About the role
Mobility Installer — Coventry and West Midlands. Self-employed profit-share role, not a wage. You keep 25% of every install KJ Mobility routes to you. We handle the customer assessment, product spec and pricing (much of it through OT referrals and local authority grants); you turn up to a priced install with the product on site. You'll be sent to straight-rail and curved-rail stairlift installs, grab-rail and half-step installs, wheelchair ramps, wet-room and level-access shower adaptations (coordinating with KJ plumber/tiler), ceiling hoists and through-floor lift assist visits. Typical install is 2–6 hours; wet-room adaptations run 2–4 days across trades. Jobs are dispatched via the KJ portal with the OT/customer notes, product spec, delivery confirmation and any safeguarding notes flagged. Tickets vary widely (£350 for grab rails up to £5,000+ for a curved stairlift). Suits an experienced mobility installer, or a competent joiner/electrician cross-trained on stairlifts, with the empathy to work in vulnerable adults' homes. Enhanced DBS required.

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.
