How to Keep Garage Customers Updated on Repairs
RAC surveyed 1,050 UK drivers in February 2025. More than a quarter, 27%, said getting a car serviced or repaired is a hassle. For those drivers, the journey to and from the garage bothered more of them (68%) than being without the car (47%) (RAC). Keeping garage customers updated is the part a garage controls.
Most advice on garage customer updates stops at “communicate more”, which is true and useless. A repair has four moments when the customer needs to hear from you: booked in, diagnosed, extra work found, ready to collect. Two of those are courtesies you choose. The other two are closer to obligations.
Here’s the problem in a single illustrative scene, invented rather than observed. A car is in for a service, the technician finds a seized caliper, and the job stops there, with the bay held while nobody can reach the owner.
Key Takeaways
- A repair has four moments when the customer needs to hear from you: booked in, diagnosed, extra work found, ready to collect. Only two of them are optional.
- Extra work is not an update. The Motor Ombudsman states that work increasing the price “should not be carried out without the customer’s authorisation”, even where an estimate was given (The Motor Ombudsman).
- A quote and an estimate are different things. The Motor Ombudsman describes a quote as a fixed price agreed in advance, and an estimate as an approximate indication that may change (The Motor Ombudsman).
- Saying “it’ll be ready by four” is more than a courtesy. Business Companion, the guidance backed by the Chartered Trading Standards Institute, says promises about timescales bind where the consumer relies on them (Business Companion).
- Getting to the garage is part of the job. RAC found that more than a third of drivers who get a vehicle serviced (35%) travel five or more miles, rising to 48% in rural areas (RAC).
- The hardest update to send is the one where nothing has changed, and it’s the one most advice skips.
The four moments a garage customer needs an update
A repair is one long silence broken by two phone calls, and most of the trouble lives inside the silence. Split it into four moments and it gets easier to run.
| Moment | What the customer needs to know | How it goes wrong |
|---|---|---|
| Booked in | What was agreed, and when they’ll next hear | Keys go in a drawer, nothing said about timing |
| Diagnosed | What’s actually wrong, and what that changes | They find out at the counter when they collect |
| Extra work found | What it costs, and that a decision is needed | The work gets done and the invoice explains it |
| Ready | That it’s finished, how to collect, and by when | A call at five to five, or none at all |
Moments one and four are the ones every garage already does, well or badly. Both have a customer standing in front of you.
Moments two and three are the ones that make the phone ring. Nothing visible happens at either. The car sits on a ramp, the diagnosis is in somebody’s head, and the only route to it is to chase.
Two of the four also aren’t wholly yours to choose. The Motor Ombudsman treats extra work that raises the price as the customer’s decision, and Business Companion says a promised collection time can bind you. Both get their own section below.
What to agree before the keys change hands
The booking conversation decides how many status calls you take on Thursday. Two things get settled there: what the price actually is, and when the customer will next hear from someone.
Start with the price, because the two words in use mean different things. The Motor Ombudsman defines both. “A quote is generally understood to be a fixed price agreed in advance, forming part of the contract between the customer and the garage. An estimate, by contrast, is an approximate indication of cost and may change if further issues are identified” (The Motor Ombudsman).
Read that again as an operator. A quote closes the price. An estimate leaves room for it to move, which is honest when nobody has looked at the car yet. What it doesn’t do is give the garage a free hand later.
Three things belong on the job card at that point:
- Which number to ring, and whether that phone gets answered during the working day. A mobile in a locker until five is not a contact route.
- Whether they’d rather have a call or a message. Plenty of people can’t take a call at their desk but will read a text.
- What “ready” means here. Finished and invoiced, or finished and still to be priced? Only one of those is a car somebody can drive away.
“Ready” said by a technician means the work is done. “Ready” heard by a customer means the car is out front with the keys on the desk. Two different collection times, one word.
A customer who has been told when they’ll next hear from you tends not to ring at eleven. Nobody has measured that, so treat it as an observation rather than a finding.
What do you say when there’s no news?
Name the blocker and give the next checkpoint. A no-news update still carries information, as long as it says what everyone is waiting on. “Still waiting on the caliper, will know more Thursday” is an update. “Your car is being worked on” isn’t, because it answers nothing the customer hadn’t already assumed.
Parts are a common blocker, and a recognised one. Reviewing its 2025 disputes, the Motor Ombudsman pointed to “delays to the supply of parts for repairs preventing drivers from getting their cars back on the road”. It named that among the principal bones of contention in routine and ad hoc maintenance (The Motor Ombudsman).
Notice what that describes. The friction isn’t the delay on its own. It’s the delay plus a driver who has no idea where they stand.
What makes a holding message useful:
- Name the blocker. A part, a diagnosis, a second opinion, a specialist who isn’t in until Monday.
- Give a checkpoint rather than a finish. “I’ll know more by Thursday morning” is a promise you can keep.
- Send it before they ask. A message that lands after the customer has rung is an apology, not an update.
The wording does more work than the channel, and how to write a status update customers read covers that ground properly.
There’s a second reason to send the message you’d rather not send. Silence gets filled with the worst available explanation. Someone who has heard nothing since drop-off assumes the car has been forgotten. That call then takes far longer than the message that would have prevented it.
Authorisation is not an update
Extra work that raises the price is a decision the customer makes, not news the garage delivers afterwards. The Motor Ombudsman is direct about it in its guidance on disputed repair bills. The wording is this: “even where an estimate has been provided, additional work that increases the price should not be carried out without the customer’s authorisation.”
That closes the gap an estimate appears to open. An estimate says the price may move. It doesn’t say the garage can move it alone.
The same expectation sits in the Service and Repair Code, which the Chartered Trading Standards Institute approves. The Institute says the Code covers “completing extra work only with prior agreement”, alongside clear advertising and transparent pricing (Chartered Trading Standards Institute).
The Code’s own promises to consumers include “work completed as agreed” and “invoices that match quoted prices” (The Motor Ombudsman). It was updated on 1 June 2025. One scope point matters: the Code binds businesses accredited to it, and not those that aren’t. The next section is about the Consumer Rights Act instead, which is a separate matter from the Code.
| Type | What it is | Can the price move? | Before going ahead |
|---|---|---|---|
| Quote | A fixed price agreed in advance, forming part of the contract | No | The customer’s agreement to the quoted price |
| Estimate | An approximate indication of cost | Yes, if further issues are identified | The customer’s agreement to the estimate |
| Extra work | Work beyond what was agreed | It’s a new price, not a moved one | The customer’s authorisation, per the Motor Ombudsman |
There’s a commercial reading too. RAC puts the likelihood of a garage finding something else wrong with a car in for a service at 28% (RAC). Among drivers it has happened to, 24% say the unexpected cost puts them off servicing in future. So it’s a common moment, and the one most likely to cost you the next booking.
Now back to the scene at the top of this page. An approval request that can’t be delivered doesn’t merely annoy someone. It stops the job. The car keeps the ramp, the technician moves on, and the bay is out of use until the owner picks up. That customer isn’t ignoring you. They’re at work, and the number calling is one they don’t recognise.
Is a collection time you gave on the phone binding?
Broadly yes, on the CTSI-backed guidance, where the customer relied on it. Business Companion is the consumer law guidance published by the Chartered Trading Standards Institute. On vehicle service contracts it says: “information given in writing or orally to the consumer is binding where the consumer relies on it. This will include quotations and any promises about timescales or about the extent or scope of the service” (Business Companion).
That’s guidance summarising the Consumer Rights Act rather than the wording of the Act itself, and it’s worth reading as such. The same publisher covers timing separately. Where no time was agreed, “the timescale must nevertheless be reasonable” (Business Companion).
Put those together and something practical falls out. “It’ll be ready by three” is a statement about a car. “I’ll call you by three with a time” is a statement about a phone call. The first you can lose to a supplier, a seized bolt or a diagnostic that runs long. The second sits inside your own building.
So the safer habit is also the easier one to keep. Promise checkpoints, not completions, until the job is genuinely finished. It reads like a communication tip. It’s closer to a risk control.
Which customers can’t act on a call?
Two groups. One can’t reach you quickly. The other you’re now holding data about.
Start with the journey, because it’s longer than most garages assume. RAC found that more than a third of drivers who get a vehicle serviced (35%) travel five or more miles to reach the garage (RAC). In rural areas that rises to 48%. Across all the drivers surveyed, 7% travel over 20 miles. Nor is getting there always a drive. The last time they went, 22% depended on a lift, 10% used public transport and 4% paid for a taxi.
Someone on a bus can’t react to “ready now” the way a two-car household can. For them, a message at nine saying “ready by four” beats one at four saying “ready”. Same facts, different notice.
Then the number itself. Taking a mobile so you can text somebody is processing personal data. GOV.UK sets out the principles that attach. The data has to be “used for specified, explicit purposes”, “adequate, relevant and limited to only what is necessary”, and “kept for no longer than is necessary” (GOV.UK). A job card with last year’s numbers still on it sits inside that, not outside it.
What those principles mean for a particular garage is a question for that garage, and what collecting customer phone numbers involves covers them.
Texting has a running price too. Twilio lists an outbound text to a UK mobile at $0.056 per segment on its United States pricing site (Twilio). Its page adds that “text messages are charged per segment”, so a registration plate and a price push one text into two. More in what SMS customer notifications cost.
Setting this up so it survives a busy Tuesday
A routine that depends on one advisor remembering isn’t a routine. Agree the four messages before the week starts, and sending one takes no thought at all.
- Write the four messages once, as templates. Booked in, diagnosed, extra work found, ready. Fill the blanks in on the day.
- Name who sends them. One person per job, usually whoever booked the car in, so nothing gets sent twice.
- Fix the checkpoint times. Two slots a day works: one late morning, one mid-afternoon. Tell the customer which slot.
- Write the blocker down the moment a job stalls. Part, supplier, expected date. That note is the next message.
- Keep the approval call separate. It doesn’t wait for a checkpoint and it doesn’t belong in a template.
The technology is the smallest part of it. All of this works over the phone, by text, or through a tool.
Three of those four messages need nothing from the customer but a scan. Show a QR code when the keys change hands, and the phone in their pocket joins a one-way channel. Upd8All works that way, so the “ready” message lands without the garage ever holding a number. Neither side registers for anything, and no phone numbers or email addresses pass between the business and the customer. Anyone without the app reads the updates in a browser, through Upd8 Go.
The extra-work message is the one it can’t carry. A price and a description of the work won’t fit in 40 characters. The channel runs one way too, so there’s no way for the customer to say yes. Scanning happens across the counter, so a car booked in by phone can’t join a channel until it arrives. The approval call stays a call, whatever sends the other three. How the QR pairing works has the detail.
Start with one week of the phone log
Before changing anything, spend a week counting. Every inbound call that’s really a status chase gets a mark against one of the four moments. Booked in, diagnosed, extra work, ready.
By Friday the pattern is usually plain, and usually one moment does most of the damage. Calls clustering at “diagnosed” mean nobody rings back once the car has been looked at. Calls at “ready” mean “ready” was never defined at booking.
One caveat on what the count will show. A week of calls tells you which message is missing. It doesn’t tell you which one is worth the most to fix, and those aren’t the same answer. A gap at “ready” costs you a late collection. A gap at “extra work found” costs you the bay, the afternoon, and the moment RAC’s respondents linked to being put off servicing altogether (RAC). Fix that one first, even if the log says it happens least often.
Frequently Asked Questions
An estimate isn’t a blank cheque. The Motor Ombudsman states that extra work raising the price “should not be carried out without the customer’s authorisation” (The Motor Ombudsman). Where a technician finds something beyond what was agreed, the expected route is to stop, price it, and ask.
A quote is a fixed price agreed in advance that forms part of the contract. An estimate is an approximate indication of cost that may change if further issues are identified (The Motor Ombudsman). The two get used interchangeably at the counter. Only one of them leaves the price room to move.
Business Companion is the consumer law guidance backed by the Chartered Trading Standards Institute. It says information given in writing or orally binds where the consumer relies on it, including “any promises about timescales” (Business Companion). Where no time was agreed, it says the timescale must still be reasonable. That summarises the Consumer Rights Act rather than quoting it.
No reliable published frequency exists, and most numbers in this topic come from firms selling software. Structure beats a schedule. Make contact at the four moments (booked in, diagnosed, extra work found, ready), plus whenever a checkpoint you promised comes round. That last one counts on the days when nothing has changed.
For a text, yes. A mobile number is personal data, so the GOV.UK principles apply: specified purposes, limited to what is necessary, kept no longer than necessary (GOV.UK). A scanned QR code needs no number. It can’t carry an approval conversation, though, because those channels run one way and cap messages at 40 characters.
Name the part and give the next checkpoint. “Still waiting on the caliper, will know more Thursday” tells somebody where they stand. “Being worked on” tells them nothing. The Motor Ombudsman named parts delays among the principal bones of contention in routine and ad hoc maintenance (The Motor Ombudsman).
