The window between waves is not downtime — it is exactly when evidence collection should start. Associations that begin now will bid with a full year of measured baseline data. Those that wait will be modelling estimates against bids that aren’t.
Wave 3 closed in November 2024. The associations that are already ahead of Wave 4 are not waiting for an announcement — they changed the question they were asking.
The pre-retrofit baseline is the foundation of every compliant Wave 4 bid. You cannot go back and create it after the wave opens. Every month that passes without live smart-meter data is a month of evidence your bid will never have.
Wave 4 bidders with twelve months of measured baseline data will outcompete those with three. The gap is not recoverable. The associations starting now are building an advantage that cannot be bought when the wave opens.
Wave 3 guidance confirmed additional scoring points for applications using smart-meter data to evidence pre- and post-retrofit improvement in the Strategic Partnerships stream. Wave 4 is expected to maintain or strengthen this weighting.
DESNZ requires pre-installation data and quality-assured evidence throughout delivery, with TrustMark lodgement and an ISAE 3000 assurance report. The fund obliges you to prove the project — the tool that proves it is a legitimate ancillary delivery cost.
Cryptotricity’s pilot programme connects up to 1,000 homes from your stock. Within that cohort, live smart-meter data automatically surfaces the 100 properties showing the highest energy consumption, greatest retrofit need, and lowest current performance score.
The result is a prioritised, evidenced shortlist — ready for your Wave 4 submission before the wave announcement, not after it.
🎯 The 100 homes most in need of retrofit action, identified from live data — not desk-based estimates. Your Wave 4 bid starts from a position of evidence, not assumption.
Smart meters in 1,000 connected homes report live consumption data continuously.
The platform ranks every home by energy intensity, EPC trajectory, and retrofit opportunity score.
The 100 highest-priority homes are surfaced with a verified baseline already attached.
Your Wave 4 bid is submitted with measured evidence — not estimates.
The grant funds three distinct evidence deliverables — one before works begin, one during delivery, and one after completion. All generated automatically from your tenants’ smart meters.
Wave 4, like Wave 3, will carry a match-funding requirement — the grant does not pay for everything, and your association co-funds part of the project. We are an ancillary cost within that funded envelope, not a separate pot of free money.
We are also not your grant-eligibility adviser: the final decision on what your bid includes rests with you and your funding lead. The no-cost DESNZ ‘RISE’ facility can confirm eligibility independently.
What we can say with confidence is that measurement and verification is a required, fundable part of every project — and that delivering it is precisely what we do.
Awaab’s Law compliance. Continuous smart-meter monitoring provides damp-and-mould risk detection data that evidences your response timescales — a requirement that sits alongside MEES 2030 and is satisfied by the same infrastructure.
Every month of smart-meter data collected now is a month of baseline evidence that competitors who wait simply cannot recover. The gap compounds with every wave.
The work to be bid-ready starts before the wave opens, not when it does. By the time Wave 4 is announced, the associations already in the pilot programme will have a prioritised, evidenced shortlist of their 100 highest-need homes ready to submit.
Those who start now will bid from measured fact. Those who wait will bid from estimates — against associations that aren’t.
Baseline data collection begins immediately. Wave 4 bid built on a year of measured evidence. Top 100 shortlist ready before the announcement.
No baseline. Estimates only. Your bid competes against associations that have twelve months of verified data already attached.
Wave 4 announcement timeline. DESNZ has not confirmed a Wave 4 opening date. The interval between Wave 3 closing and Wave 4 opening is the most valuable evidence-collection window available. It will not repeat.
The pilot connects up to 1,000 homes from your stock and automatically surfaces the 100 in greatest need of retrofit action — with a verified baseline attached and ready for your Wave 4 submission. No operational budget required to begin.
