Servicing and your warranty
You don't have to go back to a main dealer to keep a new car's warranty. Competition rules let independent garages service cars during the manufacturer warranty. What Car? explains that an independent service is fine "provided it adheres to the car maker's servicing schedule and uses genuine parts". The UK's current rules, the Motor Vehicle Block Exemption Order, came into force on 1 June 2023.
That's how we work: the manufacturer's schedule, genuine and matching-quality parts, and a full record of what was done.
Some extended warranties sold by car makers have their own terms, and these can ask for dealer servicing. If your car has one, check the small print or send it to us and we'll take a look.

We tell you what we find
If anything else needs attention, we tell you what it is and what it would cost. Nothing extra is done without your say-so.
Diagnostics and warning lights
If a warning light comes on, or the car doesn't feel right, bring it in. We find the cause first, then tell you what the repair involves and what it will cost before any work starts. See car diagnostics.
Air conditioning
If the air con has stopped blowing cold, it may need a regas, or there may be a fault in the system. We regas car air conditioning and repair it when it isn't working. See air con regas and repairs.
Checking a car before you buy it
Buying a used car? We do pre-purchase inspections, so you know what you're getting before you hand over the money. Call 01908 371693 to arrange a time.

Reviews
What customers say
I have used this garage for over 10 years & had, bmw's, an Aston Martin, range rover and mini gp3 all serviced & repaired here, brilliant workmanship and attention to detail, couldn't recommend any higher.
Top class garage, Martin & team are very welcoming & knowledgable in their profession. And will offer great advice. I know a lot about cars too so I felt on par with them. I would definitely recommend & I will use again. Martin comes across as a perfectionist, reminds me of myself 😆 I really don’t leave reviews but they deserve it. Steve - Blue Focus ST
