More about United Kingdom that matters for portable equipment
United Kingdom: geography and layout
Historically most UK gas came from Morecambe Bay and the Southern North Sea off East Anglia and Lincolnshire, both now in decline, while oil comes mainly from the Central Graben of the North Sea.
United Kingdom: industry on the ground
Around 39 billion barrels of oil equivalent have been extracted from the UK Continental Shelf over four decades, and Brent crude from the British North Sea remains a major international price benchmark.
United Kingdom: rules and approvals
The UK government has legislated to keep recognising CE marking alongside UKCA for a range of product regulations, so check whether the route applies to your product category.
The term · UKEX
What “UKEX” means for a smartphone
In Great Britain, equipment for potentially explosive atmospheres falls under the Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 2016 (UKEX), with UKCA marking and UK approved bodies. Northern Ireland continues to follow the EU regime. A device with an EU-type examination certificate still needs the UK route completed separately.
UKEX is one of the four routes in the IS-04Z1 certification programme. It is in progress and no UK certificate has been issued.
In United Kingdom. In the UK the regime is UKEX, a separate route from EU ATEX, and a reviewer at an installation or terminal would ask which approval the handset carries for the area. For the IS-04Z1 UKEX certification is in progress and no certificate exists, so a UK buyer can only review the schedule and datasheet today, with the duty holder deciding acceptance.

Questions · United Kingdom
Frequently asked questions
Can we buy a UKEX mobile phone in United Kingdom today?
No. Nothing can be bought or taken into a classified area today: certification is in progress and launch is planned for Q4 2026. What is available now is the datasheet, the written certification schedule and evaluation units for safe-area use.
What does a UKEX mobile phone in United Kingdom cost?
There is no list price yet. SAMS gives indicative pre-launch pricing in writing, against a stated quantity and site, and does not commit to a lead time before certification completes.
Will the IS-04Z1 carry the UKEX route?
UKEX is part of the certification programme and is in progress. No UK certificate has been issued.
Which sites in United Kingdom does this cover?
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, among others. Site-level pages are linked below.
How will SAMS supply United Kingdom?
Through authorised distributors once certificates exist. Until then SAMS can send the datasheet and certification schedule and arrange safe-area evaluation units.
Do UK offshore installations have different rules for portable devices?
Offshore installations typically add their own permit-to-work, helicopter-transport and zone rules on top of UK law, and operators often keep lists of approved portable devices. Ask the duty holder or contractor for its approved-equipment procedure before sending devices offshore.
How does UKCA marking relate to ATEX for new equipment?
Equipment for Great Britain can be placed on the market under UKCA, using SI 2016 No. 1107 and a UK approved body, or under CE. Manufacturers usually keep both routes open if they sell in the EU too. Confirm the current labelling and importer details requirements with a UK approved body.
Can photographs from the handset support a permit or inspection record?
The 50 MP camera with PDAF is designed to give photographs sharp enough to act on, and GNSS can record where each was taken. Whether they are accepted as permit evidence is a matter for your duty holder and permit-to-work procedure.
