THE 60-SECOND VERSION

Hiring a car diagnostics technician in five steps

  1. Are you a trader, and can I see that in writing?No register covers car diagnostics technician work, so trader status is what your consumer rights hang on — on-Road Testing — some diagnostics require a test drive to replicate issues like vibrations or noise.
  2. How does complexity of the issue change the price?The more pieces involved, the more there is to go wrong. — ask before the quote rather than after.
  3. How does make change the price?It is worth being specific about when you ask for a price. — ask before the quote rather than after.
  4. How does model of the vehicle change the price?The tools decide what is possible as much as the skill does. — ask before the quote rather than after.
  5. What is not included?Electrical Systems Check — this covers the inspection of the vehicle's electrical systems, including the battery, alternator, and wiring — get the exclusions named in the quote, because a car diagnostics technician job is priced on what was agreed and not on what was assumed.

BEFORE YOU BOOK

Check before you book

No register applies

NO REGISTER APPLIES TO MECHANICS IN IRELAND — anyone may repair a car. The statutory thing is the NCT, which is carried out by the national testing service and not by a garage, so a garage cannot issue one. SIMI membership is a trade association rather than a licence, and it gives you a complaints route.

Look for the trader badge and the ID-checked badge on the Locufy profile — both are checked by us, not claimed by the provider.

What to check instead

Motor trade insurance covering your car while it is in their custody, which is separate from their public liability; A written estimate before work starts, and a call before any extra work; Whether parts are new, reconditioned or used, named on the invoice; The guarantee on parts and on labour, separately, in writing; Whether diagnosis is charged separately and whether it is credited against the repair; For a pre-purchase inspection, that the inspector is independent of the seller.

Ask for each of these before you agree a price, and get the answers in the same message as the quote.

Insurance

Expect public liability and motor trade cover for vehicles in their custody. From a company, ask for the insurer, the limit and the VAT number, and ask who actually attends: the team that turns up may be employed, subcontracted or both, and only one of those is supervised by the firm you are paying.

Ask to see the current certificate of insurance — the insurer's name, the limit and the date it runs to.

Trader or private seller

Under the Consumer Rights Act 2022 a trader must tell you they are a trader, and your consumer rights — work carried out with reasonable skill and care, and a cooling-off period on a contract agreed in your home or online — apply to traders and not to private sellers. On Locufy the trader status is shown on the profile.

Look for the trader badge on the Locufy profile, and ask anyone else for it in writing before you agree a price.

VAT

VAT at 13.5%, the reduced rate Revenue publishes for this service. Ask whether the price you were given includes it. A trader under the €42,500 registration threshold does not charge it; one over it must, and must show it separately.

Ask whether the figure you were given includes it, and for the VAT number if they are registered — Revenue publishes the rate for this service. revenue.ie →

“Are you a trader, and can I see that in writing?”

A good answer: No register covers car diagnostics technician work, so trader status is what your consumer rights hang on — on-Road Testing — some diagnostics require a test drive to replicate issues like vibrations or noise.

“How does complexity of the issue change the price?”

A good answer: The more pieces involved, the more there is to go wrong. — ask before the quote rather than after.

“How does make change the price?”

A good answer: It is worth being specific about when you ask for a price. — ask before the quote rather than after.

“How does model of the vehicle change the price?”

A good answer: The tools decide what is possible as much as the skill does. — ask before the quote rather than after.

“What is not included?”

A good answer: Electrical Systems Check — this covers the inspection of the vehicle's electrical systems, including the battery, alternator, and wiring — get the exclusions named in the quote, because a car diagnostics technician job is priced on what was agreed and not on what was assumed.

“Who insures you, and what is the policy number?”

A good answer: Expect public liability and motor trade cover for vehicles in their custody — transmission Analysis — diagnostics can determine if there are issues with the transmission system, such as slipping or unusual noises.

“What do I get in writing, and when?”

A good answer: A written scope and a price before the car diagnostics technician starts, and an itemised invoice after — engine Diagnostics — this includes checking the engine control unit (ECU) for error codes and performance issues.

  1. Look firstComplexity of the issue — the more pieces involved, the more there is to go wrong — that is what the car diagnostics technician is judging on the first visit, and a price given without it is a guess.
  2. Agree what is being doneMake — it is worth being specific about when you ask for a price — put in writing before anyone starts, because it is the document you both read back at the end.
  3. The work itselfModel of the vehicle — the tools decide what is possible as much as the skill does — and anything found on the day that was not in that is priced before it is started.
  4. Check it togetherDiagnostic tools required — the kit required is confirmed before the quote is final — walked against the written scope rather than against the feeling of it, while the car diagnostics technician is still there.
  5. What you are handedThe itemised invoice and any guarantee on the workmanship and the parts, complexity of the issues being diagnosed — a simple job follows a routine; a complex one does not.

AFTER

When the job is done

Keep the invoice and the paperworkAn itemised invoice with the trader's name, the work and the total — on-Road Testing — some diagnostics require a test drive to replicate issues like vibrations or noise, because it is what a buyer's solicitor, an insurer or a lender asks for long after the car diagnostics technician has gone.
Test what was doneElectrical Systems Check — this covers the inspection of the vehicle's electrical systems, including the battery, alternator, and wiring — and something that does not work on the day is theirs to put right there and then.
Ask what the guarantee isOn the workmanship and on the parts, and for how long each one runs — they are usually different. transmission Analysis — diagnostics can determine if there are issues with the transmission system, such as slipping or unusual noises — under the Consumer Rights Act 2022 what was agreed is what can be relied on.
Leave the reviewOnly a booked job can be reviewed on Locufy, which is why the score on a car diagnostics technician's card means something — engine Diagnostics — this includes checking the engine control unit (ECU) for error codes and performance issues.

STEP 1Say it in writing, firstSay what is wrong and what you want done. Under the Consumer Rights Act 2022 the work must be carried out with reasonable skill and care, and defective work put right.

STEP 3Escalate to the body that regulates itThere is no register, so the route is the consumer body and, if needed, the courts.
STEP 4Small claimsSmall claims covers €2,000, once you have asked in writing and given them a chance to put it right.

Hiring a car diagnostics technician: questions people ask

The cost can vary based on the complexity of the issue, the make and model of the vehicle, and the diagnostic tools required. Additional fees may apply if repairs are needed following the diagnostic assessment.

Most car diagnostics jobs take between one to two hours, depending on the issue's complexity and whether further tests are required. Some straightforward checks may be completed in under an hour.

For basic diagnostics, a general mechanic is usually sufficient. However, for issues related to advanced electrical systems or hybrid vehicles, a qualified specialist may be necessary due to the technical expertise required.

Many garages offer emergency diagnostics, but availability can vary. It's advisable to call ahead to check if same-day service can be accommodated, especially during busy periods.

Yes, many service providers allow you to book multiple diagnostics or repair jobs in one appointment. This can save time and may even result in cost savings on labour charges.

Car diagnostics generally do not include repairs or part replacements unless explicitly stated. Additional costs may arise if the diagnostic reveals issues that require further investigation or repairs.
