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.
The IS-04Z1 is an intrinsically safe Android smartphone designed for Zone 1 and Zone 21 work, from a North Sea deck to a gas governor kiosk at the end of a street. 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. Distribution partners for United Kingdom are being identified ahead of the Q4 2026 launch of the IS-04Z1.
Pre-launch · certification in progress · Launching Q4 2026
Short answer. United Kingdom has no appointed SAMS distributor yet: the IS-04Z1 is pre-launch (certification in progress, no certificate issued, launch planned for Q4 2026), and distributor applications are open.
For the record, no certificate exists for the IS-04Z1 today. The programme is under way ahead of a Q4 2026 launch. An operator's own vendor approval is a separate step. Certification status. Place facts reviewed October 2026.

An intrinsically safe Android smartphone designed for Zone 1 and Zone 21 hazardous areas in United Kingdom. It is pre-launch: IECEx, ATEX and NEC 500 certification is in progress ahead of the Q4 2026 launch.
Operators and classified areas drawn from the SAMS United Kingdom market guide.
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.
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.
UK crude oil and condensate production had fallen to about 630,000 barrels a day by 2024, so much of the current work is maintenance, life extension and decommissioning of mature installations.
About 98 per cent of UK oil and gas production comes from offshore fields, and the services industry in Aberdeen has been a leader in offshore technology.
A hazardous area is a place where flammable gas, vapour or combustible dust may be present. Standards divide these into zones: Zones 0, 1 and 2 for gas and vapour, and Zones 20, 21 and 22 for dust. Zone 1 and Zone 21 are the tier where an explosive atmosphere is likely to occur in normal operation, which is where the IS-04Z1 is designed to work. Anything carried in must be marked for the zone, gas group and temperature class of the area.
No certificate has been issued for the IS-04Z1 yet, so it must not be taken into a classified area until the certificate covering it exists and the site operator has accepted it.
In United Kingdom. UK classified areas fall into two patterns: a few large installations with formal permit systems, offshore and downstream, and inland Zone 1 and Zone 2 work spread thinly across gas networks, water and waste sites staffed by one or two people. The duty holder classifies each area. SAMS does not classify any area.
A distributor for United Kingdom would carry the IS-04Z1 after certification completes; the Q4 2026 launch is the planning date and no appointment has been made. SAMS reviews applicants one by one and prefers companies with their own Ex-competent technical and service staff, since certified devices must not be repaired outside approved channels.
Not today. Until the certificates are issued the IS-04Z1 stays out of classified areas, and until launch there is nothing to purchase. You can ask for the datasheet and the certification schedule, or book a safe-area evaluation unit.
SAMS has not published a price. Any figure you are offered for an uncertified Ex phone should be treated with caution; written indicative pricing is available for a defined quantity and site.
Zone 1 and Zone 21 (gas and dust) with gas group IIC and temperature class T4, subject to certification. It must not be used in a classified area before its certificate is issued and the site has accepted it.
The market guide for United Kingdom covers Aberdeen, St Fergus, Sullom Voe, Grangemouth, among others. Site-level pages are linked below.
Apply through the distributor page with your company details and the territory you cover. SAMS reviews applications company by company and has not yet granted a territory for United Kingdom.
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.
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.
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.
