Compensation Events
NEC Compensation Events: a practitioner guide to notification, quotation and assessment
Most NEC compensation events fail not because the law is hard, but because the discipline is. Here is what the clauses say, where the work breaks down, and what good looks like, written from live UK NEC contract administration.

NEC Early Warning vs Compensation Event: when one becomes the other
Most teams treat early warnings and compensation events as separate processes. The contract treats them as one register with different obligations attached. Get the judgement wrong and you either spam EWs that should have been CEs, or sit on CEs that should have been notified weeks earlier.

Contract Options
NEC Option A vs Option C: where the misapplication trap lives
Option A is not a fixed price. Option C is not cost reimbursable. The two most-used NEC Options on UK infrastructure are also the two most-misapplied. The misapplication is rarely caught at procurement. It surfaces in the numbers, six months in.

Resolution routes we cover
Five mechanisms. Each with its own commercial register.
NEC4 builds in three contractual routes; the UK construction landscape adds the TCC and arbitration on top. The choice of route shapes timing, cost, finality, and the evidence burden on each Party.
Option W1
Adjudication when the Construction Act doesn't apply
Used outside the UK or where the Housing Grants, Construction and Regeneration Act 1996 doesn't bite. The procedure is contractual: notice of dispute, Senior Representatives, then an Adjudicator chosen under the contract.
Option W2
Adjudication under the Construction Act
The default UK route on NEC4. Either Party can refer a dispute at any time. Twenty-eight days from referral to decision in theory; longer in practice with extensions. Decisions are temporarily final.
Option W3
Dispute Avoidance Board
Standing panel that visits the project regularly and issues recommendations on disputes when asked. Designed to surface and settle issues before formal adjudication is needed.
TCC
Technology and Construction Court
Specialist division of the High Court. Hears enforcement of adjudicators' decisions and substantive construction disputes. The TCC's published guidance and judgments are the closest thing to a public benchmark for outcomes.
Arbitration
CIArb / institutional arbitration
Where the contract elects arbitration as the tribunal route. Confidential, often slower than adjudication enforcement, used on complex factual disputes and on international NEC contracts.
