PAS 2035 requires independent M&V. You cannot self-certify performance. Tricity Labs provides continuous, evidence-grade measurement before, during, and after every retrofit — automatically, from existing smart meters.
PAS 2035 is explicit: Building Performance Evaluation must be conducted by a party independent from the retrofit delivery chain. The organisation measuring performance cannot have a financial interest in the results. That rules out self-certification and rules out M&V from any platform owned by a delivery body or contractor group.
No compliant M&V evidence for funder claims. No post-retrofit performance verification for your guarantees. No independent baseline to demonstrate what your installation actually achieved. Manual surveys at every property — expensive, one-off, not continuous.
A continuous, independent evidence layer built on existing smart-meter data — pre-retrofit baseline, monitoring during delivery, and post-retrofit performance delta. No site visits after initial connection. Evidence accumulates automatically, ready for funder submission and inspection.
Half-hourly smart-meter data corrected for local weather conditions establishes the consumption baseline for each property before any work begins. The benchmark every post-retrofit measurement is compared against.
The audit runs throughout the retrofit programme — catching anomalies in real time, flagging underperformance against expected profile, and building an unbroken evidence record from day one to completion.
Performance delta between pre and post-retrofit periods, weather-corrected and EPC-referenced — the independent evidence your funder needs, and the data your guarantee obligations depend on.
⚡ No additional site visits required after the initial smart-meter connection. Evidence is generated automatically and continuously from data the property is already producing.
Not every property in a retrofit programme needs a full sensor suite. Tricity Labs screens your entire cohort using existing smart-meter data first — then recommends targeted sensor deployment only for the properties that need it.
Every connected property screened using existing SMETS2 data. Pre/post consumption baselines, weather-corrected performance comparison, anomaly flags for heating underperformance or unexpected consumption patterns. Covers your whole cohort at low cost.
Suitable for full portfolio M&V, funder claim substantiation, and Warm Homes SHF evidence.
Properties flagged by Tier 1 as anomalous receive a Zigbee sensor gateway — adding temperature, humidity, and occupancy data. Damp and mould risk indicators, heat-loss anomaly detection, and heating system underperformance all become visible.
Targeted deployment only on properties that need it — a fraction of the cost of full hardware rollout across the cohort.
Evidence-grade M&V from existing smart meters costs a fraction of traditional survey-based BPE — with the significant advantage of being continuous, not a one-off snapshot.
Tricity Labs has no retrofit delivery arm. No supply relationship. No financial interest in the results of the evidence it produces. The audit is structurally independent under BS 40101 — defensible at funder audit, at RSH inspection, and in any dispute over retrofit performance.
✅ Most platforms in this space cannot say the same. Structural independence is not a policy position — it is a design decision.
Continuous M&V evidence for ECO4, Warm Homes SHF, and devolved-administration fund claims — generated automatically, ready for submission.
Continuous post-retrofit monitoring flags underperformance against design profile early — giving you time to act before a guarantee claim becomes a dispute.
