What you get

  • Review of your meter plans and boundaries before you measure
  • Review of your ledgers, ratios and reports before you publish
  • Help applying the method to new hardware, task sets or facilities
  • Briefings on regulatory changes that affect your figures, such as the EU rating scheme
  • A named contact and agreed response times

Who it is for

Teams that measure regularly and want expert review without commissioning a separate assessment each time.

How it works

  1. Send an application describing your systems and goals.
  2. We agree the scope, contacts and response times in writing.
  3. Work with us month by month; stop when it no longer serves you.

Price and limit

  • $5,000 a month.
  • At most 300 a year. The limit reflects what we can deliver well; we do not run countdowns.
  • Prices rise 10% each year. A price you have paid stays fixed for the period you paid for; the increase applies from your next purchase or renewal, and we tell you before it does.

Billed monthly under a written agreement. It continues each month until you cancel; the agreement states the notice period, and we tell you before any price change.

What it is not

JL-26, the Joule Ledger, is a proprietary measurement method published by AAERL. It is not a consensus standard and has not been adopted by any standards body or regulator. An audit grade (Declared, Witnessed or Replicated) says who checked a result and how. It is not a certification, an accreditation or a regulatory approval.

Questions

Does advisory include assessments?

No. Witnessed assessments are separate, so the grade stays independent of the advice.
