Can a garage keep a customer's car until the bill is paid?

A customer picks their car up, the work is done, and the payment does not arrive. Everyone who has run a workshop for more than a year has had it happen, and the reaction is almost always the same: I should have kept the keys.

You probably could have. The right is real, it is old, and most garage owners know it exists without knowing its edges. Those edges are where it goes wrong, because one of them destroys the right instantly and the other gets workshops into genuine legal trouble.

This is general information and not legal advice. If there is real money involved, spend an hour with a solicitor.

The right is called an artisan's lien

The principle is straightforward and it goes back centuries. If you have done work on someone's property, with their agreement, and that work has improved it, you can keep hold of it until you are paid for that work.

In a workshop that means: they asked you to fit a clutch, you fitted the clutch, the car is worth more with a working clutch than it was without one, and the bill is unpaid. You can keep the car.

Three conditions have to hold.

The work was authorised. They asked for it, or they agreed to it when you rang about the extra findings. Work you decided to do on your own initiative does not create a lien, and it is one of several reasons to get approval recorded rather than remembered.

The work improved the vehicle. Repairing, servicing, fitting parts, diagnosing and fixing. This is the usual case and it is rarely the problem. Pure storage does not improve anything, so storage alone does not create this right.

You still have the vehicle. Which brings us to the part everyone gets wrong.

The mistake that ends it instantly

The lien is possessory. It exists only while you hold the car.

Hand the keys over on a promise to pay on Friday and the right is gone. Not suspended, not weakened. Gone, for that job, permanently. You cannot go and collect the car afterwards, and if you take it back without agreement you are the one in the wrong.

This is the single most common way workshops lose it, and it happens for a good reason: the customer is standing in front of you being reasonable, they have always paid before, and holding their car feels aggressive. Then Friday comes and goes.

The decision has to be made at the counter, before the keys move, because there is no second chance at it.

It covers this job, not the last three

The lien secures the debt for the work you have just done on that vehicle. It is not a general right to hold any of their property against any money they owe you.

So if a customer owes you £400 from a job in March and brings the same car in for an MOT in September, you cannot hold the car over the March invoice. The MOT has not been paid for either, and you can hold it for that, but the £400 is a separate debt and a separate problem.

The same applies across vehicles. A fleet customer with six vans does not let you hold van five against unpaid work on van two.

You can keep it. You almost certainly cannot sell it.

This is where workshops get into real trouble, and it is worth being blunt about.

The lien gives you the right to retain the vehicle. It does not give you the right to sell it. Selling a car you are holding, on the basis that they owe you money and will not pay, is not a remedy available to you at common law, and doing it exposes you to a claim worth far more than the bill.

There is a proper route. The Torts (Interference with Goods) Act 1977 sets out a notice procedure for uncollected goods: you serve written notice on the owner, you wait the period the Act requires, and if you do eventually sell, you account to them for anything above what you were owed. It is a process with steps and dates, and it is not something to improvise from memory when a car has been sat on your forecourt for four months.

If you are at that point, take advice. The cost of getting it right is small next to the cost of getting it wrong.

Storage charges only work if you agreed them first

A workshop holding a car for six weeks is losing a space, and the instinct is to charge for it. You can, but only if storage was part of the deal before the dispute started: on your terms, on the job sheet, on something the customer accepted.

You cannot introduce a £20 a day storage charge on week three because the car is annoying you. That is a new term added unilaterally to a contract already underway, and it will not survive being challenged.

If you want that lever, put it in your terms now, while nobody is arguing.

What I would actually do

Holding a car works. It is also the nuclear option, it hurts a relationship that might otherwise have recovered, and it ties up a bay.

Before the work: get authorisation recorded, including the approval for extra findings, with a figure attached. Most disputes are not really about money, they are about a number the customer says they never agreed to. Photos and a written approval end that argument before it starts.

At the counter: decide before the keys move. If the amount is big enough that you would genuinely chase it, do not release the car on a promise. If it is small enough that you would let it go, release the car and stop pretending you have leverage you have chosen not to use.

After it has gone wrong: the lien is no longer available, so you are in normal debt recovery. A letter before action, then the small claims track, which for most workshop invoices is the proportionate route and cheaper than people expect.

And the honest one: the customers who do this are usually not new. There is nearly always a pattern of slow payment before the one that never arrives. Knowing who owes you what, on the day, is worth more than any legal right, because it lets you decide on the next job rather than after it.

Scotland is different

Scots law has its own doctrine of retention with its own rules. It arrives at a broadly similar place, but it is a separate legal tradition and the detail differs. If you are north of the border, do not rely on English common-law guidance, including this.
