Looking for the best mortgage overpayment apps in the UK? Whether you want an app that automates everything, a savings tool that builds your overpayment pot, or a budgeting app that finds spare cash you didn't know you had, there are more options in 2026 than ever. I've tested and compared the main contenders so you can find the right one for how you actually manage money.

Why use a mortgage overpayment app?

Most UK lenders allow you to overpay up to 10% of your outstanding balance each year without penalty, though the FCA notes that Early Repayment Charges vary by product. The maths is clear: even small, regular overpayments can shave years off your term and save thousands in interest. The problem is not understanding that. The problem is actually doing it, consistently, month after month, for years on end.

That's where mortgage overpayment apps come in. Some automate the whole process. Others help you build up a pot of cash to send as a lump sum. And a few are not mortgage apps at all but are useful at freeing up the money you need to overpay in the first place. I've grouped them by what they actually do, so you can find the right fit.

If you want the bigger strategy behind all of this, our how to pay off your mortgage faster guide covers the full picture. This post is specifically about the tools.

Sprive: purpose-built for mortgage overpayments

Sprive is the only UK app built specifically around mortgage overpayments, which is why it leads this list. It connects to your bank via Open Banking, analyses your spending, and sets aside small amounts you can afford based on limits you control. When you're ready, you can send overpayments to your lender directly through the app.

Sprive is free to use and is regulated via an appointed representative arrangement: Sprive Limited (FRN 919863) is an appointed representative of Connect IFA Ltd (FRN 441505), authorised and regulated by the Financial Conduct Authority. According to Sprive's FAQ, the app currently supports 14 of the largest UK lenders, including Nationwide, Halifax, HSBC, Barclays, Lloyds, NatWest, Santander, RBS, Virgin Money, TSB, Yorkshire Building Society, Coventry Building Society, Accord Mortgages, and First Direct. If your lender is not listed, you can still use the autosaving feature and transfer money to your lender manually.

Cashback on top of autosaving

On top of autosaving, there's a cashback feature called Shop with Sprive. You buy digital gift cards for over 1,000 retailers including Tesco, Amazon, M&S, ASDA, and Sainsbury's, and the cashback percentage goes into your mortgage overpayment pot. Cashback rates typically range from around 1% to 4% depending on the retailer. It's not going to clear your mortgage on its own, but it's a useful way to accelerate things without spending extra.

Among all mortgage overpayment apps in the UK, Sprive is the only one that handles the entire journey: from saving, to cashback, to sending the payment directly to your lender. Sprive appeared on BBC Dragons' Den and has continued to grow its lender coverage since. For a full breakdown of the business model, see our how does Sprive make money explainer.

Who it may suit: homeowners who want a purpose-built tool that handles overpayments end to end, particularly those with supported lenders.

I've written a full Sprive mortgage app review with an honest verdict after years of use. For a step-by-step walkthrough of the setup, our how the Sprive app works guide covers each stage. If your main concern is whether the app is trustworthy, our is Sprive safe page covers FCA status, Open Banking security, and fund protection in plain English.

Chip: build an overpayment pot with FSCS-protected savings

Chip is not a mortgage app, but it is one of the stronger tools for accumulating the cash you'll then send to your lender as an overpayment. It works by analysing your spending and automatically setting aside small amounts into an FSCS-protected savings account. You set the pace, and Chip does the rest.

The key advantage over Sprive here is that your money earns interest while it sits in Chip, with eligible deposits held by ClearBank and protected up to £120,000 per eligible person per UK-authorised bank, building society or credit union by the FSCS (since 1 December 2025). You can then make a lump-sum overpayment to your mortgage whenever you're ready. This may suit people who prefer to build up a pot and overpay quarterly or annually rather than sending small amounts every month.

Chip also offers investment options if you'd rather grow your pot in funds instead of cash, though that introduces risk. For pure overpayment savings, the instant-access account is the practical choice.

Who it may suit: people who want to save automatically with FSCS protection, then overpay manually in larger chunks.

Plum: autosaving and round-ups for spare cash

Plum takes a similar approach to Chip: it connects to your bank, watches your spending, and sweeps small amounts into a savings pot. The difference is in the detail. Plum uses an automated calculation to work out how much you can safely save each week, and it offers round-ups on card transactions so your spare pennies accumulate automatically.

Plum doesn't send overpayments to your lender directly. You'd withdraw from Plum and transfer the money yourself. However, as a tool for painlessly building up an overpayment fund, it's effective. There's a free tier with basic autosaving, and paid plans (from £2.99/month) unlock extras like higher interest on savings and investment options. Plum is FCA-regulated and offers FSCS protection on its savings pockets provided by Investec Bank.

Who it may suit: people who like round-ups and want an automated approach to finding spare cash.

Emma: find the money before you overpay it

Emma is a budgeting app rather than a savings or mortgage tool, but it earns a spot on this list because it solves a different problem. Before you can overpay anything, you need to know where your money is actually going. Emma connects to all your bank accounts and cards, tracks your subscriptions, flags wasteful spending, and shows you a clear picture of your cashflow.

The practical use case: you run Emma for a month, spot that you're paying £40 for a gym you never visit and £12 for a streaming service you forgot about, cancel both, and redirect that £52 towards your mortgage. That's £624 a year in overpayments you didn't have to find.

Who it may suit: people who suspect they're leaking money but haven't pinpointed where.

Our Emma app review covers the full verdict. If you want to try it, our Emma app premium trial page has an extended free trial offer.

TopCashback: earn overpayment cash from spending you'd do anyway

TopCashback works differently from everything else on this list. There's no Open Banking connection and no autosaving. Instead, you earn cashback on online purchases from thousands of retailers by clicking through the TopCashback site or app before you buy. The cashback builds up in your account, and you withdraw it as real money.

The mortgage connection is simple: if you're earning £20 to £50 a month in cashback on things you were buying anyway (insurance renewals, broadband switches, online shopping), that's money you can redirect straight to your mortgage as an overpayment. Over a year, it adds up surprisingly fast.

Who it may suit: online shoppers who want a passive way to generate overpayment cash without changing habits.

Our TopCashback referral code page has the current sign-up bonus.

Your bank's own app: the free option everyone forgets

Before downloading any dedicated mortgage overpayment apps, check what your existing lender already offers. Several major UK banks and building societies now let you set up and manage overpayments directly through their mobile app.

Nationwide lets you manage overpayments and has a built-in overpayment calculator. Halifax offers overpayment tools through its app. HSBC, Lloyds, and NatWest all support online overpayment management too.

The trade-off

The advantage is zero setup friction: you're already a customer, you already have the app, and there's nothing extra to connect. The downside is that none of these apps help you find the money or automate the saving side. You still need the discipline to set up a standing order or make manual payments each month. For some people, that's perfectly fine. For others, the automation from a dedicated app like Sprive or Chip is what makes the difference.

If you don't have a current account that works for you, Monzo is worth exploring. Its "Pots" feature lets you ring-fence money for specific goals, and you can set up automatic rules to fill your overpayment pot. Our Monzo referral page has the current sign-up bonus.

The manual standing order: still a solid strategy

No apps, no connections, no Open Banking. Just a fixed standing order from your current account to your mortgage lender for an extra £50, £100, or whatever you can afford each month. It's predictable, it's free, and it works.

The drawback is that it doesn't adapt. If your spending spikes one month and you can't afford the overpayment, you either cancel the standing order or risk going short elsewhere. That's the core problem Sprive was designed to solve: flexible, spending-aware saving instead of a rigid fixed amount. Our Sprive vs manual overpaying comparison covers this trade-off in detail.

Saving and investing as an alternative

If your mortgage rate is relatively low, you might earn more by putting spare cash into a high-interest savings account or a Stocks and Shares ISA rather than overpaying directly. In June 2026, the Bank of England base rate stands at 3.75% (held 30 April 2026, next decision 18 June 2026). Average two-year fixed rates are around 5.64% and average SVRs around 7.13%, according to Moneyfacts as of early June 2026. For most borrowers currently on SVR or a higher fix, overpaying is likely to deliver a better effective return than cash savings.

We've written a dedicated post comparing the two approaches: overpay mortgage or invest.

Which mortgage overpayment app is right for you?

There's no single best mortgage overpayment app because it depends entirely on your habits and preferences. Here's a quick guide:

Want everything automated and mortgage-specific? Sprive may be worth trying first.
Prefer to build a savings pot first, then overpay? Chip or Plum may do the heavy lifting.
Need to find spare cash before anything else? Emma will show you where the money is going.
Want passive cashback you can redirect? TopCashback earns money on purchases you'd make anyway.
Just want a simple, free method? A standing order through your lender's own app costs nothing and works.

You can also combine them. Use Emma to find savings, Chip to accumulate the cash, and then either Sprive or your lender's app to make the actual overpayment. The best mortgage overpayment apps solve different parts of the same problem.

Whatever route you choose, make sure you understand your overpayment rules and limits before you start. Getting hit with an Early Repayment Charge because you exceeded your allowance would wipe out the benefit. Our Sprive overpayment rules guide covers what to check, and our mortgage overpayment UK explainer has the broader picture.

FAQs

Is there an app that pays off your mortgage for you?

Sprive is the closest thing to this in the UK. It automatically sets aside small amounts based on your spending and lets you send overpayments to your lender in one tap. However, no app can make payments without your authorisation. You always stay in control of how much is saved and when overpayments are sent. For the full breakdown, see our step-by-step guide to how Sprive works.

Are mortgage overpayment apps safe?

Apps like Sprive use Open Banking to connect to your bank, which means they can read your transactions but cannot access your login credentials or move money without your permission. Sprive is FCA-registered (FRN 919863, appointed representative of Connect IFA Ltd FRN 441505) and uses regulated payment partners. Money held in e-money wallets (like Sprive's) is safeguarded, not FSCS-protected, which is an important distinction. If you want the savings pot to be fully FSCS-protected while you build it up, an app like Chip may be a better fit for the accumulation stage. For more detail, read our is Sprive safe guide.

How much can you save by overpaying your mortgage?

It depends on your balance, rate, and how much extra you pay. As a rough example: on a £200,000 mortgage at 5% over 25 years, overpaying by just £100 a month could save you around £20,000 in interest and knock roughly four years off your term. Even £50 a month makes a meaningful difference over the full life of a mortgage.

Can I use more than one mortgage overpayment app at the same time?

Yes, and it often makes sense. For example, you might use Emma to track spending, Chip to accumulate savings in an FSCS-protected account, and Sprive to handle the actual overpayment and track your mortgage progress. They solve different problems and don't conflict with each other.

What if my lender isn't supported by Sprive?

According to Sprive's FAQ, the app currently supports Nationwide, First Direct, HSBC, Lloyds, Barclays, Santander, RBS, Virgin Money, Halifax, NatWest, Yorkshire Building Society, Coventry Building Society, Accord Mortgages, and TSB Bank. If your lender isn't on the list, you can still use the autosaving feature to build up your pot and then transfer the money to your lender manually. Alternatively, a savings app like Chip combined with a standing order achieves a similar result.

Should I overpay my mortgage or save the money instead?

If your mortgage rate is higher than the best savings rate you can get after tax, overpaying gives you a better effective return. If your savings rate genuinely beats your mortgage rate, holding the cash and overpaying later could leave you better off. In June 2026, with the average SVR at around 7.13% and average two-year fixes around 5.64% per Moneyfacts, overpaying is the stronger option for most borrowers. We've written a full comparison here: overpay mortgage or invest.

Do I need to tell my lender I'm using a mortgage overpayment app?

You don't need to tell them about the app itself, but it's worth checking with your lender how they process overpayments. Some automatically reduce your term, others reduce your monthly payment unless you specifically ask. You should also confirm your annual overpayment allowance so you don't accidentally trigger Early Repayment Charges.
