Navigating the world of employment often leads to questions about remuneration, and a common query revolves around the timing of pay rises. While many employees anticipate annual increments, the reality is that pay increases can be triggered by a variety of circumstances. Understanding these triggers is crucial for ensuring you receive the compensation you are rightfully due. This article delves into the key factors that can initiate a pay rise, focusing on specific situations that might affect your earnings, including TUPE transfers, changes to the National Minimum Wage, and the fundamental principle of equal pay.

Pay Rises and TUPE Transfers: A Seamless Transition
The Transfer of Undertakings (Protection of Employment) regulations, commonly known as TUPE, are designed to safeguard employees' rights when a business or part of a business changes hands. This can occur when an organisation is acquired, or when a contract for services, such as office cleaning or IT support, is transferred to a new provider. In essence, TUPE ensures that your employment contract, along with all its existing terms and conditions, automatically transfers to the new employer on the date of the transfer. This means you don't start a new contract; your existing one simply continues under the new ownership.
A critical aspect of TUPE for pay rises is the protection of contractual entitlements. If your current employment contract includes a clause that guarantees a pay rise, whether it's an annual review, a performance-related increase, or a scheduled increment, this entitlement automatically transfers to your new employer. The new employer is bound by these existing terms. They can only alter your contract, including the terms related to pay rises, if specific, legally defined conditions are met. These conditions often involve consultation with employees or their representatives, or in some limited circumstances, if the changes are for an "economic, technical or organisational reason entailing changes in the workforce". It's vital to be aware of your contractual rights during such a transfer to ensure your pay progression remains on track.
The National Minimum Wage: Ensuring Fair Earnings
For employees paid at or around the National Minimum Wage (NMW), changes in government-set rates can directly lead to a pay rise. The NMW rates are typically reviewed and updated annually, usually in April. If you are paid the NMW, you are entitled to an increase in your pay if:
- The government announces an increase in the statutory rates.
- You reach a certain age threshold. For example, turning 18 or 21 can mean you become eligible for a higher NMW rate, depending on the specific rates applicable to different age groups.
- You are an apprentice. If you are an apprentice and turn 19, or if you are already 19 and complete the first year of your apprenticeship, you may be entitled to an increase in the apprentice rate of the NMW.
It's important to note that the higher rate of pay doesn't always apply immediately from the exact date of your birthday or the government's announcement. The effective date for the pay increase is typically from the next pay reference period after the change. A pay reference period is the period of time covered by a single wage payment, such as a week or a month. This means there might be a slight delay between the trigger event and the actual increase appearing in your bank account.
Equal Pay: The Foundation of Fair Compensation
When employers implement pay rises, they must do so in a manner that complies with equal pay legislation. The Equality Act 2010 is the cornerstone of this principle, mandating that men and women must receive equal pay for doing 'equal work'. The law defines 'equal work' broadly, encompassing situations where a person is employed to do the same or similar work, work that is broadly similar, or work that is of equal value. This means that pay disparities cannot exist between employees of different sexes who are performing comparable roles, possessing similar skills, and facing similar responsibilities, unless the difference can be objectively justified by a factor other than sex.
The right to equal pay is not limited to specific types of employees; it applies universally across the workforce. This includes:
- Employees
- Workers
- Apprentices
- Agency workers
- Individuals on full-time, part-time, or temporary contracts
- Self-employed individuals hired to personally perform work
When considering pay rises, employers must conduct thorough reviews to ensure that any increases are applied fairly and do not inadvertently create or perpetuate pay gaps based on gender. A pay rise should be based on merit, performance, or objective criteria, not on an employee's sex.
When Does the Pay Increase Start? A Summary
To summarise, a pay rise can start at different times depending on the reason for the increase:
| Trigger for Pay Rise | When the Increase Typically Starts | Key Considerations |
|---|---|---|
| TUPE Transfer (Contractual Entitlement) | Immediately upon transfer, if your contract guarantees it. Changes by the new employer are restricted. | Your original contract terms, including pay rise clauses, are protected. |
| National Minimum Wage Increase | From the start of the next pay reference period after the NMW rate change. | Applies to those on or near the NMW rates. Age and apprenticeship status are relevant. |
| Equal Pay Adjustments | As soon as the adjustment is made by the employer to rectify an inequality. | Ensures equal pay for equal work, regardless of gender. |
| Annual Salary Review / Performance | As specified in your contract or company policy (e.g., anniversary date, end of financial year). | Dependent on employer's review cycle and individual performance. |
Frequently Asked Questions
Q1: If my company is bought by another company, when will my pay rise entitlement transfer?
Under TUPE regulations, your existing contractual entitlements, including any guaranteed pay rises, transfer automatically to the new employer. The effective date of transfer is when the new employer takes over.

Q2: I'm 18 and paid the National Minimum Wage. When will I get a pay rise if the rates increase?
If the government increases the NMW rates and you qualify for a higher rate due to your age, your pay will increase from the start of the next pay reference period after the new rates come into effect.
Q3: My colleague, who does the same job as me, got a larger pay rise. Could this be an equal pay issue?
If you believe you are doing work of equal value to your colleague and there is a disparity in pay rises that cannot be objectively justified by factors other than gender, it could be an equal pay issue. You may wish to discuss this with your employer or seek advice.
Q4: Can an employer change my pay rise entitlement after a TUPE transfer?
An employer can only change your contractual terms, including pay rise entitlements, after a TUPE transfer if specific conditions are met, often involving consultation or objective justification for changes related to economic, technical, or organisational reasons.
Q5: What is a 'pay reference period'?
A pay reference period is the fixed period of time for which an employer calculates wages and makes payments, such as a week or a month. Changes to pay rates, like NMW increases, take effect from the start of the next such period.
Understanding these different triggers and regulations is key to ensuring your hard-earned pay increases are applied correctly and on time. Always refer to your employment contract and company policies for specific details relating to your situation.
