This is usually framed as a loyalty question and it is not one. The two do different work well, and which suits a car depends on its age, its warranty status and what you are asking for — not on a general view about dealers.
What follows is the honest split, including the cases where the dealer is the right answer and this register is not much use to you.
What a main dealer is genuinely better at
Warranty and goodwill work, because it is their process. A car inside its warranty, or close enough that a goodwill contribution is plausible, is usually simpler to take to the network — not because an independent cannot do the job, but because the claim and the repair happen in the same place.
Recalls and campaigns, which are the manufacturer’s to perform. Software and module updates released to the network, which reach independents late or not at all. And the first years of a genuinely new model, where the parts, the training and the fault history exist in one building and nowhere else.
What an independent is genuinely better at
Continuity. A dealer allocates whoever is free; a specialist tends to be a small enough business that the same person sees your car each time and remembers what it did last year. On a low-volume car that is worth more than it sounds.
Cost, but for a specific reason rather than as a slogan. Labour rates differ, and so does what gets replaced: a specialist who sees the same failure repeatedly will often repair a component the network only supplies as an assembly.
And willingness to talk about the car as a whole rather than as a booked job — what is coming, what can wait, what is not worth doing. That conversation is the thing owners describe missing when they leave a good independent.
The questions that actually decide it
General answers stop being useful here, because the split turns on facts about one car. These are the ones worth settling before booking either.
- Is it in warranty, and is the work plausibly a warranty or goodwill matter?
- Does the job need a software or module update that only the network is issued?
- Can the workshop write to the digital service history, or will the record be its own?
- Is there an outstanding recall — which is the manufacturer’s to do, free, wherever else the car is serviced?
- For a sale in the next year or two, does the buyer you have in mind care where the stamps came from?
What the register can and cannot tell you
It can tell you which independents exist, what each says it does, and which of them carry a company number you can look up yourself. That is a real answer to “who is there”, and it is compiled rather than applied for, so a good workshop is not missing because it never filled in a form.
It cannot yet tell you that any of them is good. Nothing on this register has been inspected, every page says so, and a badge here means somebody checked only once that sentence stops being true. Until then this is a map, not a recommendation — and the questions above are how you close the gap yourself.
Information, not advice about any individual car. Guides are written by the register; where one is reviewed by a verified specialist, that is the same specialist you can book through this site.
