A GT1 Survey is an essential test if you’ve moved to a new property or business premises where you don’t currently have a meter. The GT1 test, or Gas Transporter 1 test, will give you important information about the gas supply before having a meter attached. Once you know this information, you’ll be able to ascertain whether the infrastructure is currently in place to provide the gas supply you need for your home or business, or whether a new gas connection needs to be made.
If you’re looking for a GT1 survey, we’ve got all the information on how to apply for a test, what the test looks out for and much more.
Here are the steps that we will take you through to get a Gas Transporter 1 (GT1) survey. Don't worry, we’ll stay in touch along the way to make sure it's going smoothly and you’re happy with everything.

If you’ve moved into a domestic or commercial property without a meter, a GT1 test is essential if you intend to increase the volume of gas to your property or have a gas meter fitted. Some of the things that a GT1 test will tell you include:
An engineer will usually need to visit the site in order to carry out the GT1 survey, although they can be done remotely on occasion. The length of time it takes to carry out the test can range from a few days to a few weeks, depending on a number of factors including weather conditions and the availability of engineers.
You can apply for a GT1 survey by downloading the Energy Networks Association (ENA) request form from their website here and click on 'Gas transporter documents’. If a capacity increase is required you can go through your Independent Gas Transporter (GT) or Utility Infrastructure Provider (UIP) for an alteration and increase in load – in some places this will be Cadent.
Before getting started, you’ll be required to fill in a GT1 test request form. This will ask you for the following information:
