The table shows the flows of gas out of storage and to and from Europe. This covers the period for which data from national grid (the system operator) were available at the time of searching.
During the period the UK was a net importer of gas from Europe on each day, although there was some cross-trading of gas (importing from the Netherlands while exporting to Belgium) on some days.
The relationship between flows patterns can be complex and reflects underlying supply and demand conditions (and thereby prices) at different times and different markets. Contractual and other factors may also play a role. Attempting to map and compare particular supplies of gas into the market to particular flows out of the market would be misleading; what is important is the aggregate supply and demand position.
During the period the UK was well supplied with gas.
