CompEx Ready is an independent online study aid for the CompEx Ex01-04 (Gas, Vapour & Mist) certification. It brings the theory, the reference tables, the diagrams and a full bank of practice questions into one clear, mobile-friendly guide, built to help you prepare for the exam.
No. CompEx Ready is an independent revision resource. It is not the official course, it is not the exam, and it is not affiliated with, endorsed by or connected to CompEx Certification Limited, EEMUA, IEC, ATEX or UKAS. You still sit your assessment through an approved CompEx training provider.
It focuses on the Ex01-04 units for gas, vapour and mist: hazardous areas, legislation and standards, the science of explosions, zones and equipment selection, the protection concepts (Ex d, e, n, i, p and the rest), installation to IEC 60079-14 and inspection to IEC 60079-17, plus a full mock exam.
No, and we would never claim that. No study aid can promise a result. What CompEx Ready does is give you the material and the practice to prepare thoroughly, the rest is down to your own study and your assessment on the day.
No. Your login is for you alone. If an account is shared, or used on several devices at the same time, access is revoked straight away and without a refund. You can appeal your case by emailing us, but the simplest advice is: don't share it. If you and a mate both want it, buy one each.
Yes. The whole guide is built to be read on a phone, a tablet or a desktop, so you can revise on site, on the move or at home.
The content reflects guidance current as of July 2026. Standards and regulations change over time, so always check the latest official standards and your training provider's material alongside this guide.
