Final Payment Certificate #3 is not updating payment due to contactor figure is showing as £0.00? Previous payment amount has not been deducted from Final payment. what should have happened so far is valuation 1 & 2 should have been interim valuations and #3 (the valuation you are producing now), should be the penultimate valuation. The final valuation is for releasing retention, which you do not have, and is why the certificate shows £0.00. Because you have already produced 1 penultimate certificate it may prevent you from producing another one. Request the following: - Change valuation #2 from penultimate to interim (this won't change the certificate in any way, other than it will be titled "Interim" rather than "penultimate" - Remove valuation #3 (Final Payment Certificate) Once this has been done you will then be able to generate a penultimate valuation and you should find the figures come out as expected
