TUPE Redundancy Calculator: What Transfers Do and Do Not Change

If you are searching for a TUPE redundancy calculator, the first thing to know is that TUPE is not a separate redundancy formula. In most cases, the statutory redundancy math stays the same. What changes is the employment history that feeds into the calculation, especially your continuity of service after a transfer.

That means a calculator can still help, but only after you confirm whether TUPE protection applies and whether your old service should count with the new employer.

What TUPE usually changes

TUPE is short for the Transfer of Undertakings (Protection of Employment) Regulations. In practical terms, it can move employees from one employer to another when a business or service transfers. Where TUPE applies, the new employer usually takes on the employment relationship as it stands, including continuity of service.

That matters because statutory redundancy pay depends heavily on:

• continuous service
• age during each full year of service
• weekly pay, subject to the statutory cap

If the new employer wrongly treats you as a brand-new starter after transfer, the redundancy figure can come out much lower than it should.

Can you be made redundant after a TUPE transfer?

Sometimes yes, but the reason matters. A transfer by itself should not usually be the sole reason for dismissal. Employers often talk about an economic, technical or organisational reason involving changes in the workforce, usually shortened to an ETO reason.

In plain English, a redundancy after TUPE is more likely to be defensible where there is a genuine need for fewer employees or a real reorganisation, rather than a simple desire to remove transferred staff.

How a TUPE redundancy calculation usually works

Once you have confirmed that TUPE transferred your service, the statutory redundancy calculation usually goes back to the normal rules on GOV.UK:

Factor	Statutory approach
Service	Up to 20 years, including transferred service where continuity is preserved
Age band	0.5 week, 1 week, or 1.5 weeks depending on age during each year
Weekly pay	Average weekly pay over the 12 weeks before notice, capped by law

If dismissal is on or after 6 April 2026, the statutory weekly cap shown by GOV.UK is GBP751, with a maximum statutory redundancy payment of GBP22,530.

Use the Redundancy Pay Calculator once you know the correct service start date and weekly pay figure.

What often goes wrong after a transfer

The most common TUPE redundancy mistakes are not about the calculator itself. They are about the input data:

• pre-transfer service is ignored
• the wrong start date is used
• the employer mixes up contractual and statutory redundancy
• weekly pay is estimated loosely instead of averaged properly

You should also keep an eye on whether the employer is using redundancy as a label for what is really a transfer-related dismissal without a genuine workforce reduction.

Worked example

Suppose an employee worked 5 years for Employer A, then transferred under TUPE and worked a further 3 years for Employer B before being made redundant. If TUPE preserved continuity, the statutory redundancy calculation would usually be based on 8 years of service, not 3.

That one point can make a big difference to the result. It is why a “TUPE redundancy calculator” is really a redundancy calculator plus a service-continuity check.

What documents should you check?

Before accepting the employer’s figure, check:

• your original start date
• the TUPE transfer date
• any employee liability information or transfer letters
• the redundancy letter
• the written breakdown of statutory redundancy pay

An employer should be able to explain the service date and weekly pay figure used. If they cannot, that is a sign to slow down and verify the numbers.

Frequently Asked Questions

Does TUPE reset redundancy pay?

Usually no. If TUPE applies, continuity of employment normally transfers to the new employer. That means earlier service should often still count when statutory redundancy pay is worked out.

Can I use a normal redundancy calculator after TUPE?

Yes, but only after confirming the right service history. The formula is usually the normal statutory redundancy formula. The key question is whether transferred service must be included.

Does TUPE guarantee I cannot be made redundant?

No. Redundancy can still happen after a transfer, but the employer should usually have a genuine redundancy or other lawful workforce reason rather than dismissing because of the transfer itself.

What if my new employer only counts service after transfer?

That may be wrong if TUPE preserved continuity. Ask for a written breakdown and compare it with your transfer paperwork and original employment dates.

The Bottom Line

A TUPE redundancy calculator is really about two steps: confirm whether TUPE preserved your continuity of service, then apply the ordinary statutory redundancy rules. If the service date is wrong, the result will be wrong too. Use the Redundancy Pay Calculator once you have checked the transfer paperwork and the dismissal date.

Step-by-step checklist

1

Check whether service transferred under TUPE

If TUPE applied, continuity of employment usually transfers too, which can matter a lot for redundancy entitlement.

2

Separate TUPE issues from redundancy math

First confirm whether the transfer was valid, then calculate statutory redundancy using age, service, and capped weekly pay.

3

Compare the transfer records with the employer's calculation

Ask for the service date and weekly pay figure used so you can spot whether pre-transfer service was ignored.
