If a solicitor, accountant, surveyor, financial adviser or other professional has let you down, the cost of taking action can feel like a second blow on top of the original loss. That is where no win no fee funding comes in.
It lets you pursue a professional negligence claim without paying your lawyer's hourly rate as you go, shifting much of the financial risk off your shoulders. But no win no fee is not quite as simple as the name suggests.
There are success fees to understand, insurance products that often sit alongside the arrangement, and situations where you could still end up paying something out of pocket. This guide walks through how conditional fee agreements actually work in practice, what to look for before you sign one, and the questions worth asking any lawyer who offers this funding route for a negligence claim.
Overview
A no win no fee arrangement is the everyday name for a Conditional Fee Agreement, or CFA. It is a written contract between you and your legal representative which says that their fees only become payable if your claim succeeds.
If the case is lost, you do not pay your own lawyer's professional charges. CFAs were introduced to broaden access to justice, so that people with a genuine grievance are not priced out of bringing a claim simply because they cannot fund a court battle from savings.
In professional negligence work, CFAs are common because claims often turn on complex evidence and expert reports, which can make traditional hourly billing unaffordable for ordinary clients. A CFA typically includes a success fee, which is an uplift on the lawyer's normal charges payable only if you win.
It is important to understand the difference between your lawyer's fees, the other side's costs, and disbursements like court fees and expert reports, because each can be treated differently under a no win no fee arrangement.
Key steps
Check you have a viable negligence claim. Before any funding discussion, you need a realistic basis for saying a professional fell below the standard expected of a reasonably competent practitioner in their field, and that this caused you measurable loss. A lawyer will usually assess the merits before agreeing to take the case on a no win no fee basis.
Get a written CFA and read it carefully. The conditional fee agreement must be in writing and should set out the success fee percentage, what counts as 'winning', what happens if you end the agreement early, and how disbursements are handled. Do not rely on verbal assurances, everything that matters should be on the page.
Consider After The Event (ATE) insurance. ATE insurance covers you against having to pay the other side's legal costs and certain disbursements if you lose. Many no win no fee cases are run alongside an ATE policy. Premiums vary, and in most modern cases they are not recoverable from the losing party, so check who pays and when.
Understand the success fee cap and deductions. The success fee is a percentage uplift on your lawyer's base costs, taken from your compensation if you win. In many consumer claims the deduction from damages is capped, but professional negligence has its own commercial realities, so ask for a worked example showing what you would actually receive.
Keep communication clear throughout the claim. Once the CFA is signed, stay engaged with the process. Respond promptly to requests for documents, witness statements and instructions on settlement offers. Settling too early or rejecting a reasonable offer can have cost consequences, even under a no win no fee deal.
Common questions
Q Does no win no fee really mean I pay nothing if I lose?
It means you do not pay your own lawyer's professional fees if the claim fails. However, you could still be liable for disbursements like court fees, barristers' fees or expert reports unless these are covered by ATE insurance or your CFA specifically says otherwise. You may also be ordered to pay some of the other side's costs. Always ask for a clear written breakdown of every scenario before signing.
Q What is a success fee and how much can it be?
A success fee is an extra percentage added to your lawyer's standard charges, payable only if you win. It reflects the risk the lawyer took in running the case without guaranteed payment. The maximum success fee is set by regulation and is typically expressed as a percentage uplift on base costs. In consumer-type claims there are also caps on how much can be deducted from your damages, so always ask for the specific figures in writing.
Q Will every solicitor take a professional negligence case on no win no fee?
No. Lawyers assess the strength of the claim, the value, the defendant's ability to pay and the likely costs before agreeing. Cases that are factually complex, low in value or have weak evidence may be declined. If one firm turns a claim down it does not always mean the case is hopeless, another firm with different specialisms may take a different view.
Q What is ATE insurance and do I need it?
After The Event insurance is a policy taken out once a dispute has arisen, designed to cover adverse costs and sometimes your own disbursements if the claim fails. It often sits alongside a CFA to give you full protection. Whether you need it depends on the case, the defendant and your appetite for risk. Your lawyer should explain the available options and the premium terms before you commit.
Q Can I change lawyers during a no win no fee case?
You can, but there may be consequences. Some CFAs require you to pay the outgoing firm's costs if you terminate the agreement without good reason. Others allow the file to transfer with the CFA intact. The specific terms in your agreement control what happens, which is why reading the termination clauses carefully before signing really matters.
Q How long do professional negligence claims usually take?
There is no fixed timeline. Straightforward cases that settle early might resolve within several months, while disputed claims that go to trial can take a couple of years or longer. Limitation periods also apply, generally six years from the negligent act for contract-based claims, though the rules around when the clock starts can be complex. Act quickly and take guidance on time limits.
Q Will I definitely keep most of my compensation if I win?
Most, but not all. Under a CFA, a portion of your damages can be used to pay the success fee and any unrecovered costs or insurance premiums. The exact split depends on the terms you agreed and the court's cost orders. A reputable lawyer will give you an illustrative example at the outset so there are no surprises at the end.
