Coronavirus (COVID-19) Customer Update

The latest update as we continue to support our customers through the ongoing coronavirus pandemic.

Published on 30 Jul 2021

Dear Customers,

I’d like to share our latest update as we continue to support you through the ongoing challenges and impacts of the coronavirus (COVID-19) pandemic.

Since our last update we have seen further relaxations of Coronavirus restrictions in each of the Home Nations, and there are now very few businesses that must remain closed.  Any site which could be open but has chosen not to (or is unable to open for other reasons such as lack of staff) should not be using the temporary facilities introduced by Urgent Modifications 0722 and 0723.

Here at Xoserve and Correla we have begun to re-open our shared offices in Solihull, initially with a very restricted capacity and social distancing measures in place.  We are not yet able to welcome external visitors to our offices and our default is still for remote working and remote meetings.  We will update our customers when that position changes.

We’ve launched two new interactive versions of our charts showing Unidentified Gas (UIG) data. The charts are accessed directly from the Xoserve website and allow users to customise the date range of the displayed data, as well as reading off the actual values by hovering over a particular day. The charts are:

1. UIG Percentage by Gas Day – shows daily national UIG percentage levels for the first (D+1) and last (D+5) run of allocation (updated weekly).

2. UIG as a Percentage of Total Throughput – shows monthly UIG as a percentage of total throughput at allocation and after reconciliations processed to date (updated monthly).

Both charts are available via the ‘UIG Interactive Data’ area of the Unidentified Gas (UIG) or from the Xoserve homepage, click Services and using the Issue Management dropdown, select Unidentified Gas (UIG).  Graph 1 will be updated around the middle of each week, and Graph 2 will be updated once a month, a few days after the Amendment Invoice is issued.

Because some restrictions continue in all the Home Nations, we plan to issue a further update on Tuesday 31st August.

If you have any queries about this update, please email We’ll respond to every email we receive within 24 hours.

Kind regards,

Andrew Szabo | Chief Customer Officer
