How UAE Energy Subcontracts Allocate Risk

• UAE law permits subcontracting without employer consent unless the main contract expressly prohibits or restricts it. The main contractor remains fully liable to the employer for the subcontractor's performance.
• There is no direct contractual relationship between a subcontractor and the project owner under UAE law. Article 891 of the Civil Transactions Law prohibits a subcontractor from claiming against the employer unless the main contractor has assigned that right.
• Pay-when-paid clauses are enforceable in the UAE, but the good faith obligation under Article 246 of the Civil Code limits how they can be applied in practice.
• Flow-down clauses in UAE energy EPC contracts routinely impose on subcontractors the same HSE obligations, time bar requirements, liability caps, and dispute resolution procedures that govern the main contract. A subcontractor that signs without reviewing these provisions accepts obligations it may have no practical ability to perform or enforce.
• Federal Decree-Law No. 25 of 2025 — the new UAE Civil Transactions Law, effective 1 June 2026 — introduces material changes to the construction contracts framework, including express provisions on hardship, termination for convenience, and decennial liability recovery against subcontractors.

Who this applies to

This article is written for contractors and subcontractors operating in UAE energy projects — upstream oil and gas, downstream processing, LNG, and power generation — and their in-house counsel, contract managers, and commercial teams. It is also relevant to project owners and developers seeking to understand the liability chain below the main contract level. It does not address construction projects outside the energy sector in detail, though much of the analysis applies equally to major infrastructure and industrial projects.

The legal baseline: no privity, full contractor liability

The starting point under UAE law is Article 890(2) of the Civil Transactions Law, which states that the main contractor remains wholly and directly liable to the employer for work performed by its subcontractors. Subcontracting transfers execution responsibility to another party but does not transfer contractual responsibility to the employer. If a subcontractor causes delay, performs defective work, or fails entirely, the main contractor bears the consequences under the main contract.

This principle applies regardless of whether the subcontractor was chosen by the main contractor or nominated by the employer. The Dubai Court of Cassation considered this in a 2008 decision where it held that where a subcontractor is chosen by the employer or its consultants, the employer bears accountability for delay caused by that nominated subcontractor — but only where the main contractor can demonstrate that the delay was solely attributable to the nominated party and that the main contractor had no involvement. That is a high evidentiary bar, and the safer position for main contractors is to resist nomination where possible or to negotiate an express indemnity in the main contract for losses arising from nominated subcontractor performance.

For energy lawyers in the UAE advising on either side of the subcontract relationship, the absence of any direct legal relationship between subcontractor and employer is the structural fact from which everything else follows.

Flow-down clauses: what they pass down and why it matters

In UAE energy projects, the dominant contracting framework is FIDIC — typically the 1999 Silver Book for EPC/turnkey projects, with the 1999 Red Book appearing in more traditionally procured projects. FIDIC contracts are almost never used unmodified. Main contractors and project owners, including ADNOC and its operating subsidiaries, use particular conditions to shift risk allocations substantially toward the contractor. Those shifts then flow downstream.

A flow-down clause — sometimes called a "back-to-back" clause — requires the subcontractor to assume toward the main contractor all obligations that the main contractor has assumed toward the employer in respect of the subcontracted scope. In its most aggressive form, a flow-down clause simply states that the subcontract is "back-to-back" with the main contract and incorporates the main contract by reference. In its more careful form, it selectively passes down specific provisions.

The practical consequence for subcontractors in UAE energy projects is that they are routinely bound by provisions that were negotiated between a major international EPC contractor and a sophisticated national oil company, without having any input into those negotiations and often without having seen the full main contract terms. The provisions most likely to create serious exposure include the following.

FIDIC 28-day time bar. Under Sub-Clause 20.1 of the 1999 FIDIC Red Book and Sub-Clause 20.2 of the 2017 edition, a contractor must give notice of a claim within 28 days of becoming aware of the event giving rise to it. If this obligation flows down to the subcontract, a subcontractor faces the same 28-day clock — and in some cases a shorter one if the main contractor has imposed additional upstream notice requirements on itself. Missing the deadline extinguishes the claim. The DIFC Court of Appeal confirmed the condition precedent nature of this clause in Panther Real Estate Development LLC v Modern Executive Systems Contracting LLC in 2023. A subcontractor that fails to preserve this right loses it regardless of how meritorious the underlying claim is.

Liquidated damages exposure. The main contract will typically impose liquidated damages for delay at a daily rate calculated against the total contract value. Where delay LDs flow down to the subcontractor proportionate to their scope, and where the subcontract does not mirror the main contract's extension of time mechanisms, the subcontractor can find itself bearing LD exposure for delays it did not cause and cannot defend against through the subcontract's own terms.

HSE and regulatory obligations. ADNOC and its operating companies impose comprehensive HSE requirements on their contractors, including incident reporting obligations, safety management system standards, and permit-to-work regimes. These requirements are reflected in main contracts and flow down to subcontractors. A subcontractor that does not implement a compliant HSE management system before mobilisation is technically in breach from day one.

Variation and change order procedures. Energy EPC contracts impose strict procedural requirements for the submission and approval of variations. If those procedures flow down and the subcontractor fails to follow them, the variation claim is lost regardless of the merits. In practice, subcontractors at the lower tiers of the chain frequently perform additional work on instruction and then discover they cannot recover for it because the procedural path was not followed.

Liability caps: what UAE law permits and what it does not

UAE law gives parties significant freedom to contractually limit liability, but that freedom has mandatory limits that apply regardless of what the contract says.

Consequential loss exclusions. It is standard in UAE energy subcontracts to exclude indirect and consequential losses, including loss of profit, loss of production, loss of use, and loss of contract. The UAE Civil Code supports enforcement of these exclusions where the clause is clear and the parties have defined what it covers. Where the clause uses general language and does not specifically enumerate the excluded heads of loss, courts and tribunals applying UAE law will assess the parties' common intention. Poorly drafted exclusion clauses create uncertainty at precisely the moment when it is most commercially significant. Under the new Civil Code effective from 1 June 2026, where a clause is genuinely ambiguous, Article 266 of the current code — providing that doubt is construed in favour of the debtor — is preserved and refined.

Liability caps and indemnities. Main contracts in the energy sector routinely set an overall cap on the contractor's liability, expressed as a percentage of the contract price. Whether indemnities provided by the contractor or subcontractor sit inside or outside that cap is one of the most heavily negotiated points in any energy subcontract. A subcontractor that provides an indemnity for HSE incidents, third-party injury, or property damage without carving that indemnity out of the liability cap may find its overall cap is functionally meaningless — the indemnity obligation, if triggered, can exceed it.

Decennial liability: what cannot be excluded. Under Article 880 of the Civil Transactions Law, contractors and design consultants are jointly and strictly liable for structural defects in buildings and structures for ten years from completion. This cannot be excluded by contract. Article 882 confirms that any attempt to do so is void. In UAE energy projects, this means that a main EPC contractor facing a decennial claim from the project owner cannot simply point to its subcontractors. The liability sits with the main contractor regardless of who actually performed the defective work.

The new Civil Code (Federal Decree-Law No. 25 of 2025, effective 1 June 2026) introduces an important clarification. It expressly preserves the main contractor's right to pursue recovery against subcontractors for their contribution to a decennial liability event — but specifies that that recovery action is not itself subject to strict liability. The contractor must establish the subcontractor's fault and causation. This matters in two ways: it confirms the recovery right exists (which the current law is silent on), and it means main contractors and their insurers need to monitor the five-year contractual limitation period carefully. A decennial claim from the employer may arrive years after completion, by which point the underlying claim against the subcontractor could already be time-barred.

Pay-when-paid clauses: enforceable, but not absolute

Pay-when-paid clauses condition the main contractor's obligation to pay a subcontractor on the main contractor first receiving payment from the employer. They are enforceable under UAE law and commonplace in energy sector subcontracts.

The practical consequence for subcontractors is significant. Where the main contractor has not been paid — whether because of a dispute with the employer, an employer insolvency event, or a contested certification — the subcontractor has no contractual right to demand payment from the main contractor. It has performed work, incurred costs, and has no immediate remedy. The subcontractor's only option, absent an assignment or direct payment mechanism, is to wait or to challenge the pay-when-paid provision itself.

The challenge route has real but limited traction. Article 246 of the Civil Code imposes a good faith obligation on contracting parties. Courts have accepted that a pay-when-paid clause can be unenforceable in specific circumstances where it would be unconscionable to allow the main contractor to rely on it — for example, where the non-payment from the employer was caused by the main contractor's own breach, or where the main contractor is using the clause as a mechanism to defer payment indefinitely while the underlying employer dispute is unrelated to the subcontractor's scope. But this is not a general override of the clause. It requires a fact-specific argument.

The more reliable protection for subcontractors is structural: negotiating a direct payment mechanism with the employer at the outset, obtaining a performance guarantee or parent company guarantee from the main contractor, or negotiating a payment bond. In practice, subcontractors at the lower tiers of major ADNOC projects rarely have the leverage to insist on these protections, but the question should always be raised.

The nominated subcontractor problem

A nominated subcontractor is one selected by the employer or the engineer rather than by the main contractor. FIDIC Red Book Clause 5.2 gives the main contractor a right to object to nominated subcontractors on reasonable grounds. In practice, that right is often limited by the employer's particular conditions.

The liability position for nominated subcontractors under UAE law is technically the same as for domestic subcontractors: the main contractor remains liable under Article 890(2). But the Dubai Court of Cassation's 2008 decision provides a defence pathway where the main contractor can demonstrate that the delay or defect was caused solely by the nominated party and that the main contractor had no contributory role. That is a useful but narrow protection.

The more commercially relevant point is that the main contractor has limited ability to impose its usual subcontract terms on a nominated subcontractor who was brought to the project by the employer. Nominated subcontracts are frequently negotiated under time pressure with a party that the main contractor did not choose and may not have done business with before. Ensuring that flow-down clauses are properly incorporated and that liability and payment terms are consistent with the main contract requires more diligence in the nominated context, not less.

What the 2026 Civil Code changes mean in practice

Federal Decree-Law No. 25 of 2025 is the most significant overhaul of UAE civil law since 1985. For energy project subcontracts, three changes are directly relevant.

Hardship exception for lump-sum contracts. The new code introduces an express hardship provision. Where exceptional circumstances arise that were unforeseeable at the time of contracting and that substantially upset the contractual balance, the dispute resolution forum is expressly empowered to restore that balance by extending the completion period, adjusting the price, or terminating the contract on fair terms. This does not override the parties' agreement, but it provides an argument that was previously available only through the restrictive doctrine of changed circumstances under the existing code. For subcontractors facing significant cost escalation on long-duration energy projects, this provision is worth understanding.

Termination for convenience. The new code introduces an express right for employers to terminate construction contracts for convenience, with the contractor entitled to fair compensation for expenses incurred and lost profit on work not yet performed. Where this flows down to the subcontract level, subcontractors have a statutory basis for recovering lost profit on termination for convenience, which was previously a matter of contract negotiation.

Decennial liability recovery. As described above, the new code expressly preserves the recovery right against subcontractors for decennial liability events but requires fault and causation to be established. This means main contractors need to ensure their subcontracts contain clear provisions on defects responsibility, insurance coverage for long-tail liability, and mechanisms for preserving evidence and claims during the decennial period.

These changes take effect on 1 June 2026. Contracts entered into before that date are generally governed by the existing Civil Code, though transitional issues may arise in ongoing disputes and long-term framework agreements.

Practical steps for subcontractors entering UAE energy projects

Before signing, a subcontractor should review the following at minimum:

• Whether the subcontract incorporates the main contract by blanket reference or selectively — blanket back-to-back incorporation is the higher-risk position
• The notice periods for claims, variations, and disputes, and whether they are shorter than the main contract upstream periods
• Whether pay-when-paid is conditioned on any event, and whether there are any carve-outs for employer insolvency or main contractor-caused non-payment
• The scope of any HSE obligations and whether a compliant safety management system is already in place before mobilisation
• Whether the liability cap is defined by reference to the subcontract price or the main contract value, and whether indemnities sit inside or outside it
• The seat and rules of any arbitration clause, and whether a subcontractor based outside Abu Dhabi or Dubai has practical access to the specified forum

For existing disputes on UAE energy subcontracts, the first question is always whether the notice obligations have been met. For guidance on FIDIC time bars and how UAE courts have treated them, see our article on FIDIC claims in the UAE.

Legal advice is required before signing an energy sector subcontract on a major ADNOC or EPC project. The risk allocation embedded in these instruments is sophisticated, the time bars are strict, and the gap between what a subcontractor expects to recover and what the contract actually allows can be very wide.
