What should gas work RAMS include?
Gas work RAMS must cover the scope of gas work (installation, maintenance, repair, commissioning), Gas Safe registration confirmation, gas tightness testing procedures, purging methodology, combustion analysis, ventilation requirements, carbon monoxide detection, flue gas analysis, isolation procedures, and emergency actions for gas leaks including the National Gas Emergency number (0800 111 999). The RAMS must confirm that all gas work will be carried out by Gas Safe registered engineers.
Gas Work Sits Under the Most Prescriptive Safety Regime in UK Construction
The Gas Safety (Installation and Use) Regulations 1998 make it a criminal offence for any unregistered person to carry out gas work on natural gas or LPG installations. Gas Safe Register (formerly CORGI) is the only legal body for registration. The standards stack on top: BS 6891 for low-pressure pipework, IGE/UP/1 and /1B for tightness testing and purging on industrial and commercial systems, BS 6644 for commercial boilers, and the Building Regulations Part J for combustion ventilation and flueing. Carbon monoxide from poor combustion or inadequate flueing kills around 30 people a year in the UK and hospitalises hundreds. Your RAMS isn't just a site document — it's the evidence that a registered, ACS-qualified engineer applied the right procedures, in the right order, on the right scope. Understanding the legal requirements for risk assessments in the UK is the first step toward getting your documentation right.
How Riskora Helps
Riskora generates gas work RAMS covering domestic boiler installation, commercial catering gas, gas pipework alterations, meter relocation and decommissioning. The tool prompts for Gas Safe registration number, ACS category (CCN1, CENWAT, COCN1, CODNCO1 etc.), tightness testing per BS 6891 or IGE/UP/1B, controlled purging volume calculations, combustion analysis (CO, CO₂, ratio, flue gas O₂), Building Regulations Part J ventilation check, and the National Gas Emergency Service number (0800 111 999) for incident response. If you're new to RAMS, our step-by-step guide to writing a RAMS explains the fundamentals before you start generating.
Who it's for
- Gas Safe engineers installing domestic boilers and central heating systems
- Commercial gas engineers fitting catering equipment and commercial boilers
- Gas main contractors documenting service pipe installation and connection
- Maintenance engineers producing RAMS for gas appliance servicing
- Multi-trade contractors managing gas work within larger refurbishment projects

RAMS vs Risk Assessment — Key Differences
When you need a full RAMS versus a standalone risk assessment, and how the two documents work together.
Key Risks and Considerations
- •Gas explosion — from leaks during installation, testing, or purging
- •Carbon monoxide poisoning — from incomplete combustion or poor ventilation
- •Fire — from gas leaks near ignition sources
- •Burns — from working on or near live gas supplies and hot appliances
- •Asphyxiation — in confined spaces with gas accumulation
- •Manual handling — boilers, cylinders, radiators, and pipework
- •Working at height — accessing boilers in loft spaces and on roofs
- •Electrical hazards — interface between gas and electrical systems
What UK Law Actually Says
Direct quotes from the named regulations, with plain-English explanations of what each one means in practice.
Regulation 3(1), Gas Safety (Installation and Use) Regulations 1998
“No person shall carry out any work in relation to a gas fitting or gas storage vessel unless he is competent to do so.”
GSIUR Reg 3 is the bedrock — Gas Safe registration is the proof of competence, and the RAMS must reference it by registration number. Anyone working on gas without Gas Safe registration is committing an offence regardless of how good the RAMS is.
Read the source on legislation.gov.uk →Regulation 26, Gas Safety (Installation and Use) Regulations 1998
“No person shall use, or permit to be used, any gas appliance which he knows or has reason to suspect cannot be used without constituting a danger to any person.”
Reg 26 puts an active duty on the engineer to disconnect or warn against the use of an unsafe appliance found during work. The RAMS should document the AR/ID/NCS classification process for any existing appliance encountered.

Why this matters — the most recent published figures from the Health and Safety Executive and ONS.
21 CO fatalities
Annual average accidental carbon monoxide poisoning deaths in domestic settings — a meaningful share traceable to defective gas installations or work performed by unregistered persons.

Approximate annual enquiries received by the Gas Safe Register from members of the public about suspected unregistered gas work.
Source: Gas Safe Register →Worked Example: RAMS for a Commercial Catering Cooker Installation
A Gas Safe registered commercial gas engineer is installing a six-burner gas range and salamander grill in a small restaurant kitchen, replacing an existing four-burner unit. The supply is U6 metered; the gas line needs uprating from 22mm to 28mm copper to handle the increased load.
The structured builder sequences: (1) load calculation done and submitted, confirming the existing meter and pipework as upgraded will deliver adequate working pressure, (2) gas isolated at the meter with valve locked-off, ID-tagged and photographed, (3) old appliance disconnected, capped, and the disconnection witnessed by the duty manager, (4) new 28mm pipework installed, pressure-tested per IGEM/UP/1A, (5) appliances connected, tightness-tested under working pressure, (6) commissioned with combustion analyser (calibration date noted), (7) gas-safe notification submitted, customer instructions and emergency-shutoff training delivered.
Operative's commercial Gas Safe categories (COMCAT 1, 3, 5) are listed by number and expiry. Ventilation calculation per BS 6173 is referenced. Fire suppression integration with the existing extraction canopy is checked. Total RAMS time: 9 minutes. The kitchen reopened on time the following day.
Common Mistakes (and How to Avoid Them)
1. Domestic Gas Safe number used for commercial work
Why it fails: Commercial gas work requires COMCAT categories — not domestic CCN1. RAMS that reference the wrong category fail at the competence test instantly.
Fix: Match the Gas Safe category to the work type: domestic (CCN1, CENWAT, CKR1), commercial (COMCAT), LPG (LPG), pipework (CCN1).
2. No gas tightness test documented
Why it fails: GSIUR effectively requires a tightness test on any gas pipework alteration. Missing this from the RAMS is a frequent inspector finding.
Fix: Document the tightness test: pressure used, duration, pass criteria, any pressure drop observed. Per IGEM/UP/1B for domestic, IGEM/UP/1A for commercial.
3. AR/ID/NCS classification skipped on existing appliances
Why it fails: Engineers attending a job often find an unrelated unsafe appliance. GSIUR Reg 26 requires action — the RAMS should pre-empt this by stating the classification and warning-notice procedure.
Fix: Include an existing-appliance assessment section. State the procedure for AR (At Risk), ID (Immediately Dangerous) and NCS (Not to Current Standards) findings.
