Why this works in Johannesburg
Demand in Johannesburg is strong, and the work is a fair share of repeat work. Setting up is a bit of work, and you could be paid for your first job within a few weeks.
Where the first customers come from
- Google Business Profile
- Electrician referrals
- Holiday-let manager contacts
- WhatsApp Business
- Local Facebook groups
- Gumtree
Before you take on work
- Public liability insurance
- Anything altering fixed wiring is notifiable electrical work for a registered electrician
- Smart locks and cameras carry the same data protection duties as any CCTV
