What is Monzo Billsback, and is it worth it? 2026 review

Monzo Billsback is a monthly prize draw that pays back eligible household bills, up to £150 per bill, for at least 1,000 winning customers each month. It's a benefit of Monzo's paid plans (Extra at £3/month, Perks at £7/month or Max), not guaranteed cashback: bills you pay from your personal Monzo account are entered automatically, and a random draw each month decides which ones get refunded in full, up to the £150 cap. Most subscribers never win; a small number win repeatedly.

I've been enrolled in Billsback since November 2025 and have had a chance to see how it works in practice.

If you don't have a Monzo account yet and want to open one first, you can open an account with a Monzo referral link to claim a mystery reward of £20, £50 or £100 when you make your first card payment.

What is Monzo Billsback?

Billsback launched in autumn 2025 as a perk of Monzo's paid current account plans. To take part, you need to be subscribed to Monzo Extra (£3/month), Monzo Perks (£7/month) or Monzo Max (see Extra vs Perks vs Max for what each tier includes), be a UK resident aged 18 or over, and pay an eligible bill from your personal Monzo account. Enrolment is automatic: if you're on a qualifying plan, you're already in the draw.

How Billsback works in practice

What counts as an eligible bill? Any bill over £1 paid to a merchant on Monzo's "agreed providers" list, settled via BACS Direct Debit or Mastercard card payments, from your personal account. BACS is the bank-to-bank system UK Direct Debits run on, so a bill you pay by manual bank transfer is a different thing and doesn't count. The list covers most major UK bill providers: the big energy suppliers, mobile networks, broadband providers, streaming services, council tax authorities, and more. I have Octopus Energy, Spotify, giffgaff, Netflix and Thames Water set up as eligible bills.

Each eligible bill is a separate entry. Pay five Direct Debits in a month and you have five chances to win, but only one can be paid back in any single draw (and only up to £150).

The maths: what is Billsback actually worth?

If you're going to pay £3–£7/month for a Monzo plan partly because of Billsback, the sensible question is: what's the expected value of the draw?

Monzo doesn't publish the total number of entrants, so precise odds are impossible. Working backwards from what is public:

• At least 1,000 bills are paid back per month.
• The average UK household Direct Debit for energy, broadband, mobile and a streaming service combined is roughly £150–£250.
• Monzo has more than 16 million personal and business customers, but doesn't break out how many pay for a plan. I've put the Extra, Perks and Max base at 500,000 to 1.5 million, which is my own estimate rather than a share of that headline: it counts business customers, who can't buy a personal plan.
• Each subscriber typically has multiple eligible bills per month. Let's assume three on average.

If we take a midpoint estimate of 1 million paid subscribers × 3 eligible bills = 3 million eligible bill entries per month. With 1,000 winning bills, that's roughly a 1-in-3,000 chance per bill, or about 1-in-1,000 chance per subscriber per month of winning something.

Expected value calculation (per subscriber, per month):

• 1-in-1,000 chance × average bill value of ~£100 (most eligible bills are smaller than the £150 cap) = ~10p expected value per month.

Even with generous assumptions (100,000 total subscribers instead of a million) the expected monthly return is still only £1–£2.

The subscription costs £3–£7/month, so on pure expected-value grounds Billsback alone does not pay for the Extra or Perks fee.

My Billsback experience so far

I've not won anything yet. I pay around 5 eligible bills per month, which vary in value from £10 to £170.

I have friends who've won Billsback rewards for their energy bills.

In my opinion, the main reason to pay for a Monzo plan is for the other benefits. Billsback is a free bonus on top.

Which bills qualify and which don't

The eligible-provider list is the single biggest source of confusion around Billsback. Some examples based on Monzo's current guidance (always check the latest list in-app before relying on it):

Usually eligible:

• Major UK energy suppliers (Octopus Energy, British Gas, E.ON Next, EDF, OVO, Scottish Power, Shell Energy, etc.)
• Mobile networks (EE, Vodafone, O2, Three, giffgaff, VOXI)
• Broadband and TV providers (BT, Sky, Virgin Media, Now, Plusnet, Hyperoptic)
• Streaming subscriptions (Netflix, Disney+, Spotify, Apple services)
• Water companies
• Council tax (via Direct Debit)
• Some insurance premiums

Usually ineligible:

• Anything paid from a Monzo Business account
• Payments settled by bank transfer instead of Direct Debit or Mastercard
• Bills under £1
• Payments to providers Monzo hasn't added to the agreed list (this includes some smaller challenger energy suppliers, niche subscriptions, and most one-off payments)
• Rent (unless paid by Direct Debit to a letting agent on the list, which is rare)

If you're unsure about a specific merchant, the Monzo app shows your eligible bills inside the Billsback section. Bills that don't qualify simply won't appear there.

Billsback vs guaranteed cashback alternatives

If the lottery element of Billsback doesn't appeal, there are UK bank accounts that pay guaranteed cashback on bills.

Santander Edge (£3/month): Pays 1% cashback on household bills (energy, council tax, water, broadband, mobile, TV) paid by Direct Debit, capped at £10/month, and asks for £500 paid in each month plus two active Direct Debits. It pays nothing on debit card spending: the supermarket, travel and fuel cashback belongs to Edge Explorer at £17/month, not to Edge. For anyone with £1,000/month of eligible bill spend, Edge is a guaranteed £10/month back: net £7/month.

Chase UK (free): Pays 2% cashback on everyday spending (groceries, transport, fuel and eating out, not bills), capped at £20/month, subject to monthly qualifying criteria. The conditions and exclusions are set out in full in Monzo vs Chase.

Honest comparison: if guaranteed cashback on bills is what you want, Santander Edge is almost certainly the better product than paying for a Monzo plan purely for Billsback. Monzo wins on app experience, budgeting tools and speed, but on the narrow question of "cashback on bills", Santander's maths is hard to beat.

That said, Billsback has an asymmetric upside Santander Edge doesn't. A winning Billsback month of £150 for a single £150 Direct Debit is equivalent to 100% cashback on that bill. Santander's 1% cap means you can never win big.

Is Monzo Billsback worth it?

If you're already paying for Monzo Extra, Perks or Max for other reasons, Billsback is a genuine free bonus. Take it, enjoy the occasional win, and don't count on it for your household budget.

If you're considering a Monzo plan solely for Billsback, the expected-value maths doesn't support it. You'd be paying £36–£84/year for roughly £10–£20 of expected return, so you'd be better off on a free account and running your bills through Santander Edge or Chase for guaranteed cashback.

Put plainly: Billsback is a lottery ticket your subscription fee buys. If the other benefits justify the subscription, the ticket is free. If they don't, you're paying retail for a low-odds draw.

Monzo Billsback FAQs

How is the winner chosen?

Monzo sends an in-app notification and credits the bill amount directly to your account. You can also check the Billsback section of the app for a history of eligible bills and any payouts.

Can I opt out of Billsback?

Billsback is a benefit of the paid plans rather than something you'd typically want to opt out of. If you no longer want to take part, the route out is to downgrade to the free Monzo account.

Does Billsback count as taxable income?

Billsback payouts are generally considered prizes rather than cashback or interest, which for most personal customers means they're not taxable. This is not tax advice. If you're in any doubt about your specific situation, check with a qualified adviser or HMRC.

Can I use Billsback with a joint account?

Yes, provided the joint account is on a Monzo Extra, Perks or Max plan. Both account holders can benefit from eligible bills paid through the joint account.

Is Billsback available on Monzo Business?

No. Billsback is only available for bills paid from personal Monzo accounts. Business account payments are not eligible.

The expected-value section is my own arithmetic on stated assumptions, not a Monzo figure. Monzo publishes the cap per bill, but no public page carries the monthly winner count or the number of entrants, which is why the odds here are labelled as an estimate in the copy rather than quoted.

Opening via a Monzo referral link adds a one-off mystery reward of £20, £50 or £100 when you make your first card payment: a guaranteed bonus that compares favourably to the expected value of several years of Billsback entries combined.
