Whatever the gas fault — a suspected leak, a dead boiler, a cooker that won’t light properly — a Gas Safe registered engineer is the only person who can legally sort it. Call 020 7183 4810 for prompt, certified gas and heating cover across Central London.
If you smell gas: turn off the emergency control valve at your meter, open windows and doors, put out any naked flames, don’t touch electrical switches, leave the property, and call the National Gas Emergency Service on 0800 111 999, then call us on 020 7183 4810.

Same day callouts across Central and West London, fixed quotes and fully guaranteed work.
Boiler faults, gas leaks, cookers, landlord certificates — all handled by one accredited team.
We cover the full range of domestic gas work across Central London: emergency leak response, boiler repairs and installations, landlord safety certificates, and gas appliance fitting. Here’s why all of it needs a registered engineer, not a general handyman.
What we cover
- Gas leak response. Rapid attendance to trace and repair a suspected leak in your pipework.
- Boiler servicing and repairs. Annual servicing, fault diagnosis and repairs on all major brands.
- Boiler installations. New combi, system or conventional boilers, fully certified.
- Landlord gas safety certificates (CP12). Annual inspections with a same-day digital certificate.
- Gas appliance connections. Cookers, hobs and gas fires, fitted and certified.
Why this is always Gas Safe registered engineer work
| The shortcut | What actually goes wrong |
|---|---|
| “My regular plumber can sort the gas side too” | Unless that plumber is individually listed on the Gas Safe Register for the specific appliance type, it’s a criminal offence for them to work on it — ask to see their ID card. |
| “I’ll just have a look myself first” | Gas faults aren’t always visible or smellable until they’re serious. Proper diagnosis needs calibrated equipment — a tightness test, a combustion analyser — not a visual check. |
| “It’s just a cooker connection, how risky can it be” | Any gas appliance connection carries the same legal requirement and the same risk of leaks or carbon monoxide if done incorrectly. |
| “Skip the certificate, just fix it quietly” | Without proper documentation, your insurance and any landlord obligations aren’t covered if something goes wrong later. |
Stop and call us now if…
- You smell gas or suspect a carbon monoxide leak
- A cooker or boiler flame is burning yellow instead of crisp blue
- Your boiler has stopped working completely, especially in cold weather
- Your landlord gas safety certificate has expired or is due
What it costs to wait
Gas faults don’t improve with time. A small leak can become a bigger one; a boiler fault ignored can turn from a simple part replacement into a full breakdown; a missed CP12 can leave you unable to serve a Section 21 notice or without valid insurance cover. Dealing with things promptly, through a registered engineer, is almost always cheaper and safer than waiting.

Frequently Asked Questions
How do I know my engineer is genuinely Gas Safe registered?
Ask to see their Gas Safe ID card — the front shows a photo and registration number, the back lists exactly which appliance types they’re qualified to work on.
How fast can you attend a gas emergency in Central London?
We prioritise gas emergencies and heating breakdowns and aim to attend as quickly as possible. Call 020 7183 4810 for a realistic window.
Can a general plumber do gas work?
Only if they’re individually Gas Safe registered for that specific appliance category — otherwise it’s illegal, whatever else they’re qualified to do.
What paperwork will I get afterwards?
Depending on the job: an invoice, a Gas Safe commissioning certificate, a combustion report, or a digital landlord CP12.
Do you handle both emergencies and planned work?
Yes — from urgent leak response to scheduled servicing, installations and landlord inspections. Call 020 7183 4810 to discuss what you need.
