Most homeowners facing a building dispute think in terms of court. It's the familiar model: someone sues someone else, a judge decides, someone pays. But for construction disputes, court is often the last resort rather than the obvious path. Two alternatives, mediation and adjudication, are faster, cheaper and frequently more effective. Understanding both will help you choose the right approach for your situation.
Mediation: Negotiated Settlement
Mediation is a structured negotiation facilitated by a neutral third party. The mediator doesn't make a decision or impose an outcome. Their job is to help both parties understand each other's positions and find a mutually acceptable settlement.
For domestic building disputes, a mediation session typically lasts one day, takes place at a neutral venue (often a solicitor's offices), and involves each party presenting their position to the mediator, followed by private caucus sessions where the mediator works with each side separately. The majority of mediations settle on the day, or within a few days of the session.
The advantages are significant. Mediation is confidential, so neither party can use what's said in mediation as evidence in any subsequent court proceedings. It's substantially cheaper than adjudication or litigation. And because both parties have to agree to any settlement, the outcome tends to be one that both can live with, which matters when you still have to live next door to each other or complete the remaining work.
Costs vary, but a mediator for a domestic building dispute might charge £1,500-£3,000 for a day's session. Splitting the fee equally between parties is conventional. Add your own legal preparation costs and you might be looking at £3,000-£5,000 total for both parties combined. Compare that to adjudication or litigation and the cost differential is significant.
When to use mediation: It's most useful when both parties have something to lose from a prolonged dispute and are genuinely open to settlement. It doesn't work well when one party is acting in bad faith or when the legal position is clear and one party simply needs to be compelled to comply.
Adjudication: Fast-Track Binding Decision
Adjudication is a statutory right in most construction contracts, introduced by the Housing Grants, Construction and Regeneration Act 1996. A party to a construction contract can refer a dispute to adjudication at any time. An adjudicator (an independent construction professional, usually a solicitor, barrister, surveyor or engineer with specific training) is appointed, both sides submit their evidence and arguments, and the adjudicator issues a binding decision, typically within 28 days.
The decision is immediately enforceable through the courts. The losing party must pay what's decided, and can only challenge the decision on very limited procedural grounds. The whole process, from referral to decision, usually takes four to six weeks.
It's important to note that adjudication was designed primarily for commercial construction contracts. Its application to domestic homeowner contracts (where the homeowner is a residential occupier) is more complex, since the HGCRA excludes certain residential contracts. However, many JCT domestic contracts include adjudication provisions as a matter of contract rather than statute, making it available regardless.
The Adjudication Process in Practice
The process starts with the referring party (the one with the claim) issuing a Notice of Adjudication, setting out briefly what the dispute is and what they're seeking. An adjudicator is then nominated, either by agreement or by an Adjudicator Nominating Body (ANB) such as RICS, RIBA or the Chartered Institute of Arbitrators.
The referring party then submits their full case (the Referral Notice) within seven days, typically a detailed document with supporting evidence, photographs, expert reports and legal arguments. The responding party has time (usually seven to fourteen days) to respond. The adjudicator may ask questions of both parties before issuing their decision.
The speed is the point. Twenty-eight days from referral to binding decision is remarkable by the standards of any dispute resolution process. The downside is that twenty-eight days is also a very short time to prepare a complex case, and the costs of preparing a proper referral can be significant: legal fees, expert witness fees, and the adjudicator's own fees (which must be paid regardless of outcome, though the adjudicator can apportion them).
Costs of Adjudication
Be realistic about costs before embarking on adjudication. A typical adjudication for a domestic dispute might cost:
- Adjudicator's fees: £3,000-£8,000 (complex cases can be much more)
- Legal preparation (your side): £3,000-£10,000 depending on complexity and legal representation
- Expert witness fees if needed: £2,000-£5,000
For a dispute over £20,000-£30,000, adjudication can make financial sense. For a dispute over £8,000, it probably doesn't. This is why the small claims court (for amounts under £10,000) or mediation are often more appropriate for lower-value domestic disputes.
Arbitration: The Third Option
Arbitration is sometimes confused with adjudication but is quite different. It's a private judicial process where an arbitrator (appointed by agreement or by a professional body) hears the full case from both sides and issues a final, binding award. It's more thorough than adjudication but considerably slower and more expensive. It's rarely the right first choice for domestic homeowner disputes but may be appropriate for very high-value, complex cases where privacy and finality are priorities.
Which Route to Choose
There's no single right answer, and the appropriate route depends on the amount in dispute, the nature of the problem, whether the other party is acting in good faith, and what outcome you're actually seeking.
As a rough guide: for disputes under £10,000, start with informal resolution, try mediation, and use Small Claims Court as a last resort. For disputes between £10,000 and £50,000, mediation first, then adjudication if mediation fails. For disputes over £50,000, get a construction solicitor involved early and let them advise on the most appropriate route given the specific circumstances.
