  • Simple spreadsheet or job app for records
  • Public liability insurance certificate

How to Start

  1. Book a one-day course within 30 miles of your postcode so travel stays cheap.
  2. Buy a used tester only after confirming the calibration sticker date.
  3. Register as self-employed with HMRC online – takes ten minutes.
  4. Arrange £1m public liability cover before quoting any jobs.
  5. Print simple A5 cards and drop them at letting agents in your area.
  6. Contact local HMOs and small offices by phone, not email, for the first three bookings.
  7. Keep every test record for at least three years as required by the Electricity at Work Regulations.

Earnings & Scaling

One tester working three days a week can clear £800–£1,200 a month once regular clients are in place. Growth comes from adding fire-safety checks or taking on another tester part-time rather than chasing volume alone. Firms like PAT Testing Expert show how B2B compliance work builds steady routes.

FAQ

Do I need to be registered with any official body?

No official register exists, but you must follow the Electricity at Work Regulations 1989 and hold valid insurance.

How much should I charge per item?

Most micro operators charge £1–£1.50 per appliance or a flat £70–£90 per hour on site, whichever feels fair for the postcode.

Where do new testers find their first clients?

Start with letting agents and HMO landlords in your immediate area; they need annual tests and pay on repeat.
