How To Transfer Employees To Another Company Payroll In The UK

If you’re running a small business, there are plenty of practical reasons you might be transferring employees from one company to another payroll - a restructure, a group reorganisation, a change in trading entity, acquiring a business, or simply moving staff from one part of the business to another.

But while it can feel like an “admin” task, moving someone onto a new payroll is rarely just a payroll exercise. It can trigger employment law obligations, tax and reporting duties, pension requirements, and data protection considerations.

The good news is: with a clear plan, you can transfer staff smoothly and keep your business protected from day one.

What Does “Transferring Employees From One Company To Another Payroll” Actually Mean?

In practice, transferring employees from one company to another payroll usually means one of two things:

• The employing entity is changing (eg employees move from Company A to Company B, with a new employer taking on legal responsibility for wages, tax, holiday, and employment rights).
• The payroll provider/processing is changing (eg you’ve switched payroll software or outsourced payroll, but the employer remains the same legal entity).

Those two scenarios look similar from a payslip perspective, but legally they’re very different. If the employer is changing, you’ll usually need to consider:

• whether the transfer is covered by TUPE (Transfer of Undertakings (Protection of Employment) Regulations 2006);
• whether the move is being handled as a dismissal and re-engagement (which can create unfair dismissal risk if mishandled);
• whether you need consultation and employee communications;
• how you will handle payroll setup, HMRC reporting, and pension auto-enrolment.

If you’re not sure which scenario you’re in, start with this: who will be legally responsible for employing the employee and paying them after the change? That’s the entity that matters.

Is It A TUPE Transfer Or A “New Employment” Situation?

For many small businesses, the key legal question is whether you’re moving staff as part of a business transfer covered by TUPE.

TUPE may apply where there is:

• a business transfer (eg one business, or part of a business, moves to a new owner); or
• a service provision change (eg outsourcing, insourcing, or a change of contractor - with some important conditions).

If TUPE applies, employment transfers by operation of law to the new employer and employees’ continuity of employment is preserved. However, there are important edge cases (for example, what happens if an employee objects to transferring, or if dismissals occur for reasons connected with the transfer).

If TUPE doesn’t apply, you may be looking at a different process (for example, ending employment with Company A and offering a new contract with Company B). That can still be done - but it needs careful handling to avoid claims, especially where employees don’t agree to the change.

It can get tricky because group restructures and payroll moves can sit in a grey area. That’s why many employers start with a TUPE-style risk check and a clear paper trail. A practical resource to keep you organised is a TUPE transfer checklist so you don’t miss the operational steps alongside the legal ones.

Why This Matters For Small Businesses

If TUPE applies and you treat it like a simple payroll change, you can accidentally create:

• unfair dismissal risk (eg dismissing and rehiring when employment should have transferred automatically);
• breach of contract risk (eg attempting to change terms because “the payroll is different now”);
• collective consultation problems (where consultation duties are triggered);
• employee relations issues if communication is unclear or late.

On the other hand, if TUPE doesn’t apply and you assume it does, you might miss the steps you actually need (like properly issuing new contracts and documenting consent).

Step-By-Step: Legal Process For Moving Employees To Another Payroll (When The Employer Changes)

If the change is genuinely moving employees from one employing entity to another, here’s a practical step-by-step approach that usually works well for small businesses.

1) Confirm The Commercial Reason And The “Transfer Scenario”

Start by documenting:

• which entity employs staff today (Company A);
• which entity will employ staff going forward (Company B);
• what is transferring (a whole business, a department, a contract, a function);
• the proposed transfer date;
• whether there are any planned changes to roles, location, hours, or reporting lines.

This isn’t just paperwork - it’s your foundation for assessing whether TUPE is in play and what communications you need.

2) Do A TUPE Assessment (And Get Advice If It’s Not Obvious)

Where there is any doubt, it’s usually worth getting tailored advice early. TUPE assessments depend heavily on facts (what’s transferring, how the work is organised, whether there is an “organised grouping of employees”, and whether the activities remain fundamentally the same).

If TUPE applies, you’ll typically need to plan for:

• informing and (where required) consulting with affected employees or their representatives (including, in some cases, electing representatives);
• the outgoing employer providing Employee Liability Information to the incoming employer;
• honouring continuity of employment and existing contractual terms (subject to limited exceptions).

3) Plan Your Communication With Staff (And Keep It Simple)

Even when employees are staying in the same workplace doing the same job, “your employer is changing” can feel unsettling. Your messaging should clearly cover:

• what is changing (the employing entity/payroll);
• what isn’t changing (role, manager, pay date, benefits - if true);
• what happens to continuity of service (particularly important for rights like unfair dismissal and redundancy pay);
• what employees need to do (eg sign a new contract, complete payroll forms, confirm bank details).

In many cases, a short letter/email plus a Q&A is enough. The key is that it’s accurate and consistent with your legal position (TUPE vs new employment).

4) Check Whether Any Terms Are Changing (And Be Careful)

One of the most common mistakes when transferring employees from one company to another payroll is assuming you can “tidy up” old terms at the same time (eg updating overtime, removing allowances, changing commission rules, or rewriting notice provisions).

If TUPE applies, changes connected to the transfer are heavily restricted and can be void unless a specific exception applies. Even if TUPE doesn’t apply, changing terms without agreement can still create breach of contract and constructive dismissal risk.

If you need to update contracts, do it in a structured way and document the variation properly. In many cases, it’s safer to keep terms the same on day one, and review changes later once the transfer is settled.

5) Put The Right Employment Paperwork In Place

Your documents will depend on whether TUPE applies and what exactly is changing, but commonly you’ll need:

• an updated Employment Contract (or confirmation that existing terms transfer);
• updated policies/handbook references (if Company B has different policies);
• variation letters, if any contractual changes are agreed;
• confirmation of continuous service date (where relevant).

It’s also a good time to check whether your key clauses still protect you (confidentiality, IP ownership, post-termination restraints, and notice provisions) - especially if the “new employer” is a different company with different risk exposure.

6) Decide What Happens If An Employee Doesn’t Agree

Sometimes employees will push back - not necessarily because they’re being difficult, but because they’re worried about job security, benefits, or service continuity.

How you handle this depends on the legal basis for the transfer. For example:

• If TUPE applies, employees typically transfer automatically, but an employee may object to transferring (which can bring their employment to an end without it necessarily being a dismissal). There are also specific rules and risks around any dismissals connected with the transfer.
• If TUPE doesn’t apply, you may need the employee to accept a new contract with Company B. If they refuse, you could be facing a termination/rehire scenario, which needs careful risk management.

If you’re at this stage, it’s worth getting advice early - small process errors can cause outsized legal risk. If the change could lead to roles being removed or duplicated, redundancy advice can also be relevant depending on your restructure.

Payroll, HMRC, And Pension Steps You Can’t Skip

Once you’re confident about the employment law pathway, you’ll also need to implement the payroll change correctly. When moving employees to a new employing entity and payroll, payroll mistakes can create immediate issues like late pay, incorrect tax codes, or broken pension contributions - which quickly damages trust.

Note: The payroll, HMRC, and pensions points below are general guidance only and aren’t tax, financial, or accounting advice. Your accountant, payroll provider, or pensions adviser can help you apply the rules to your setup.

PAYE And HMRC Reporting

If Company B is the new employer, it generally needs:

• a PAYE scheme (if it doesn’t already have one);
• to set employees up as new starters for payroll purposes (even if they’re “the same employees” operationally);
• to gather the right starter information (P45 where applicable, or starter checklist details);
• to ensure Real Time Information (RTI) submissions are accurate from the first payment.

Also consider timing: if the transfer date is mid-pay period, you’ll need to decide how to split pay and deductions so there’s a clean handover.

Holiday And Absence Records

If continuity is preserved (as is commonly the case under TUPE), you’ll need to ensure that records transfer properly, including:

• holiday taken and remaining entitlement;
• sickness records and any ongoing sick pay arrangements;
• family leave records (maternity/paternity/shared parental leave).

This matters because even if you “start fresh” on payroll, the employee’s underlying statutory rights don’t necessarily reset.

Pensions And Auto-Enrolment

Transferring employees can also affect workplace pension duties. Depending on how the transfer is structured, Company B may need to:

• review its auto-enrolment duties for the transferred workforce and make sure contributions continue where required;
• check what pension obligations carry over under TUPE (note that occupational pension rights are treated differently to most other contractual terms, and special rules can apply);
• coordinate scheme participation and required employee communications.

Pensions can be a hidden tripwire in transfers, so it’s worth involving your payroll provider and pension provider early.

Data Protection And Confidentiality: Don’t Accidentally Create A GDPR Problem

To move employees to a new employer and payroll, you’ll be sharing and processing personal data - names, addresses, bank details, salary, NI numbers, performance notes, sickness absence, and potentially special category data.

That triggers UK GDPR and the Data Protection Act 2018 considerations. For small businesses, the practical takeaways are:

• only share what’s necessary for the transfer;
• keep the data secure during transfer (access controls, encryption, secure file sharing);
• be clear about roles: who is the controller, and who is a processor (especially if you outsource payroll);
• provide or update the appropriate employee privacy information (often via an employee privacy notice) so staff understand how their data is used.

If you use third-party providers, it’s important your contractual protections are right. For example, a Data Processing Agreement is often essential where a supplier is processing employee data on your behalf.

Key Contracts And Documents To Prepare Before You Transfer

When you’re transferring employees from one company to another payroll, the right paperwork helps you avoid misunderstandings and gives you a clear record of what was agreed (and when).

Depending on your setup, consider whether you need the following:

Employment Contracts And Variations

• If you’re issuing new contracts under Company B, ensure the Employment Contract reflects the correct employer name, job title, pay, place of work, notice, and key protections.
• If you’re keeping existing terms (eg TUPE transfer), have written confirmation to employees explaining the transfer and confirming continuity where appropriate.

Company Resolutions And Signing Authority

If the restructure involves multiple companies in a group, make sure the right people are signing the right documents for the right entity. Problems here often show up later in disputes (“was that contract even valid?”).

If you’re unsure about who can sign what (and how), getting your processes right around signing authority can save you time and headaches.

Settlement Or Exit Documents (If Needed)

In a perfect world, a transfer is straightforward and nobody leaves. But in real life, some employees may decide the change isn’t for them, or your restructure may mean some roles can’t continue.

If exits are on the table, you’ll want to handle them carefully and legally. Documents like a Deed of Settlement may be relevant in certain situations - but only where it fits the facts and you’ve followed a fair process.

Policies And Handbooks

Company B should have fit-for-purpose workplace policies (especially if it will now employ staff directly). If you’re rolling out new IT systems or tighter controls after the transfer, you may also want to align expectations with an Acceptable Use Policy.

Policies won’t fix a broken transfer process - but they do help set standards and reduce disputes once the transfer is complete.

Key Takeaways

• Transferring employees from one company to another payroll is often more than an admin change - if the employing entity changes, you may be dealing with TUPE, continuity of employment, and information/consultation duties.
• Start by confirming who the legal employer is before and after the move; this determines whether it’s a payroll provider change or a true employment transfer.
• If TUPE applies, employees usually transfer by operation of law and their continuity and key terms are protected, but there are important edge cases (including objections and transfer-related dismissals) that need careful handling.
• Plan your employee communications early and keep them consistent, clear, and accurate to reduce confusion and pushback.
• Don’t forget the operational legals: PAYE/RTI reporting, holiday records, and pension duties need a clean handover to avoid pay and compliance issues.
• Because you’ll be sharing employee information, build in UK GDPR safeguards and ensure appropriate contracts are in place with any payroll or HR providers.
• Getting the right contracts and documents in place upfront is one of the simplest ways to protect your business during a restructure.
