite the actual applicable regulations and conformity route.

Can CE-marked ATEX equipment be placed on the Great Britain market?

Current government guidance recognises CE-marked goods meeting EU requirements for many sectors, including the explosive-atmospheres equipment regime described in the dedicated 2016 Regulations guidance. Confirm the current position, product category and supply-chain duties at the time of placement.

Does UKCA replace the Ex marking?

No. UKCA or CE is part of the conformity-marking route, while explosive-atmosphere equipment also carries the applicable Ex-related marking and duty information. Review the complete nameplate, declaration and instructions rather than one logo.

Does an ATEX declaration replace the machinery declaration?

Not necessarily. A filling machine can fall under more than one product regime, and the manufacturer must address all applicable requirements for the supplied product. The project document schedule should identify every relevant declaration and the scope each covers.

Who is responsible if a machine is rebranded or modified?

Current government guidance explains that a business placing a product on the market under its own name, or modifying it in a way that affects conformity, may assume manufacturer responsibilities. Obtain competent legal and engineering advice for the actual supply chain and modification.

What should I send for a Great Britain ATEX filling project review?

Send the intended market, buyer and supplier roles, approved area classification, product SDS, machine and line scope, containers, utilities, acceptance requirements and the marking/documentation deliverables expected. This allows unresolved legal, technical and commercial boundaries to be identified early.
