@neilinvests: AD | How to reduce the amount of interest you pay on your mortgage for free. Sprive gives you cashback on your everyday spending, which you can then use to overpay your mortgage. Over time, that can reduce the amount of interest you pay and help you become mortgage free sooner. Supercharged Rewards are personal to you, depending on your mortgage and purchase amount, and are calculated by how much you'd save in mortgage interest on the cashback you earn. Sprive is a free app. Your home may be repossessed if you do not keep up repayments on your mortgage.
