We’re Paying Off Our Mortgage with Our Food Shop Cashback. Here’s How.

Last updated: 13 October 2026

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.

Mortgage Overpayment Savings: How Much Could You Save? (2026)

Last updated: 13 October 2026

By Stiv · Design, technology and personal finance

I've overpaid my own mortgage through Sprive every month since October 2021, starting at £100 a month. This post is based on that real use and real numbers.

Most people know they should overpay their mortgage. Almost nobody knows by how much, or what it actually saves them. So we built a free mortgage overpayment calculator to find out. Then we ran our own numbers through it. The mortgage overpayment savings took us by surprise. We've since added a compare-to-savings toggle so you can see whether overpaying or saving the same money comes out ahead at your specific rates.

This article is for informational purposes only and does not constitute financial or mortgage advice. Mortgage products, rates, and overpayment terms vary by lender.

Sprive vs Plum vs Chip: Honest Comparison (2026)

Last updated: 13 October 2026

By Stiv · Design, technology and personal finance

I've used Sprive since October 2021, making monthly overpayments on my mortgage through the app. This comparison is based on that real use alongside Chip and Plum.

Sprive vs Plum vs Chip is the question that keeps coming up whenever anyone in the UK talks about saving money automatically. All three apps promise to do the hard bit for you. But they are not the same thing, and picking the wrong one means you are either missing features you need or paying for ones you do not. Here is how they actually compare after months of using all three.

Between the team, we run all three. Sprive handles mortgage overpayments. Chip is our primary auto-saver. Plum runs alongside Chip so we can see how the two compare in real life. Each has earned its place on someone's home screen, but for very different reasons.

This article is for informational purposes only and does not constitute financial advice. Some apps in this comparison offer investing features, which carry risk including the possible loss of capital. Your home may be repossessed if you do not keep up repayments on your mortgage.

This Plum app review is based on three months of hands-on use. We set up Plum to run alongside our existing auto-saver to see whether it would earn a permanent place on our home screen. Plum is one of those apps that does a lot and wants you to know it. Auto-saving, round-ups, investing, bills management, cashback offers, interest-earning pockets. After three months of testing, here's whether all that activity translates into actually saving more money.

Best Apps to Save Money UK 2026: The Ones We Actually Use

Last updated: 10 September 2026

By Stiv · Design, technology and personal finance

There are hundreds of money-saving apps in the UK app stores. Most of them are rubbish. The best apps to save money are the ones we've tested over the past few years, narrowed down and kept on our phones because they actually work. No fluff, no apps we downloaded once and forgot about. Just the ones that earned a permanent spot.

Between the team we've got about 12 money apps installed. Half of them we actually use. The other half sit there judging us. We tried about 20 apps before settling on this list. Some were too fiddly. Some had great ideas but terrible execution. A couple were brilliant but shut down. These are the survivors.

Our top money-saving pick

If you only set up one, make it Chip: it is the app that has quietly saved us the most by moving money before we miss it.

Trading 212 Review UK 2026 — Honest Verdict After 3 Months

Last updated: 8 October 2026

By Stiv · Design, technology and personal finance

This Trading 212 review reflects my own experience using the app daily to invest for three months. In the end, I moved almost all of my self-managed investing to Freetrade. I still have all the apps, but I prefer Freetrade for ease of use.

This is our honest Trading 212 review after three months of using it daily to invest. When Trading 212 kept coming up in conversations, we figured we should give it a fair shot. After using it daily for a full quarter, the verdict is clear: Trading 212 is a perfectly fine platform trapped inside a frustratingly cluttered app. The fees are competitive, the savings rate is genuinely good, but the experience of actually using it every day left me reaching for Freetrade instead. In the end, I moved almost all of my self-managed investing there. Here is why.

How Does Sprive Make Money? The Business Model Explained (2026)

If Sprive is completely free to use, how does Sprive make money? It's a fair question, and one worth asking before trusting an app with your bank account and mortgage details. The short answer: Sprive earns from remortgage commissions and a share of gift card cashback revenue. The longer answer is worth reading, because understanding the business model helps you judge whether the app's incentives actually line up with yours.

Digging into how Sprive works? Good instinct. For every guide we have written on the app, from safety to cashback, see our Sprive guides hub.

Chip Prize Saver vs Premium Bonds UK 2026: Which Is Actually Better?

Last updated: 10 September 2026

By Stiv · Design, technology and personal finance

Over 22 million people in the UK hold Premium Bonds, which makes them the nation's most popular savings product. Yet most holders have never weighed up Chip Prize Saver vs Premium Bonds side by side, and the numbers reward a closer look. Around 62% of Premium Bonds holders have never won a single prize, according to AJ Bell. The prize fund rate sits at 4.35% from the September 2026 draw, with each £1 bond facing odds of 21,000 to 1. NS&I has moved both twice this year. The rate ran at 3.30% with odds of 23,000 to 1 from April, went to 3.80% and 22,000 to 1 in July, then landed where it is now when NS&I announced the change on 18 August 2026.

Meanwhile, Chip's Prize Savings Account offers an alternative: a prize-draw savings account with a £10,000 grand prize every month and no interest at all. Both are a gamble on the return, not on the capital. You can hold either for a year, win nothing, and watch inflation eat the value of the money. We are not saying Premium Bonds are bad. Indeed, they are backed by the Treasury and pay tax-free prizes, which is a real advantage. However, if you have not compared them to anything in years, this is worth ten minutes of your time.
