The Short Answer
Typical Timescales at a Glance
6–12 months
Straightforward claim settling at pre-action protocol stage
12–24 months
Contested claim requiring expert evidence and negotiation
2–4 years
Complex claim proceeding to a full court trial
The honest answer is: it depends. Professional negligence claims vary enormously in complexity, and the timescale depends on whether liability is disputed, whether expert evidence is needed, and whether the professional's insurer is willing to engage constructively.
What we can tell you is that the vast majority of professional negligence claims settle before trial — and many settle at the pre-action protocol stage, before court proceedings are even issued. The key is to start the process promptly and to be represented by a solicitor who knows how to move the claim forward efficiently.

Stage by Stage
The Professional Negligence Claims Process
Here is what happens at each stage of a professional negligence claim, and how long each stage typically takes.
Initial Assessment & Investigation
- We review the facts of your case and the professional's conduct
- We obtain and review all relevant documents (contracts, reports, correspondence)
- We assess whether the professional's conduct fell below the required standard
- We identify the loss you have suffered and how it was caused
- We advise on the strength of your claim and the likely value
This phase can take longer if documents need to be obtained from third parties or if expert evidence is required at an early stage.
Pre-Action Protocol — Letter of Claim
- We send a detailed Letter of Claim to the professional or their insurer
- The Letter of Claim sets out the facts, the alleged negligence, and the loss claimed
- The professional has 21 days to acknowledge the letter
- The professional then has 3 months to investigate and respond
- We review the Letter of Response and advise on next steps
The pre-action protocol is a mandatory step before issuing court proceedings. Many claims settle at this stage — often within 3–6 months of the Letter of Claim being sent.
Expert Evidence & Negotiation
- If liability is disputed, we instruct an independent expert in the relevant field
- The expert reviews the professional's conduct and provides a written report
- We use the expert report to negotiate with the professional's insurers
- We may engage in without prejudice negotiations or mediation
- Many claims settle at this stage without the need for court proceedings
Expert evidence is often the key to resolving a disputed professional negligence claim. A strong expert report significantly increases the prospects of early settlement.
Court Proceedings (if required)
- If the claim cannot be settled, we issue court proceedings
- The claim is allocated to the appropriate track (fast track or multi-track)
- Both parties exchange witness statements and expert reports
- The court lists the case for trial — typically 12–18 months after issue
- Most cases settle before trial, often at a joint settlement meeting
Court proceedings are a last resort. The vast majority of professional negligence claims settle before trial — often at mediation or a joint settlement meeting shortly before the trial date.
What Causes Delays
Factors That Can Slow Down Your Claim
Understanding what causes delays helps you set realistic expectations — and helps us take steps to minimise them.
Disputed Liability
If the professional denies negligence, you will need expert evidence to establish that their conduct fell below the required standard. Obtaining and exchanging expert reports takes time.
Complex Loss Calculations
Where the loss is complex — for example, a lost business opportunity or a failed investment — it may be necessary to instruct a forensic accountant or other specialist to quantify the claim.
Multiple Defendants
Where more than one professional is potentially liable — for example, a solicitor and a surveyor both involved in the same transaction — the claim becomes more complex and takes longer to resolve.
Insurer Delays
Professional indemnity insurers sometimes take longer than the protocol allows to investigate and respond. We will chase the insurer and, if necessary, apply to the court for permission to issue proceedings early.
Court Backlogs
If the claim proceeds to court, the time to trial depends on the court's listing availability. In some courts, particularly in London, the wait for a trial date can be 18–24 months after proceedings are issued.
Do Not Delay — Limitation Periods Are Strict
The standard limitation period for professional negligence claims is 6 years from the date of the negligent act. If you are approaching this deadline, you should seek advice immediately. We can issue protective proceedings quickly to preserve your position — even if the claim is not fully prepared.
Once the limitation period has expired, your claim is almost certainly lost — regardless of how strong it is on the merits.
Common Questions
Frequently Asked Questions
How long does a typical professional negligence claim take to settle?
A straightforward claim where liability is not seriously disputed can settle within 6–12 months of us being instructed. A more complex claim where liability is contested and expert evidence is required typically takes 12–24 months. Claims that proceed to a full trial can take 2–4 years from instruction to judgment.
Can I speed up my professional negligence claim?
Yes. The most important things you can do are: instruct a solicitor promptly (delay can prejudice your claim and ultimately cause it to be time-barred); gather and preserve all relevant documents; respond quickly to requests for information from your solicitor; and be prepared to consider reasonable settlement offers rather than insisting on the maximum possible recovery.
What is the pre-action protocol and why does it take so long?
The Pre-Action Protocol for Professional Negligence is a mandatory procedure that must be followed before issuing court proceedings. It requires you to send a detailed Letter of Claim to the professional, who then has 21 days to acknowledge it and 3 months to investigate and respond. The protocol is designed to encourage early settlement and avoid unnecessary litigation. The 3-month investigation period is the main reason the pre-action stage takes time — but it also gives the professional's insurers an opportunity to settle the claim without the cost and risk of court proceedings.
Will my claim definitely go to court?
No. The vast majority of professional negligence claims settle before trial — typically at the pre-action protocol stage or after proceedings are issued but before the trial date. Court proceedings are a last resort, and both parties have strong incentives to settle: the professional's insurer wants to avoid the cost and uncertainty of a trial, and you want to recover your loss without the stress and delay of litigation.
What happens at mediation in a professional negligence claim?
Mediation is a voluntary, confidential process in which both parties meet with a neutral mediator to try to reach a settlement. The mediator does not decide the case — they facilitate negotiation between the parties. Mediation is increasingly common in professional negligence claims and has a high success rate. It typically takes place over one day and can resolve claims that have been in dispute for months.
Does no win no fee affect how long the claim takes?
No. The funding arrangement — whether no win no fee, private retainer, or legal expenses insurance — does not affect the timescale of the claim. The claim proceeds at the same pace regardless of how it is funded.
What is the limitation period for professional negligence claims?
The standard limitation period is 6 years from the date of the negligent act. If you did not discover the negligence at the time, the period may run from the date you knew (or ought reasonably to have known) about the negligence — subject to a longstop of 15 years from the negligent act. If you are approaching the limitation deadline, you should seek advice immediately — issuing proceedings to protect your position can be done quickly even if the claim is not fully prepared.
