Could you get opt-out compensation? 

When people hear about a large group action worth millions – or even billions – of pounds, one of the first questions they usually ask is: Can I get a share of the compensation? 

The answer depends on the type of claim, who is eligible, how the case is resolved, and what the court decides. 

In this guide, we explain how compensation works in UK opt-out collective actions, including what happens if a claim succeeds, how settlements are distributed and what you may need to do to receive your share of any money due. 

Key takeaways

What is an opt-out claim?

An opt-out claim is a type of collective legal action that allows a large group of people to be represented together in a single case. Rather than requiring every affected person to actively sign up, eligible individuals are automatically included in the claim unless they choose to opt out. 

The idea is simple. If millions of people may have suffered the same harm, it is often more practical to deal with the issue through one collective case rather than millions of separate lawsuits. 

Could you be missing out on compensation you are entitled to?

If you’ve had a mobile phone contract, paid for apps or subscriptions, shopped in the UK, or used every day digital services, there is a real chance that at least one opt-out case affects you. 

What are the benefits of opt-out claims?

Opt-out claims are designed to make it easier for consumers to access compensation, particularly where: 

What type of claims are opt-out?

Most UK opt-out claims are brought in the Competition Appeal Tribunal (CAT) under competition law. Examples include claims involving technology companies, digital marketplaces, telecommunications providers and other large businesses. 

However the Law Commission of England and Wales is currently reviewing whether a broader consumer class actions regime — potentially including expanded opt-out proceedings — should be introduced.  

Some legal commentators expect the review to consider whether opt-out collective consumer claims could potentially apply to other areas such as data breaches and privacy issues, consumer protection breaches, and environmental harm.

Does joining an opt-out claim cost anything?

If you are automatically included in an opt-out claim, there is usually nothing to pay. 

In most cases: 

The litigation is typically funded by specialist litigation funders who agree to cover the costs of the claim in return for a share of any recovery if the case succeeds. The exact funding arrangements vary from case to case. 

What happens if an opt-out claim wins?

There are generally two ways an opt-out claim can succeed: 

In either scenario, the court must consider how compensation should be distributed. The process is often more complicated than in an ordinary individual claim because the affected group may include hundreds of thousands – or even millions – of people. 

Will everyone receive the same amount of compensation?

Not necessarily. The amount someone receives depends on the nature of the claim and the harm that has allegedly been suffered.  In some cases, compensation may be divided equally between eligible class members. In others, payments may vary depending on factors such as: 

The court will normally approve the proposed distribution method before compensation is paid. 

How do courts calculate compensation?

When it comes to calculating compensation, every case is different.

Some claims allege that consumers paid higher prices than they should have due to anti-competitive conduct. Others may involve businesses being overcharged or prevented from competing fairly. 

The court’s role is to assess the evidence and determine whether harm occurred and, if so, how much compensation should be awarded to the group as a whole. This is often based on complex economic analysis. 

What happens if there is a settlement?

Many collective actions settle before reaching a final trial. If a settlement is proposed, it must usually be approved by the Competition Appeal Tribunal before it can take effect. 

The Tribunal will consider whether the settlement is: 

The settlement will normally include details of: 

Do I have to do anything to receive compensation?

Often, yes. Although people may be automatically included in an opt-out claim, there is usually a separate process for claiming compensation if the case succeeds. This is because the administrators need to verify who is entitled to receive a payment. 
 
If the claim succeeds or settles, eligible consumers often have to register to receive their share of any compensation.  
 
Depending on the case, you may be asked to: 

The exact requirements will depend on the claim. 

What if I do nothing?

The consequences of doing nothing depends on the case and the distribution method approved by the court. 

In some situations, compensation may be distributed automatically if sufficient records already exist. 

However, in many cases, eligible individuals will need to come forward and submit a claim before they can receive payment. This is one reason why many people choose to register for updates on collective actions that may affect them. 

What happens if not everyone claims?

In some opt-out cases, only a small percentage of eligible consumers have actually come forward to receive compensation payments. 

Where the total amount of available compensation is greater than the amount ultimately claimed by eligible individuals, the consequences are real.  
 
In some cases:  

For example, in the Gutmann v Stagecoach case, a settlement of up to £25 million was originally approved in 2024, with around 1.4 million rail passengers affected. But by mid-2025, just over £200,000 had been claimed and fewer than 1% of eligible people came forward. The CAT described uptake as “extremely disappointing”. Because uptake was so low, the total settlement fund was reduced. In January 2026, the Access to Justice Foundation announced that £3.7 million in unclaimed compensation from the collective action would be redistributed to fund free legal advice services across England, Scotland and Wales.

When large amounts of compensation go unclaimed, it raises questions about whether the system is really delivering justice to the people it was designed to protect. 

How to find out if you are included in a claim

If an opt-out claim is certified, information is usually published explaining: 

Many consumer claims also have an official claim website with updates, so people can follow the progress of the litigation and receive important announcements. 
 
However, at Join the Claim, we believe that opt-out collective actions are failing ordinary people because:

Opt-out collective actions: frequently asked questions

An opt-out collective action is a specific type of legal claim brought on behalf of everyone affected by the same competition law issue. If you meet the eligibility criteria, you are included automatically unless you choose to opt out. You usually only need to take action if compensation becomes available.

No. If you meet the eligibility criteria, you are usually included automatically unless you opt out. However, being included in the claim is not always the same as receiving compensation. If the claim succeeds or settles, you may still need to register, confirm your details or provide evidence before you can receive any money. 

No. You will only receive compensation if the claim succeeds, settles, and you meet the requirements of the compensation process. Some claims fail. Some settle. Some continue for several years. Even where money becomes available, eligible people may still need to claim their share before a deadline. 

If compensation becomes available, there will usually be a claims process. This may ask you to complete a form, confirm your contact details and provide evidence that you fall within the eligible class. The exact process depends on the case and the distribution plan approved by the Competition Appeal Tribunal. 

No. Individual consumers usually do not need to go to court. The claim is brought by a class representative on behalf of the wider group. The representative, legal team and funders manage the case. 

Being included in an opt-out claim does not usually cost consumers anything. 
The claim is normally funded by litigation funders or other funding arrangements. If the claim succeeds or settles, the Tribunal may approve deductions for legal costs, funding costs or administration costs before compensation is paid. 

That depends on the case. In some opt-out claims, each person may receive the same amount. In others, payments may depend on how much you spent, how long you were affected, what product or service you used, or what loss you suffered. 

Individual payments can be modest, especially where harm is spread across millions of people. But without the collective action, many people would receive nothing at all. 

Many opt-out claims involve small losses suffered by a very large number of people. For example, a company may be accused of overcharging millions of consumers by a relatively small amount. The total claim can be very large, even if each person’s individual share is lower. 

Opt-out claims can take several years.  Even after a settlement or judgment, extra time is usually needed to finalise the distribution plan, open the claims process, verify eligibility and make payments. 

If you don’t register during the claims process, you may miss out on compensation — even if you were eligible. This is why awareness matters. Many people lose out simply because they never hear about the claim in time. 

Information is usually published on the official claim website, in court-approved notices and through updates from the class representative. 

There is no single national alert system for all opt-out claims, which means many people may not hear about compensation unless they actively follow developments. 

Platforms like Join the Claim help by providing updates on opt-out claims. 

Being included means you fall within the eligible group represented by the claim. Claiming compensation usually means taking a later step to receive money after the claim succeeds or settles. This may involve registering, confirming your details or submitting evidence. 

Yes. If you do not want to be included, you can usually opt out by following the process set out in the court-approved notice. There will normally be a deadline for doing this.

No. Being included in an opt-out collective action does not affect your credit score, financial record, or ability to use a company’s services.

No. Join the Claim is not a law firm and does not give legal advice. We explain collective actions, track major cases, and direct people to trusted, official claim information so they can make informed decisions.

Because there is no sign-up phase at the start. Cases can take years, official notices are often technical, and communication is limited. As a result, many people only hear about claims after the opportunity to participate has passed. 

You may miss out. Although you may be included automatically at the start, you may still need to take action later to claim your share of any compensation. If you miss the deadline, you may not receive a payment. 

Unclaimed compensation may be dealt with in different ways, depending on the case and the court-approved arrangements. In some opt-out competition claims, unclaimed damages can be directed to another approved use. In settlements, the position can be more complex and will depend on the terms approved by the Tribunal.

Opt-out claims include eligible consumers automatically. Opt-in claims require individuals to actively sign up and instruct a law firm. Many people confuse the two, which is another reason opt-out claims are often missed.
