The Sub-Contract Works shall be carried out in accordance with any drawings, specifications, method statements and programmes agreed in writing between the parties and in conformity with the Main Contract insofar as its provisions are applicable to the Sub-Contract Works. A copy of the relevant extracts of the Main Contract has been made available to the Subcontractor.
Completion: The Subcontractor shall use all reasonable endeavours to achieve practical completion of the Sub-Contract Works on or about 29 May 2026.
Access and Site Conditions: Monday-Friday 07:30-17:30. Saturday 08:00-13:00 with 48h prior notice. CSCS cards mandatory. Site induction by PC's site manager on first day. Welfare facilities and 110v site supply provided by Contractor.
The Contractor shall provide the Subcontractor with reasonable and unobstructed access to the relevant parts of the Site at the times agreed. Where delay is caused by an act or omission of the Contractor, or by any other matter beyond the Subcontractor's reasonable control, the Subcontractor shall be entitled to a fair and reasonable extension of time to the completion date.
Due date (s.109 HGCRA): Each interim and final application for payment shall have a due date of the date of receipt by the Contractor.
Payment notices (s.110A HGCRA): Not later than five days after the due date, the Contractor shall give a payment notice specifying the sum the Contractor considers due and the basis of calculation. Where the Contractor fails to give such notice, the sum notified in the Subcontractor's application shall become the notified sum (s.110B default payment notice).
Final date for payment (s.110 HGCRA): The final date for payment of each notified sum is 30 days after the due date.
Pay-less notice (s.111 HGCRA): If the Contractor intends to pay less than the notified sum, the Contractor shall give a written pay-less notice not later than 7 days before the final date for payment, specifying the sum the Contractor considers due and the basis of calculation. In the absence of a compliant pay-less notice, the Contractor shall pay the notified sum in full.
Suspension for non-payment (s.112 HGCRA): If any notified sum is not paid in full by the final date for payment and no valid pay-less notice has been served, the Subcontractor may, on seven days' written notice, suspend performance of any or all of its obligations until payment is made, with an entitlement to an extension of time and reasonable costs (s.112(3A)).
Pay-when-paid prohibited (s.113 HGCRA): Any provision making payment conditional on the Contractor being paid under the Main Contract is ineffective, save where the third-party payer is insolvent as defined in s.113(2)-(4).
Late-payment interest (Late Payment Act 1998): Without prejudice to any other remedy, any sum not paid by the final date for payment shall bear interest at 8% above the Bank of England reference rate, together with the fixed sum and reasonable recovery costs permitted by section 5A of the Late Payment of Commercial Debts (Interest) Act 1998.
Retention: The Contractor shall be entitled to deduct 5% from each payment due to the Subcontractor. Half of the Retention shall be released within 14 days of practical completion of the Sub-Contract Works and the remaining half within 14 days of the end of the Defects Liability Period under Clause 6, subject to the satisfactory making good of any defects.
The Subcontractor shall provide the Contractor with its Unique Taxpayer Reference (UTR), National Insurance number (sole traders) or company number on request, together with evidence of CIS registration status. The Contractor shall issue the Subcontractor with a monthly payment and deduction statement as required by the Income Tax (Construction Industry Scheme) Regulations 2005 reg.4.
The Subcontractor shall cooperate with the Principal Designer and Principal Contractor appointed under the Main Contract, provide such information as they reasonably require, and comply with the construction phase plan. The Subcontractor shall notify the Contractor immediately of any accident, dangerous occurrence or near-miss required to be reported under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR).
The Subcontractor warrants that it has the right to work in the United Kingdom (Immigration, Asylum and Nationality Act 2006) and shall indemnify the Contractor against any liability to HMRC arising from a misrepresentation of its tax or immigration status.
(b) Amendments: No amendment to this Agreement shall be effective unless made in writing and signed by or on behalf of both parties.
(c) Severability: If any provision is held to be invalid or unenforceable, the remaining provisions shall continue in full force and effect.
(d) No partnership: Nothing in this Agreement shall constitute a partnership, joint venture or agency between the parties.
(e) Third-party rights: A person who is not a party to this Agreement has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any of its terms.
(f) Notices: Notices shall be in writing and served at the address given on the first page, by hand, first-class post or email (with confirmation of receipt). Service provisions comply with s.115 HGCRA 1996.
What Is a Subcontractor Agreement?
A subcontractor agreement is a contract between a main contractor and a subcontractor for the performance of specific works or services forming part of a wider construction project. It defines the scope of the subcontract works, the price, the programme and the relationship between the parties.
In the UK construction industry, subcontracting is the norm. Main contractors engage specialist subcontractors for trades such as electrical, plumbing, plastering, roofing, steelwork and groundworks. A formal agreement ensures both parties understand their obligations and protects against disputes.
UK subcontractor agreements in England and Wales must comply with the Housing Grants, Construction and Regeneration Act 1996 (as amended), which provides statutory rights to interim payments and adjudication. The British agreement should also address CIS (Construction Industry Scheme) tax deduction requirements under English law.

Reviewed for England & Wales law
Construction Act Compliance
The UK Housing Grants, Construction and Regeneration Act 1996 applies to subcontracts for construction operations in England and Wales. It requires an adequate payment mechanism with defined due dates, payment notices, pay less notices and the right to suspend for non-payment. British subcontractors also have the right to refer disputes to adjudication at any time.
Construction Industry Scheme
The UK CIS requires British main contractors to deduct tax from payments to subcontractors unless the subcontractor holds gross payment status. The standard deduction rate is 20% for registered subcontractors and 30% for unregistered subcontractors in England and Wales. The main contractor must verify CIS status with HMRC before making payments.
Employment Status
The UK agreement should reflect a genuine self-employment relationship. If HMRC determines the British subcontractor is actually an employee, the main contractor may be liable for PAYE, National Insurance and penalties under English law. IR35 rules and the UK employment status tests should be considered.
CDM Regulations 2015
The UK Construction (Design and Management) Regulations 2015 impose duties on British contractors and subcontractors. Subcontractors in England and Wales must plan, manage and monitor their work to ensure health and safety, cooperate with the principal contractor and comply with UK site rules.
