About the role
Bathroom Plumber — Greater Birmingham. This is a self-employed profit-share role, not a wage. You keep 25% of every job value KJ Bathrooms routes to you — no day rate, no chasing customers, no unpaid quotes. We generate the demand, price the job with the customer, and dispatch it to you priced and confirmed. You'll be sent to a mix of full and partial bathroom refurbs, suite swaps, electric and mixer shower installs, waste re-routing, silicone and sealing, tap and cartridge swaps, and leak diagnostics on existing suites. Some jobs are one-day fixes; others are 2–4 day refurbs where you coordinate with a KJ tiler or electrician also dispatched by us. Typical week is 3–5 jobs within roughly 30–40 minutes of your base, dispatched via the KJ portal the night before with live updates on the day. Tickets range from around £180 for a small repair up to £2,500+ on a full refurb, so on a 25% share a solid week comfortably clears what most bathroom fitters earn on PAYE — see the calculator above for realistic ranges tied to job flow. Suits an experienced bathroom fitter / plumber with own tools and van who wants to be handed priced, agreed work instead of quoting and chasing. Not for brand-new apprentices or new-build first-fix only crews — we're refurb and reactive.

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.
