A ready-to-complete template for issuing NEC4 early warning notices under clause 15. Correctly structured to meet the NEC4 requirements, with guidance on what to write in each field to protect your programme and defined cost position.
The header identifies the notice as a formal NEC early warning and provides the reference information needed for the risk register. Every field must be completed.
The event description is the factual account of the matter that could increase defined cost, delay completion, or impair performance. Be precise and factual.
Under NEC4, an early warning that leads to a compensation event entitles you to additional defined cost. Quantify the potential cost impact as clearly as possible.
Programme impact must be assessed separately from cost. A delay event may push back completion even if its direct cost is modest.
Under NEC4 clause 15, early warning notices must be entered in the risk register. Include the risk register reference in your notice to prompt the contractor to act.
Issue early warning notices as soon as you become aware of any matter that could increase defined cost, delay Completion, or impair performance of the works — do not wait until you can quantify the full impact.
Complete the notice header fully, including a sequential EWN number and the date of issue. Send the notice to the contractor's project manager (as named in the contract data), not just the site manager.
In the event description, be specific and factual. Name the programme activity, design submission, or contract obligation that has not been met. Attach supporting evidence — an email, programme extract, or photograph — where available.
Provide a preliminary estimate of cost and programme impact. You do not need a precise figure at this stage — a reasonable estimate with a clear explanation of your assumptions is sufficient to meet the NEC4 obligation.
Explicitly request that the matter is entered on the risk register and, if urgent, request an early warning meeting. State clearly what action you require from the contractor's PM.
