EV & Hybrid Repairs & Servicing for Milton Keynes, Towcester, and Silverstone

NMJ Service Centre is your local specialist EV & hybrid repair centre

Electric vehicles are changing fast. The workshops looking after them need to keep pace. At NMJ Service Centre, we’ve invested in the training, qualifications, and diagnostic capability to do exactly that, making us one of the most genuinely equipped independent EV and hybrid repair centres serving drivers from across Milton Keynes, Towcester, Buckingham, Silverstone, Alderton, and the villages in between.

Our EV Expertise

Repairing electric vehicles isn’t just a sideline for us. Our technicians hold IMI Level 4 EV qualifications, which is the industry benchmark for working safely and competently on high-voltage vehicles, alongside our F-gas certification. That training, combined with years of main dealer-level experience across premium brands, means we approach every EV repair with the same rigour and accuracy you’d expect from a manufacturer’s network.

We have particular depth of experience with Tesla, and work across all major electric and hybrid models.

What We Repair

Repairs are the core of our EV offering, and it’s where specialist knowledge makes the real difference. We diagnose and fix:

• Charging system faults and failures
• High-voltage electrical issues
• Battery performance and cooling system concerns
• Warning light investigation and fault code diagnosis
• Ancillary system repairs across all major EV platforms

Accurate diagnosis comes first. EV systems are complex, and getting it wrong is costly. We use manufacturer-level diagnostic tools and take the time to identify the root cause before any work begins.

Why Choose NMJ Service Centre for Your EV?

• Our qualified team. IMI Level 4 EV and F-gas certified technicians, not general mechanics who occasionally work on EVs.
• Dealer-trained. Every technician has a main dealer background, bringing that standard of knowledge to an independent setting.

• Locally based. Convenient for drivers across Milton Keynes and the surrounding villages, with easy access, ample parking, and a comfortable place to wait.
• Tesla specialists. With strong links to our sister EV sales operation, we’re well-versed in Tesla ownership, from the vehicles themselves to what their owners expect.
