EV Repair and High-Voltage Diagnostics

Battery, charging and warning light faults on electric cars, diagnosed and repaired at component level. Often a repair, not a full EV battery replacement.

Component level means fixing the one faulty part, not swapping the whole unit.

Took my daughters fiat 500 hybrid in and without knowing the problem they said from the start we can sort it out. Even though it was a new job they haven't had experience with. A week later it was done… fiat wanted £2660 to fix it… EV did it for a fraction of the price and did it with a smile, saying we will fix it and they did. 100% recommend.

My Lexus had a problem where it won't start. So I had a recovery take to my local garage and after three months couldn't resolve it and told me to take it to a specialist. So I did, it was there a month and they still didn't fix it. Than I phoned Hybrid Battery Uk, they picked it up on a recovery truck and began work straight away. They sent me videos of the work they where doing and had it done in two days. I can't thank them enough they kept in touch with me the whole time, unlike the others. Just wish I had gone there first. Highly recommend.

I called several auto electric shops, and they were all very rude, expensive, and uninterested. These guys here were super friendly, didn't create any difficulties, and charged a very very fair price. They solved my problem (rear fog light) in less than an hour.

great service, quick, came to me when my car was disabled. Saved me a TON of time, money, and headaches compared to the dealership

Too honest for his own good. I really appreciate the honest advice about the electric car.

Hicham S.

Taz is very knowledgeable with hybrid batteries and cars. Honesty is his watchword. He took his time to listen to me and diagnosed my car. He didn't complicate or exaggerate the problem. I'll highly recommend him.

This company is a magic in hybrid technology. I am very impressed, fast and reliable with the best customer services, good price. I encourage everyone to use this company.

Lawson M.

Brilliant and quick service, really helpful and kept me updated via WhatsApp and sent pictures of the work to keep me updated.

Zane A.

Couldn't have asked for a more better and professional service from these guys, highly recommended to anyone with a hybrid issue. Go above and beyond to repair the issue.

EV repair questions

Often not. Many faults come from individual modules, contactors, sensors or cooling parts, which can be repaired on their own for a fraction of the cost.
