Experiencing issues accessing either the Xoserve Services Portal or GES?
Are you having issues accessing the Xoserve Services Portal, or once logged in, the GES?

How do I use the GES?
The REC portal contains a range of guidance materials to help you use the GES. These include an Online Portal User Guide, API technical specifications, an FAQs document and a video overview of the online portal and APIs.
You can access this material on the following links:
If you’re having problems logging in, your Master Administration User (MAU) can help. Previously carried out by your Local Security Officer (LSO), your MAU can help you access or log in to GES.
If you don’t know who your MAU is, please contact your REC Code Manager at firstname.lastname@example.org
The address in GES may not appear because there may not be a registerable measurement point, also known as a supply meter point, associated with it or the site.
The ‘Domestic Premises Indicator Market Sector Code’ (also known as the Market Sector Code) will show “True” is the supply meter point is Domestic, or “False” if it’s Non-Domestic on the GES Online Portal’s Switching Data tab.
This data is known as Market Sector Code and has a D (Domestic) or I (Industrial & Commercial) indicator on the Meter Point information tab. This is also within the Supply Point Switching and Supply Point Enquiry APIs.
Your Master Administration User (MAU) can help you deactivate your GES online account.
To report a technical service incident where you’re unable to access GES, or if you’re not receiving a response from the GES APIs, please raise a support request.
The Gas Enquiry Service Online Portal is made available under the Retail Energy Code (REC). Access to the Gas Enquiry Service Online Portal is restricted to those organisations which have qualified for access under the REC (known as REC Service Users).
