Most people who are owed compensation for a data breach never pursue it. Not because their claim lacks merit. Not because they don’t have the evidence. Because they assume hiring a solicitor costs money they don’t have, and they quietly absorb the loss.
That assumption is wrong. The standard arrangement for data breach claims in the UK is no-win-no-fee: the solicitor takes their fee from your award if you win, and you pay nothing if you lose. The barrier isn’t cost. It’s knowing where to start and what questions to ask when you get there.
This article is for educational purposes only and does not constitute legal advice. Consult a qualified solicitor or attorney for advice on your specific situation.
The short answer: A no-win-no-fee data breach solicitor takes their fee (usually 25–35%) only if you win, and charges nothing if you lose. To choose one, get a free consultation with a specialist UK firm, ask about the success fee, disbursements, and ATE insurance, and check the firm on the SRA register first. Walk away from any firm charging upfront fees, guaranteeing an award, cold-calling you, or posing as a solicitor while being a claims management company.
Do data breach solicitors cost you anything upfront?
Conditional Fee Agreements (CFAs) — the formal name for no-win-no-fee in UK law — are routine in data breach claims. The solicitor agrees to take your case without charging you by the hour. If you win, they take a percentage of your award as their success fee. If you lose, their fee is zero.
There are a few things to clarify before you sign anything (we’ll get to that). But the core principle is solid: you can pursue a claim worth thousands of pounds without any upfront outlay. The solicitor’s incentive is aligned with yours. They only get paid if they win for you.
This is why it’s worth making the call even if you’re not sure your claim is strong enough. A good data breach solicitor will tell you in a free initial consultation whether your case has merit. That costs you nothing.
What does “no win no fee” actually mean?
The success fee is typically 25–35% of your damages. Do the maths before you start: a £3,000 award with a 35% success fee means £1,050 goes to the solicitor and you receive £1,950. That’s still money you didn’t have before. But you should go in understanding the numbers, not find out after.
Disbursements are the part most people miss. Disbursements are out-of-pocket costs: court filing fees, expert witness fees, medical report fees. Some CFAs cover these entirely if you lose; others don’t. Before you sign, ask explicitly: “If I lose, am I liable for any disbursements?” Get the answer in writing.
After the Event (ATE) insurance is often bundled with a CFA. ATE covers your opponent’s legal costs if the court orders you to pay them — which is rare but possible if a claim is pursued unreasonably. The ATE premium is typically deducted from your award if you win; it’s not an upfront cost. Ask whether your solicitor arranges ATE on your behalf and what the premium is.
The honest version: no-win-no-fee data breach claims are a good deal for most claimants. The deductions are real, but they come from money you wouldn’t have otherwise. Just understand the structure before you commit.
UK specialist firms that handle data breach claims
These are established practices with track records in data breach litigation — not an exhaustive list, but a reliable starting point.
Hayes Connor Solicitors is one of the largest specialist data breach practices in the UK. They run group actions against major organisations including British Airways and NHS Trusts. If your breach is a high-profile one with an existing group action, Hayes Connor is worth checking first — joining a group action often means lower deductions for individual claimants.
JMW Solicitors has a strong data protection team based in Manchester. They handle both individual claims and group actions, and their initial enquiry process is clear and fast.
Keller Postman UK brings a US mass-litigation model to UK data breach claims. They’re particularly active in large group actions and have the infrastructure to pursue high-volume cases efficiently.
Slater and Gordon is a major personal injury firm with a dedicated data breach team. Good for individuals who want a well-resourced firm with a straightforward process and accessible communication.
Richard Nelson LLP operates as a boutique data protection practice — smaller, but particularly suited to complex individual claims where you want specialist attention rather than a high-volume operation.
All of these firms offer free initial consultations. Most have online enquiry forms; expect a response within a few working days. There’s no obligation after the consultation.
Questions to ask in the first consultation
Write these down before the call. A good solicitor will answer them clearly; a poor one will be evasive.
- What is your success fee percentage?
- Am I responsible for disbursements if I lose, and what disbursements are likely in my case?
- Do you arrange ATE insurance, and what does the premium cost?
- Have you handled claims against this specific company before?
- Is my case better suited to a group action or an individual claim?
- What is your realistic estimate of the claim value and likely timeline?
- What documents do you need from me to assess the claim?
The answers to these questions tell you what you’re actually agreeing to. They also give you a basis for comparing two or three firms if you want to shop around before committing.
Red flags to walk away from
Not every firm operating in this space is reputable. Some are actively worse than going direct.
Upfront fees. No legitimate no-win-no-fee solicitor charges you upfront for a data breach claim. If a firm asks for a registration fee, a processing fee, or any payment before your claim resolves, walk away.
Claims management companies. These are not law firms — they’re intermediaries who take a percentage of your award (often 20–30%) and then instruct a solicitor anyway. You pay twice and get one service. Go direct to a solicitor and cut out the middleman. Some CMCs dress themselves up to look like law firms; check the SRA register (below) before signing anything.
Guaranteed award amounts. No solicitor can tell you exactly what you’ll receive before reviewing your case and the defendant’s response. Anyone who promises you a specific figure upfront is telling you what you want to hear, not what’s legally accurate.
Aggressive cold calling. Some operations harvest contact details from breach databases — somewhat ironic — and call potential claimants they’ve never heard from. Legitimate firms respond to enquiries; they don’t chase you down. If you didn’t initiate contact, be cautious.
Verify before you sign anything. The Solicitors Regulation Authority maintains a public register of all authorised solicitors in England and Wales. Check any firm at sra.org.uk/consumers/register/ before signing a retainer. If the firm doesn’t appear on the SRA register, they cannot legally act as solicitors.
For US readers: how it works differently
The US doesn’t have a direct GDPR equivalent that gives individuals the right to sue for data breach compensation in the same way. Individual claims are rare. The primary mechanism is the class action.
If your data was exposed in a US breach, you’re likely already a potential class member — you don’t need a personal attorney. Search for the breach name plus “class action settlement” to find the relevant case. Filing a claim on the settlement website is free and takes minutes. Payouts are often modest (£50–£200 per person), but so is the effort.
Do you have significant, documented losses from a US breach, such as substantial financial fraud, identity theft, or documented distress? A plaintiff’s attorney on a contingency fee arrangement (typically 30–40%) can pursue individual litigation. Firms that specialise in this include Morgan & Morgan, Console & Associates, and Turke & Strauss. Most offer free consultations.
Frequently asked questions
Is no-win-no-fee really free if I lose? With a proper Conditional Fee Agreement, you pay no solicitor fee if you lose. Confirm in writing whether you’re liable for disbursements, and ask if ATE insurance covers the other side’s costs.
How much does a no-win-no-fee solicitor take? The success fee is typically 25–35% of your damages. On a £3,000 award at 35%, the solicitor takes £1,050 and you keep £1,950. Disbursements and any ATE premium come out of the award too.
How do I know a firm is legitimate? Check the Solicitors Regulation Authority register before signing. Avoid firms that charge upfront fees, guarantee an award amount, or cold-call you. Claims management companies are not solicitors and add a second fee.
Do I need a solicitor for a US breach? Usually not. Most US compensation comes through class actions you can join free. See our class action guide and the wider compensation guide.
