From utility bills to reports in three steps
- 1
Enter your bills
Electricity and gas bills: billing period, kWh, meter number (MPAN/MPRN), actual or estimated read. Checked in your browser — nothing is uploaded.
- 2
We check and calculate
Missing months, duplicates, estimated reads and meter mismatches are flagged. kWh × DESNZ 2024 factor ÷ 1,000 = tCO₂e, with every step shown.

Five core tools
Bill ingest
Source files listed with a SHA-256 hash of the extracted record. Missing data is flagged, never filled in.

Deterministic calculation — not external assurance or audit. Sample data for demonstration only.
Audit model
Three lines of defence, from bill to workpaper
Built so a corporate ESG team or external reviewer can follow any number back to the bill it came from. vsmecap prepares data for review; it does not provide assurance.
- 01Raw bill PDF
Original supplier bill kept as the source file. A SHA-256 hash of the extracted record is stored beside it.
- 02Extraction engine
Supplier, meter, period, kWh and reading type extracted. Estimated reads, gaps and duplicates are flagged.
- 03Calculation engine
Deterministic: kWh × versioned DESNZ factor. Same inputs always give the same output and hash.
- 04Reviewer workpaper
Every figure traceable back to its bill, factor and formula — ready for your reviewer or auditor to check.
Who it's for
One record, three audiences
- Supplier rollout dashboard: who has responded, who hasn't
- Respects the value-chain cap — requests stay within VSME for suppliers under 1,000 employees
- Export to your ESG tools via JSON/CSV (ERP connectors planned)
Uploads bills, approves what is shared
Sees only passports shared with them
Views workpapers and hashes, cannot edit
Views shared portfolio figures
Product areas
Four product areas, one evidence foundation
Evidence Intelligence (foundation)
The record everything else is built on: collected once, validated continuously.
- Vault + SHA-256

About us
Why vsmecap exists
The problem
Large customers, lenders and public buyers increasingly send sustainability questionnaires down their supply chains. Most small businesses have no specialist staff and no budget for consultants, so answers end up guessed, copied or left blank — and contracts are put at risk.
Our mission
Make voluntary sustainability data verifiable and accessible to every UK small business.
Carbon figures shouldn't need a science degree or a large advisory invoice — just your own bills, published government factors and arithmetic anyone can re-check.
Operating principles
01
Deterministic over estimated
If a figure isn't backed by a real bill and official UK government conversion factors, it's a guess — and we label it as one.
02
Your data stays yours
Bill figures and meter numbers are processed in your browser. We don't store them.
03
Built for the SME operator
No consulting jargon, no opaque ESG scores. Clear, reproducible workpapers you can hand to a customer or reviewer.
04
Honest about what we are
Data preparation and voluntary reporting readiness — not external assurance, audit, certification or legal advice.

vsmecap started from a simple observation: the businesses being asked for sustainability evidence are the ones least equipped to produce it. The aim is practical tooling that turns everyday utility bills into figures a customer or reviewer can trace back to source — without adding paperwork.
