Tatnall EV Aftersales Insight

EVs Are Changing Aftersales Forever

But the biggest opportunity still sits inside the eVHC process.

By Jon Tatnall | Automotive Retail Consultancy & Operational Support

The UK automotive industry is moving rapidly towards electric vehicles.

And while the headlines often focus on:

battery technology
charging infrastructure
government targets
EV sales growth

…the real operational challenge for dealerships sits inside aftersales.

Because EVs are changing the entire workshop revenue model.

Inside This Insight

Why the traditional aftersales model is changing

EVs are reducing routine maintenance demand and increasing the importance of every customer touchpoint.

Where EV revenue is shifting

Tyres, suspension, diagnostics, battery health, software, ADAS and thermal management are becoming more important.

Why eVHC conversion matters more than ever

Fewer workshop visits mean dealerships cannot afford weak communication, poor follow-up or lost identified work.

The Traditional Aftersales Model Is Changing

Historically, workshops relied heavily on recurring maintenance revenue from:

oil changes
filters
exhaust systems
timing belts
engine servicing
traditional wear-and-tear components

But EVs remove huge amounts of that work completely.

£175

less annual workshop revenue per EV compared to ICE

£210m

estimated UK reduction in traditional servicing revenue

And there is another major factor. Most EVs are now moving towards:

bi-annual servicing
extended service intervals
lower routine maintenance schedules

Fewer workshop visits = fewer natural sales opportunities. That changes everything.

The Revenue Hasn’t Disappeared — It Has Shifted

The important point is this:

EV aftersales revenue is not disappearing completely. It is evolving.

The revenue is now moving towards:

Tyres

Suspension

Thermal management

High-voltage diagnostics

Battery health

ADAS calibration

Software diagnostics

Cooling systems

Charging systems

Because EVs may have fewer moving engine parts, but they are:

significantly heavier
far more software driven
technically more complex
and still create wear in key areas

For example:

EV battery weight places more strain on tyres and suspension
regenerative braking can create brake corrosion and seizure issues
thermal management systems create high-value repair opportunities
ADAS and electronic systems require specialist calibration and diagnostics

The work is still there. It just looks different.

This Is Why the eVHC Process Becomes Critical

With fewer service visits per year, every workshop interaction matters more than ever.

And that is where the eVHC process becomes absolutely vital.

Modern eVHC systems already allow technicians to:

identify faults
upload photos
create videos
highlight Red and Amber work
present visual evidence to customers

The problem is not usually the technician. The technician often identifies the work correctly.

The issue is what happens next.

Technicians Find the Work — But It Still Needs Selling

This is one of the biggest operational gaps I see developing within EV aftersales.

The technician:

identifies the tyre wear
spots the suspension issue
notices the brake corrosion
sees the cooling system concern

…but unless the customer properly understands:

the importance
the safety risk
the future cost
the technical reasoning

…the work often gets declined. This is where service advisors become incredibly important.

Service Advisors Now Need EV Knowledge — Not Just Booking Skills

In my opinion, service advisors can no longer simply:

book vehicles in
present prices
and process invoices

They now need genuine EV understanding.

Not technician-level diagnostic training, but enough knowledge to confidently explain:

why EV tyres wear differently
how regenerative braking affects brake systems
why thermal management matters
why suspension wear increases on heavier EVs
why battery cooling systems are critical

Customers often believe: “EVs don’t need servicing.” But that simply is not true. They need different servicing.

Technicians May Actually Be the Most Trusted Salespeople in the Building

This is where I think the industry has a huge opportunity.

Personally, if a trained technician explained to me:

what the issue was
showed me visual evidence
explained the risk clearly
and talked me through why it mattered

…I would probably be far more likely to authorise the work.

Why?

Because technicians carry trust and credibility.

Customers see technicians as:

experts
engineers
problem solvers
professionals fixing the vehicle

Not salespeople.

This is exactly why technician videos, eVHC photos, visual explanations and direct technician communication can massively improve conversion rates.

The conversation becomes educational rather than transactional. And that changes customer behaviour completely.

The Real Revenue Risk for EV Workshops

As EV servicing intervals increase, workshops simply cannot afford weak eVHC conversion.

Because there are:

fewer customer touchpoints
fewer routine maintenance opportunities
fewer chances to recover lost revenue later

If the dealership misses the opportunity today, the customer may not naturally return for another 2 years.

That makes advisor training, eVHC process, customer communication, follow-up discipline, pricing speed and technician engagement more important than ever before.

EV Aftersales Is Becoming a Diagnostic & Communication Business

The industry is shifting away from:

“replace simple mechanical parts”

towards:

“diagnose, explain and justify technical work.”

That means aftersales success will increasingly depend on:

technician quality
advisor knowledge
process execution
customer trust
communication skills

Not simply workshop loading alone.

Why Training Now Matters More Than Ever

Many service advisors were trained in a traditional ICE environment.

But EVs require a different conversation.

That means dealerships now need:

EV awareness training
eVHC presentation coaching
customer communication development
consultative aftersales skills
confidence in explaining technical findings

Without that, the workshop may identify the opportunity, but still fail to sell it.

The Opportunity Is Already Sitting on the Ramp

At Tatnall Automotive Consultancy, we believe one of the biggest revenue opportunities in modern aftersales sits inside eVHC conversion, advisor development, technician communication, process consistency and EV customer education.

That is exactly why we created the eVHC Revenue Opportunity Calculator.

The calculator helps dealerships estimate lost revenue opportunity, Red and Amber conversion gaps, workshop revenue leakage and additional revenue potential from improved eVHC performance.

Because as EVs become more common, workshops will not survive purely on traditional servicing models anymore.

The dealerships that win will be the ones that:

educate customers better
communicate technical findings clearly
train advisors properly
and convert more of the work already being identified every single day
