How to Start Offering Battery and EV Health Checks
Add battery and EV health checks to your services. What’s involved, what you need, and how to sell them.
Battery and EV health checks give customers insight into the condition of their EV or hybrid—state of health, range, and any faults. They’re a way to add value, win EV/hybrid work, and prepare for more electric vehicles on the road. This guide covers what’s involved, what you need (tools, training), and how to offer and sell them.
Start with what you’re allowed to do
1. What customers get from a health check
A typical check might report: HV battery state of health (e.g. % capacity), any fault codes, cooling system status, and (where available) range or degradation. That helps customers planning to sell, part-exchange, or keep the car long term. Frame it as "know your battery’s condition"—useful for resale and peace of mind.
2. What you need: tools and training
You need diagnostic equipment that can read EV/HV data—OEM, aftermarket (e.g. Launch, Autel, etc.), or manufacturer-specific tools. Training (at least Level 2, and Level 3 if you’re doing HV diagnostics) is usually required by insurers and makes the results credible. Check that your policy covers EV health checks and that you’re not exceeding what you’re qualified to do.
3. How to offer and sell them
Offer as a standalone "Battery / EV health check" (e.g. £50–£150 depending on depth and market) or as part of a service package. Promote to EV and hybrid owners: "Before you sell or part-exchange, get a battery health report." Use digital health checks and video or photo inspections to show the customer the results—builds trust and supports the price. List it on your website and Google profile so EV owners can find you. List your garage on AutoChain to appear when drivers search for EV-trained workshops.
4. Be clear what the check does and doesn’t do
Tell customers what’s included: e.g. "We read battery state of health, fault codes, and cooling system status. We don’t open or repair the HV battery." If you find faults, explain what they mean and what the next step is (e.g. "Recommend a main dealer or HV specialist for that"). Don’t overclaim—accuracy and honesty build trust and reduce comebacks.
