Gas Safety Legislation
Understand your legal obligations under UK gas safety law. Key regulations, compliance requirements, and what they mean for your business.
Landlord Obligations
If you let a property that contains gas appliances — boilers, water heaters, cookers, hobs, or fires — the law requires you to arrange an annual safety inspection carried out by a Gas Safe registered engineer. The resulting gas safety record must be provided to your tenant within 28 days of the check and retained for a minimum of two years.
Commercial Landlords & Letting Agents
Properties let for commercial use must hold a valid gas safety certificate before tenants take occupation. The certificate must be renewed every twelve months without exception, and a copy made available to the tenant on request.
Hospitality & Food Service Businesses
Environmental Health Officers routinely request sight of a current gas safety certificate when inspecting restaurants, hotels, pubs, clubs, and takeaways. Failure to produce one can result in an improvement notice or, in serious cases, immediate closure of the premises.
Our engineers are available throughout the day, evening, and weekends to carry out inspections at a time that minimises disruption to your business, your staff, and your customers.

Scope of the Inspection — From the Meter Onwards
Downstream of the Gas Meter Only
By regulation, our engineers inspect and test the gas installation from the outlet of the gas meter onwards. Everything upstream — the service pipe and the meter itself — falls under the gas transporter's responsibility.
Included in the inspection:
- ✓ All internal gas pipework from the meter to each appliance
- ✓ Every connected gas appliance (boilers, cookers, heaters, etc.)
- ✓ Isolation valves and emergency controls
- ✓ Flue systems, ventilation openings, and extraction
- ✓ Operating pressure at each appliance
Not included:
- ✗ The incoming supply pipe before the meter (gas transporter's asset)
- ✗ The gas meter itself (owned by your gas supplier)
- ✗ Any leak or fault on the supply side of the meter
Suspect a gas leak before the meter? Call the National Gas Emergency Service on 0800 111 999 immediately — it is free and available 24/7.
Understanding Inspection Outcomes
Every appliance inspected receives one of three classifications. Knowing what each means helps you respond quickly and keep your business running safely.
Satisfactory
The appliance meets all current standards and is safe to operate. Simply schedule your next annual check and continue trading with confidence.
At Risk (AR)
The appliance falls short of current standards but poses no immediate threat to life. Continued use is at the responsible person's discretion while remedial work is arranged promptly.
- • Ventilation below recommended levels
- • Minor flue joint deterioration
- • Overdue servicing or worn seals
- • Damaged flame supervision device
Immediately Dangerous (ID)
The appliance poses an immediate risk to life. The engineer must disconnect and isolate it on the spot. Reconnection is only permitted after a qualified repair and a fresh safety inspection.
- • Active gas leak detected
- • Blocked or severed flue
- • Dangerously high CO readings
- • Flame failure device bypassed
- • Critical ventilation deficiency
Warning Notices Explained
When a fault is identified, the engineer records it formally. Here is what each notice type means for you and your premises:
At Risk Notice
Issued when an appliance does not fully conform to current standards yet is not life-threatening. The responsible person — landlord, manager, or business owner — is informed and should arrange repairs without delay.
Practical impact: The appliance may remain in use at your own risk while repairs are scheduled. However, if you decline to act, the engineer can escalate the classification to Immediately Dangerous.
Immediately Dangerous Notice
Issued when there is a direct and immediate risk to life. The engineer disconnects and caps the gas supply to the appliance without exception.
Practical impact: The appliance is labelled "DO NOT USE" and cannot be reconnected until a Gas Safe registered engineer completes repairs, confirms safe operation, and issues a new safety record.
24/7 Emergency Plumbing Across London
Our control room is staffed every hour of every day, including nights, weekends and bank holidays. When you call 07307 202652 you speak to a dispatcher — not an answering service — who takes the address, the fault and the access details, then assigns the nearest available engineer with the right parts on board. You are sent the engineer's name and a live ETA by text so you know exactly who is coming and when.
Typical arrival across central London zones is 45–60 minutes; outer boroughs and the inner M25 corridor are usually reached within 90 minutes, traffic depending. While you wait, our dispatcher will talk you through making the property safe — locating the mains stopcock for a burst pipe, isolating electrics beneath a ceiling leak, or shutting the gas off at the meter if you can smell gas.
Every engineer is employed directly (never agency), DBS-checked, carries photo ID and is covered by £5 million public liability insurance. Heating and gas work is carried out by Gas Safe registered engineers, and our water-supply work follows WRAS and Water Regulations requirements. Costs are explained and agreed with you in writing before any work starts, and every invoice is itemised line by line — no vague lump sums. All workmanship carries a written 12-month guarantee.

London Emergency Plumbing FAQs
How fast can an emergency plumber reach me in London?+
Central London call-outs are typically attended in 45–60 minutes; outer boroughs usually within 90 minutes. You get the engineer's name and a live ETA by text as soon as they are assigned.
Are you available at night, weekends and bank holidays?+
Yes — dispatch is staffed 24 hours a day, 365 days a year. Out-of-hours rates are always confirmed with you before an engineer is sent.
Are your engineers Gas Safe registered?+
Yes. All gas and boiler work is carried out by Gas Safe registered engineers, and water-supply work follows WRAS and Water Regulations requirements. Every engineer is DBS-checked and covered by £5m public liability insurance.
What should I do while I wait?+
Turn off the mains stopcock (usually under the kitchen sink) for a burst pipe or major leak, switch off electrics affected by water, and clear the area below the leak. If you smell gas, shut the gas off at the meter and open windows.
Will the work be guaranteed?+
Every job is backed by a written 12-month workmanship guarantee, with parts covered by their original manufacturer warranty.
Borough and area coverage
Engineers are stationed across the capital so there is almost always a van within a few miles of you. We cover Camden, Westminster, Kensington and Chelsea, Islington, Hackney, Tower Hamlets, Lambeth, Southwark, Wandsworth, Hammersmith and Fulham, Brent, Ealing, Haringey, Newham, Lewisham, Greenwich, Barnet, Enfield, Croydon, Bromley, Merton, Sutton, Kingston, Richmond, Hounslow, Harrow, Hillingdon, Redbridge, Havering, Barking and Dagenham, Bexley, Waltham Forest and the City of London.
Central postcodes (W1, WC1, WC2, EC1–EC4, SW1) are usually the fastest to reach because of vehicle density; suburban postcodes are covered by engineers based in the same borough rather than dispatched from a central depot, which is why out-of-zone waits stay short even overnight.
Whatever the job — an uncontrolled burst on a rising main, a soil stack blockage in a converted flat, a failed diverter valve leaving a family without hot water, or a slow leak found only with thermal imaging and acoustic tracing — the same standards apply: Gas Safe registered engineers where gas is involved, WRAS-compliant materials on water supply, £5 million public liability cover, written costs before work starts and a 12-month workmanship guarantee on completion.
