IGT vs. National Grid – what’s the difference?

National Grid (or Scotia Gas Networks in Scotland) operate the majority of the UK pipelines. In recent times, though, this market has become more competitive through the emergence of IGTs, or Independent Gas Transporters. An Independent Gas Transporter is a network for gas that is not part of the normal national grid infrastructure. In other words, if you are on an IGT network, then the pipes that supply your gas are not operated by National Grid but by another provider. Scotland is one of the primary regions to adopt their use.

How do I know if I am on an IGT network?

There is a very easy way to establish if you are on an IGT network as your Meter Point Reference Number on you bill will begin 74, 75, 76 or 77. All other Meter Point Reference Number ranges belong to National Grid.

It is possible the letters IGT will appear on you bill also but most suppliers no longer do this.

How does it affect my gas supply?

It doesn’t affect your physical supply in any way as IGT is just the method the gas gets from the source to you. Its like driving the M6 motorway and opting to use the Toll Road, different route but still the same destination.

In the past, your choice of supplier would have been affected as many suppliers would not have taken you on if you were supplied through IGT pipes. This should change with the introduction of Project Nexus in June 2017.

Unfortunately, though, IGT meters do come with a higher standing charge than National Grid supplied meters. In some cases, the supplier will absorb the cost and it has no impact on you. Other suppliers will pass this extra cost on to the end user. If you are on an IGT network it is therefore important to compare a range of suppliers and ensure that every offer you receive contains information on the added extras that may come with an IGT supply.
