Becoming a mobile mechanic: choosing the jobs.

The work for your driveway

Some tasks are genuinely better performed at the customer's home than in a garage, and these are the ones to base your business on.

• Diagnostics, where knowledge is key rather than lifting gear.
• Batteries, alternators, starters, and most electrical tasks.
• Brakes on many vehicles, where the work is contained and predictable.
• Servicing, filters, and fluids, provided waste can be managed and removed.
• Pre-purchase inspections, which are much more effective where the car is located.

What they share is predictability in duration, requiring no lifting beyond a jack and axle stands, and are unlikely to turn into jobs that can't be completed the same day.

Jobs to decline, and why:

Becoming a mobile mechanic means judging jobs, because being able to do one is not the same as it being sensible on a driveway.

Any job needing the car in the air for long, where a seized fastener turns two hours into six, or that leaves the vehicle undriveable if it goes wrong belongs in a garage. The risk isn't the difficulty, but that a mobile mechanic who can't finish leaves a customer without a car and no space to move it into.

Weather, light, and the surface matter too. A sloping gravel driveway isn't a place for a car on stands, and being willing to say so is a professional judgement, not a lost job.

Parts are the toughest logistics issue.

A garage orders parts and starts tomorrow. Becoming a mobile mechanic means arriving first and finding out later.

Accurate identification before arrival makes the difference between a completed job and a wasted morning. Taking the registration and confirming the variant, rather than relying on the customer's fault description, ensures you arrive with the right part.

Most operators settle on a two-visit model for uncertain jobs: a charged diagnostic visit that provides an answer, then a return with the correct parts. Customers accept this when explained at booking but resent it when discovered on the day.

Pricing travel and uncertainty

Two costs sit outside the labour and are routinely absorbed.

Travel each way is the obvious one. The less obvious is uncertainty: a mobile job that differs from the one booked has no bay to absorb the overrun, affecting the rest of the day, not just that hour.

A minimum charge, a diagnostic fee credited against the repair, and a stated radius cover most of it. So does quoting a range rather than a figure for anything not yet diagnosed, which is honest and avoids the dreaded conversation.

Waste, weather and the unspoken issues

A driveway lacks a drain, covered bay, and waste collection; all three are your responsibility, not the customer's.

Oil, coolant, filters, and old parts must leave with you and be disposed of correctly, under the same duty of care as a garage. Working in the rain raises health and safety concerns as well as comfort; a customer wanting work done in a downpour should be rescheduled.

Being clear about this at booking distinguishes a professional operation from someone with a toolbox, filtering out jobs that were unlikely to succeed.

What the business truly needs to function

Trade skills are assumed. Transitioning to a mobile mechanic business rather than just a series of jobs relies on less obvious factors.

Insurance covering work on customer vehicles off-site, as a policy for a garage may not apply. A method for taking payment before you leave. A system for records to ensure returning customers are recognised. A booking process that accurately captures vehicle details rather than relying on a phone call and a note.

None of this is thrilling, yet it transforms a series of jobs into a sustainable operation when busy, the point where most sole traders either grow into a business or stall.
