A gas problem is not something to ignore.
If you smell gas, suspect a gas leak or believe a gas appliance may be unsafe, your first priority should always be safety.
Many homeowners search for an emergency gas engineer because their boiler has stopped working, while others may be dealing with a potentially serious gas-safety issue.
Knowing the difference can help you take the right action.
What Should You Do If You Smell Gas?
If you smell gas or suspect a gas leak, do not treat it like an ordinary boiler breakdown.
Move away from the suspected source and follow the official gas emergency guidance appropriate to your location.
For a suspected gas emergency in Great Britain, the National Gas Emergency Service can be contacted on 0800 111 999.
If there is immediate danger to life, leave the property and contact the emergency services.
Do not attempt to investigate or repair a suspected gas leak yourself.
When Do You Need an Emergency Gas Engineer?
An emergency or urgent engineer may be required when you have a serious heating or gas-related problem that needs professional attention.
Examples can include:
- A suspected problem with a gas appliance
- A boiler that has completely stopped working
- Loss of heating during cold weather
- Loss of hot water
- A serious boiler fault
- A gas appliance behaving unusually
- A heating-system leak
- A recurring fault that leaves the system unusable
However, a suspected gas leak should be treated as a gas emergency first, rather than simply booking a normal boiler repair appointment.
Boiler Breakdown vs Gas Emergency: What’s the Difference?
This is an important distinction.
Boiler Breakdown
A boiler breakdown may mean:
- No heating
- No hot water
- A fault code
- Repeated shutdown
- Low pressure
- Unusual noises
These problems may require a boiler repair engineer.
Suspected Gas Emergency
A suspected gas leak or unsafe gas appliance is different.
If you smell gas or suspect a dangerous gas situation, follow the official emergency gas-safety procedure first.
Once the immediate emergency has been dealt with, a qualified professional can assess and repair the relevant appliance or installation where appropriate.
What Are Common Warning Signs of a Boiler Problem?
Not every boiler problem is a gas emergency, but some warning signs should prompt you to arrange professional assistance.
Look out for:
Repeated fault codes
A fault that keeps returning may indicate an underlying issue.
Unusual noises
Banging, whistling, vibrating or gurgling sounds can indicate a heating-system problem.
Loss of pressure
Repeated pressure loss should be investigated rather than constantly reset.
No heating or hot water
A complete loss of heating or hot water may require an urgent repair, particularly during cold weather.
Water leaks
Water around a boiler or heating system can indicate a plumbing or heating-system problem.
Can I Repair My Boiler Myself?
You should not attempt gas work yourself.
Gas appliances and gas-related work should be handled by appropriately qualified professionals.
The HSE states that gas safety checks must be carried out by a Gas Safe registered engineer, and gas appliance work requires appropriate competence and registration.
You may be able to perform simple user checks recommended by your boiler manufacturer, such as checking the display or controls, but don’t remove boiler covers or attempt gas repairs yourself.
What Should You Check Before Calling a Boiler Engineer?
If there is no suspected gas emergency, you can note a few useful details before contacting an engineer:
- Boiler make and model
- Any fault code displayed
- Whether you have heating
- Whether you have hot water
- Whether the boiler pressure is unusually low
- Any unusual noises
- Whether you can see water leaking
- When the problem started
This information can help the engineer understand the problem before attending.

Frequently Asked Questions
What should I do if I smell gas?
Treat it as a gas emergency. Move away from the suspected source, follow official gas emergency guidance and contact the National Gas Emergency Service on 0800 111 999 in Great Britain. If there is immediate danger, leave the property and contact the emergency services.
Can an emergency gas engineer repair a boiler?
A suitably qualified engineer can diagnose and repair relevant boiler and gas-related faults within their area of competence.
Is a boiler breakdown always a gas emergency?
No. A boiler breakdown can be a heating or appliance fault without being a gas emergency. However, if you smell gas or suspect an unsafe gas appliance or gas leak, follow emergency gas-safety procedures immediately.
How do I know if my boiler needs urgent repair?
Loss of heating or hot water, repeated shutdowns, serious leaks, persistent fault codes or unusual operation can all justify prompt professional attention. A suspected gas leak should be treated separately as an emergency.
Can I fix a gas leak myself?
No. Do not attempt to repair a suspected gas leak yourself. Follow official emergency gas-safety guidance and use appropriately qualified professionals for gas work.
