Battery health directory
Explore our directory of UK-based electric vehicle state of health battery providers.
Welcome to the VRA’s dedicated resource for the UK’s EV battery diagnostics sector.
As the go-to industry body for factory-to-forecourt insights, we understand the critical role that accurate and reliable battery health information plays in the evolving EV market. This directory is a shared resource, intended to connect our members and the wider industry with the leading providers of battery diagnostic solutions.
The directory also showcases providers who are members of the Car Remarketing Association Europe (CARA), which operates its own SOH accreditation scheme.

FAQ’s
Over time, an EV battery holds less of a charge than it did when brand new. This process is called degradation, and its primary measure is capacity fade.
- Capacity fade: This is the natural decrease in your battery’s ability to store energy as it ages.
- State of Health (SoH): This is a key metric that tells you how much of the original capacity remains. A brand-new battery should have an SoH close to 100%, while a degraded one has a lower SoH.
Several things can affect how quickly your EV’s battery degrades:
- Charging habits: Routinely using rapid DC chargers can speed up degradation compared to using slower chargers.
- Temperature: Extreme hot or cold temperatures can negatively impact battery performance and longevity.
- State of charge (SoC): Constantly keeping your battery at very low (under 20%) or very high (100%) charge levels can accelerate degradation. Driving style: Aggressive driving puts more stress on the battery and can contribute to faster degradation.
- Age: Like any battery, an EV’s battery naturally loses capacity over time, regardless of usage.
Protecting your EV’s battery health can maximise its lifespan and range.
- Follow the 20-80% rule: For most daily driving, aim to keep your battery’s charge between 20% and 80%. Many EVs allow you to set a charging limit to make this easy.
- Charge slowly when possible: Use slower chargers for your daily charging needs and save DC fast charging for when you’re on a long road trip and need to get back on the road quickly.
- Avoid deep discharges: Try not to let your battery run completely flat, as this puts a significant strain on it.
- Only charge to 100% for long trips: A full charge is only necessary when you need the full range for an extended journey.
- Drive regularly: Short, regular trips help maintain your battery’s health better than long periods of inactivity.

There are a few ways to get a clear picture:
- Vehicle’s onboard system: Some EVs display the battery’s state of health directly on the dashboard or in the settings menu.
- Specialised diagnostic tools: Professionals use tools that can perform detailed health evaluations by connecting directly to the car’s system.
- Third-party health reports: Services from companies on this page can offer comprehensive battery health reports, providing insights into real-world range and degradation.
