Or 17:00 - 18:00, depending on your supplier or which scheme you're taking part in.

BG have been doing them regularly. I also found on their website they add all the credits up & apply them to accounts at the end of the month.

Yesterday NGESO published an updated Market Information Report on the current state the DFS program:
https://www.nationalgrideso.com/document/301346/download

In this report they confirm that the most recent session was the last one to use a Guaranteed Acceptance Price (the £3/kWh figure all previous tests have been ran at) and that all remaining tests will now use the "competitive bidding" structure. The document linked above is quite short for anyone wanting to read in full, but here's a brief extract summarising the pricing changes:

the Guaranteed Acceptance Price will be set to £0/MWh and a volume requirement will be set to engineer price competition between Registered DFS Participants.

[...]

The ESO will be seeking to test a range of competition levels and understand the economics of flexibility against the Balancing Mechanism, existing ancillary services, and other actions.

It seems the remaining tests will be further exploring the short-notice aspect of the scheme with a focus on within-day procurement, and that we should expect to see a range of different prices over the coming sessions

They have also inadvertently indicated the next test session will take place from February, so likely no more for this month. Live events are, of course, unaffected by any of this and will be ran as normal if and when they are needed (although the likelihood of that being necessary is decreasing as we move out of January).
