Contracts are the backbone of successful construction projects, defining the roles, responsibilities, and risks involved. Choosing the right contract and understanding its terms is crucial for clients, contractors, and subcontractors alike. The Joint Contracts Tribunal (JCT) and the New Engineering Contract (NEC) are two of the most widely used contracts in the UK construction industry.
The JCT, with its latest edition released in 2024, is traditionally seen as a comprehensive and widely accepted contract for building projects in the UK. On the other hand, with its most recent version of NEC4 introduced in 2017, NEC is becoming ever more popular and is known for its collaborative and flexible approach, making it suitable for domestic and international projects.
In this article, we’ll explore the nuances of these contracts, compare their features, including what you need to be aware of, and help you determine which might be best suited for your project needs.

What is a JCT Contract?
Background: The Joint Contracts Tribunal (JCT) was established in 1931 to standardise procurement processes for the UK construction industry. It is considered a traditional contract and has been widely adopted across various types of building projects.
Purpose: JCT contracts are designed to standardise and simplify the procurement process, covering a wide range of procurement options, including traditional, design and build, minor works, and more.
Latest Editions: The most recent edition is the 2024 edition, though the 2016 edition remains commonly used.
Approach: JCT contracts focus on allocating risk and assessing compensation but often lack proactive conflict management procedures.
Key Features:
Roles and Responsibilities: Managed by a Contract Administrator (CA) or Employer’s Agent (EA), who oversees project administration, inspections, and certification.
Pricing Structures: Typically uses fixed-price lump sum contracts, though remeasurement and prime cost contracts are also available.

Purpose: NEC aims to foster a collaborative approach between contractors and employers (or contractors and subcontractors), focusing on proactive management and flexibility.
Latest Editions: The latest version, NEC4, was published in 2017, with supplements issued later.
Approach: NEC contracts emphasise collaboration and early risk management, with a structured approach to addressing issues as they arise.

Key Differences Between JCT and NEC Contracts
Now you have a greater understanding of JCT and NEC, here are some of the key differences between both contracts:

NEC: Encourages collaborative risk management with early warning procedures and proactive issue resolution.
Payment Procedures
JCT: Payment terms are straightforward but may be less flexible in addressing changes.

When to Use Each Contract
JCT Contracts: Best suited for projects where a traditional approach is preferred, with clear risk allocation and control over project delivery. Ideal for domestic, commercial developments and projects requiring straightforward contractual terms.
NEC Contracts: Ideal for complex, large-scale projects requiring flexibility, collaboration, and proactive risk management. It is particularly effective for international projects and public sector frameworks where adaptability and teamwork are crucial.
