What to contact us about

What helps us reply

  1. What system you want to measure, and roughly how large it is
  2. Which meter points you can reach today (M1 to M4)
  3. What you need the result for: internal decisions, a buyer, a report or a regulator

What happens next

  1. We reply by email, and arrange a call if one helps.
  2. For an assessment, advisory or license, we send a written scope and terms before anything is agreed.

Questions

Can you tell us whether our figures comply with EU rules?

We can measure and explain figures against the JL-26 method and show how they relate to EU indicators. Whether you comply is a legal question; see the crosswalk and take legal advice.
