You may see one of our survey vehicles driving along roads in your area. We use these vehicles to check the condition of our gas network and identify anything that may need further investigation. This helps us keep your gas supply safe and reliable.
What the vehicles do
Our survey vehicles use specialist sensing, mapping and analysis technology to collect information from public roads. The vehicles are equipped with highly sensitive sensors that detect and measure methane emissions in the air as they travel through an area. This information helps us assess the condition of our gas network and identify locations that may require further investigation.
They travel at normal road speeds, so the surveys are quick, non-intrusive and cause minimal disruption.
If a survey identifies something that needs a closer look, you may later see some of our engineers carrying out further checks.

Why you may see the vehicle more than once
We usually survey each street several times to make sure the information we collect is accurate. We then combine and analyse the results to build a clearer picture of the gas network’s condition.
This helps us decide where maintenance or further investigation may be needed and where to invest in the network.
Your privacy
Our survey vehicles do not have cameras, so do not take photos or videos. They also do not collect any personal information. They are only designed to collect information about our gas network.
By using this technology, we can better understand the condition of our network, keep your gas supply safe and reliable, and reduce disruption in your community.
