Gas Safety Week 2026 runs from 14 to 20 September, and this year’s theme is simple: Take No Chances.
The week is a timely reminder that gas safety is not something to put off, ignore or attempt yourself.
As we head towards that time of year when the heating is on more and fires get switched on for cozy nights in, it’s important to act.
Appliances that aren’t regularly serviced can lead to carbon monoxide poisoning or gas leaks that could ignite.
The good news is that many risks can be reduced by taking simple checks seriously and using qualified Gas Safe experts to service your appliances every year.
Why gas safety matters
Gas is used safely in millions of homes every day, but it must be treated with care. Boilers, cookers and fires need the right installation, regular servicing and prompt attention if something doesn’t look or sound right.
Our engineers are trained to keep people and communities safe. As well as providing the region’s 24/7 gas emergency service, we invest in managing and maintaining our network of pipes that deliver gas to 2.9 million properties.
If you smell gas, suspect carbon monoxide or experience low gas pressure, our engineers will respond quickly to help keep you and your community safe. Although they do not repair appliances or pipework inside the home, their specialist training means they can assess the situation, identify potential hazards and take the right action to quickly make things safe in a gas emergency.
Expertise matters because gas work is never a DIY job. Tampering with gas supplies, meters, pipework or appliances can be extremely dangerous. It can put you, your household and your neighbours at risk. If something needs checking, repairing or moving, always call the right expert.
What you should do to stay safe
- Arrange an annual service for your boiler or other gas appliances with a Gas Safe registered engineer.
- Always check that an engineer is on the Gas Safe Register and is qualified for the type of work you need.
- Ask to see the engineer’s Gas Safe ID card before any work starts.
- Never attempt gas work yourself and never tamper with a gas meter, supply or appliance.
- Fit an audible carbon monoxide alarm and test it regularly.
- Keep vents, flues and air bricks clear so your appliances can work safely.
- Act quickly if you spot warning signs or feel unwell at home.
Know the warning signs
A healthy gas flame should burn blue. If you notice a lazy yellow or orange flame, black or sooty marks around an appliance, a pilot light that keeps going out, extra condensation or unusual smells or sounds, stop using the appliance and contact a Gas Safe registered engineer.
If you smell gas or suspect carbon monoxide, call 0800 111 999 immediately.
Be carbon monoxide aware
Carbon monoxide is often called the silent killer because you cannot see it, taste it or smell it. It can be produced when gas appliances are faulty, badly fitted or poorly maintained.
The main symptoms of carbon monoxide poisoning include headaches, dizziness, breathlessness, nausea, collapse and loss of consciousness.
If your carbon monoxide alarm sounds, or you suspect carbon monoxide, switch off appliances if it is safe to do so, open doors and windows, leave the property and seek medical help immediately.
What to do in a gas emergency
If you smell gas or suspect carbon monoxide, call the National Gas Emergency Service immediately on 0800 111 999. The line is free and available 24 hours a day.
- Open doors and windows to let fresh air in.
- Turn off the gas at the meter if it is safe to do so.
- Do not smoke, light a match, or use a naked flame.
- Do not turn electrical switches on or off.
- Leave the property and call 0800 111 999 from outside.
- Follow the advice given by the emergency adviser.

Take no chances
Gas Safety Week is a chance to pause, check and act.
Book your appliance service. Check your carbon monoxide alarm – and if you haven’t got one invest in buying one.
