Mobile mechanics: what they can and can't do

A mobile mechanic who comes to your driveway or workplace can be genuinely convenient, but it's worth knowing upfront what they're set up to handle and what still needs a proper garage visit before you book one expecting to cover everything in one go.

Mobile mechanics are generally well suited to jobs that don't require a vehicle lift, a pit, or bulky specialist equipment. That covers a fairly wide range of common work: brake pad and disc replacement, battery testing and replacement, diagnostics using a portable code reader to identify warning-light faults, routine servicing including oil and filter changes, and many suspension component replacements. For jobs like these, a mobile mechanic turning up with a fully equipped van can do everything a garage visit would, without you needing to be without your car or arrange a lift somewhere.

There are, however, clear limits. The most absolute is the MOT test itself — this cannot legally be carried out anywhere other than a DVSA-approved test centre, using the specific testing equipment and facilities that approval requires. A mobile mechanic can do useful pre-MOT work — checking and fixing common failure points like lights, tyres and fluid levels before you book the actual test — but the test itself always has to happen at an approved centre. The other significant limitation is major mechanical work that needs a vehicle properly lifted or supported, most notably substantial gearbox or transmission repairs. Many modern gearboxes need specialist lifting equipment and workshop facilities that simply can't be transported in a van, so if you're looking at a major transmission fault, you should generally expect that to mean a garage visit regardless of how good your local mobile mechanic is.

On cost, mobile mechanics commonly work out cheaper overall, though the comparison depends on exactly what you're including. Hourly labour rates for a mobile mechanic are commonly around £45 per hour, against roughly £60 per hour at a traditional garage — but mobile mechanics typically add a separate callout fee, commonly somewhere in the £45-£85 range, so it's worth checking the total cost of a job rather than just comparing the hourly rate. Once that's factored in, mobile mechanics are commonly cited as running around 15-30% cheaper than an equivalent garage job overall, and the gap tends to widen further if a garage visit would also have meant paying for recovery or losing the use of your car for the day. As a couple of concrete examples often cited: a battery replacement might run to around £95 with a mobile mechanic including parts and fitting, against something closer to £220 once you factor in a garage visit that also needed recovery; brake pad replacement might run around £145 mobile against around £220 at a garage once you account for a day without your car.

Beyond straightforward cost, the convenience factor is often the real deciding point for a lot of people. A mobile mechanic working at your home or workplace means you're not without your car for a day, don't need to arrange a lift or a courtesy car, and don't have the hassle of getting the car to and from a garage if it's not entirely reliable in the first place — genuinely useful if the fault you're calling about is something that makes driving the car any distance feel risky.

As a practical rule of thumb: for diagnostics, batteries, brakes, routine servicing and most electrical or suspension work, a mobile mechanic is well worth getting a quote for alongside a garage, and often works out both cheaper and more convenient. For an MOT test itself, or for major transmission and gearbox work, you should expect to need an approved test centre or a properly equipped garage regardless of who you'd otherwise prefer to use.

Before booking, it's worth applying much the same checks you'd use for any garage. Ask whether the mechanic carries public liability and professional indemnity insurance, since that matters if something goes wrong with the work or damage occurs to your car or property while they're on site. Ask for a written quote covering parts and labour separately, ideally before they arrive rather than agreeing a price on the driveway once they've already started. And check recent reviews specifically for mobile work, since the logistics — turning up on time, working safely on a driveway or in a car park, having the right parts with them on the day — matter in a way that's slightly different from a fixed garage premises. If a job turns out to need equipment or space the mechanic hasn't brought, a reputable one will say so upfront rather than attempting a job that isn't practical outside a proper workshop, and will point you toward a garage that can finish it instead.
