Mediation Lawyers United Kingdom 2026: Mandatory Mediation, CPR Changes & Costs

For mediation lawyers in the United Kingdom, 2026 marks a decisive shift in how courts approach alternative dispute resolution. A series of Civil Procedure Rule practice-direction updates, Family Procedure Rule pilots, and strengthened judicial encouragement have moved the landscape closer to effectively mandatory mediation for many commercial and family disputes. This guide explains the current legal position, the procedural steps counsel must take when a court directs mediation, and the realistic costs and sanctions exposure for parties that refuse. As at 7 May 2026, every litigation team should treat engagement with mediation not as optional goodwill, but as a core compliance obligation with direct cost consequences.

Will Mediation Be Mandatory in the UK in 2026?, Legal and Pilot Landscape

Mediation is not yet mandatory by statute in England and Wales, but courts now possess and routinely exercise the power to order parties to engage in non-court dispute resolution, including mediation. The practical effect for commercial litigators is that declining mediation without a compelling, documented reason carries serious risk.

Recent pilots and policy nudges, a timeline

The trajectory toward mandatory mediation UK practice has accelerated over the past two years. Key milestones include:

• October 2023, Churchill v Merthyr Tydfil CBC (Court of Appeal). The Court of Appeal confirmed that courts can lawfully order parties to engage in ADR processes, including mediation, provided the order does not impair the right of access to the court. This landmark ruling overturned the longstanding assumption derived from Halsey v Milton Keynes General NHS Trust [2004] that compulsory mediation was impermissible.
• December 2024, GOV.UK mediation providers list. The Ministry of Justice published an updated procurement list of approved mediation providers, signalling continued government investment in ADR infrastructure.
• 2024–25, Family Procedure Rule pilots. Pilots in selected courts introduced automatic referral to mediation information and assessment meetings (MIAMs) for certain private-law children and financial-remedy cases, with non-attendance triggering cost consequences.
• 2025–26, Strengthened practice directions. Updated practice directions supporting CPR Parts 1 and 26 reinforce the court’s active case-management duty to encourage ADR at every stage, with directions to mediate becoming a standard feature of case management conferences in the Business and Property Courts.

What “mandatory” means in practice, court-directed vs statutory compulsion

Industry observers expect the gap between “strongly encouraged” and “compulsory” to continue narrowing. In practice, the distinction matters less than many assume. A court order directing mediation carries judicial authority: ignoring it exposes the refusing party to adverse cost orders, potential strike-out of unreasonable conduct arguments, and reputational harm before the trial judge. While Parliament has not enacted a statute requiring mediation as a pre-condition to litigation, the combined effect of Churchill, updated practice directions, and increased judicial willingness to penalise non-engagement means that, for all practical purposes, commercial mediation in 2026 functions under a regime of strong judicial compulsion.

Can the Court Order Mediation in Commercial Disputes? What Happens If Parties Refuse?

Yes, following Churchill v Merthyr Tydfil CBC, courts in England and Wales have clear authority to order parties to engage in court-ordered mediation. The key constraint is proportionality: any order must not effectively deny a party access to trial.

Procedure when a court orders mediation, immediate steps

When a mediation direction is made, counsel should act within the following framework:

• Within 48 hours: Acknowledge the order in writing; notify the client and any co-parties; begin identifying potential mediators from the Civil Mediation Council’s accredited panel or the court’s approved list.
• Within 14 days (or as directed): Agree or propose a mediator; exchange position statements; set the mediation date within the court’s timetable.
• Pre-mediation: Prepare a concise case summary and supporting bundle; ensure the client representative attending has authority to settle; brief the client on the costs exposure if mediation fails due to non-engagement.

Grounds to resist a mediation order, making a reasoned application

Resistance is possible but rarely successful. Courts have accepted the following narrow grounds:

• Disproportionate cost: The mediation would cost more than the amount in dispute, rendering it disproportionate to the issues.
• Previous failed mediation: The same parties have already attempted mediation on the same issues and it broke down in good faith.
• Urgent injunctive relief: The nature of the claim requires immediate court intervention (e.g., freezing orders, anti-suit injunctions) that mediation cannot provide.
• Evidenced bad faith: There is clear, documented evidence that the opposing party intends to use the process solely for delay or disclosure abuse.

When applying to resist, counsel should file a concise witness statement addressing these factors specifically, supported by a costs estimate showing why mediation is unreasonable in the circumstances. Vague objections, such as asserting that the case is “too complex”, are routinely rejected.

Mediation Costs and Sanctions, What Happens If You Refuse or Unreasonably Resist

Unreasonable refusal to mediate can lead to adverse costs orders, including indemnity costs. The severity of the sanction depends on the reasonableness of the refusal and the procedural context in which it occurs.

Key costs principles from recent case law

The courts have progressively tightened the consequences for mediation refusal. In Halsey v Milton Keynes General NHS Trust [2004], the Court of Appeal set out factors for assessing whether a refusal to mediate was unreasonable, including the nature of the dispute, the merits of the case, and whether ADR had a reasonable prospect of success. While Churchill [2023] expanded judicial power to order mediation, the Halsey factors remain relevant to costs assessment after the event. Early indications suggest that post-Churchill courts are less sympathetic to mediation refusal and more willing to impose indemnity costs where a party has ignored a clear judicial direction.

Mediator fees and typical cost ranges, family vs commercial

Understanding mediation costs and sanctions begins with knowing the base expense. According to the Civil Mediation Council and published provider schedules:

• Family mediation: Typically £100–£250 per person per session for legally-aided cases; private mediations range from £200–£500 per person per session depending on complexity and location.
• Commercial mediation (sub-£500k disputes): Mediator fees generally range from £1,500–£3,500 per party for a one-day mediation, excluding venue and counsel costs.
• High-value commercial mediation (£1m+): Senior mediator rates of £3,000–£7,500+ per party per day are common, with total costs (including venue, counsel preparation, and attendance) routinely reaching £15,000–£30,000 per side.

Even at the upper end, these figures remain a fraction of the cost of a multi-day Commercial Court or Technology and Construction Court trial, which reinforces the court’s expectation that mediation represents proportionate expenditure.

CPR and Family Procedure Rule Changes Affecting Mediation (2024–26)

Key rule changes, timeline and effect

The CPR mediation rules landscape has evolved rapidly. The following changes are particularly relevant to mediation lawyers in the United Kingdom advising on commercial and civil disputes:

• CPR Part 1.4(2)(e), overriding objective. The court’s duty to further the overriding objective includes encouraging the parties to use ADR. Post-Churchill, this duty is interpreted as encompassing the power to order, not merely encourage, mediation.
• CPR Part 26 and Practice Direction 26, allocation and case management. Directions questionnaires now include enhanced ADR prompts. Parties must confirm whether they have considered mediation and, if not, explain why. Failure to engage with this process invites judicial scrutiny at the first case management conference.
• Pre-Action Protocols, general and sector-specific. The overarching Practice Direction on Pre-Action Conduct and Protocols requires parties to consider ADR before issuing proceedings. Updated sector-specific protocols (construction, professional negligence, clinical disputes) place additional emphasis on early mediation as a step that the court expects to see attempted.
• Family Procedure Rules, MIAM requirements and pilot expansions. In family proceedings, attendance at a MIAM is a statutory prerequisite before issuing certain applications. Pilot schemes have extended automatic mediation referral to a wider range of cases, with non-compliance resulting in adjournment and cost consequences.

Practical impact for commercial practitioners

For solicitors and barristers handling commercial disputes, the practical effect of these changes is threefold. First, pre-action letters should now routinely include a clear, dated offer to mediate, and should specify a proposed mediator, available dates, and the issues suitable for resolution. Second, any resistance to mediation must be recorded in writing with reasons, contemporaneously, to preserve a costs argument at trial. Third, timetabling should build in a mediation window before the pre-trial review, because courts increasingly decline to grant adjournments for late-stage mediations that could have occurred earlier.

Commercial Court, TCC and Multi-Party Mediation Considerations

Technology and Construction Court mediation practice

Technology and Construction Court mediation has its own distinct culture. The TCC Guide actively encourages ADR and expects parties to have attempted mediation before the first case management conference. Judges in the TCC regularly make ADR orders at the CMC stage, with a standard direction requiring the parties to report back on the outcome. Given the technical complexity of TCC disputes, often involving multiple experts and sub-contractors, the court recognises that mediation can resolve not just the principal claim but also contribution and indemnity disputes that would otherwise generate satellite litigation.

Multi-party mediation, lead party strategy and process design

Multi-party commercial mediations require careful process architecture. Counsel should address the following:

• Mediator selection: Agree a single mediator with relevant sector expertise; use the Civil Mediation Council panel or seek a joint appointment through the court if parties cannot agree.
• Position statements: Coordinate cascading position statements so that each party’s case is clear before the mediation day, avoiding ambush and enabling focused negotiation.
• Authority and settlement structure: Ensure every attending party has a representative with full settlement authority. In multi-party mediations, cascading or contingent offers (e.g., “Party A will contribute X if Party B contributes Y”) require pre-agreed frameworks.
• Breakout room logistics: For five or more parties, plan breakout room allocation and mediator rotation in advance to avoid dead time on the mediation day.
• Costs sharing: Agree the split of mediator and venue costs before the mediation; in default, equal division is conventional but can be adjusted by agreement or court order.

Enforceable Settlements and Converting Mediated Outcomes Into Consent Orders

Settlement agreements, structure and pitfalls

A mediated settlement is only as valuable as its enforceability. The enforceable settlement protocol requires attention to several critical details. The settlement agreement must be signed by all parties (or their authorised representatives) on the day or within a specified timeframe. It should identify the parties, the claims resolved, the consideration, and any ongoing obligations. Ambiguity in drafting is the most common cause of post-mediation disputes, particularly around confidentiality carve-outs, payment schedules, and the treatment of costs.

Tomlin orders and consent judgments

To convert a mediated settlement into an enforceable court order, practitioners have two principal options:

• Tomlin order: The preferred route in most commercial mediations. The order stays proceedings on agreed terms scheduled to the order, with liberty to apply to enforce those terms. This preserves confidentiality (the scheduled terms need not be publicly filed) while giving the settlement the enforceability of a court order.
• Consent judgment: Appropriate where the settlement involves a simple monetary payment and the parties do not require confidentiality. The judgment is entered by consent and is immediately enforceable through standard enforcement mechanisms.

In family proceedings, mediated financial settlements must typically be embodied in a consent order approved by the court under the Matrimonial Causes Act 1973 to be binding. The court retains a supervisory jurisdiction and may decline to approve terms it considers manifestly unfair.

Hybrid and Remote Mediation Best Practice in 2026

Technology, confidentiality and document management

Hybrid mediation practice has matured significantly since 2020. In 2026, most commercial mediations offer a hybrid option, some parties in the room, others attending remotely. Key considerations for counsel include ensuring that the video-conferencing platform supports secure, encrypted breakout rooms; that shared documents are hosted in a controlled data room with audit trails; and that screen-sharing protocols prevent inadvertent disclosure of privileged material to the wrong breakout group.

Tips for counsel instructing remote or hybrid mediations

• Test technology 48 hours before. Verify connectivity, breakout-room functionality, and screen-sharing permissions for every participant.
• Agree a protocol for joint sessions. Specify who speaks, for how long, and whether cameras are mandatory, this avoids the loss of engagement that afflicts poorly structured remote joint sessions.
• Manage time zones and fatigue. For international multi-party mediations, cap each session at four to five hours with structured breaks. Fatigue degrades negotiation quality faster in remote settings than in person.
• Preserve confidentiality. Remind clients that remote attendance from open-plan offices or shared spaces risks inadvertent waiver of without-prejudice privilege. A private, soundproofed room is essential.

Practical Templates and Checklists for Mediation Lawyers in the United Kingdom

48–72 hour checklist when a court directs mediation

• Acknowledge the court direction in writing to all parties and the court.
• Brief the client on the mediation process, costs exposure, and the consequences of non-engagement.
• Propose three potential mediators from the Civil Mediation Council register or court-approved list.
• Circulate three available dates within the court’s directed window.
• Begin preparing a concise position statement (no more than ten pages plus key documents).
• Confirm the client representative who will attend with full settlement authority.

Template response to a mediation direction, key bullet points

• “We acknowledge the court’s direction of [date] ordering the parties to engage in mediation.”
• “We propose [Mediator Name], accredited by the Civil Mediation Council, as mediator for this dispute.”
• “We are available on [dates] and invite the [Claimant/Defendant] to confirm their availability within 7 days.”
• “We confirm that [Client Name / representative] will attend with authority to settle up to [level / full authority].”

Key points to brief the client on costs and sanctions

• Refusing mediation without documented, compelling reasons risks adverse costs orders, potentially on an indemnity basis.
• Attending but without genuine engagement (e.g., sending a junior representative without authority) is treated by the court as constructive refusal.
• Mediation costs are typically a fraction of trial costs and may be recoverable as part of a costs order if the case proceeds to judgment.

Conclusion, Counsel Takeaway

The landscape for mediation lawyers in the United Kingdom has fundamentally changed. The question is no longer whether to mediate, but how to do so effectively and in compliance with the court’s expectations. Following Churchill v Merthyr Tydfil CBC, the courts possess unambiguous authority to order mediation, and the CPR framework reinforces this at every procedural stage, from pre-action correspondence through to case management and costs assessment.

For general counsel, in-house legal teams, and commercial litigators, the compliance imperative is clear: build mediation into your dispute-resolution strategy from the outset, document every offer and response, and ensure that any resistance is grounded in specific, defensible reasons. The cost of a one-day mediation is a fraction of a contested trial; the cost of unreasonably refusing one can be an adverse indemnity costs order that dwarfs the mediator’s fee.

Early, well-prepared engagement with mediation is now the single most effective risk-management step available to parties in UK litigation. Practitioners who treat this obligation as a procedural formality, rather than a genuine opportunity to resolve disputes, do so at their clients’ significant financial peril.
