PSDS Phase 5 — What FE Colleges Should Plan For
PSDS Phase 4 round 3 results announced May 2026; Phase 5 expected autumn 2026. What FE Sustainability Leads should plan for in scoring criteria, bundle requirements, and bid timing.
DESNZ announced PSDS Phase 4 round 3 awards on 12 May 2026 — £148m across 47 public sector bodies, of which £22m went to FE estate across 8 corporations including three land-based colleges. Round 4 expected autumn 2026; Phase 5 forthcoming 2027. Here’s what FE Sustainability Leads should plan for now.
What PSDS Phase 5 will probably look like
Three structural trends from Phase 4 inform Phase 5 planning:
- Tightening scoring threshold. PSDS Phase 4 round 3 awards averaged 0.94 tCO2e per £100 of grant — up from 0.78 in round 1. Pure-PV bids now consistently miss threshold; bundled bids dominate the awards.
- Heat decarbonisation weighting up. Air-source heat pump installs paired with PV scored 22% above PV-only across Phase 4. Phase 5 likely continues this weighting.
- Public-sector net debt scrutiny. Treasury concerns about public sector capital expenditure mean Phase 5 may have tighter project size caps or stronger value-for-money scoring.
For FE corporations: the planning window for a Phase 5 bid starts now. Whether the corporation has banked Phase 4 funding or not, Phase 5 is the next major decarbonisation capital opportunity.
How to position for Phase 5 now
Five actions to take in 2026 to be ready for Phase 5:
1. Baseline scope-1 and scope-2 emissions
The Phase 4 scoring requires auditable baseline carbon data — 12+ months of gas and electricity meter data, modelled against grid carbon intensity. Corporations that go into the bid process without this lose 4-6 weeks to data collection.
2. Identify the heat decarbonisation pairing
PSDS Phase 5 will almost certainly require heat decarbonisation as part of the bundle. The strongest pairings for FE estate:
- Air-source heat pump replacing end-of-life gas boilers in main teaching block
- Heat network connection where the campus sits inside or near a developing local heat network (Birmingham, Leeds, Bristol, Cardiff have active heat network projects)
- Combined heat and PV with battery + smart load shifting for high self-consumption
3. Scope the PV element
Rooftop PV typical 200-600 kW per campus; group corp programmes 1-3 MW. The PV element is the easier component — DNO G99 application, structural survey, MCS-certified install all routine.
4. Prepare corporation board approval
PSDS bids require board-approved capital commitment to the matched-funding element (where applicable) and the long-term operational responsibility for the assets. Board paper drafted with timeline aligned to expected Phase 5 open date.
5. Engage Skills England linkage
T-Level Building Services Engineering, T-Level Construction, T-Level Engineering all map directly to a PV + heat-pump install. Bidding narrative ties the project to skills throughput evidence.
Expected timeline for Phase 5
Based on Phase 3-4 patterns:
- Q4 2026: Phase 5 round announcement and scope confirmation
- Q1 2027: Bid window opens (typically 6-10 weeks)
- Q2 2027: Statutory scoring period (8-12 weeks)
- Q3 2027: Award notifications
- Q4 2027 onwards: Project delivery (typically 18-24 months)
For FE corporations targeting Phase 5: feasibility commissioning in Q3/Q4 2026, bid drafting January-February 2027, submission February-March 2027.
What’s already strong in FE Phase 4 awards
The 8 FE corporations that won Phase 4 round 3 had common features:
- Bundled bids (PV + heat pump + building fabric in most cases)
- Pre-existing AoC Climate Action Plan with detailed scope-2 reduction trajectory
- Multi-site or land-based estate giving strong unit economics
- Industry partnership evidence (MCS installer + DNO + apprenticeship training)
- Specific Skills England framing
Backup plan — what if Phase 5 is delayed
DESNZ could delay or restructure Phase 5. If that happens, FE corporations with their planning done have multiple alternatives:
- Pure Salix Decarbonisation Loan (£600k cap; multiple sequential bids for group corps)
- FE Capital Transformation Fund embedded sustainability
- Welsh Government Energy Service (Welsh colleges)
- PSEEL — Scottish equivalent of Salix
- DfE NI Sustainability and Decarbonisation Capital (NI colleges)
- MCA decarbonisation pots
- T-Level Capital embedded sustainability (forthcoming round 5 — see news)
The planning work isn’t wasted regardless of Phase 5 specifics.
