What it is

A small workshop with a bench, test weights and spares where you repair and calibrate precision, bench and industrial scales. Customers bring or post equipment in, and you return it with a calibration record.

Your first three steps

  1. Build experience or training in scale repair and calibration, and decide which types of scale you will cover
  2. Set up a bench in a spare room, garage or small unit, and buy test weights and diagnostic tools
  3. Contact local scale dealers, labs and businesses to offer repair and calibration, with simple collection or postal options
Who pays

Labs, schools and colleges, pharmacies, jewellers, packing firms, engineering businesses and other scale dealers who want a repair partner.

How it makes money

Fixed or hourly repair charges plus parts, and a fee per calibration. Regular work from dealers and businesses with several scales brings steady income.

Skills that help
  • Electronics fault finding
  • Precise, patient measurement work
  • Record keeping and clear paperwork
Watch out for
  • Calibration certificates carry weight, so check what accreditation customers expect (for example UKAS) and what you can honestly claim
  • Scales used for trade have legal requirements, so check with Trading Standards and the National Measurement Office
  • Working from home may need permission from your landlord, mortgage lender or council, so check before you start
  • Public liability and professional indemnity insurance, plus cover for customers' equipment while it is with you
  • Test weights and measuring equipment need regular checks, which adds ongoing cost
  • Courier damage to precision scales, so agree packing and liability terms
