FAQS
The Basics
Why Voltest with Bell & Colvill? There are no monthly subscriptions or expensive kits; just a straightforward pay-per-test model, delivered by an established and trusted dealer since 1970.
How do I access the service? Ways to get your battery health certificate:
- For Personal Use: Simply book an appointment and visit our Guildford branch, where our technicians will perform the scan while you wait.
- For Business Use: We understand the need for efficiency; we will come to you at your dealership or site to carry out the service on-site.
Why would this benefit my business? Voltest is a dual-purpose tool designed to drive both showroom profitability and workshop efficiency. By removing "battery anxiety" from the equation, you provide the transparency today’s EV buyers demand, leading to faster stock turnover and protected margins. Whether you are using it to justify a premium price point on the forecourt or offering it as a high-value bolt-on service in your workshop, Voltest reduces the risk of unforeseen battery issues and ensures you are maximising the value of every hybrid and electric vehicle in your care.
Process & Compatibility
How long does the process take? The process takes less than 15 minutes. It is an efficient plug-and-play scan that fits seamlessly into your existing vehicle prep or health checks, so your business and technicians can keep working without any disruption.
What vehicles are supported? Our coverage is constantly expanding and currently includes the vast majority of EVs and Hybrids on the UK market. You can view our full, up-to-date compatibility list here.
How does this differ to my current diagnostics tool? Standard diagnostic tools are typically generic, reactive, and flag "fault codes" once a problem has already occurred. Voltest is individually tailored to each vehicle model to provide a true deep-dive analysis. We provide data your current kit can’t - such as cell voltages and precise degradation metrics - moving you from reactive repairs to high-value preventative maintenance. Critically, Voltest is as much a sales tool as it is a diagnostic one. It generates a retail-ready certificate designed to be handed to a customer to close a sale.
Pricing & Competition
How much is the Voltest service? Voltest is £49.99 per test, which includes a digital certificate. (Premium hard-copy certificates are available at an additional cost).
What’s the difference to the competition? Unlike other providers, there is no expensive kit to buy or monthly subscriptions to manage. Our pay-by-test solution is more cost-effective and provides a visually premium certificate that is specifically designed to be retail-friendly and easy for a customer to digest.
Revenue & Future-Proofing
How much can I sell it for? Because of our partnership’s competitive regional pricing, you have the flexibility to either include the certificate in the vehicle price to justify a higher margin or offer it as a premium add-on. Our volume-negotiated rates allow you to remain highly competitive while maintaining healthy profits.
How would I offer this as an additional service? There are several ways to turn battery health checks into a revenue stream:
- Service Bolt-on: Offer a "Battery Health MOT" as a premium add-on during routine maintenance.
- The "EV Service Day": Market specific days for EV owners to receive a comprehensive health check and certificate.
- The Inside Edge: Manufacturers often keep battery data locked away. We provide the transparency they don’t want you to have, allowing you to give your customers the full picture of their vehicle’s health.
We don’t stock or service EVs – is this for me? Absolutely. In fact, this is the perfect time to start. The fear of "unknown" battery health is the biggest barrier to entry for many businesses. Voltest gives you the technical confidence to trade, stock, and service EVs without the risk. It’s a low-cost, high-impact way to future-proof your business and capture the ever-growing market.
