The simple safety device is fitted to existing gas cooker pipework. When the valve is locked, the gas supply to the cooker is stopped. This eliminates the risk of the cooker being unintentionally turned on or left on, and gives peace of mind to the carer or relative that the cooker can’t be used when they leave the house or the room.

The carer or relative can easily turn the valve on using the key when the cooker is required, enabling the vulnerable person to continue to use their gas cooker safely.

We provide this free service regardless of your gas supplier. You don’t need to change energy supplier or inform your supplier of the device. If the property is rented you will need to seek the permission of the landlord to have the work done.

Before you fill out the application form, please read the information below about how we will protect customers when locking cooker valves are fitted in properties during the ongoing
Covid 19 situation.

Covid-19: Protecting you and our colleagues

The safety of our customers and colleagues is always our absolute priority and we are dedicated to keeping you safe and warm, whatever the situation. So, we have put in extra precautions to help keep you and our colleagues safe and protected.

If we need to visit your home, we’ll ask you some extra questions first:

  • Is there anyone in your property with a confirmed case of coronavirus?
  • Are you or anyone else in the property in self-isolation on medical advice or following contact with someone who has the virus?

When we arrive at your property, please help us by:

  • keeping a two-metre distance from our engineer when they arrive at your door
  • asking everyone in the property to stay in a separate room from our engineer.

Thank you for your patience and understanding at this time.
