Switching EV Salary Sacrifice Provider: What Happens to Your Existing Cars

Every comparison of EV salary sacrifice providers ends at the same place: a table showing who offers what, and a recommendation. What almost none of them answer is the question that actually stops employers from moving. If we already have 40 people in cars through our current provider, what happens to those 40 cars?
The short answer is that nothing happens to them. An electric car salary sacrifice scheme is a collection of individual lease agreements, each with its own end date, sitting on top of a services agreement between the employer and the provider. Changing provider changes where new orders go. It does not, by default, touch a single car already on the road. Understanding that distinction is what turns a switch from a fleet project into an administrative one, and it is worth understanding before you compare providers on employer protection and pricing.
Why switching feels riskier than it is
The fear is usually a version of the same scenario: the employer signs with a new provider, the old provider objects, and 40 employees are left mid-lease with no idea who to call about a puncture or a charging card. That scenario does not happen, because the outgoing provider's obligations to those employees are contractual and unaffected by anything the employer signs elsewhere.
What does need managing is the overlap. For a period, two providers will be sending payroll instructions, two sets of invoices will arrive, and two support routes will be live. The tax treatment itself does not change with the provider, because salary sacrifice is a mechanism defined by HMRC rather than by any scheme operator. That overlap is entirely manageable, but it needs to be planned rather than discovered in the first payroll run after go-live. Employers who have already worked through the operational detail of setting up a scheme from scratch will recognise most of the steps; migration simply adds a legacy cohort to the same process.
The four-phase approach to phasing out an existing scheme
The cleanest migration does not attempt to move anything. It freezes the old scheme and lets it empty itself.
| Phase | What happens |
|---|---|
| 1. Freeze new orders | Stop taking new orders on the old scheme from an agreed date. Communicate this to HR and employees. Nobody already in a car is affected. |
| 2. Launch the new scheme in parallel | Sign the incoming provider's services agreement and begin onboarding. Every order from this date forward goes through the new scheme. |
| 3. Natural wind-down | Existing cars run to their contracted lease or subscription end. As each car goes back, the re-order is placed through the new provider and the old scheme shrinks. |
| 4. Old scheme closes | Once the last legacy car has been returned and all invoices reconciled, the old agreement can be formally terminated. |
The length of phase three is set by your longest remaining lease, not by anything the new provider does. A scheme with a mix of 24, 36 and 48-month agreements will take up to four years to empty completely, though the bulk of the fleet usually turns over much faster. Because EV salary sacrifice tax treatment is secured to 2030, a wind-down running across several tax years carries no policy risk for either cohort. Because early termination charges are calculated from the remaining rentals less the car's market value, forcing legacy cars back early is almost always the most expensive way to migrate. Letting them run their term costs nothing extra.
Novation: when a lease actually has to transfer
Novation is the legal process of transferring a lease from one employer to another. It is a three-party agreement, and it is far less commonly needed than employers assume. Critically, a company can sign up with a new provider without any novation taking place at all.
Novation is required when the employing entity on the agreement changes. That covers three situations in practice. The first is where an employee leaves and joins a new employer who wants to take the car with them; the lease transfers, the new employer takes over the payments, and a fresh salary sacrifice agreement is put in place with the employee. The second is where an employee resigns or is made redundant and no internal colleague wants the car, so it is marketed for a period and picked up by a driver at a different company. The third is a dismissal followed by the same outcome, with a replacement driver at a different employer. These are the same leaver scenarios that drive early termination decisions generally, and novation is simply the outcome where a car finds a home at another company rather than being returned.
Novation is not required when the employer stays the same, even if a good deal else changes. An employee moving between companies inside the same group is an intra-group transfer: the original company keeps paying the lessor, the new company provides the car and takes the salary sacrifice deduction, then reimburses the original entity. An internal colleague taking over a leaver's car is a straightforward internal transfer. An employee switching product type, from subscription to lease for example, is a product change rather than a company change, so new salary sacrifice documents are issued but the lease itself is untouched. The rules that apply when an employee's circumstances change mid-term matter far more to most employers than novation ever will.
Can a new provider take over the management of existing leases?
Sometimes, yes. Where cars already sit on certain leasing companies' frameworks, a novation can bring those leases under the new provider's management rather than waiting for them to expire. This is the exception rather than the default, and it depends entirely on the lessor's own policy.
| Lessor | Typical lead time | What the process involves |
|---|---|---|
| Alphabet | 4-6 weeks | Deed of Novation, Master Hire Agreement signed, plus a credit check on the incoming employer. |
| ALD / Ayvens | Around 4 weeks | Authority to Act forms, a new Direct Debit mandate and a Novation Account Form. |
| Lex Autolease | Varies | Managed directly through Lex's dedicated transfer process by the incoming provider. |
| Novuna | Varies | Coordinated directly with Novuna by the incoming provider's returns team. |
| Arval | Varies | Novation request form submitted for approval or decline; once approved, a transfer agreement and Direct Debit mandate are issued for signature. |
Two caveats matter. Novation requires consent from all three parties, and not every lessor permits it in every circumstance, so the answer is always case by case rather than guaranteed. Per-vehicle administration fees usually apply and vary by lessor, typically charged at a higher rate for the first vehicle and a nominal amount for each one after. Any credible provider will confirm both the appetite and the cost before you commit to anything.
Because novation adds cost, lead time and a credit check, the phased wind-down is the right default. Novation is the tool for the minority of cases where an employer genuinely needs consolidated management sooner, most often larger fleets where split reporting across two providers creates more work than the fees.
Running two schemes at the same time
During migration there will almost certainly be a period where some employees are on the old scheme and everyone new is on the incoming one. This is normal. Three areas need briefing in advance.
Payroll
Two sets of salary sacrifice deductions will run concurrently, and each scheme has its own payroll instruction format. Brief your payroll team before launch rather than after, confirm which report covers which employees, and agree a naming convention so the two files are never confused. A good provider will supply a monthly payroll report with a clearly structured tab listing every employee's gross and net deductions, and will join a call with your payroll team to walk through the format. Getting this wrong is one of the more common and more expensive scheme administration mistakes, because a missed deduction has to be corrected retrospectively.
Invoices and direct debits
Expect invoices from two directions. The outgoing provider continues to bill as normal for every legacy car, and queries on those contracts go to that provider's account team since a new provider cannot intervene in a third-party contract. Alongside that, the incoming provider raises its administration fee at the start of each month, and each lessor or subscription partner invoices separately for the cars it funds. In practice that means at least two new direct debits for the incoming scheme, one for the administration fee and at least one per funder, running alongside every existing mandate for the old provider. If you also add salary sacrifice on charging through The Charge Scheme, that appears as a separate line item and is cost-neutral, funded by the employer's National Insurance savings at the 15% Class 1 rate.
Finance needs this picture before the first month, not during it.
Employee communications
Clarity is what prevents the support queue filling up. The rule employees need is a single sentence: if you already have a car, nothing changes; if you order from the go-live date, you use the new scheme. Say it once, clearly, and repeat it in the launch email.
A message along these lines works:
From [date], all new electric car orders are placed through [new provider]. If you already have a car through [old provider], nothing changes. Your car, your payments and your support contact stay the same. When your lease ends, your renewal will come through [new provider]. Any questions, contact HR or visit the employee portal.
The second sentence is the one that matters. Most employee anxiety during a provider change comes from assuming their own car is in play. Employees who want the detail behind the change will find the common questions on salary sacrifice answered in one place, and those weighing up a first order can see what the savings look like against their own tax band.
P46(Car), P11D and the April 2027 payrolling deadline
Reporting responsibility splits during the parallel period, and this is the detail most often missed. The outgoing provider handles P46(Car) and P11D reporting for legacy cars; the incoming provider handles new cars. Confirm in writing with your old provider who owns legacy car reporting, because an assumption here produces a gap that only surfaces at year end.
A good provider will supply draft, pre-populated P46 forms monthly and draft P11D forms at year end for every car under its own scheme. With pure electric cars taxed at 4% of list price for the 2026/27 tax year, the Benefit-in-Kind figures involved are modest, but the filing obligation is the same regardless of the amount.
The timing matters for a second reason. From April 2027, all benefits-in-kind must be payrolled through Full Payment Submission. If your business is not already payrolling benefits, a provider change is a natural moment to prepare for that shift rather than treating it as a separate project later.
Migration checklist
| Stage | Actions |
|---|---|
| Pre-migration | Confirm the notice period with your existing provider. Identify every employee currently in a car and their lease-end dates. Confirm which cars, if any, can be novated. Identify eligible employees not yet in a car as the first cohort for the new scheme. Assign a scheme coordinator in HR or operations. Brief finance on incoming direct debits and the payroll report format. Sign the new services agreement. |
| Onboarding (weeks 1-3) | Submit director details for the credit application. Sign Master Hire Agreements with the funders. Set up the direct debit. Provide the employee email list. Confirm employer portal access for the scheme coordinator and add further admins as needed. Complete the HR and finance webinar. |
| Launch | Send the internal announcement from the employer. Trigger the provider's employee launch email. Schedule and run the employee webinars. Make the quote tool live. Send a separate note to existing car holders confirming they stay on the old scheme until lease end. |
| Ongoing wind-down | Track remaining lease-end dates on the old scheme. Download and action monthly reports. Re-order through the new provider as legacy leases end. Formally close the old scheme once the last car is returned. Confirm final P11D and payrolling obligations with the outgoing provider. |
Most of the work sits in the pre-migration row, and specifically in building an accurate list of who is in a car and when each agreement ends. Employers who start there find the rest follows a familiar path, much the same as a larger enterprise scheme rollout. From the launch row onwards the sequence is identical to the standard scheme implementation checklist, with the single addition of the note to existing car holders.
What to check before committing to a new provider
If you are going through the effort of a migration, the new scheme should be measurably better than the one it replaces, not merely cheaper on a headline quote.
Employer protection is the first test, and the one where providers differ most. Many schemes impose a three-month exclusion period before cover begins, which leaves the employer carrying early termination costs on any car ordered by someone who resigns or is made redundant in that window. Complete Employer Protection from day one removes that gap entirely, with no excess and no exclusion period, covering resignation, redundancy, dismissal, long-term illness, parental leave and damage. Given that termination exposure on a single car can run into five figures, this is not a minor contractual detail. Employee-side cover has moved on as well, and the last structural barriers to EV salary sacrifice are worth reviewing against whatever your outgoing scheme offered.
Funding structure is the second. A single-funder provider quotes whatever its one leasing partner offers. A multi-funder pricing engine puts several UK leasing partners in competition on every quote, which is where genuine price differences appear over a fleet of any size. Ask how many funders are in the panel before comparing monthly figures, then check the quote against the range of electric cars available through salary sacrifice rather than a single headline model.
Vehicle availability is the third. New and used electric cars through salary sacrifice widen the range considerably, and used stock can be delivered in around 14 days rather than the lead times new build slots often carry.
Finally, treat headline savings claims sceptically. Employee savings through salary sacrifice run at 20-50%, from 20% for a basic-rate taxpayer to around 50% for an additional-rate taxpayer earning above £125,140. Any provider advertising 60% is folding the employer's National Insurance savings into the employee's headline number, which is not a saving the employee ever sees. The independent comparison of leading UK providers is a useful cross-check, as are the direct comparisons against Tusker and Octopus.
Ready to switch?
Switching EV salary sacrifice provider is a new-orders decision, not a fleet transfer. Employees already in cars keep the car, the payments and the support contact they have, and their agreements run to their natural end while every new order goes through the incoming scheme. Novation exists for the narrow set of cases where the employing entity itself changes, and it is optional rather than a precondition of moving. What genuinely needs planning is the parallel period: two payroll files, two sets of invoices, and a clear split of P46(Car) and P11D responsibility, all of which a competent provider will map out with your HR and finance teams before go-live.
The Electric Car Scheme runs this process for employers including Holland & Barrett, Leeds Bradford Airport and TopCashback, at £0 set-up cost, and was named EV Salary Sacrifice Provider of the Year 2026 by SME News. If you are weighing up a move, the practical starting point is a list of your current lease-end dates and a quote for the employees who are not yet in a car.
