Carolyn Anderson

Can’t recommend Joe highly enough. Went out of his way to come and fix an issue on my car within 4 hours of me calling him. Very quick and well priced service and very skilled at his job, which is a rare combination!

Max Chamberlain

I was incredibly impressed with the service provided by Joseph - he was great to get in touch with and arrange an appointment with, came out to look at my car within a couple of days of making contact. He was professional and very knowledgable, and I am incredibly grateful for the work he carried out - in less than an hour, he had resolved all of the issues that the BMW dealership were telling me I needed new parts supplying for - Joseph has saved me hundreds of pounds. Will definitely be using Joseph again if I run into any further issues on my car.

David Allsopp

Life saver, my car broke down and would not start, i need it daily to get to work due to location. After a week and one other garage who could not help I contacted JHW, he had availability the next day and fixed it quickly and at a very reasonable price.

Ashley Taylor

Great communication and fault testing & diagnosis. Very knowledgeable individual that's keen to help and resolve. Will recommend and use again for sure!

Tony Parker

I had an issue with my hyundai i20. The lambda sensor kept coming on, despite multiple garages allegedly fixing the E.C.U, alternator, and a long list of other unnecessary things to try to rectify it. Joe told me it was the AC compressor which I'd asked other garages to check many months before, my E.C.U was also at the wrong voltage. So the work cost a lot of money for them to fix but they did it at short notice. I had a few issues after, but again they were sorted out. Joe is very knowledgeable and polite. Thank you jhw!

Anne-Marie Fox

Absolutely incredible! Gentleman fixed my fiat punto window in minutes! Lovely gent and even did extra protection on other wires to make sure they wouldn't split in the near future. 100% recommend for service, price and customer service.
