Getting Security of Payments Right
Subcontractors often come to us at the eleventh hour for help when they haven’t been paid, but there are some common pitfalls that can put the benefit of the Security of Payments Act out of their reach. In this article I have summarised some of the most frequent problems encountered.


For work done or supplies made subject to a contract entered into on or after 21 October 2019, the Payment Claim must include an endorsement stating that it is a Payment Claim made under the Building and Construction Industry Security of Payments Act 1999 or words to that effect.
The description of the work appearing on the Payment Claim should be sufficiently clear to allow the recipient to identify what work is being claimed for.
Payment Claims may only be made;
- on or after the last day of the month in which work was done unless an earlier date is provided by the Contract; and
- within 12 months after the construction work claimed was last carried out unless the Contract provides for an earlier date(s).
There is an exception to the above if the Contract has been terminated, in which case a Payment Claim can be made on or from the day of termination.
Only one Payment Claim may be made in any given calendar month unless the Contract expressly provides otherwise. The effect of submitting multiple Payment Claims in a single calendar month absent a contractual entitlement to do so will be to render all but the first Payment Claim made in that month invalid for the purposes of the Act.
A common pitfall is made by Claimants that submit separate Payment Claims for contract scope works and variations respectively.
