Electronic Vehicle Health Checks generate a goldmine of aftersales opportunity. Every amber advisory item represents work that the customer genuinely needs — not a hard sell, but a legitimate safety or maintenance recommendation backed by a technician’s assessment. Yet across the UK, the average conversion rate on EVHC amber work sits below 20%. That means 80% of identified, revenue-generating work simply never happens.
Why amber work goes unconverted
The problem isn’t customer reluctance. Most vehicle owners, when presented clearly with what needs attention and why, are willing to authorise the work. The problem is the gap between the health check and the follow-up.
Here’s what typically happens: a technician completes the EVHC, flags several amber items, and the service advisor attempts to contact the customer by phone. The customer is at work, in a meeting, or simply doesn’t answer an unknown number. The advisor leaves a voicemail — or more often, moves on to the next job. The amber work goes into a spreadsheet, and nobody follows up again.
That cycle repeats hundreds of times per month across a dealership group. Each missed follow-up represents an average of £840 in lost workshop revenue.
The timing problem
Speed matters enormously with EVHC follow-ups. A customer who hears about their amber items within two hours of their service visit is far more likely to authorise the work than one who gets a call three days later. By then, they’ve mentally moved on. The urgency has faded. The connection between “my car was just inspected” and “I should get this fixed” has weakened.
Yet most dealerships can’t achieve that two-hour window consistently. Service advisors are juggling vehicle handovers, customer queries, and warranty claims. EVHC follow-ups are important but never urgent, so they slip down the priority list.
What effective EVHC follow-up looks like
The dealerships converting at 34% or above share three common practices:
Immediate, automated contact. Within hours of the EVHC completion, the customer receives a clear, personalised summary of what was found. Not a technical report — a plain-English explanation of each item, why it matters, and what happens if it’s left unaddressed.
Multi-channel communication. The initial message goes via email with a detailed breakdown. If there’s no response within 24 hours, a follow-up SMS provides a concise reminder with a direct booking link. This combination consistently outperforms phone-only or email-only approaches.
Frictionless booking. Every message includes a one-tap option to book the work. No phone calls required, no forms to fill in, no back-and-forth to find a suitable date. The customer sees the advisory items, decides to act, and books — all in under 60 seconds.
How AI transforms the process
AI-powered EVHC follow-up automates the entire workflow:
- Instant trigger — the moment an EVHC is completed in your service management system, the follow-up sequence begins automatically
- Intelligent messaging — AI translates technical advisory codes into customer-friendly language, explaining each item in terms the owner understands
- Conversational replies — when customers reply with questions (“Is this urgent?”, “How much will it cost?”, “Can I wait until next month?”), AI handles the conversation naturally and accurately
- Automatic escalation — customers ready to book are connected directly to your workshop scheduling system, while those needing more persuasion continue receiving appropriately timed follow-ups
The revenue impact
Consider a dealership group completing 800 EVHCs per month with an average of 2.3 amber items per check. At an average value of £840 per conversion:
- At 18% conversion (industry average): 144 conversions = £120,960/month
- At 34% conversion (with AI follow-up): 272 conversions = £228,480/month
- Difference: £107,520 additional revenue per month
That’s over £1.2 million in additional annual workshop revenue from work that was already identified and waiting to be sold. No new customer acquisition required. No additional marketing spend. Just systematic follow-up on opportunities your technicians have already created.
Getting started
The most effective approach is to start with a pilot. Choose one site, connect your EVHC data feed, and run automated follow-ups for 30 days. Measure the conversion rate against your historical average. The data speaks for itself — dealerships that pilot AI-powered EVHC follow-up almost always roll it out group-wide within 60 days.
Your technicians are already doing the hard work of identifying the opportunities. The only missing piece is consistent, timely follow-up that turns those amber items into booked workshop time.
