On 18 May 2009, the JCT published the first in a series of revisions to its 2005 standard form building contracts and associated documents. All but its most recently revised contracts will be amended by the end of August 2009. The principal revisions comprise the incorporation of sustainability provisions and provisions that build on the Office of Government Commerce's Achieving Excellence Criteria. Aspects of the payment provisions will also be provisionally modified, pending the outcome of the proposed payment legislation. Each contract family will have a revised guide which, for the first time, will include a user checklist of key information required for completing the contract particulars.

The amended suite of contracts will still be known as the ‘2005 editions’, but also as the ‘2009 revisions’. Some contracts will be amended for the first time, rendering it technically inaccurate to refer to all the amendments as ‘Revision 2’.
