To protect your position as owner, we recommend at a minimum that the contract is checked and amended in two ways. Firstly, the progress payments should only be enough to cover the work that had been completed up to the date of that payment. Secondly, the final payment should not be paid until after the Council has issued their CCC. This is because the final inspection can determine that more work is required before the CCC is provided. If your builder has already been paid in full, they can be reluctant (or slow) in completing that final work for you.
