Choosing between JCT and NEC contracts
Choosing the right building contract is one of the most important early decisions on any construction project. The two main families of standard contracts used in the UK are JCT (Joint Contracts Tribunal) and NEC (New Engineering Contract). JCT forms such as the JCT Design and Build Contract, Standard Building Contract and Minor Works are common on private sector building projects, while NEC4 ECC, including Option A (priced contract) and Option C (target cost), is widely used for public sector and infrastructure work.
As RICS-regulated contract administrators, Employer’s Agents and NEC Project Managers based in Birmingham, we help clients across the West Midlands and the UK choose, set up and run the right contract.
Frequently asked questions
What is the difference between JCT and NEC?
JCT contracts set out the rights and obligations of each party in a more traditional way, with a contract administrator or Employer’s Agent acting for the client. NEC contracts are built around proactive, collaborative management, with early warnings, an accepted programme and strict time limits for notifying and assessing change.
Which contract is best for design and build?
On private sector building projects, the JCT Design and Build Contract is the most common choice. NEC4 Option A can also be used with the contractor responsible for design, and is often preferred by public sector clients.
Is NEC Option A or Option C better?
Option A gives a fixed price and suits well-defined work where price certainty matters. Option C uses a target cost with shared savings or overruns, and suits complex or uncertain work where collaboration matters more than a fixed price.
