Flood advice

What should I do if I have been flooded already?

If you have been flooded and it is safe to do so, please turn off your gas supply at the gas meter.

Do Not switch off your gas supply if your gas meter is under water or the meter is in the cellar. The gas pressure in the pipes should keep the water out of the gas pipes in your home. (Unless you have an existing gas leak.

When you return to a property that has been flooded

Once the flood waters have left your home and it is safe to return to your property, if you can smell gas, experience poor pressure or have no gas please contact the free national gas emergency line 0800 111 999* and we will advise you on whether we will attend or redirect you to your supplier/Gas Safe registered engineer.

If you have turned off your gas supply, please do not try to turn your gas supply back on again. Please contact us on 0800 389 8000, when you are ready to have your supply restored, as this will have to be done by an appropriate qualified person.

If water has got into your gas pipes within your home you will need to contact a Gas Safe registered engineer to clear the system. Call 0800 408 5500 for a list of local Gas Safe registered engineers.

What to do if you are told to evacuate your home due to a flood risk

If you have been advised to evacuate your property by an authorised agency, then please turn off your gas at the emergency control handle. This is normally located next to your meter.

Please do not attempt to do this if your meter is under water or in a cellar.

We do recommend that you ensure your gas appliances are switched off before evacuating your property.
