Startup costs are typically around £3,000 to £15,000, depending on your tools, van and any qualifications you still need. These are estimates, so get quotes for equipment, vehicle and insurance before you commit.

Monthly revenue is typically around £2,500 to £10,000, depending on how many installs you complete and their size. These are estimates, not guarantees. Work is busiest in warmer months, so plan cash flow for quieter spells.

Check that handling refrigerants needs a recognised certificate and whether F-Gas registration applies to your business. Check whether electrical connections need a competent person scheme or electrician sign-off under Building Regulations, and arrange public liability insurance.
