Can grocery cashback from your weekly food shop pay off your mortgage? Not entirely, no. But we've been routing our regular shop through Sprive's cashback feature for over a year, and the numbers are starting to look surprisingly compelling. A percentage of every Tesco and Sainsbury's shop now goes directly off our mortgage balance. We didn't change what we buy. We didn't change where we shop. We just changed how we pay, and our mortgage is shrinking faster because of it.

I've used Sprive since October 2021, on a Nationwide mortgage and then, from June 2026, a Halifax one, with a monthly auto-save that started at £100. The cashback feature has been running alongside this for over a year. This post is based on real use and real numbers.
