Mediation is a structured form of facilitated negotiation in which an independent neutral assists the parties to a dispute to reach a settlement, conducted under a written mediation agreement with confidentiality and without prejudice protections.
Mediation is the most widely used form of formal ADR in UK civil and commercial litigation. A trained mediator — often a senior barrister or solicitor, sometimes a specialist mediation practitioner — facilitates the negotiation between the parties through a structured process of joint sessions and private caucuses. The mediator does not impose a decision; the parties retain control of the outcome and can walk away at any point.
For insurance claims, mediation is the principal alternative to (or precursor to) a JSM. The mediator’s involvement adds a neutral perspective, can break impasses where the parties’ negotiating styles clash, and lends the process a credibility that bilateral negotiation sometimes lacks. Mediation success rates in commercial disputes are typically reported at 70-80%.
Mediation is supported by the CPR overriding objective (CPR 1.1) and is increasingly mandated or strongly encouraged in many courts. Key authorities:
Civil Mediation Council standards apply to accredited mediators. The Centre for Effective Dispute Resolution (CEDR) is the most prominent UK mediation provider; many other providers operate in specialist domains (construction, family, employment, international commercial).
Mediation discussions are protected by:
These layers combine to create a strong (though not absolute) protection for mediation communications. The exceptions are similar to the without prejudice exceptions in Unilever v Procter & Gamble.
The Mediation Act 2024 (where relevant; check current status) and the EU Mediation Directive (which informed earlier UK practice) provide additional structural support.
A mediation is typically organised four to eight weeks in advance. The parties (or their solicitors) agree:
On the day, the mediator opens with a joint session, then moves to private caucuses with each side. The mediator shuttles between the parties carrying messages, testing positions and exploring options. The mediator’s skill is in asking the right questions, identifying common ground and managing the parties’ emotional and tactical reactions.
A successful mediation ends with heads of terms signed before the parties disperse. Typical mediation success rates exceed those of bilateral negotiation alone because the mediator can reframe positions, identify previously overlooked options and build the necessary trust between the parties.
For insurance claims, mediation is particularly valuable in three scenarios. First, where the parties have a continuing relationship that bilateral negotiation might damage. Second, where the personalities of the lawyers or principals have prevented effective bilateral negotiation. Third, where the claim has multiple parties and the bilateral negotiating model would not scale.
The mediator’s role is facilitative, not evaluative. Some mediators occasionally give a non-binding evaluation of the merits if the parties request it; most do not, preferring to leave the merits assessment to the parties’ own lawyers.
“Early neutral evaluation” (ENE) is a related ADR technique in which a neutral gives a non-binding view on the merits; closer to evaluation than facilitation.
“Med-arb” combines mediation with arbitration: the mediator becomes the arbitrator if mediation fails. Rare in UK practice because of confidentiality concerns.
“Mediation with a wrap” — combining mediation with a binding final-offer arbitration to deal with any remaining gap. Used occasionally in complex commercial matters.
“Online mediation” — entirely virtual mediation conducted by video, increasingly common post-2020. Some practitioners find it less effective for highly emotional disputes; others find it more efficient.
“Single-text” mediation — used in multi-party disputes, where the mediator drafts a proposed settlement and circulates it for comments and modifications.
A long-running dispute between an asset manager and its D&O insurer over a £12m enforcement-related claim is referred to mediation. The mediator is a former Commercial Court judge. The mediation is held over two days at a London City venue. Day 1 morning: joint opening session with each side’s leading counsel presenting an outline of its position; lunch break with informal exchange between the principals; afternoon caucuses in which the mediator separately tests each side’s bottom line. Day 1 ends with the parties’ positions at £6.4m (asset manager) and £4.2m (insurer), a £2.2m gap. Day 2 morning: mediator-driven exploration of structuring options including staged payment, deferred element, indemnity for related future events. Day 2 afternoon: agreement on £5.6m headline plus structured indemnity for a specific future-claim risk. Heads of terms signed at 17:45 on day 2; documented as a Tomlin order with confidential schedule within 21 days. Mediation cost (both sides combined including mediator fees): approximately £140,000. Avoided trial costs (estimated): £1.2m+.
