The mandate has been set, delayed, reinstated, flexed and briefed against for three years, and the next review isn't due until early 2027. Retailers are still expected to commit capital, capability and stock against it. Everything that follows lands in the building regardless of where the policy finally settles — so this is what an EV actually costs a retailer, and what is worth deciding while the number is still unknowable.
The legal requirement for 2026 is unchanged: a third of every manufacturer's UK sales must be battery electric, stepping to 38% in 2027, 52% in 2028, 66% in 2029 and 80% in 2030. That is the law as it stands this morning.
The widely reported cut — 80% down to 50% by 2030 — has not been enacted. It has been briefed, welcomed by the trade bodies, and treated in a great deal of commentary as settled. It isn't. The government's own review is not due to be published until early 2027, and as recently as last week a government backbencher restated the commitment to end petrol and diesel sales in 2030. In the same week the IMI called for an early review, having found that four in five of the workforce were not confident the 2030 targets could be delivered.
So the honest position for anyone running a site is this: the direction is probably softer, the date is unknown, and the number is unknowable. Which is an awkward thing to build a technician training plan, a charging installation and a used EV stocking policy around — and yet all three decisions are due now.
Notice who carries that. The policy argument runs between government, the SMMT and the manufacturers. Not one of those parties owns a workshop, a used forecourt, or a sales executive who has to answer a range question on a wet Tuesday. Every consequence of the uncertainty is settled at retail level, by people with no seat in the conversation producing it.
The debate is held at OEM and government level. The consequences are settled in the building.Why the retail read on this is the one nobody publishes
From late February the conflict in the Middle East disrupted flows through the Strait of Hormuz and took Brent crude from around $70 to temporary peaks above $100. Diesel peaked near 192p in mid-April; petrol near 159p in late May.
The effect on EV interest was immediate and well documented. Startline's May tracker found 92% of dealers believed the pump price surge was making more buyers think about switching to electric. Auto Trader recorded a 28% rise in leads on new EVs and 15% on used. Leasing enquiries rose around a third, and some used EV specialists reported sales up by as much as 60%.
That was genuine demand. It was also borrowed against a geopolitical event, and the event has largely reversed. Shipping through the Strait has recovered substantially, Brent is back around $72, and pump prices have eased to roughly 151p for petrol and 167p for diesel.
The operational question this leaves is uncomfortable and worth asking honestly: how much of your current used EV stock was bought at spring money, on spring demand, against a fuel price that no longer exists? A site that read March to May as structural change in consumer preference has a valuation problem sitting on its forecourt right now, and it will surface in the used book rather than in the decision that caused it.
The case put to retailers for electrification is built on new car margin, mandate compliance and future-proofing. These four sit underneath it, and none of them is usually costed.
High voltage work is tiered and enforced. Level 2 covers routine maintenance with the battery isolated; Level 3 covers fault diagnosis and repair on live high voltage systems; Level 4 covers repair of the battery pack itself. Manufacturers concentrate that top capability in a limited number of designated centres — Volkswagen, for instance, established Battery Competence Centres inside a small number of existing retailers, staffed by qualified high voltage experts.
Which means a site without Level 4 doesn't lose battery work to an independent. It loses the customer to another retailer in the same brand — who then holds the booking conversation, the courtesy car, the health check, the tyres they notice while it's on the ramp, and the trade-in conversation that follows. You have not lost a repair. You have introduced your customer to a competitor and paid for the introduction.
When the work moves, so does everything wrapped around it: who books it, who sets the expectation on timing, who explains what is and isn't covered, who handles the customer when the part is delayed, and who is standing there when the vehicle is collected.
That last position is where upsell actually happens in a workshop — not on a menu, but in a conversation with someone who already trusts you. Hand the job across and you keep the liability for the relationship while another site collects the revenue from it. The warranty claim, meanwhile, is administered by whoever did the work, which is also whoever now holds the vehicle's most recent record of what it needs next.
EVA England's surveys found nearly 40% of EV drivers rated their dealership experience as poor or in need of improvement, with many reporting that the people selling the cars didn't know enough about them and that misinformation on range and charging was common.
This is not a personality problem and it is not fixed by enthusiasm. It is a training and product-exposure problem, and it compounds: an executive who has been caught out once on a charging question will steer the next customer towards the powertrain they can defend. That looks like weak EV demand in the reporting. It is actually a capability gap being recorded as a market signal — and it is the single cheapest thing on this list to fix.
Pre-registration is the pressure valve on a target that can't be met by retail demand. It rose again in June as the network chased half-year numbers, with volumes among the top ten pre-registered EVs up more than a quarter after falling sharply the month before, and average prices on those units down around 17% to roughly £21,600.
Every one of those is a nearly-new car that competes with the new one you are trying to sell, at a price you cannot match, on your own forecourt or somebody else's. The registration lands in the compliance column. The margin damage lands in yours, one quarter later, recorded as weak used performance rather than as the cost of a compliance decision made above you.
EV owners are the most dealer-loyal customers in the market. The network is busy handing them away.The finding that inverts the aftersales argument
The scheduled visit really does halve. Volkswagen's all-electric ID family has no mileage interval at all — an inspection service every two years. BYD runs every two years or 20,000 miles. Nissan specifies the Leaf annually or every 18,000. Against a petrol norm of twelve months or 12,000 miles, and diesels that often need an interim at six months on short urban work.
Over a five year ownership cycle, that is roughly five scheduled visits becoming two or three. The content of each one thins as well: minor service parts around 18% lower than the petrol equivalent and fluids around 70% lower; on major services, parts and fluids roughly 58% and 63% lower. The net measured effect is an annual workshop revenue shortfall of about £175 per EV.
Weight drives tyre and suspension wear earlier than the ICE equivalent, which moves those items from an afterthought to a genuine revenue line. Brake fluid, cabin filters, coolant and the 12V battery all remain. And EVs account for around one in five recalls despite being roughly one in eighteen vehicles on the road — which is a manufacturer-funded reason to contact a customer, and one most networks treat as an administrative burden rather than the retention opportunity it is.
Cox Automotive's fixed operations work found that EV owners are the most dealer-reliant group in the market — 67% of their service visits go to a franchised dealer, against 28% for ICE owners and 50% for hybrids. They also spend the most per visit, and well over half use the service visit to explore trade-in value, with around one in five going on to trade in and buy after meeting a salesperson while their car was in. Fewer visits, from a customer far less likely to drift to the independent sector and far more likely to buy their next car from you. That is not a shrinking aftersales business. It is a concentrated one — and every point above about battery centres and referred work is the network giving that concentration away.
At the front of the market, yes. EVs under twelve months old recovered from around 52% to 56% of original cost new across 2025, and three year depreciation now sits at roughly 38–42% against 35–40% for an equivalent petrol car. That gap was fourteen points not long ago. It has narrowed considerably, and on the best-retained models it has effectively closed.
Across the broader market, no. Used EV values are still down around 10% year on year as ex-fleet and salary sacrifice volume returns, and roughly two thirds of leasing and rental firms expect further falls through the rest of this year. The consensus view puts genuine stabilisation at late 2026 or early 2027 — which, not coincidentally, is when the mandate review lands.
And that is the honest answer to whether the losses have stopped: the single biggest identified risk to future EV residual values is the mandate itself, because the discounting used to hit the target is what drags the used values underneath it. Soften the target and you soften the discounting. Which makes your used EV book a direct, unhedged bet on a policy decision that has been rewritten roughly every six months for three years.
The trap in a moving target is waiting for it to stop moving. It won't, in time to be useful. So the practical discipline is to separate the decisions that depend on the number from the decisions that don't — and to get on with the second group.
None of those six requires knowing whether 2030 means 50% or 80%. All six are being deferred in a great many businesses precisely because the number isn't known — which is the wrong reading of the uncertainty. The policy is what is uncertain. The vehicles are already here.
There is a legitimate grievance here. The network has been asked to invest against a target that has been rewritten repeatedly, by people who carry none of the cost when it moves again, and the frustration in the trade is earned rather than manufactured.
But the grievance and the operational decision are separate things, and running them together is expensive. Every item on the list above is true at any mandate level, is funded by work already sitting in the parc, and is being deferred while the network waits for a number that will not arrive before early 2027 — by which time the customers concerned will have been someone else's for two years.
