What it is

Installing ready-made garage kits (timber, sectional concrete or steel) on a base, including assembly, roofing, doors and finishing.

Your first three steps

  1. Contact local garage and outbuilding suppliers to ask about subcontract installation work
  2. Price up a typical single garage install, covering labour, base prep, waste removal and your tools
  3. Get public liability insurance and photograph your first jobs for a simple portfolio
Who pays

Homeowners who bought a kit, garage and outbuilding suppliers who need fitters, and small landlords.

How it makes money

Fixed price per installation, quoted from the kit size and base. Regular subcontract work from suppliers can fill your diary.

Skills that help

  • Concrete bases and groundwork may need a subcontractor if you don't do them yourself
  • Heavy lifting and working at height, so plan safe working methods and help on site
  • Being clear in quotes about who is responsible for the base and for any permissions
