Energy · Settlement reform & market change
7 May 2027 is fixed. Is your operation?
Every electricity supplier must finish moving its meters to half-hourly settlement by 7 May 2027 or risk being barred from taking on new customers. Elexon’s own audit found suppliers relying on manual workarounds at scale. Systems migrate. Operations need people who can work the new way.

What your programme needs
Four things that decide whether it lands
Business readiness, not just technical readiness
The systems can be ready while the teams running them aren’t.
We provideReadiness assessment across billing, settlement and customer operations, with the gaps named.
Manual workarounds removed
Hypercare that never ends becomes the operating model.
We provideProcess training and job aids that move teams off workarounds and onto the new process.
Processes that work first time
Weak change-of-supplier and agent controls create costly exceptions.
We provideRole-based training on the processes the audit flagged, built from your own procedures.
Teams that follow the change
Staff who don’t see the reason will default to the old way.
We provideA resistance diagnostic and communication plan that gets teams behind the change.
