About the role
EV Charging Installer — Greater London. Self-employed profit-share role, not a wage. You keep 25% of every install KJ Electricians routes to you. We handle the customer enquiry, OZEV eligibility, DNO notification and pricing; you turn up to a fully packaged install. You'll be sent to 7kW home chargers on domestic driveways (single and dual phase), load-management retrofits, tethered and untethered units, occasional 22kW three-phase installs, and workplace charger add-ons on small commercial sites. Typical install is 3–5 hours; more complex three-phase or long cable runs go into a second visit. Jobs are dispatched via the KJ portal with the survey photos, unit spec, cable route, isolator location, DNO reference and price confirmed. Tickets are typically £900–£2,400+ on 7kW work, higher on three-phase. Suits an experienced electrician with 2919-01 (EV) and 18th Edition, own van and calibrated test kit. Not for someone without 18th Edition or without at least 6 months of EV install experience — this is safety-critical work.

Why KJ, not a company job
A plumber does 3–4 jobs a day; a surveyor 2–4; a solicitor a handful of matters. The client pays hundreds — often thousands. You take home a fraction. The company keeps the rest.
