Common queries

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 enquiries@recmanager.co.uk

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.

Some organisations require network and security changes by their own IT departments before they can access the portal.
