PUWER, CE and UKCA Guide for Packaging Machinery

Current UK buyer guidance on PUWER, CE and UKCA considerations for packaging machinery and integrated production lines.

Updated 25 August 2026Practical UK guidance
Direct answer

Conformity marking and supplier documentation concern the product-supply route; PUWER concerns suitability and safe use in the actual workplace. Buyers must also manage installation, interfaces, training, maintenance, modifications and site risks.

Why this matters

In Great Britain, current government guidance gives businesses flexibility to use UKCA or recognised CE marking for machinery, subject to the applicable product regulations. The exact route depends on the market and product, so check current official guidance.

Information to collect first

  • Define the machine boundary and interfaces.
  • Check declarations and instructions match the supplied model.
  • Assess access, guarding, emergency stops and isolation.
  • Verify safety functions after installation.
  • Review modifications before implementation.
  • Retain training, inspection and maintenance records.

Recommended method

  1. 1

    Identify supply duties and workplace duties separately.

    Resolve missing documents before acceptance.

  3. 3

    Complete installation and interface assessments.

  4. 4

    Verify safety functions.

  5. 5

    Record outstanding actions.

Common mistakes to avoid

  • Assuming a CE or UKCA mark replaces PUWER.
  • Treating connected machines as independent.
  • Changing guards or software without assessment.
  • Using an old summary instead of current guidance.
  • Accepting a declaration that does not identify the machine.

Questions people also ask

Does marking replace PUWER?

No. Marking supports product-supply compliance; PUWER places duties on businesses using or controlling work equipment.

Can CE marking be used in Great Britain?

Current GOV.UK guidance gives businesses flexibility to use UKCA or CE marking for machinery in Great Britain; verify current sector guidance.

What about Northern Ireland or the EU?

Different routes apply; confirm the destination market before agreeing the declaration.

Can integration change responsibility?

Yes. The party creating an assembly may take responsibilities for the combined system.
