Frequently asked questions

Why should I book a diagnostic check?

When you book a professional diagnostic test, the garage will use advanced diagnostic tools to find problems you otherwise might not be able to spot. A qualified technician can pinpoint the exact cause and advise you on the right solution for your car.

What is a diagnostic test?

During a professional diagnostic check, a technician will use specialist software to analyse your car’s computer systems.

They do this by connecting a code reader to your car’s engine control unit (ECU) to identify any fault codes.

Think of the test like a health assessment for your engine, which allows the technician to spot issues which could be harder to find with a manual inspection.

When a fault is detected during the check, technicians can learn which components are affected, how serious the problem is and what the cause of the problem could be.

Which issues can a diagnostic test detect?

A diagnostic check can help to identify a range of issues, relating to the following components amongst others:

-Engine
-Battery
-Brake system
-Alternator
-Gearbox
-Exhaust
-Airbags
-Suspension

What do the Tier badges mean?

We recognise the very best performing garages in your area with a Silver, Gold or Top Tier badge. These badges help you spot garages that deliver customer service that goes above and beyond for drivers, offering great value, high standards and satisfaction/high ratings.

When do I pay for my appointment?

We never ask for payment details upfront.

Once you’ve chosen your garage, you deal with them directly from start to finish, paying only after the work is complete – giving you full peace of mind.

Some mobile technicians may request some commitment or payment upfront to cover the costs of them coming out to you.

Can I compare garages another way?

Absolutely. True value looks different to everyone so, whether you want the nearest garage, the best-rated option or the lowest price, you can use the Sort By menu in the top-right corner to compare results by Price, Distance, Availability or Reviews - whatever matters most to you.

How do I reschedule my appointment?

You can change your booking details right up until the appointment date. You’ll find instructions in the confirmation email you received or in your BookMyGarage account. Your chosen garage will contact you to acknowledge the amendment and re-confirm your booking.

What does ‘BMG Verified’ mean?

Garages marked as BMG Verified have been physically visited by our team and meet our clear service level agreement standards for ratings and reliability.

Why do some garages have lower prices than others?

Garages set their own prices to deliver great value for every driver, based on their location, costs and special offers. We show every price upfront, so you can decide what represents the best value for you without any hidden fees or surprises.

Is the cheapest option always the best?

The best option for you will depend on your priorities. That’s why we show prices, ratings, availability, distance and everything else you need to find the right value for you, not just the lowest price.

How do you decide which garages to show me first?

We recommend the garages we deem most relevant for you based on your selected product, postcode and the reviews of garages in your area, prioritising BMG Verified and Silver, Gold and Top Tier garages for added peace of mind.

You can change your filters anytime if one factor is more important to you than others – full transparency, full control.
