It is highly unlikely that the installation will pass inspection without a GFCI. Installing a GFCI is not a big deal and ought not be a significant expense for you as the contractor. The licensed electrician you typically use on spa installations and repairs ought to be able to install a GFCI at nominal additional cost to you.You might want to have a discussion with the estimator who gave the quote on behalf of your company. The absence of a GFCI is not an unforeseeable issue. Any time a contractor gives a quote for work, the contractor needs to inspect the current installation to determine if there is work required to bring the item "up to Code." This is a common requirement for passing inspection. Building Codes are constantly updated. While GFCI requirements were updated in 2023, the requirement of hard-wiring a hot tub or spa to an outlet that is GFCI protected has been around for many years now.So I think you would lose on the argument about the GFCI being unforeseen or unanticipated at the time of the quote. Some contractors, however, specifically include language in theri quotes that the customer will be responsible for the cost of any additional work required to bring the installation up to Code in order to secure a permit or pass inspection.
