What statutory rights does the HGCRA 1996 give to contractors in England and Wales?

The Housing Grants, Construction and Regeneration Act 1996 (HGCRA 1996), as amended by the Local Democracy, Economic Development and Construction Act 2009, gives contractors in England and Wales three fundamental statutory rights. First, the right to receive payment: the Act requires every construction contract to include an adequate mechanism for determining what payments become due and when, the final date for payment, and the obligation to issue Payment Notices within a specified period. Second, the right to suspend: under section 112, a contractor who has not been paid by the final date for payment (and has not received a valid Pay Less Notice) may, after 7 days' written notice, suspend performance of any or all contractual obligations. The period of suspension does not count towards the contractor's contractual time obligations and the contractor is entitled to its reasonable costs of suspension and resumption. Third, the right to adjudicate: under section 108, either party to a construction contract has the right to refer any dispute to adjudication at any time. An adjudicator must be appointed within 7 days and reach a decision within 28 days of the referral. The decision is binding immediately, even if later challenged by arbitration or court proceedings. If a construction contract does not comply with these provisions, the Scheme for Construction Contracts (England and Wales) Regulations 1998 is implied by statute to fill the gaps.

What is the Construction Industry Scheme (CIS) and how does it affect payments under a construction contract?

The Construction Industry Scheme (CIS) is a HMRC tax scheme that applies to payments made by contractors (within the CIS definition) to subcontractors for construction work. Under the scheme, contractors are required to deduct CIS tax from payments to subcontractors who are not registered as gross payment status holders. The CIS deduction rate is 20% for registered subcontractors and 30% for unregistered ones. A construction contract between two CIS-registered businesses should address how CIS applies to the contract sum — specifically, whether the stated price is inclusive of or exclusive of CIS deductions, and what documentation (including monthly CIS statements) the paying party must provide. CIS deductions are not a tax on the subcontractor's profit — they are advance payments of income tax and National Insurance that the subcontractor can offset against their final tax liability. Contractors who fail to operate CIS correctly can face penalties from HMRC. The CIS regime applies to construction operations as defined in section 74 of the Finance Act 2004, which is broadly similar to the HGCRA 1996 definition of construction operations.

How are liquidated damages set and enforced under English construction law?

Liquidated damages (LDs) are a pre-agreed sum payable by the contractor for each day or week of culpable delay in achieving practical completion. Under the principles confirmed by the Supreme Court in Cavendish Square Holding BV v Makdessi [2015] UKSC 67, liquidated damages provisions are enforceable if they represent a genuine pre-estimate of loss or are commercially justifiable as protecting a legitimate interest — they need not be a precise arithmetical calculation and will not be struck down merely because they exceed the actual loss. To set an appropriate LD rate, the employer should document the losses it reasonably anticipates from delay — for example, lost rental income, additional financing costs, costs of alternative accommodation, or business interruption — and set the rate at or below that level. To enforce LDs, the employer must have issued a written notice of intention to deduct, and the contractor must be in culpable (i.e., contractor-risk) delay — LDs are not payable for delay caused by the employer, by instructed variations, or by events for which an extension of time has been granted. A clause providing for LDs that are wholly out of proportion to any conceivable legitimate interest remains potentially challengeable as a penalty under English law.

What is the difference between assignment and subcontracting in a UK construction contract?

Assignment and subcontracting are conceptually distinct under English contract law, although both involve a third party in the performance of the contract. Assignment is the transfer of contractual rights (such as the right to receive payment) from one party to another. The assignment of contractual obligations (burdens) requires a novation — the substitution of a new contract between the original parties and the new party. Most construction contracts prohibit assignment of the benefit or burden of the contract without consent, because the identity of the contracting party matters (the employer is contracting for the specific contractor's skill and experience; the contractor has priced the project on the basis of the employer's covenant strength). Subcontracting is the engagement of a third party (a subcontractor) to perform part of the works that the contractor has agreed to carry out. Unlike assignment, subcontracting does not transfer contractual liability — the contractor remains liable to the employer for the subcontractor's performance as if it had done the work itself. Most construction contracts permit subcontracting of nominated trades (mechanical and electrical, specialist groundworks, etc.) with the employer's consent, while prohibiting wholesale subcontracting of the entire works.

What is practical completion and why does it matter in a UK construction contract?

Practical completion is the point at which the works are sufficiently complete for the employer to take possession and use them for their intended purpose, even if minor outstanding items (a 'snagging list') remain. The legal test for practical completion in England and Wales — confirmed in Mears Civil and Construction Ltd v Samuel Williams (Dagenham Dock) Ltd [2024] EWHC 347 (TCC) and earlier decisions — is whether the works are complete for all practical purposes, with only trivial or de minimis items outstanding. Practical completion has significant legal consequences under a construction contract: liquidated damages for delay stop accruing; the defects liability period begins; one-half of the retention fund is typically released; the contractor's obligation to insure the works transfers to the employer; and the limitation period for bringing a breach of contract claim begins to run. For higher-risk buildings under the Building Safety Act 2022, completion of the construction phase is also a regulatory gateway point requiring the Building Safety Regulator's approval before the building can be occupied. Disputed practical completion is one of the most common causes of litigation in the Technology and Construction Court.

General Construction Contract (UK) — United Kingdom

Create a comprehensive General Construction Contract for England and Wales. Compliant with the Housing Grants, Construction and Regeneration Act 1996 (payment notices, right to suspend, adjudication), CDM 2015 Principal Contractor duties, Building Safety Act 2022, and Defective Premises Act 1972. Covers commercial and residential construction projects with liquidated damages, retention, professional indemnity, and HGCRA-compliant payment terms.

What Is a General Construction Contract (UK)?

A General Construction Contract is a legally binding agreement between an employer (the party commissioning the works) and a contractor (the construction company or individual carrying out the works) for the execution of a construction project in England and Wales. Unlike the more familiar domestic building contract for small residential extensions, a general construction contract is typically used for larger, more complex commercial, industrial, or mixed-use projects — including new build developments, commercial fit-outs, civil engineering projects, and major refurbishments.

Construction contracts in England and Wales are subject to a distinctive and extensive body of legislation that distinguishes them from ordinary commercial contracts. The most important statute is the Housing Grants, Construction and Regeneration Act 1996 (HGCRA 1996), as amended by the Local Democracy, Economic Development and Construction Act 2009. The HGCRA 1996 implies mandatory payment and adjudication rights into any construction contract as defined by the Act, regardless of what the parties' written contract says. Key requirements include: a mechanism for determining what payments are due and when (including Payment Notices and Pay Less Notices); a right for the contractor to suspend work after 7 days' written notice if an undisputed payment is not made; and the right for either party to refer any dispute to adjudication at any time and receive a decision within 28 days.

The Construction (Design and Management) Regulations 2015 (CDM 2015) impose health and safety management obligations on all parties involved in a construction project — including the client, principal designer, principal contractor, designers, and contractors. For projects involving more than one contractor, the client must appoint a Principal Designer and a Principal Contractor in writing before the construction phase begins. Failure to comply with CDM 2015 can expose all parties to enforcement action by the Health and Safety Executive.

The Building Safety Act 2022 introduced comprehensive reforms to building safety regulation, particularly for higher-risk buildings (broadly, residential buildings over 18 metres or 7 storeys). The Act extended the limitation period under the Defective Premises Act 1972 from 6 to 15 years, introduced new dutyholder roles with golden thread information obligations, and created mandatory regulatory gateways at key stages of the design and construction process. All construction contracts for projects in England and Wales should now address Building Safety Act 2022 compliance obligations.

The standard forms of construction contract widely used in England and Wales — notably the JCT (Joint Contracts Tribunal) suite, the NEC Engineering and Construction Contract, and the FIDIC suite for international projects — all incorporate these statutory requirements. Our General Construction Contract template provides a comprehensive, legally compliant framework suitable for commercial and residential construction projects, incorporating the mandatory payment and adjudication provisions required by the HGCRA 1996, CDM 2015 obligations, and Building Safety Act 2022 compliance duties.

When Do You Need a General Construction Contract (UK)?

A General Construction Contract is needed whenever a significant construction project is being commissioned in England and Wales. This template is particularly suited to the following circumstances.

Commercial construction projects: When a developer, property company, or business entity is procuring the construction or fit-out of commercial premises, including offices, warehouses, retail units, hospitality venues, or industrial buildings. A detailed written contract is essential to manage the risks associated with large-scale construction, including cost overruns, programme delays, defective work, and insolvency of the contractor.

Residential development projects: When a developer is commissioning the construction of new residential dwellings — whether a single house or a multi-unit development — the contract must comply with the HGCRA 1996, the Defective Premises Act 1972, and (for higher-risk buildings) the Building Safety Act 2022. The extended limitation periods under the 2022 Act make a carefully drafted contract with appropriate insurance provisions essential.

Mixed-use developments: When a project involves a combination of residential and commercial uses, the contract must address the different regulatory requirements applying to each part, including building regulations, planning conditions, and the Building Safety Act 2022 regime for any residential element over 18 metres.

Design-and-build projects: When the contractor is responsible for both the design and construction of the works, the contract must address professional indemnity insurance, design liability, fitness for purpose obligations, and the interaction between the contractor's design obligations and the employer's employer's requirements.

Refurbishment and fit-out projects: When an existing building is being significantly altered, extended, or fitted out for a new use, a general construction contract governs the relationship between the building owner and the main contractor, setting out the works to be carried out, the price, the programme, and the parties' respective obligations.

Projects with multiple subcontractors: CDM 2015 requires a Principal Contractor to be appointed wherever there is more than one contractor on site. The general construction contract between the employer and main contractor should therefore include provisions addressing the appointment and duties of the main contractor as Principal Contractor.

What to Include in Your General Construction Contract (UK)

A well-drafted General Construction Contract for use in England and Wales must address a series of key provisions that together provide a legally compliant and commercially balanced framework for the project.

HGCRA 1996-Compliant Payment Provisions: The contract must specify the mechanism for determining what payments are due and when — typically monthly interim valuations — the date by which the Payment Notice must be issued, and the final date for payment. It must also provide for the issue of a Pay Less Notice if the employer intends to pay less than the notified sum. The right to suspend work for non-payment and the entitlement to interest on late payments must be expressly included or will be implied by the HGCRA 1996.

Liquidated Damages: The contract should specify the rate of liquidated damages payable by the contractor for each week of culpable delay in achieving practical completion. The rate must represent a genuine pre-estimate of the employer's likely losses. The contract must also provide an extension of time mechanism that gives the contractor relief from liquidated damages where delay is caused by employer risk events, to preserve the employer's right to deduct liquidated damages.

Retention Fund: Retention is a widely used security mechanism in commercial construction. The contract should specify the retention percentage, the conditions for release at practical completion and at the end of the defects liability period, and whether the retention is to be held in a separate trust account (increasingly required by industry guidance following contractor insolvencies).

Defects Liability Period: The contract should specify the duration of the defects liability period (typically 12 months for commercial projects), the procedure for notifying defects, and the contractor's obligation to make good within a reasonable time. The contract should also address liability for latent defects under the Limitation Act 1980 and the extended limitation periods under the Building Safety Act 2022.

Insurance Requirements: The contractor should be required to maintain adequate public liability insurance, employers' liability insurance, and contractors' all risks insurance throughout the project. Where the contractor has design responsibility, professional indemnity insurance should also be required, maintained for a period of 6 or 12 years (depending on whether the contract is executed as a deed) after practical completion.

Adjudication and Governing Law: The contract must comply with section 108 of the HGCRA 1996 by giving either party the right to refer any dispute to adjudication at any time. The nominating body for the adjudicator should be specified. The governing law and jurisdiction should be stated as England and Wales.
