About the role
Domestic Electrician — Greater Birmingham. Self-employed profit-share role, not a wage. You keep 25% of every job KJ Electricians routes to you. We handle customer enquiry, pricing and Part P notification through the KJ scheme — you turn up to a priced job with the scope confirmed. You'll be sent to consumer unit upgrades (RCBO CUs), additional circuits, EICRs, socket and light additions, fault-finding, smoke and CO alarm installs, EV-charger enabling work, and minor rewires. Some jobs are 1–2 hour call-outs; others are 1–3 day CU changes or partial rewires. Jobs are dispatched via the KJ portal with the fault description, address, access and price confirmed. Notifiable work is filed by the KJ Part P scheme — you don't need your own scheme membership. Tickets range from around £120 for a socket add up to £1,800+ for a CU + rewire. On a 25% share the calculator above shows what a booked week clears. Suits an experienced domestic sparks with own van and tools. Not for someone without 18th Edition or without commercial installation experience if they want commercial work (that's a separate pipeline).

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.
