We run an honest business built around our customers. After working in the industry for a number of years, we noticed a gap in the market for an auto care service that provided an excellent quality of service, at a low cost, whilst maximizing convenience to customers. 

We can take care of car diagnostics, mechanical repairs and upgrades, electrical repairs and upgrades, carbon cleaning, car remapping, valeting, vehicle detailing and fleet servicing, to the highest possible standard. For a reasonably priced, professional and convenient Mobile Mechanic & Auto Electrician, One Stop Autos has got you covered.

Why Choose One Stop Autos?


We know the importance of excellent customer service. So, you can rely on us to arrive on time and complete any work you require to the highest standards.


On average our repairs & servicing are 1/3 of the cost in comparison to main dealer prices

Last year in 2022 , the cheapest price we found  for a skilled Level 4 Advanced Diagnostic Technician in a dealership was £148+ VAT per hour…

Our price per hour of diagnosing was just £60 all in!


We ensure that all parts we use are high quality, OEM parts and they come with a 1-year warranty.

I brought my car to One Stop Autos after it developed an unusual electrical fault. Marty went above and beyond to both diagnose and fix the issue. I found him to be genuine and honest and would have no hesitation in recommending him to family and friends. If you want your vehicle to be looked after by someone you can trust, you'll be in safe hands with Marty.

I needed a mph fascia for a speedometer on a car I was importing. Marty couldn't have been more helpful and got the work done so quickly and provided all the documentation I needed to get the Conversion cert to register the car with the DVLA.
