Vehicle Repair Work Order Template (UK)
Updated on 9 August 2026
A vehicle repair work order is the document a garage raises before and during a repair: what the customer reported, what the technician found, an itemised estimate, and the customer's authorisation to proceed — distinct from the invoice, which bills for work already completed.
The UK doesn't have a single statutory written-estimate mandate the way some US states do, but the Consumer Rights Act 2015 already does real work here: every contract to supply a service carries an implied term that the trader performs it with reasonable care and skill, and anything the garage tells the customer about the service — including a quoted price — becomes a binding term of the contract if the customer relied on it. A work order that records the estimate and the customer's authorisation in writing is the practical way to make that binding information clear on both sides, not just a paperwork nicety.

Get authorisation before the meter starts running
The Consumer Protection from Unfair Trading Regulations 2008 treat demanding payment for goods or services the customer never agreed to as an unfair commercial practice. A work order that records exactly what was authorised, by whom, and when — with a not-to-exceed ceiling for the initial estimate — protects the garage if a customer disputes a charge, and protects the customer from being billed for work they didn't approve.
Treat the estimate as a binding term, not just a courtesy
Under section 50 of the Consumer Rights Act 2015, what the garage tells a customer about the service — including a price estimate — becomes a term of the contract if the customer took it into account when deciding to go ahead, subject to any qualification given at the same time. That makes an accurate, itemised estimate a real legal commitment, not just useful information, and it's why any change to it should be agreed and recorded, not assumed.
Handle a mobile callout differently from an in-garage job
If a mechanic attends the customer's home or workplace rather than the customer bringing the vehicle to the garage, the job may be an off-premises contract under the Consumer Contracts Regulations 2013. Where the customer specifically asked for an urgent repair or maintenance callout, that specific job is generally exempt from the usual 14-day cancellation right — but any additional work the mechanic offers to do on the same visit, beyond the requested urgent repair, is not covered by that exemption and can carry its own cancellation right. Recording whether the job was an urgent callout the customer requested, and treating any extra work as a separate authorisation, keeps this distinction visible rather than blurred.
Disclose non-OEM and used parts
Many repairs legitimately use aftermarket, reconditioned, or used parts rather than original-equipment-manufacturer parts. Disclosing that on the work order, rather than leaving it to be discovered later, avoids a dispute over something the customer may have had no objection to if they'd simply been told.
Record diagnostic findings separately from the customer's complaint
"Engine warning light on" is what the customer reports; the specific fault code and diagnosis is what the technician actually found. Recording both separately protects the garage if the diagnosis changes once the vehicle is on the ramp, and gives the customer a genuine record of what was wrong, which matters if the same fault recurs.

- Reported problem and diagnosis
- Separates what the customer reported from what the technician found.
- Itemised estimate
- Lists parts and labour with a total estimated price before work begins.
- Authorisation to proceed
- Records how, by whom and when authorisation was given, plus a not-to-exceed ceiling.
- Off-premises callout note
- States whether this was an urgent callout requested by the customer, and flags any additional work as separately authorised.
- Parts disclosure
- States whether OEM, aftermarket, reconditioned or used parts will be used.
UK compliance notes
This covers the general consumer-protection position; garage-specific licensing or accreditation schemes (such as the Motor Ombudsman's Code of Practice) may add further requirements.
Perform the work with reasonable care and skill
Every contract to supply a service in the UK carries an implied term to that effect, which cannot be excluded by the garage's terms.
Consumer Rights Act 2015, section 49Treat information given to the customer as binding
What the garage tells the customer about the service, including a price, becomes a term of the contract if the customer relied on it, subject to any qualification given at the same time.
Consumer Rights Act 2015, section 50Don't charge for unauthorised work
Demanding payment for goods or services the customer never agreed to can be an unfair commercial practice under the Consumer Protection from Unfair Trading Regulations 2008.
Check the off-premises cancellation position for mobile callouts
An urgent repair callout the customer specifically requested is generally exempt from the standard cancellation right, but additional work offered during the same visit is not automatically covered by that exemption.
How to complete a work order
- Record vehicle and customer details. Add the vehicle description and the customer's contact information.
- Log the problem and diagnosis. Record what the customer reported and what the technician found.
- Build the estimate. List parts and labour with an itemised estimated total.
- Get authorisation. Record how and when the customer authorised the work, and set a not-to-exceed ceiling.
- Note the job type. State whether this was an in-garage job or an off-premises urgent callout.
Frequently asked questions
Is a garage legally required to give a written estimate before starting work?
There's no single UK statute requiring a written estimate the way some US states do, but a garage that quotes a price and the customer relies on it makes that price a binding contract term under the Consumer Rights Act 2015, and doing unauthorised extra work risks breaching consumer-protection rules against unfair commercial practices. A written estimate and recorded authorisation is the practical way to avoid disputes either way.
What's the difference between a work order and an invoice?
A work order is raised before and during the repair to capture the estimate and the customer's authorisation. An invoice bills for the work actually completed. Use a work order to start the job and a separate invoice to collect payment.
Can a mobile mechanic just start extra work while at my house?
Not without your separate authorisation. If you called them out for an urgent repair, that specific job may be exempt from the usual cancellation right, but any additional work offered on the same visit isn't automatically covered by that exemption and should be treated as its own authorised job.
Do I have to be told if a garage uses a used or aftermarket part?
It's best practice regardless of whether a specific rule requires it in your situation — a customer who finds out afterwards that non-OEM parts were used without being told has a legitimate complaint, even where the part itself was a reasonable choice.
What happens if the real repair cost is higher than the estimate?
If the extra cost would take the total above the not-to-exceed amount you authorised, the garage should get your agreement before doing the additional work, rather than billing for work you never approved.
