If a defect has surfaced on a scheme you engineered, if a Notice of Adjudication has landed, if a contractor is blaming a design detail, or if a completed project has thrown up something that could develop into a claim, this entry sets out how a UK engineer should think about the next 24 to 48 hours. It covers notification under the claims-made wording, why timing is critical, what the Engineering Council and the professional institutions expect in parallel, and what your broker does at this point. Read it once, then pick up the phone.
Engineers' PI is written on a claims-made basis. The wording responds to claims and to notified circumstances arising during the period of insurance, not to matters that arose during it but were never told to the insurer. Section 3 of the Insurance Act 2015 imposes the duty of fair presentation at inception, renewal and any material variation; section 13A gives the insured a route where an insurer has breached the implied term to pay claims within a reasonable time. Late notification is one of the largest single technical reasons claims run into trouble at coverage stage. Notifying does not commit you to admitting anything — it preserves the year's cover you have already bought.
A claim under an engineer's PI wording does not need to be a court proceeding. It can be a letter from a client, a Notice of Adjudication, an email from the contractor pointing at a design detail, a Party Wall or approved-inspector observation being attributed to your role, a collateral warranty beneficiary raising a defect, or an internal note that a chartered engineer at director level would read as something that might turn into a claim. The wording standard is that a fact, matter, event or circumstance which may reasonably be expected to give rise to a claim must be notified. The test is objective, and once someone senior has spotted it the practical clock has started.
The Engineering Council maintains the UK register of professional engineers (CEng, IEng, EngTech) under Royal Charter. The Statement of Ethical Principles, jointly published by the Engineering Council and the Royal Academy of Engineering, frames the ethical baseline. The professional institution the engineer holds membership of — the Institution of Civil Engineers (ICE), the Institution of Structural Engineers (IStructE), the Institution of Mechanical Engineers (IMechE) or the Institution of Engineering and Technology (IET) — publishes its own Rules of Professional Conduct or Code of Conduct, and each institution operates a disciplinary process that can run in parallel with a civil claim. Where the matter concerns a building within scope of the Building Safety Act 2022, s.135 of the BSA has extended limitation for defective-dwelling claims under s.1 of the Defective Premises Act 1972 and the interaction with collateral warranties, net contribution clauses, and reliance letters becomes central. Where a scheme has statutory approval implications — CDM 2015, Building Regulations, higher-risk building gateways under the BSA — parallel regulatory contact may be required.
Do not respond to the client, main contractor or beneficiary on substance until you have notified your broker. Preserve every drawing revision, calculation, model, inspection note, meeting minute and email trail. Do not annotate or "tidy" a project archive after the event. Do not admit liability, offer a fee reduction that reads as an admission, or float a settlement figure in correspondence. Notify your broker straightaway; the broker handles the notification to the insurer in the form the wording requires and manages what happens next. If a Notice of Adjudication has been served, or a limitation deadline is running, tell the broker in the first conversation — that changes the sequence.
A named broker who has run engineers' notifications before will take the summary from you, prepare and submit the notification to the insurer in the form the wording requires, protect your position on scope and late-notification questions, and manage the appointment of defence solicitors from the insurer's approved panel. From there the broker deals with any reservation of rights letter, the reserve conversation, coverage arguments around collateral warranty beneficiaries, net contribution and design-and-build interfaces, and BSA-related limitation questions on residential higher-risk buildings. Apex is a broker, not an insurer or a defence firm; the broker handles the notification and manages the process with the insurer's appointed defence panel. This is where broker experience earns its keep.
Not because Apex clients never have claims. Engineering is a long-tail exposure by design, and defects can surface many years after practical completion. Apex clients renew because when a matter arose, the notification was made properly, the year's cover attached, and the practice reached the next renewal in a position to place terms on the merits rather than under a cloud.
Notification urgent?
If a matter has just arisen, call now. Late notification is one of the largest single reasons claims get declined. A named broker will pick up the phone and start the notification with you.
