Subcontractor Agreements in Ireland

Whether you're the main contractor issuing one or the subbie being asked to sign one, the subcontract decides who carries the risk on price, delay and payment. Here's what it must contain — and the clauses to read twice.

Why the subcontract matters more than the handshake

Subcontracting in Ireland runs heavily on relationships — and relationships are exactly what a good subcontract preserves. Main contractors need scope passed down "back-to-back" so a gap between the main contract and the subcontract doesn't land on them. Subcontractors need payment terms they can actually survive, because the pattern in every downturn is the same: the subbie is the bank until the subbie breaks.

What the agreement must cover

  • Scope, back-to-back but readable — the subcontract works package defined by documents, with the relevant main contract terms identified rather than incorporated wholesale by a single sentence
  • Price and valuation of variations — who can instruct changes and how they are valued (see variations)
  • Payment terms compliant with the Construction Contracts Act 2013 — payment claim dates, response deadlines and the right to refer payment disputes to adjudication cannot be contracted away where the Act applies; "pay-when-paid" clauses are ineffective except in limited insolvency situations
  • Retention — percentage, cap and release triggers (explained here)
  • Programme and delay — notice requirements for extensions of time, and any liquidated damages passed down
  • Insurance and indemnities — matched to what the subbie's policy actually covers; a subbie indemnifying the main contractor beyond their insurance is writing an uninsured cheque (see indemnities)
  • Set-off — on what grounds and with what notice the main contractor can deduct
  • Termination and site rules — including what happens to materials and plant

For subcontractors: the three clauses to never sign blind

Condition precedent notice clauses — "no notice within 7 days, no extension of time, no money" is enforceable and brutal; diary your notice obligations. Set-off clauses — an unlimited right to deduct for "any claim" converts your invoice into a suggestion. Incorporation by reference — "the subcontractor is deemed to have full knowledge of the main contract" binds you to a document you may never have seen. Ask for it. Read it.

Not being paid?

If you're a subcontractor already chasing money, the Construction Contracts Act's adjudication procedure is fast and effective. Our construction practice runs payment disputes and adjudications: constructionlawsolicitor.ie.

How our fees work

You get a fixed quote in writing before any work starts — no hourly-rate surprises and no meter running while you think. If the scope changes, the quote is revised in writing before we continue. In contentious business, a solicitor may not calculate fees or other charges as a percentage or proportion of any award or settlement. How contract solicitor fees work in Ireland →

Frequently asked questions

Is a pay-when-paid clause enforceable in Ireland?

Where the Construction Contracts Act 2013 applies, clauses making payment conditional on the payer being paid by a third party are generally ineffective, except in limited insolvency circumstances. Many subcontracts still contain them; where the Act applies, they don't do what they say.

Do I need a written subcontract for labour-only subbies?

Yes — and it needs care, because labour-only arrangements sit close to the employment/self-employment boundary, with tax (RCT), insurance and employment-rights consequences if mis-classified. A short written agreement that reflects the real arrangement protects both sides.

What retention is normal on Irish subcontracts?

Commonly in the range of 3–10% with half released at practical completion and the balance after the defects period — but there is no legal standard, and the cap and release triggers matter more than the headline percentage.

The main contractor sent 60 pages. Do I have to accept them?

Everything is negotiable until signed, and the clauses that matter to a subbie are few: payment, set-off, notices, retention, indemnity. A fixed-fee review marks up exactly those, giving you a short, credible counter-list rather than a general objection.
