Current public position
DESNZ has not announced Phase 5. Phase 4 outcomes have been published; delivery runs to 31 March 2028. The Spending Review and Autumn Statement are the primary signal points for further phases [HMT].
Signals to watch
- Salix newsletter and PSDS portal updates [Salix].
- DESNZ PSDS collection page [DESNZ].
- HM Treasury Spending Review and Autumn Statement.
- Net Zero hub network communications.
What to do in the watch interval
Pre-bid preparation reduces risk if Phase 5 mirrors Phase 3c's 90-minute close. Where projects cannot wait, pivot to the live alternatives: DfE R&R, CIF, GB Energy solar.
