IT consultant and developer claims: project and SLA examples

Reviewed by Apex Insurance Brokers · Last reviewed 2026-08-05

Software and IT consulting is high-value, deadline-driven work where a single missed milestone can cascade into real financial loss for a client. When that happens, the client rarely blames "bad luck" — they blame the supplier. Professional indemnity insurance exists to respond when a client alleges your advice, code or project management fell short and cost them money.

Below are anonymised, illustrative examples of how claims arise for IT professionals, how they connect to service level agreements, and where the line between PI and cyber cover sits. These are composites, not real named cases, but they reflect the pattern of disputes brokers see across the sector.

Common IT claim scenarios

Missed go-live deadline. A development consultancy contracts to deliver an e-commerce replatform ahead of a retailer's peak trading period. Integration testing slips, go-live is delayed by several weeks, and the client alleges lost sales and additional contractor costs. The claim turns on whether the delay was negligent or driven by client-side scope changes.

Defective release. A freelance developer pushes an update that introduces a calculation error into a client's billing system. Customers are under-charged for a period before it is spotted. The client seeks the shortfall plus the cost of remediation and customer communications.

SLA breach. A managed service provider commits to 99.9% uptime and a four-hour response window. A misconfiguration causes an outage that exceeds the agreed threshold. The client invokes service credits and then pursues a wider loss claim for downtime.

Scope and specification dispute. A consultancy delivers a system that meets the written spec, but the client argues it does not do what was "obviously intended." The disagreement escalates into a claim over fitness for purpose and wasted expenditure.

Negligent advice. An architect-level consultant recommends a technology stack that later proves unfit for the client's scale. The client alleges the recommendation was negligent and claims the cost of rebuilding. Apex places professional indemnity across 18 professions, with specialist rather than generalist IT consultant PI broking covered on a page of its own.

How SLAs shape a claim

Service level agreements are a double-edged sword in a dispute. A clear SLA defines your obligations and can cap your exposure through agreed service credits and liability limits. But it also creates a measurable benchmark: if you promised 99.9% uptime or a fixed delivery date, a shortfall is easy for a client to point to.

Two things matter when a claim follows an SLA breach:

• What the contract actually says. Liability caps, exclusion of consequential loss, and defined remedies (such as service credits) heavily influence what a client can recover.
• Whether the failure was negligent. PI responds to negligence, not to every contractual shortfall. Insurers and their solicitors look closely at cause — a client change request, third-party outage or unrealistic timeline can shift responsibility.

A well-drafted contract with proportionate liability limits is one of the strongest defences you have. Your broker and insurer will often ask to see your standard terms when arranging cover.

Where PI and cyber overlap

IT work sits at the crossover point of two policies. Professional indemnity covers claims that your work was negligent. Cyber insurance covers the consequences of a security or data event — a breach, ransomware, or data loss — including your own first-party costs. Many IT claims touch both.

The overlap is why gaps appear. A client whose data is exposed because of a coding error might argue both negligence (PI) and a data breach (cyber). If you hold only one policy, an insurer may point to the other. Arranging PI and cyber together — ideally so the wordings dovetail — avoids the argument over which policy responds. An anonymised example: a consultancy building a customer portal left an unsecured endpoint, records were scraped, and the client pursued both negligent development and breach-notification costs. Two policies were needed to answer the whole claim.

What PI typically covers for IT work

• Damages or settlements a client is awarded for negligent work, advice or delay.
• Legal defence costs — often the largest early expense, even where a claim ultimately fails.
• Mitigation and rectification costs where the policy allows, to limit a loss before it grows.
• Breach of contract and negligence allegations arising from your professional services.

Cover limits are usually offered as generic options such as £1m, £2m or £5m. The right level depends on your contract values, the size of clients you serve and any minimum limits those clients require in their supplier agreements. Many enterprise and public-sector clients specify a minimum PI limit before they will engage a supplier.

Reducing the risk of a claim

• Use written contracts with clear scope, acceptance criteria and change-control processes.
• Set realistic SLAs and liability caps, and exclude consequential loss where you can.
• Keep a documented trail of client sign-offs, change requests and testing.
• Report circumstances to your insurer early — PI is usually written on a claims-made basis, so late notification can prejudice cover.

Common questions

Do service credits count as a claim? Not usually. Service credits are a contractual remedy paid by you, not an insured loss. A claim arises when a client pursues wider financial losses beyond the agreed credits — that is where PI may respond.

Is a missed deadline enough to trigger PI? Only if the delay resulted from negligence and caused the client financial loss. A delay driven by client scope changes or third-party failures may not be your liability at all — cause is central to any claim.

Do I need cyber cover as well as PI? For most IT firms handling client systems or data, yes. PI answers negligent work; cyber answers breaches, ransomware and data-loss costs. Held together, they close the gaps that a single policy leaves open.
