Procurement · validation · intelligence

Cut your unit rate. Then cut the units.

Most business energy savings live in two places: a better contract, and the bill validation nobody runs against it. We do both — plus the half-hourly intelligence and demand-response revenue that's been sitting in your meter all along.

No-saving / no-fee on validation. Procurement fee is paid by the supplier — never bolted onto your unit rate.

How we recover money

Every invoice. Every line. Every site.

Suppliers make billing errors at a rate of about 1 in every 8 invoices. Most are small. A handful are catastrophic. We catch them all — and recover the cash.

  • Daily HH ingest
    Direct from your DC/DA. We don't wait for your supplier to send a PDF.
  • Tariff-by-tariff reconciliation
    Day, night, EBRS, capacity, KVA, CCL, FIT, RO — checked line by line.
  • Recovery handled end-to-end
    We raise the dispute, supply the evidence, and chase the credit note.
  • No-win-no-fee
    You only pay a share of recovered money — never a retainer for nothing found.

HH intelligence platform

Daily data. Daily alerts. Decisions in hours, not weeks.

We ingest your half-hourly data direct from your DC/DA every morning at 09:00. By 09:15, you have anomaly alerts, league tables across sites, and a forecast vs. actual on every tariff component.

  • Anomaly alerts
    Spot a chiller stuck on, a meter mis-config, or a forgotten HVAC schedule — same day.
  • Cross-site league tables
    Identical sites benchmarked against each other. Outliers get investigated, not averaged.
  • Forecast vs actual
    Daily and monthly variance against your contract, your budget, and prior year.

Sub-metered tenant recharge

Recharge your tenants — automatically, accurately, in their currency.

For multi-tenant sites, our MID-approved sub-meter network feeds usage and pricing directly into a recharge engine. Tenants see their own bill, you see consolidated revenue, and reconciliation happens monthly without a finance team touching a spreadsheet.

  • MID-approved meters
    Legally billable to tenants under the Measuring Instruments Directive.
  • Per-tenant tariff design
    Different tenants on different blends — flat, time-of-use, or pass-through.
  • Auto invoicing & GoCardless
    Monthly invoice generation, Direct Debit collection, automated chasing.
  • Tenant self-service portal
    Real-time usage, downloadable invoices, usage trend graphs.

Beyond electricity

We also handle the bills nobody talks about.

Water and waste are the two utilities most likely to be overcharged — partly because they're less actively managed, partly because the markets are messier. We treat them with the same line-by-line scrutiny.

WATER

Wholesale water market — switching, validation, leak detection.

  • Switch retailer for a fixed wholesale margin discount
  • Validate every invoice line — supply, sewerage, surface drainage
  • Reclaim historic surface-drainage overcharges (often £k per site)
  • Daily-read AMR for leak detection on suitable meters
WASTE

Audit-grade waste contracts and ESG reporting.

  • Re-tender across 14+ national and regional waste carriers
  • Lift segregation and recycling rates with on-site audits
  • Audit-quality duty-of-care and waste transfer documentation
  • Waste data feeds straight into your SECR / CDP report
