We’ve seen increasingly wild, wet and unpredictable weather in recent years, so if your home’s in an area that is deemed at risk from flooding, it’s useful to know how to avoid damage to your gas appliances should such an emergency arise.

Before a flood

Get in touch with a Gas Safe registered engineer to request an assessment. They’ll let you know how best to protect your appliances and pipework from water damage.

During a flood

If you’re advised to evacuate your property, then you’ll need to switch off the gas supply at the Emergency Control Valve, so long as it’s safe to do so. This is usually found next to the gas meter; if you can’t find it, contact the Gas Emergency Service Provider for your region.

You’ll also need to contact a competent electrical person to make sure your property’s electrical supply and all electrical appliances are safely disconnected.

If your property is supplied with liquefied petroleum gas (LPG), it’s important to note that flood waters can cause LPG bulk storage vessels and gas cylinders to move or detach from installation pipework. Before any work is carried out, you’ll need to get in touch with your LPG supplier for assistance.

After a flood

If your house has flooded, we understand that this can be an overwhelming and stressful experience. Here are the steps you need to take to stay safe and preserve, where possible, the integrity of your appliances until a registered engineer can assess any damage:

  1. Contact your gas supplier so they can advise you of the general situation in the area.
  2. Get in touch with a Gas Safe registered engineer before turning on the gas supply. They’ll make sure the installation pipework isn’t filled with water. If it is, this must be removed from the supply before the gas appliances can be re-checked, confirmed as safe, and used as normal.
  3. If you’re using pumps and generators to clear flood waters, be sure to follow the manufacturer’s instructions and make sure there’s enough ventilation to prevent potential carbon monoxide exposure.

When a Gas Safe registered engineer visits your property, remember to check their Gas Safe ID card too.
