Professional Auto Electrical Repairs

Electrical faults are among the hardest to trace, from parasitic battery drains to intermittent wiring problems. Our auto electrical specialists use professional diagnostic tools to locate the fault quickly and repair it properly.

We repair charging systems, starters, alternators, lighting, fuses and relays, and resolve the dashboard warning lights that electrical faults so often trigger.

Battery Replacement at Your Doorstep

A flat or failing battery should not leave you stranded. We provide fast car battery replacement in London, testing your charging system first to make sure the battery is the real culprit and not an alternator fault.

We fit the correct specification battery for your vehicle, dispose of the old unit responsibly, and reset any electronics that need reconfiguring after the change.
