Customer Reviews
What Portsmouth Drivers Say
Real reviews from real customers — straight from Google.
"After my Mini failed its MOT, I called three different electricians — all of them said they couldn't help without even trying. Then I contacted Auto Electrics, and what a difference! The electrician took the job on straight away and fixed it."
Google Review
"Fixed a long standing defect on my indicators on the same day, despite the fact I didn't deliver the car until the afternoon. Price was far less than I expected. Would highly recommend for any car-related electrical defect."
Google Review
"Fast and spot on service and the car is back to where it needs to be. Can't rate the service enough, communication was excellent and definitely worth the price. Will be returning customers!"
