Had small issues with the car since it was purchased, however the seller's garage was never able to diagnose fully. Harrow Service Centre were able to identify the issues within the first few hours, which as it turns out could have been quite dangerous if the car broke down. Wish I would have brought it in for a service here sooner. Would highly recommend the business.

Everyone here is very friendly and helpful. Great service.

I am very careful with my car. Every time before I go to a garage, I do research, read people’s reviews and compare prices due to unpleasant experience with my car fix in the past. I visited Harrow Service Centre for MOT test, unexpected very efficient service and good customer service without potential cost. I was very happy. Since then, I have been to this centre for full service, battery changes. Will change break pads, discs and oil soon. Hopefully, all staffs continue providing reliable works, prices and services.

Update: 24 November 2025MoT and service due for my Rangie Sport last week, so called up HSC (as last year).Booked in for my preferred date, car dropped off in the morning and collected (nice and clean) in the afternoon. Excellent communication - I was called to confirm MoT passed (phew!) and later to say when car would be ready. The bill was very fair and reasonable. Very much like the independent garage ethos. I drive over from Camden to use these guys!------------------------November 2024Having recently relocated to London, I didn't have a regular garage and was in need of an MoT for my Range Rover Sport. I randomly called Harrow Service Centre and yes, they could do it next day. Having established that the only significant fail point was an airbag warning light, this was efficiently rectified. It really is a huge advantage that HSC carry out the MoTs in house, rather than having to send vehicles out.Decided to continue with a yearly service - Yes, no problem! Costs all looked to be entirely reasonable.The service reception team were very knowledgeable, accommodating and communication was excellent throughout. From my experience, HSC is a very well run, professional garage. I would be pleased to thoroughly recommend them.Trevor Madden

Perfect service as always, my car is fourteen years old, so it heeded brake fluid changed and upgrading of worn brake discs and pads. Quoted phone and email price for work was reasonable and kept to.Car was collected in morning returned in the evening, clean and gleaming by a very friendly mechanic who is a great ambassador for the company.Will definitely continue using them, my car deserves it!
