If you want to squeeze more value out of every Amazon UK order, this Amazon UK cashback method is worth knowing about. The idea is simple: instead of buying directly from Amazon, you buy Amazon gift cards through the Sprive app, earn cashback on each card, and then funnel that cashback straight into your mortgage. Over time, those small percentages quietly chip away at your balance and interest. Combine it with a spending tracker like Emma to see exactly where your money goes, and you have a system that turns routine shopping into purposeful saving.

This is not financial advice. Always check your mortgage terms before making overpayments.

How to set up the Amazon UK cashback method

Step 1: Track your Amazon spending with Emma

First, download the Emma app and link your bank accounts. Emma uses Open Banking and is registered with the FCA (Emma Technologies Ltd, FRN 794952) to give you a clear breakdown of your outgoings. This way you can see exactly how much you spend on Amazon each month. That figure becomes your baseline. For example, if you typically spend around £200 a month on Amazon, that is the amount you will want to pre-load as gift cards through Sprive.

Step 2: Sign up to Sprive

Sprive is a free UK mortgage overpayment app that lets you earn cashback by buying gift cards for popular retailers. When you purchase an Amazon gift card through the app, Sprive credits a percentage of the value to your mortgage pot. You can then send that cashback directly to your mortgage lender as an overpayment. Sprive Limited is an appointed representative of Connect IFA Ltd (FRN 441505), which is authorised and regulated by the FCA. You can also use our referral code LM125CR6 when signing up, or sign up via our referral link for any current welcome offer.

Step 3: Buy Amazon gift cards through Sprive

Rather than paying Amazon directly, buy gift cards for the amount you plan to spend. Once purchased, add the gift card to your Amazon account and shop as normal. Meanwhile, your cashback sits in Sprive ready to go toward your mortgage. This small change in habit is where the Amazon UK cashback method starts working for you.

Step 4: Overpay your mortgage

As your cashback builds up in Sprive, you can send it to your mortgage lender with a single tap. Most UK lenders allow overpayments of up to 10% of the outstanding balance per year without penalty, although you should always double-check your own terms. According to MoneyHelper, even modest overpayments can reduce both the total interest you pay and the length of your mortgage. Your home may be repossessed if you do not keep up repayments on your mortgage.

How much could you save with Amazon UK cashback?

Sprive's cashback rates vary by retailer. Amazon gift cards currently earn around 1% cashback via Sprive, while other brands can offer higher rates. Here is what that looks like in practice at current rates:

£200/month on Amazon at 1% cashback: That is £2 a month, or £24 a year. Over ten years, you would earn £240 in cashback, all redirected to your mortgage.
£500/month at 1% cashback: That adds up to £5 a month, £60 a year, and £600 over a decade.
£800/month at 1% cashback: Roughly £8 a month, £96 a year, and £960 across ten years.

These numbers look modest on their own. However, once applied as mortgage overpayments, they benefit from compound interest savings. For instance, putting an extra £96 a year toward a £250,000 mortgage at 4% interest over 25 years could save you around £1,500 in interest and shorten your term by several months. This is an illustration only, not a projection; your outcome will depend on your specific mortgage terms.

Note: the 1% Amazon cashback rate is current at the time of writing and could change. Sprive's cashback rates are set by the retailers. Always check the app for the current rate before buying gift cards.

Why the Amazon UK cashback method works

The appeal of this approach is that you are not spending any extra money. You are simply redirecting spend you would make anyway and capturing a small return on it. Additionally, because the cashback goes toward your mortgage rather than sitting in a random loyalty scheme, it has a real, measurable financial impact.

There are a few reasons this strategy may suit UK homeowners:

No lifestyle change required. You shop on Amazon as normal. The only difference is buying a gift card first.
Visibility through Emma. Tracking your Amazon spend gives you control and stops cashback-chasing from turning into overspending.
Compound benefit. Each overpayment reduces your outstanding balance, which in turn reduces the interest charged on future payments.
Stackable. You can buy gift cards for other retailers through Sprive too, so your Amazon UK cashback becomes just one part of a wider approach.

Important things to know before you start

Before diving in, there are a few caveats worth considering. First, check whether your mortgage allows overpayments and whether there are any early repayment charges, especially if you are on a fixed-rate deal. Second, the 1% Amazon cashback rate is current at the time of writing but could change. Third, do not let the prospect of earning cashback tempt you into spending more on Amazon than you normally would. The whole point of this method is to make existing spending work harder, not to create new spending.

Finally, linking bank accounts to apps like Emma and Sprive requires Open Banking permissions. Both apps use read-only, encrypted connections and are regulated in the UK.

Can I overpay my mortgage with cashback from Sprive?

Yes. Sprive is designed specifically for this purpose. Once your cashback builds up, you can send it directly to your mortgage lender through the app. Make sure your mortgage allows overpayments and check for any annual limits or charges. Your home may be repossessed if you do not keep up repayments on your mortgage.

Is this actually worth the effort?

If you already shop on Amazon regularly, the extra effort is minimal. You are simply buying a gift card before you shop. Over several years, even small cashback amounts compound into meaningful mortgage savings. For instance, £96 a year in overpayments on a typical UK mortgage could save over £1,500 in interest (illustration only; actual savings will vary).
