Gas, Carbon Monoxide or other leaks


If you smell gas, or suspect a gas escape or carbon monoxide leakage, you should immediately do the following:

  • Check if the pilot light on a cooker, gas heater or boiler has gone out and extinguish all naked flames
  • Turn off the gas lever at the mains, which is next to your gas meter, by pulling the lever down
  • Open all doors and windows to let in plenty of fresh air
  • Do not touch switches on any lights or other electrical switches
  • Do not light any matches, Lighters or smoke in the house
  • Get everyone out of the house and stay out
  • If you need to make a call from a mobile phone – go outside the property first
  • Call the 24 hour emergency helpline of Cadent on Freephone 0800 111 999 to report the problem. They will send out an engineer to your home within the hour and make it safe. They will not carry out repairs.
  • You must telephone Aaron Services on Freephone 0800 177 7003 to report the problem and they will send out their own engineer to rectify the defect causing the problem.

Carbon monoxide detectors

The regulations for the installation of carbon monoxide detectors have changed. The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 came into force on 1 October 2022. From that date, all relevant landlords must ensure:

  1. At least one smoke alarm is equipped on each storey of their homes where there is a room used as living accommodation. This has been a legal requirement in the private rented sector since 2015.
  2. A carbon monoxide alarm is equipped in any room used as living accommodation which contains a fixed combustion appliance (excluding gas cookers).
  3. Smoke alarms and carbon monoxide alarms are repaired or replaced once informed, and found, that they are faulty.

Grand Union is currently installing carbon monoxide detectors to relevant properties as part of planned and responsive repair works. If you have any concerns or need to report a defective detector, please contact us on 0300 123 5544 and ask to speak to our Property Compliance team.
