What it is
A small workshop that takes in compressors for bench repair, pump rebuilds, motor and tank work, and full overhauls, and may also sell refurbished units and spare parts.
Your first three steps
- Look at small industrial units or shared workshop space nearby and compare rent, access and lifting needs
- Set up supplier accounts for parts and test equipment such as pressure gauges and a safe test area
- Contact local trade customers and tool hire shops to offer collection, repair and return
Who pays
Workshops, trade customers, farms, hobbyists and small manufacturers who can drop off or send in equipment, and sometimes other repairers who need bench work done.
How it makes money
Labour charged per job or hour, parts sold at a margin, and resale of reconditioned compressors.
Skills that help
- Mechanical and electrical fault finding
- Rebuilding pumps and motors
- Pricing jobs and quoting
- Stock and parts management
Watch out for
- Public liability and tools or stock insurance, plus employer's liability if you hire anyone
- Pressure equipment safety rules; check what applies to testing and returning repaired compressors
- Business rates and planning use class for the unit; check with your council before signing a lease
- Disposal of oil, old tanks and scrap metal in line with waste rules
- Quiet periods can make rent a pressure, so aim for a steady base of service contracts
