Re-mortgage or loan for double glazing?

[DiscoStu]

The minimum term for my mortgage is about to expire (end Oct) and I really REALLY need to get my whole house double glazed. Is the best option to change my mortgage next month so that it incorporates the required costs (which will be thousands), or should I get the windows and doors on a loan/credit/buy-now-pay-later deal?

The most important thing for me is keeping my monthly outgoings as low as possible, so in that respect the remortgage makes most sense, even though I'll be repaying the windows over the life of the mortgage. Having never bought double glazing before, I am unsure of what the full price or the monthly repayments might be.

Am no financial expert but I would bet that the mortgage interest rate will be lower than any other type of loan or credit agreement.   In any case, if you check with the mortgage provider that you can make additional payments if you can afford it without  penalty, you can also reduce the length of the term and thus save additional interest costs. You may not be able to do this on any other type of loan agreement.
