Your checklist
Valid photo ID matching your registration name
Bring the same ID type and spelling used at booking. Name mismatches are the most common cause of admission refusal. Confirm with the provider which ID types are accepted for this exam and whether a second form is required.
Appointment confirmation and candidate number
Print or save the confirmation email or portal screenshot showing your test date, time, and location or online proctoring link. Confirm with the provider whether a printed copy is mandatory or a digital copy is acceptable.
Know your exam format and duration
Confirm with the provider the number of questions, time limit, whether questions are multiple-choice only, and the pass mark or scoring rule. Plan your pacing from the actual numbers, not from hearsay.
Re-read the assessment standard scope for non-domestic gas work
Review the scope and definitions of the relevant non-domestic gas safety standard, including what counts as commercial or industrial premises and where domestic rules stop applying. Focus on scope boundaries, as these are frequent question topics.
Revise tightness testing and purging principles
Be able to state the purpose of strength and tightness testing, the sequence of steps, and the acceptance criteria logic. Know when a purge is required and the safety checks before and after.
Revise flueing, ventilation, and combustion analysis
Know how to check that a flue is correctly sized, terminated, and free of spillage risk, and how ventilation requirements differ for non-domestic appliances. Be able to interpret combustion readings against the appliance manufacturer's data.
Revise unsafe situations and warning notices
Know the classification logic for unsafe situations and which class requires what action, including when to isolate, label, or notify. Confirm with the provider which classification scheme the exam uses, as schemes differ by country and standard.
Bring permitted reference material only if allowed
Most closed-book exams allow nothing. Confirm with the provider whether any standard extracts, formula sheets, or calculators are permitted, and whether a basic non-programmable calculator is allowed.
Plan travel and arrive early
Aim to arrive well before the start time to allow for ID checks and settling in. For online proctoring, test your camera, microphone, and connection the day before and clear your desk area.
Prepare for calculation questions
Practise gas rate, heat input, pressure drop, and ventilation area calculations by hand so you can work without a spreadsheet. Show your working on scratch paper if the provider supplies it.
Check the provider's current candidate handbook
Rules on breaks, resits, score reporting, and permitted items change. Read the current handbook rather than relying on a course taken years ago. needs_review
Rest and hydration plan
A long multiple-choice paper rewards steady concentration. Sleep, eat, and bring water only if the provider permits drinks at the desk. needs_review
Plan the day
Confirm logistics: exact address or proctoring link, start time, arrival window, and what the provider requires you to bring. Re-read the candidate handbook sections on conduct, ID, and permitted items. If anything is unclear, contact the provider now rather than on the day.
Do one full timed practice paper under exam conditions. Mark it, then list every wrong answer by topic. Spend your remaining study time on those topics only, not on material you already know.
Work through the high-risk topics: tightness testing sequence, purge requirements, flue termination and spillage checks, ventilation for non-domestic appliances, combustion analysis interpretation, and unsafe-situation classification. For each, be able to explain the reason behind the rule, because scenario questions test reasoning, not recall.
Light revision only: skim your own summary notes and formula list. Do not start new topics. Prepare your ID, confirmation, and any permitted items in one place by the door or bag. Check travel time and any planned engineering works on transport routes.
For online proctoring, run the system check, update the browser if required, charge devices, and confirm the room meets the provider's requirements for privacy and desk clearance. Confirm with the provider what is allowed on the desk.
Eat properly and arrive with time to spare. Avoid last-minute cramming of new material; instead re-read your one-page summary of unsafe-situation actions and test sequences. Keep your ID in hand, not in a bag.
Read each question fully and watch for negatives such as 'not' and 'except'. Answer every question, since most papers do not penalise wrong answers; flag and skip long calculation items, then return to them. For scenario questions, identify the hazard first, then the required action, then the notification step.
Manage the clock: divide the total time by the number of questions to get your average pace, and check your progress at the halfway mark. If you finish early, review flagged items and check that your answer sheet or on-screen selections match your intended answers.
Note which topics felt weak while the memory is fresh. If the provider gives a provisional result, record it; if results come later, confirm with the provider how and when they will be released and what the resit policy is.
Rules to check
Bring the ID type and name spelling used at booking. If you are unsure which documents are accepted, confirm with the provider before the day; arriving without acceptable ID usually means you cannot sit the exam and may forfeit the fee.
Follow the provider's rules on permitted items exactly. Phones, smart watches, notes, and unauthorised calculators are typically prohibited in the test room; confirm with the provider what must be left outside or stored.
Breaks are usually not permitted during a timed paper, and leaving the room may end your session. Confirm with the provider whether scheduled or unscheduled breaks are allowed and how they affect your time.
Do not communicate with other candidates during the test and do not share or record question content afterwards. Reproducing exam questions breaches most providers' candidate agreements.
Scoring is normally by number of correct answers against a pass mark set by the provider, with no penalty for wrong answers. Confirm with the provider the pass mark, whether sections must be passed individually, and when results are issued.
If a technical failure occurs during an online exam, stop and contact the proctor or provider support immediately and note the time. Do not attempt to fix the problem by restarting unless instructed.
Raise any concern about a question, such as a missing data value or an ambiguous wording, through the provider's stated process rather than guessing silently; confirm with the provider how such challenges are submitted.
If you need special arrangements, request them well before the test date. Confirm with the provider the deadline and the evidence required, as late requests may not be accommodated.
