Understanding Pay Rises in the UK: What Employers Need to Know About Employment Contracts and Legal Obligations

There’s a lot of buzz about pay rises in the UK-whether it’s the annual pay review season, a long-awaited employee request, or a question about “what is a good pay rise UK businesses should offer”. If you’re running or managing a business, you might be wondering: How do pay rises actually work? What are your legal responsibilities? And how do employment contracts tie into it all?

The pressure to get pay rises right isn’t just about employee satisfaction-there are real legal implications if you get it wrong. Making informed decisions, having clear documentation, and staying compliant with employment law can help your business attract talent, boost morale, and avoid unnecessary disputes.

In this guide, we’ll break down everything you need to know as an employer about UK pay rises: how they work, what legal obligations you have, and how to handle pay increases properly in the context of employment contracts. If you want to be confident-and compliant-when it comes to managing pay raises, keep reading.

What Is a Pay Rise in the UK?

A pay rise simply means an increase in an employee’s salary or wages. In the UK, pay rises can happen in different ways and for various reasons. They may be:

• Automatic (such as annual cost-of-living adjustments or increments linked to performance reviews)
• Negotiated (after an employee requests a raise or as part of promotion discussions)
• Mandated (in response to changes in the National Minimum Wage or National Living Wage rates)

The average yearly pay rise in the UK varies by industry and economic climate, but recent data suggests employers commonly offer between 3% and 6% increases. Of course, what’s considered a “good” pay rise depends on your sector, local competition, and financial circumstances.

Remember, while many employees look for an annual pay rise, there’s no automatic right to one unless stipulated in the employment contract or a company policy.

What Laws Govern Pay Rises in the UK?

UK employers have to navigate a few essential legal requirements when it comes to pay rises. The relevant rules include:

• The National Minimum Wage Act 1998 and National Living Wage obligations
• The Employment Rights Act 1996, which covers employment contracts and pay statements
• Anti-discrimination laws (ensuring increased pay is not awarded in a discriminatory way)

Let’s break these down a bit further.

Minimum Wage and Legal Minimum Pay Increases

From April each year, the UK government may increase the National Minimum Wage and National Living Wage. This means any employee earning less than the new minimum must have their pay increased-regardless of what their contract says.

It’s crucial for employers to stay up to date with the latest minimum wage rules to avoid expensive penalties and claims from underpaid staff.

Contractual Rights to a Pay Review or Pay Rise

Your business may have obligations to consider or award pay rises if your employment contract (or a staff handbook) sets out regular pay reviews or guaranteed increases. For example, if your contract says, “You are entitled to an annual pay review,” you must carry this out in good faith-though you do not always have to grant a pay rise unless the contract specifies it.

But beware-if your contract promises a specific increase (e.g., “You will receive a 5% annual pay rise”), you are legally bound to deliver it as written. Failure to do so could mean a breach of contract claim.

Avoiding Discrimination in Pay Rises

UK law prohibits pay rise decisions based on protected characteristics such as age, gender, race, or disability. Unequal pay or unjustified differences in raises between staff doing similar roles can run afoul of discrimination laws or Equal Pay rules.

It’s sound business practice to have a clear, objective process for awarding pay rises-and to record your reasons to protect your business if challenged.

How Do Employment Contracts Affect Pay Rises?

Employment contracts are the cornerstone of your obligations around pay rises. Here’s what you need to know:

What Should Your Employment Contract Say?

A well-drafted contract will explain:

• How often pay is reviewed (e.g. annually, six-monthly)
• Whether pay rises are automatic or at the employer’s discretion
• The basis for awarding a pay rise (e.g. performance, length of service, profitability)
• Any link to statutory changes (e.g. pay will rise in line with minimum wage increases)

Be careful not to over-promise. “You may be considered for a pay rise” gives you flexibility, while “You will receive a pay rise of at least x% each year” commits you to a binding obligation.

Not sure if your contracts are up to scratch? It’s wise to review your staff contracts regularly as your business evolves or get them professionally checked by an employment lawyer.

Changing Pay: When and How Can You Amend Contracts?

If you wish to implement a new pay rise structure, reduce pay, or alter the timing of reviews, this counts as a change to the terms of employment. You generally cannot do this unilaterally-you’ll need the employee’s consent or to follow a formal process for changing contracts.

What Is a “Good” Pay Rise in the UK?

This is one of the most common questions for employers: what amount is fair, competitive, and sensible?

• The average yearly pay rise UK businesses offer varies, but in 2024, surveys show a range of 3% to 5% for most private sector jobs.
• High performers, in-demand roles, or industries facing skills shortages may see larger increases.
• An annual pay rise in the UK might match inflation (the Consumer Price Index-CPI), or surpass it if your business is doing well and you want to retain talent.

When deciding what to offer, consider these practical tips:

• Benchmark against industry averages (look for data relevant to your size, sector, and region)
• Be mindful of National Minimum Wage and Living Wage increases
• Factor in company profitability and plans for growth
• Document your rationale (this helps with staff transparency and legal protection)

Do Employers Have to Give Annual Pay Rises?

There is no legal requirement for an employer to grant a pay rise every year-unless your contract or company policy says so, or you need to raise salaries to keep pace with statutory minimums.

However, regular pay reviews are common. Many businesses promise to review pay “at least annually”, but the outcome of that review is at management’s discretion unless otherwise agreed in writing.

If you do not grant pay rises, be sure to document your reasons. Avoiding or refusing a pay rise without a good, non-discriminatory reason-and failing to communicate this properly-can harm employee morale and may cause legal trouble if the decision appears discriminatory.

What Are the Legal Risks if You Get Pay Rises Wrong?

Pay rises and pay reviews can cause friction and legal disputes if mishandled. The main risks for employers include:

• Breach of contract-Not awarding increases in line with what was contractually promised
• Unlawful deductions from wages-If an employee’s pay drops below what’s legally owed or contractually agreed after a supposed “increase” (e.g. switched to commission pay that ends up lower)
• Discrimination claims-If pay rise decisions systematically disadvantage staff with a protected characteristic (gender, age, etc.)
• Minimum wage breaches-Paying less than the legal minimum after a rate rise can result in fines and back pay claims

Getting legal advice before altering pay structures or making business-wide pay decisions is a smart way to avoid expensive claims or regulatory investigations.

How Should UK Employers Manage Pay Rises in Practice?

• Have a clear policy: Set out your process (how and when pay is reviewed, who decides, how it’s communicated) in a written policy or staff handbook. This supports consistency and fairness.
• Communicate clearly: Tell staff when pay reviews will happen, whether a pay rise is guaranteed or discretionary, and how decisions are reached.
• Record decisions: Confirm any pay rise, change in pay, or contract amendment in writing (ideally with a signed document or letter).
• Review and update contracts: Make sure your contracts are robust, updated, and reflect your real-world processes-a contract review is worthwhile if your business has grown or changed since they were drafted.
• Stay compliant: Monitor legal changes (like minimum wage rates) and review your pay strategy each year.

It’s also good practice to revisit your pay rise process every year to keep up with best practices, new laws, and evolving expectations in your sector.

FAQs About Pay Rises: What Do Employers Ask Most?

Is There a Legal Maximum to How Much You Can Raise Pay?

No, there’s no government cap on salary increases. However, internal company bandwidth and consistency should be considered-to avoid inadvertently creating pay inequalities.

What’s the Average Raise After 1 Year of Work in the UK?

This varies a lot, but studies show the average is around 3%-5%. High-performers or those in fast-growing companies might see more.

Should Pay Rises Be the Same for Everyone?

No, but the process and rationale must be objective (e.g., linked to performance, length of service, or defined scales) and non-discriminatory. If you have a discretionary system, document the business reasons for different increases.

Can Employees Insist on a Pay Rise Because of Inflation?

Not unless the contract states pay will increase with inflation or CPI. However, failing to keep pace with wider market norms may affect retention.
