Subcontracting Notice

A Subcontracting Notice is used by a main contractor who has been awarded a public contract and wants to openly advertise for subcontractors to deliver part of that work. Unlike most other notice types, which are published by contracting authorities (buyers), a Subcontracting Notice is published by a commercial entity (the main contractor) that has already won public work and is now acting as a private purchaser seeking its own supply chain.

What is a Subcontracting Notice?

When a main contractor wins a significant public contract, it will often need to subcontract portions of the work to specialist suppliers. In many European countries and sectors, there is growing policy and contractual pressure to open these subcontracting opportunities to competition, particularly to smaller businesses that may not have the scale or resources to bid directly on the main contract.

A Subcontracting Notice published on TED or a national procurement portal signals to the supplier market that subcontract opportunities are available under a named public contract. It typically sets out the work package being subcontracted, the required qualifications and experience, the estimated value, and the process for expressing interest.

Subcontracting Notices are not universally mandated by EU directives in the same way as Contract Notices. Their use varies by sector, country, and contractual arrangement. In defence procurement under Directive 2009/81/EC, there are specific provisions encouraging the advertising of subcontract opportunities by prime contractors receiving public defence contracts, reflecting the policy goal of broadening the defence industrial base across Europe.

Under eForms, the Subcontracting Notice is one of the defined notice subtypes, though its use is more discretionary than mandatory notice types. The eForms SDK provides a structure for those who choose to publish such notices on TED.

Why Subcontracting Notices matter for bidders

For small and medium-sized enterprises (SMEs) and specialist subcontractors, Subcontracting Notices represent an important route into public contract value that bypasses the barriers of prime contracting. Bidding directly on a EUR 50 million infrastructure contract may be beyond a small specialist firm's capacity, but bidding for a EUR 3 million specialist subcontract package within that same project may be well within reach.

Monitoring Subcontracting Notices allows specialist firms to: identify which prime contractors are winning work in their target sectors; understand what subcontract packages are being competed; and build relationships with primes that could lead to preferred subcontractor status on future bids. Some primes advertise subcontract opportunities selectively rather than openly, so responding quickly to Subcontracting Notices when they are published demonstrates market engagement.

Example

A German construction company wins a EUR 120 million public hospital construction contract. It publishes a Subcontracting Notice inviting expressions of interest from specialist MEP (mechanical, electrical, and plumbing) contractors for a EUR 15 million installation package. The notice sets out the technical requirements, the programme, and the minimum financial standing expected from subcontract applicants. Twenty SMEs respond, and the prime shortlists five for detailed bid submissions.

Frequently Asked Questions

Is a main contractor obligated to publish a Subcontracting Notice?

Not always. The obligation varies by country, contract terms, and sector. In some EU member states and for certain contract types (particularly in defence), advertising subcontract opportunities is required or strongly encouraged. In commercial sectors, it is often voluntary but may be required by the terms of the main contract with the public authority.

Can I use a Subcontracting Notice to find consortium opportunities before the main bid is submitted?

A Subcontracting Notice is published post-award. For pre-bid consortium formation, you would typically look for market engagement events, prior information notices, or direct outreach to bidding consortia before the main tender closes.

Are Subcontracting Notices published on TED?

Some are, using the eForms format. Others are published on national procurement portals, sector-specific tender platforms, or through direct outreach by the main contractor. Coverage on TED is not comprehensive, so monitoring multiple channels is advisable.
