Estimates for a small start in the UK, not guarantees.

What it is

You audit how a small business uses energy, check its supply contracts, and recommend changes such as lighting, heating controls, equipment use or switching supplier. You then present a prioritised action list.

Your first three steps

  1. Build knowledge through a commercial energy or energy management course and learn how business energy contracts work
  2. Prepare a sample audit report using a friendly local business or your own past workplace as a case study
  3. Approach local business groups, landlords and accountants who could refer clients, and offer a low-cost first audit
Who pays

Shops, cafes, offices, workshops, care homes and landlords who want lower running costs.

How it makes money

A fixed fee per audit and report, a day rate for larger sites, or monthly retainers for ongoing monitoring and contract reviews.
