Depends on which is costing more, savings to be made if loan is paid off, less two months payments, (just for final settlement terms), or interest payable on the ISA.
It has to be your choice, as you have the figures, but as most ISA's pay about a max of 3-3.6%, I'd get rid of loan, then pay your loan payments into your ISA, which would boost your ISA.
This would be because you have been paying your loan, and (not?) really having too adverse an effect on your household, then by continuing with this tack, you'll still be saving for the rainy day as well.
