Your safety is our priority

As your landlord, your safety is our priority. We’re proud to support gas safety week to promote ways of keeping gas safe!

If you have any questions or queries about keeping gas safe, please get in touch on 0800 085 7843.



1. Have all gas appliances in your property safety checked annually by a Gas Safe registered engineer.

Every year, we will carry out a gas safety check of the appliances we are responsible for – your boiler, for example.

It’s part of your tenancy agreement that you allow us access to do this. If you do not have a copy of your landlords gas safety certificate or have any questions about your gas appliances, call us on 0800 085 7843.

2. Find or check a Gas Safe registered engineer in your area


Visit and use the online search or Gas Safe Register on 0800 408 5500.

Make sure you ask to see your engineer’s Gas Safe Register ID card both front and back. The front will confirm their registration and identity, the back will confirm they can do the gas work you’ve employed them to do.


3. Know the signs! Look out for warning signs that a gas appliance isn’t working properly


  • lazy yellow flames not crisp blue flames
  • black marks/stains
  • excessive condensation


However, gas appliances can be unsafe without displaying these symptoms, so best practice is to have them checked every year.

You should let us know of any damage or signs of corrosion, such as rusting as this needs to be checked.


4. Know the symptoms! Stay aware of the symptoms of carbon monoxide poisoning –


  • Headaches,
  • Dizziness,
  • Nausea,
  • Breathlessness,
  • Collapse,
  • Loss of consciousness.


An audible carbon monoxide alarm should be fitted if there is an ‘open flue’ heating appliance such as a gas fire and back boiler, to warn you of a leak. Where we have installed an ‘open flue’ appliance, we have fitted a carbon monoxide alarm, this is tested annually.


5. Use gas appliances for their intended purposes only, e.g. do not use a cooker to heat a room.

6. Provide enough ventilation for gas appliances to burn correctly and make sure no air vents or chimneys are blocked.
