There is no single, reliable success rate for clinical negligence solicitors because firms handle different types of cases and may define “success” differently, such as settlement or winning at trial. A solicitor should assess your medical records, evidence of negligent treatment, and the impact of any injury before advising whether your claim has reasonable prospects. You can ask an SRA-regulated solicitor about their relevant experience, how they report outcomes, likely costs, and whether they offer a conditional fee agreement. Any outcome remains uncertain and depends on the evidence and the defendant’s response.
