Professional negligence claims in small claims court

Negligence is a legal test, not a feeling. All four must be present.

A professional you engaged owed you a duty to exercise the skill and care of a reasonably competent member of their profession.

Their work fell below that standard. Bolam test: would a reasonable body of competent practitioners in that field have done what they did?

Their breach caused your loss. But for their negligence, you would not have suffered the harm.

You suffered actual financial loss as a result. Inconvenience or distress alone is not enough.

The Bolam test in plain English

The standard isn’t whether the professional was the best in their field — it’s whether

a reasonable body of competent practitioners

in that profession would have done what they did. If yes, no negligence. If no — even if their action was within the range of acceptable practice — there may be a claim.

This is named after Bolam v Friern Hospital Management Committee [1957], originally a medical case but now applied across all professions. It sets a high bar: novel approaches and judgement calls within the profession’s acceptable range are not negligent, even if they turn out badly.
