Your first three steps

  1. Look into the training and certification needed to handle refrigerants and do electrical connections, and book a course
  2. Contact local builders, shopfitters and property managers to ask about subcontract work
  3. Get quotes for tools, a vacuum pump and gauges, insurance and a van, then set your installation and maintenance prices
Who pays

Quoted prices for installs, plus annual maintenance contracts and one-off repair or clean visits.

  • Neat, careful installation work
  • Measuring and quoting jobs accurately

Watch out for

  • Building regulations on ventilation and electrical work, which may need a competent person scheme or a sign-off
  • Work can be seasonal, with the busiest period in warmer months
