JCT – Setting the standard for construction contracts


Since 1931 JCT has produced standard forms of construction contract, guidance notes, and other standard forms of documentation for use by the construction industry

Today JCT provides a larger and more comprehensive range of contract documentation than any other contract-producing body in the UK construction industry.

As a consensus organisation, JCT represents a collaboration of the major sectors of the construction industry that contribute to the contracting process.

Its members include: British Property Federation, Build UK Group Limited, Contractors Legal Grp Limited, Local Government Association, Royal Institute of British Architects, Royal Institution of Chartered Surveyors, and Scottish Building Contract Committee Limited.


About the contracts

JCT is the UK’s leading producer of standard forms of contract, which work on the principle of adapting established benchmark provisions to suit a wide range of projects.

What is a standard form of building contract?

A standard form of building contract is a form of contract containing conditions which are applicable, or can be made applicable by the use of alternatives, to a wide range of building projects.

The JCT approach

The approach is to produce standard forms that meet clearly defined needs and apportion risk in a way that is appropriate for the procurement methods they reflect. The JCT suite of contracts is made up of ‘families’ of standard forms, guidance and other documents that are suitable for the majority of construction projects and procurement methods.

JCT’s flexible and broad portfolio of main contracts, sub-contracts, agreements, warranties, and other documents ensures that our contracts support a wide range of construction activity, including complex, large-scale projects, right through to individual home owners carrying out alterations.

Subscription service with advanced editing and drafting features

JCT Construct banner - Stakeholder position 2021

JCT Construct is a subscription-based contract drafting system with advanced editing features. The service enables you to create, amend, and customise the drafting of your JCT contracts in a secure, flexible, and easy to use online environment.

With JCT Construct’s powerful tools you can edit the JCT contract text itself, adding your own amendments, clauses, or other customised text. This is alongside being able to use the same intuitive Q&A process as JCT On Demand to fill in your contract comprehensively.

The JCT Construct system generates your contract in plain copy as well as a comparison document, making it possible to easily read the contracts and see all your added changes tracked against the published JCT text.

Guest sharing supports collaborative working among those involved in the contract drafting to share drafts, to edit, and to see all the changes. Version-to-version comparison allows you to see any of your or your guest collaborators’ changes between draft versions and against the published JCT text, ensuring full transparency between the parties to the contract at all times.

Two subscription options of JCT Construct, ‘JCT Construct – Complete’ or ‘JCT Construct – Small Works’ grant digital access to either the full, or limited, range of the JCT 2016 Edition of contracts. There are also various options depending on how many users you or your company would like to include under your subscription licence.
