On 1st January 2020 the UK and EU legal systems separated and the UK went in to a transition period and for that year it was business as normal as all EU directives were still valid in the UK i.e. the 2014/34/EU Atex directives was still being implemented up until the end of 2020.

Atex is not product certification but an EU legal framework to allow the sale/use of equipment within the hazardous area and the UK was no longer part of the EU legal system
Full Brexit was implemented as of 1st January 2021 UKCA Mark

  • The Atex directive and Atex certification is no longer valid in the UK
  • Notified Bodies within the UK have technically lost their status so will not be issuing new Atex certification1
  • The current requirements for Atex been transposed to the UK.2
  • UKCA mark should be used in place of the CE mark
  • UK Type certificates should be used..

The hazardous area changes are not backdated so all equipment either installed or within the supply chain can be used.
