Switching EOR providers is one of those topics that barely gets written about — because EOR providers have no interest in helping you do it, and because most content in this space is aimed at businesses picking an EOR for the first time, not businesses that already have one and want out.
But the situation is common. You signed with a provider that made sense at the time. The service turned out to be mediocre. The fee went up at renewal. Or you’ve grown, and what worked for three employees genuinely doesn’t work for fifteen.
Whatever the reason: switching is doable. It’s less complicated than it sounds, and there are a handful of things worth knowing before you start.
Check your current contract!
Before you contact a single alternative provider, read your existing MSA — specifically the termination and notice clauses.
Most EOR contracts require 30 to 90 days’ notice to end the service. Some include minimum commitment periods of three to six months. A small number include exit fees, sometimes dressed up as “transition support fees” or “final service charges.” These are contractual facts, not negotiating points.
Your notice period determines your timeline. If your contract requires 60 days’ notice and you want to switch in six weeks, you’ve already missed the window — or you need to serve notice immediately while you’re still selecting your new provider. That’s an uncomfortable position to be in.
Also check for auto-renewal clauses. Many EOR contracts renew automatically at the end of each term. If you miss the renewal window — typically 30 to 60 days before the contract anniversary — you can find yourself locked into another full term before you’ve had a chance to act.
Recommended Employer of Record
What you’re actually transferring
When you switch EOR providers, what moves is the legal employment relationship for each affected employee. The new EOR becomes the legal employer; the old EOR’s name comes off the contract.
In UK employment law, this is almost certainly a TUPE transfer — Transfer of Undertakings, Protection of Employment. Under TUPE, employees’ terms and conditions transfer intact to the new employer. Same salary, same contractual benefits, same continuous service period, same holiday entitlement. You can’t use the provider switch as a reason to change anything.
In practice, EOR-to-EOR TUPE transfers are usually straightforward — everything stays the same, only the employer’s name changes. But the process still needs to be handled correctly. That means giving employees written notice of the transfer, telling them who the new employer will be, and completing any required consultation. If you have more than a handful of employees transferring, 30 minutes with an employment lawyer to check your specific obligations costs less than getting it wrong.
A realistic timeline
A typical switch takes six to ten weeks from decision to first payroll running with the new provider. The shape looks roughly like this:
Weeks 1–2: Select your new provider. Get quotes, ask for fully loaded cost illustrations (not just the service fee), and ask specifically how they handle TUPE transfers from another EOR. A provider that has done this before will have a clear process. One that hasn’t will be less reassuring.
Weeks 2–3: Serve notice on your current provider. Once you’ve confirmed your new EOR and you know your contractual timeline, serve written notice on your current provider per the MSA. Get confirmation of receipt in writing.
Weeks 3–5: New provider setup. The incoming EOR prepares for your employees — contracting framework, payroll configuration, pension scheme, HR platform access. Most of this happens on their side.
Weeks 5–6: Notify employees. Inform employees of the transfer. Under TUPE, they have the right to know who the new employer is, when the transfer takes effect, and whether any changes to their employment are planned (there shouldn’t be). Keep it simple and direct — most employees, given clear communication, won’t find this alarming.
Weeks 6–8: New contracts issued. The new EOR issues employment contracts to each transferring employee. The terms should be identical to their current contracts. Employees sign and return.
Weeks 8–10: First payroll with the new provider. The new EOR runs payroll for the first time. The outgoing EOR processes the final payroll under its system and issues P45s.
The timing of the payroll handover needs careful coordination. No employee should end up in a gap — paid by nobody — or double-registered on two PAYE schemes simultaneously. A competent new provider will manage this coordination with the outgoing EOR directly. Ask them how they handle it before you commit.
What tends to go wrong
Pension continuity. Employees enrolled in the outgoing EOR’s pension scheme need their contributions to transfer to the new EOR’s scheme. Confirm that the new EOR’s pension is a qualifying auto-enrolment scheme, and that the handover process maintains contribution continuity without a break. A gap in pension contributions is a compliance problem for you, not just an administrative one.
Holiday accrual records. Make sure the incoming EOR has accurate figures for each employee’s accrued holiday and any carried-over entitlement at the date of transfer. Errors here tend to generate grievances.
Tax codes. Employees’ tax codes should follow them, but in practice this sometimes requires HMRC notification from both the old and new EOR, and payroll errors in the first month under the new provider are not unusual. Have a process to spot and correct them quickly.
Employee reaction. Most employees will be fine if you handle the communication well. “Your employment is transferring to a new payroll company — your pay, terms, and job stay exactly the same” is a reassuring message when delivered clearly. It becomes less reassuring when employees find out indirectly, hear it third-hand, or are left to wonder what it means for their pension.
Data transfer and GDPR. Your employees’ personal data — held by the outgoing EOR — needs to move to the new one. Both providers have obligations under UK GDPR. Confirm that the transfer is handled compliantly and that the outgoing EOR deletes the data once the transition is complete. Get written confirmation.
Is it worth the effort?
Usually, yes — when one of three things is true.
Cost is the clearest case. If you’ve found a provider that’s materially cheaper on a fully loaded basis, and the transition costs (any exit fees, management time, potential legal advice) don’t wipe out the saving, the maths tends to support switching. A 15–20% reduction in EOR costs for a business with ten employees can represent meaningful annual savings.
Service quality is the less quantifiable but often more compelling reason. Persistent payroll errors, slow support responses, and a poor HR platform don’t fix themselves over time. If your current provider is consistently letting you down, switching to a better-run operation is worth the short-term disruption.
Growth is the third. A provider that was fine at three employees may lack the account management depth or platform capability to serve you well at fifteen or twenty. Switching at a natural growth milestone — before you’re under pressure — is considerably easier than switching during a hiring sprint when you have neither the time nor the bandwidth to manage a transition properly.
The honest counter-argument is transition risk: the chance of a payroll error, an unsettled employee, or a TUPE misstep. That risk is real. It’s also manageable — most EOR transitions, handled carefully, go smoothly. The businesses that struggle tend to be the ones who rushed the process or chose a new provider without checking whether they’d done this kind of transfer before.
