Most EPC analysis is a snapshot. A consultant pulls the certificates, builds a spreadsheet, writes a memo. Six months later the spreadsheet is out of date. The reassessments aren't reflected. The completed retrofits aren't logged. The new acquisitions aren't in the picture. By the time the next board meeting comes round, the analysis is rebuilt from scratch — at full cost.

Surveys get commissioned on assets that should have been excluded by an exemption test. Capex is committed against generic benchmarks rather than real cost data. Stale certificates from 2012 get retrofitted when a £200 reassessment would have done the job.

The gap is structural. There's no system that holds the current state of a portfolio's EPC and retrofit picture. There's analysis, and then there are folders of PDFs.

UpGreen closes that gap.

A virtual estate — a live model of every asset in your portfolio, with current EPC band, expiry date, MEES position, retrofit Capex, exemption status, and valuation impact attached to each one. Populated within 48 hours of an address list arriving. Kept current from then on.

Specifically, for each asset, you see:

• Current EPC band and expiry date

• Position against the proposed 2027 EPC C threshold and the 2030 threshold

• MEES exemption likelihood under the seven-year payback test and other exemptions

• Whether the certificate is stale and likely to meet C under reassessment

• Costed intervention options, prioritised by cost-to-band and value impact

• Capex within 5–10% of QS quotes

• Valuation impact and brown discount exposure by archetype and location

• Audit trail of every change to the asset record

Filterable across the portfolio. Exportable for boards, lenders, and committees. No site visits required to populate it.

Exemptions reduce active Capex liability. On portfolios analysed via UpGreen, the seven-year payback test alone has cut active retrofit spend by more than 70%. A 67-unit mixed-use commercial portfolio came back as 51 likely exempt and 16 needing capex. That's not analysis you do by eye.

Stale certificates are a cheaper compliance path than retrofit. EPCs from 2012–2014 used different methodologies. Many properties currently rated D or below would already meet C under reassessment. A £200 reassessment is a fraction of a £20,000 retrofit. UpGreen flags every candidate.

Going to B costs roughly 11x what going to compliance does, for an 8% valuation uplift. Across a 31-hotel hospitality portfolio: £60k to full compliance, £1.5m to take the rest to B. Whether the trade-off is worth it depends on the asset and the hold period — UpGreen surfaces it explicitly so the decision gets made on numbers rather than blanket targets.

Tight clusters of high-uplift assets make Capex sequencing obvious. On an 83-unit commercial fund, three G-rated assets sat within £5k of each other on cost-to-B, with valuation uplifts of 63–70%. Once that cluster is visible, the sequencing decides itself.

Public data refresh. When new EPCs are lodged on the MHCLG Open EPC Register against assets in your portfolio, UpGreen picks them up automatically. Reassessment outcomes flow through without you uploading anything.

Document upload. Survey reports, retrofit completion certificates, MEES exemption filings and asset management plans can be uploaded against individual assets. The platform reads them and updates the relevant figures.

Portfolio change. Acquisitions and disposals are added or removed as they happen. The virtual estate reflects the current portfolio, not the one that existed when the first analysis was run.

Audit trail. Every change is logged with date and source. You can see what the portfolio looked like at any past point — useful for lender reporting, board updates, and regulatory submissions.

The result: one place that always reflects where your portfolio is, not where it was.

Compliance planning. Triage the portfolio against the proposed 2027 and 2030 thresholds. Sequence Capex against deadlines. Update the picture as decisions land.

Transaction due diligence. Before acquisition, model EPC exposure across the target portfolio to inform pricing or covenant negotiation. After acquisition, fold the assets into the existing virtual estate.

Exemption applications. Identify candidate assets and pull the supporting data needed to file. Track filings as they progress.

Lender engagement. Show finance partners a costed pathway to compliance and ongoing evidence of progress, rather than a problem statement that ages out.

Board and committee reporting. Export current-state portfolio views without rebuilding the analysis each quarter.

Grant funding. For social and affordable housing portfolios, identify ECO4 and SHDF eligibility and prioritise stock investment around tenant cycles. Reapply as new tranches open.

UpGreen does not deliver EPC certificates. It does not produce SAP or SBEM calculations. It does not deliver PAS 2035 Level 5 retrofit assessments. It is not a digital twin and does not model individual-building physics at high fidelity.

UpGreen sits upstream of those services. It tells you which assets to point them at, and it holds the picture they update.
