Gas safety checks
Own it, maintain it, check it
If you own the appliance, you are responsible for maintaining it and arranging an annual gas safety check. Be sure to always use a Gas Safe registered engineer. To find an engineer, go to the Gas Safe Register website, call 0800 408 5500 or use the text phone service on 0800 408 0606.

Gas safety checks for rented accommodation and landlords
If you live in rented accommodation, it’s your landlord’s responsibility to ensure an annual gas safety check is carried out. If you rent out property, you need to make sure you’re aware of your obligations to your tenants around gas safety checks, carbon monoxide and the Landlord’s Gas Safety Certificate. For more information on this, please visit our safety for landlords section.
Which appliances should be checked for gas safety?
Appliances that should be checked each year include:
- Water heaters or circulators
- Warm air heaters
- Independent space heaters
- Cooker boilers and flued cookers
- Vented and unvented hot water storage vessels
- Micro co-generation appliances
For your own safety, you should only use gas appliances in accordance with their user instructions. You should never carry out any work on them yourself, or do anything which affects the gas supply.
How to check if appliances are unsafe
If you spot any of the below, this may indicate the appliance isn’t working correctly:
- The pilot light frequently blows out
- Smoke is coming out of your appliances
- Sooty or yellow/brown staining on or around your appliances
- Excessive condensation in the room where the appliance is installed
- An orange or yellow flame in your gas fire – it should be a crisp blue colour
You could also be at risk of carbon monoxide (CO) gas building up if:
- your flue, chimney, extractor or airway is blocked or leaking. This could prevent CO from escaping so it would flow back into your property where it can build up to dangerous levels. If you have a shared flu or chimney it could even come from next door.
- you’ve recently had building work done or had new double glazing installed that’s affected your property’s ventilation
- floodwater has caused the build-up of silt or debris as this could also affect your property’s ventilation
You can find more information on this in our carbon monoxide safety hub.
If you think a gas appliance isn’t working properly, stop using it immediately. Don’t try and investigate the problem or attempt to fix a leak or a faulty appliance yourself as you could put yourself in danger.
It’s illegal for anyone to use a gas appliance if they suspect it is unsafe. Turn the appliance off and do not touch it until it has been checked by a Gas Safe registered engineer.
Gas meter safety
Gas meter safety inspections are important. We need to make sure your meter is working properly – if it’s old or damaged, it could be dangerous and it’s our responsibility to carry out a check if any risks are detected and reported. This will include a visual inspection of the gas supply surrounding the meter point.
This is the point at which gas enters your home - our meter safety inspection checks that it’s in good condition and safe to use. We also check that the emergency cut off valve is accessible and working properly, in case you need to stop the gas supply in an emergency.
What happens at a gas meter safety inspection?
- It’s very quick and easy – you don’t have to do a thing. An experienced inspector will examine your meter.
- They’ll look carefully at the emergency control valve and at all the points where gas enters and leaves.
- They’ll make sure the meter is in good order and that no gas is able to escape.
How you can arrange a gas meter safety inspection:
- Keep an eye out for a letter that asks you to arrange your gas meter safety inspection and give us a call when you get it.
- Call 0800 980 9058, 8am to 6pm Monday to Friday and 8am to 2pm on Saturdays, to book your appointment. We may monitor and/or record calls for security, quality or training purposes. Calls to 0800 numbers should be free from all mobiles and generally free from all landlines.
- If you’re not sure whether you need an inspection our call centre staff will be happy to advise you.
- If you don’t arrange your gas meter safety inspection and we aren’t able to contact you to set up and appointment, we’ll send you reminder letters.
- We’ll arrange a timeslot that’s best for you. The inspection itself doesn’t take very long.
