Bill validation on every invoice, every billing cycle

Validation is a comparison against the contracted rate, carried out on every invoice, every billing cycle. The consumption side comes from the same data the dashboard runs on: half-hourly electricity, gas and water at meter level, refreshed roughly every 30 minutes after settlement, with non-half-hourly meters covered by AMR and supplier billing data. Because Insights consolidates every site under one login regardless of supplier, the check covers the whole portfolio rather than one supplier's account at a time.

Scale does not change the process. An account can carry 1 to 1,000+ meters, with sub-meters in addition, and up to 6 years of historical data where supplier data flows allow. Every meter is checked on the same cadence, whether the portfolio is a single site or several hundred. Variances are recorded site by site, so a finance team reviewing the month sees which invoices matched the contract and which did not, instead of a portfolio-level total that hides both.

Two things run in parallel. Validation compares the invoice against the contract. Anomaly detection works on the consumption itself, so a problem is visible before it reaches an invoice at all. Peak-demand and DUoS red-band exposure is flagged before the charge hits the bill, which gives a facilities team the chance to act inside the month rather than explain the number afterwards.

Thresholds are configurable per meter and sub-meter, and alerts go out by email, SMS or webhook, as a daily digest or in real time, with escalation routing. Recipients are chosen at onboarding, alongside the portfolio list or latest bills and the data-access letters of authority. Role-based access and unlimited users per account mean the person who needs to see a billing variance and the person who needs to fix a plant fault can both be on the list, with permissions set per site, group or function.

When an overcharge is flagged, Purely's account team raises the credit note with the supplier and chases it to ledger. The customer does nothing. The credit, the date it landed and the reason appear in the monthly reconciliation pack, so the recovery is auditable rather than anecdotal. A flagged variance that nobody pursues is not a saving, it is a line in a report, and the difference between the two is who owns the follow-up.

One published example: a hotel group with 11 properties had a bill validation alert in month 2. The supplier issued a £6,400 credit and corrected the going-forward rate. The correction is the larger half of that result, because an incorrect rate left in place repeats on every invoice until someone challenges it. Validation every billing cycle is what turns a one-off catch into a permanent correction.

Purely Insights is included with every Purely Energy supply contract at no extra cost. There is no per-meter fee, no kit-rental fee, no minimum portfolio size and no hidden uplift on the unit rate. The platform is funded by a disclosed broker margin on supply of 0.3p to 1.0p per kWh depending on volume and term, shown line by line on every quote and renewal. There is never a separate Insights invoice.

Each month you receive one supplier invoice per fuel per meter, plus one free Purely-side reconciliation pack covering every site, every variance, every credit and the running annual position. Renewal-window alerts land at 6, 9 and 12 months before contract end, and the renewal recommendation separates wholesale, non-commodity, supplier margin and Purely margin. The same line-by-line discipline applied to invoices is applied to the next contract.
