Contract variations must be in writing

It is essential that you, as a contractor, properly document all variations.

Correct documentation of variations will help ensure you are paid for the work that you are being asked to do.

It will also help you avoid possible compliance action and costly disputes if there is any disagreement arising from changes to the work you have been contracted to carry out.

The variation documentation must:

  • describe and price the variation
  • give a reasonable estimate of any delay the variation may cause to the completion date
  • be dated and signed by you
  • be copied to the owner within five business days of agreement on the variation.

You cannot claim extra payment for a variation unless the owner has already agreed to it in writing and the variation work has commenced.
