220+ deterministic checks before AI touches anything
Mass balance, format matching, baseline anomaly detection. Failures land in quarantine for review — never in your return.
EPR compliance for producer groups
Pact validates, classifies and consolidates packaging data across your whole corporate group — every figure traceable to a versioned rule and a source row.

The problem
Modulated EPR fees price every tonne by recyclability. One mis-keyed unit weight, one mis-classified material, one subsidiary's spreadsheet pasted wrong — and the error compounds across millions of rows before anyone sees it. Defra doesn't accept “the spreadsheet was wrong.”
Quantify your exposure
An indicative estimate from the live pEPR disposal fees and the published recyclability-modulation trajectory. Nothing you enter is stored or sent.
Red-rated tonnage carries up to a 2.0× fee by 2028/29. Green and amber stay flat.

The swing between classifying that material right and getting it wrong. Today, can you prove which number you'll file?
Indicative · disposal fees only (excludes PRN) · blended £423/t · ruleset 2025.04.01. Across ~3 entities — each filing its own Defra return, each needing its own audit trail to reconcile into this group figure. Your exact, audit-traceable figure is computed on your own data.
How Pact prevents it
01 · Validate
Mass balance, format matching, baseline anomaly detection. Failures land in quarantine for review — never in your return.
02 · Classify
From CSV, ERP feeds, photos or PDFs — every AI output passes back through the validation layer with its reasoning recorded.
03 · Calculate
Fee rates live in a versioned ruleset synced from GOV.UK guidance. Re-run any period against any ruleset version and get the same answer, every time.
04 · Trace
Click any number in any return and walk back to the rule version, the source row, the classifier reasoning and the validation pass. Permanent and queryable — that's the audit pack.
Built for groups
Native parent/subsidiary tenancy — not a consolidation spreadsheet. Each entity gets its own data, its own Defra CSV, its own audit pack. The group lens rolls every subsidiary into one liability view your board can sign off.
