How to Open a Smarkets Account: A Step-by-Step Guide for Matched Betting (2026)
To open a Smarkets account, sign up at smarkets.com with your email, password and date of birth, add the current 0%-commission promo code, then make a minimum £10 deposit by debit card. Your identity is usually verified automatically within a couple of minutes, so the whole process takes about ten.
You need an exchange account like Smarkets to lay bets, and laying is the half of matched betting that cancels out the bookmaker side and locks in a fixed return. Once you know what matched betting is and how lay betting works, the exchange is the one setup step left before your first real bet. Here is what each part looks like, including the bit that catches most beginners out.
Smarkets' welcome-offer terms (the COMMFREE code, the 0%-for-60-days period, the £10 minimum and the debit-card rule) change from time to time. The figures here were checked against Smarkets' own pages on 30 June 2026. Always confirm the live terms before you sign up. Matched betting is for over-18s.
Summary
- A betting exchange like Smarkets is where you place the lay bet, the half of matched betting a bookmaker cannot give you.
- Signing up takes about five minutes: email, password and date of birth, then your name, currency and address.
- Enter the promo code (COMMFREE at the time of writing) on the first sign-up page for 0% commission for 60 days. It cannot be added later.
- Your identity is checked after your first deposit, usually by an automatic electronic check that takes minutes and leaves no mark on your credit file.
- The minimum first deposit is £10, and to keep the 0% offer you must pay by debit card or instant bank transfer, not Skrill, Neteller, PayPal or a prepaid card.
- Once it clears you place your first lay on the exchange, sized with a calculator so it cancels the bookmaker bet. After the intro period, Smarkets' standard commission is 2%.
Why you need an exchange account for matched betting
Matched betting works by covering both sides of the same event. You place a normal back bet at a bookmaker, then place a lay bet against the same outcome at an exchange. When the lay is sized correctly with a calculator, one side covers the other and the result roughly cancels out. Bookmakers only ever take back bets, so the lay side has to happen somewhere else.
That somewhere is a betting exchange, and in the UK that means Smarkets or Betfair. An exchange lets ordinary customers take the other side of a bet, the role a bookmaker normally plays. Without one you can collect a free bet but cannot neutralise it, which is why opening an exchange account is the first practical step every new matched bettor takes. If laying is still fuzzy, our guide to how lay betting works covers it before you risk a penny.
Most beginners start with Smarkets. The commission is low, the lay screen is clean, and new customers get an introductory 0%-commission period that keeps early costs low while you learn the clicks. It is not the only choice, and many matched bettors end up with both exchanges, but it is the simplest place to begin.
Step 1: Create your account
Go to smarkets.com and start the sign-up. The first page asks for three things: your email address, which doubles as your username, a password, and your date of birth. This is also where the promo code goes, so if you want the welcome offer, type the current code (COMMFREE at the time of writing) into the promo field on this first page. You cannot add it afterwards, and forgetting it is the single most common sign-up mistake.
The second page collects your first name, last name, account currency and full address. Submit that and the account is created. Smarkets then sends a welcome email. Click the link inside it to verify your email address and you are in.
One thing not to worry about: Smarkets does not ask for a phone number at sign-up, so the details above are all you need. Smarkets sets out the same flow in its own help-centre guide to opening an account.
Step 2: Verify your identity
Before you can place a bet, a UK exchange has to confirm who you are. This is not Smarkets being awkward. It is a Gambling Commission rule. Under licence condition 17.1.1, every licensed operator must verify a customer's name, address and date of birth before that customer is allowed to gamble. Every exchange and bookmaker you ever use runs the same identity check.
For most UK customers it is invisible. Smarkets runs an automatic electronic check, comparing your details against official databases. It runs the moment you make your first deposit, the next step, and usually clears within a couple of minutes. That check is a soft search: Smarkets states it leaves no trace on your credit file and does not affect your credit rating, so opening an account will not show up when you apply for a mortgage or a loan.
If the automatic check cannot confirm you, Smarkets emails you for documents. You send one proof of identity (a passport, photo driving licence or national ID card) and one proof of address (a bank statement or utility bill from the last three months). They aim to review documents within 24 hours. One catch worth knowing: if your age is not confirmed within 72 hours of your first deposit, the account is paused until it is, so deal with any request promptly.
When I opened my first Smarkets account in 2022, this was the step that threw me. I had assumed I would be betting within minutes, but my electronic check did not pass first time, so I photographed my passport and a bank statement and waited a few hours for the review. It felt like something had gone wrong. It hadn't: a document request is routine, not a red flag, and once it cleared that afternoon everything worked as expected.
Step 3: Make your first deposit
With your details in, fund the account. In Smarkets, open your account menu and choose Deposit, pick a method and enter an amount. The minimum first deposit is £10, paid in a single amount, and that same £10 is what activates the welcome offer.
Here is the gotcha that costs beginners the 0% period: the qualifying deposit must be made by debit card or instant bank transfer. Deposits by Skrill, Neteller, PayPal or any virtual or prepaid card, including virtual Monzo cards, do not count toward the offer. Use an ordinary Visa, Mastercard or Maestro debit card and you are fine.
When I funded my own account I nearly paid in from a digital wallet out of habit. A quick read of the offer terms stopped me, and I used my debit card instead so the 0% period applied. Only deposit what you plan to use as working capital, and if betting ever stops feeling like a careful routine, free and confidential help is at GambleAware.
Step 4: Place your first lay bet
Now the exchange earns its place. Find your event and market on Smarkets and you will see two prices for each selection: a blue back price and a pink lay price. Backing is betting that something will happen. Laying, in the pink column, is betting that it will not.
To lay, click the pink price for your selection and enter your lay stake. You do not guess this number. Drop your back stake, back odds, lay odds and your commission rate into the standard matched betting calculator, and it returns the exact lay stake to type in. During your first 60 days on the COMMFREE offer that rate is 0%. After it, the standard 2% applies.
Say you backed a team at 2.0 for £10 and Smarkets is laying at 2.04. At the standard 2% rate the calculator returns a £9.90 lay stake and shows about £10.30 of liability. That is the most you could lose on the bet if the team wins.
That liability surprises people, because it looks far bigger than the stake. It is covered: when the lay loses, your back bet at the bookmaker wins by almost the same amount. With the stake sized correctly you finish only a few pence apart, not £10 down. The exchange just holds the worst case in your wallet, which is why you fund the account first. Read the back and lay screens twice before you confirm, and laying soon stops feeling strange.
Smarkets vs Betfair: which exchange should a beginner open first?
Smarkets and Betfair are the two UK exchanges, and the honest answer is that most matched bettors eventually use both. For a first account, though, Smarkets is the usual pick.
| Exchange | Standard commission | Liquidity | Best for |
|---|---|---|---|
| Smarkets | 2% | Good on major markets | A simple, low-cost start |
| Betfair | 5% | Deepest, especially on racing | Markets Smarkets does not list |
Commission is the clearest difference. Smarkets charges a flat 2% on your net winnings in a market, against Betfair's 5%, and that gap compounds across a year of offers. Betfair's strength is liquidity: more money sits in its markets, especially on horse racing, so you can match larger lays without moving the odds. Most people open Smarkets first for the lower cost, then add Betfair for the markets it is missing.
How this fits into your first matched bet
A funded exchange account is the platform for everything else. Your first qualifying bet comes next: find a close back-and-lay match with our standard oddsmatcher, grab a welcome offer from this week's sign-up offers, and place the two bets the way you just practised the lay. Our walkthrough of placing your first matched bet then runs the whole sequence, from picking the offer to turning the free bet into cash.
Frequently asked questions
Do I have to verify my ID to open a Smarkets account?
Yes, although for most people it happens automatically. UK-licensed exchanges must confirm your identity before you can bet, under Gambling Commission rules. Smarkets runs an electronic check after your first deposit and only asks for documents if that check cannot confirm you.
How much does Smarkets charge in commission?
New customers who enter the COMMFREE code pay 0% commission for 60 days. After that, Smarkets' standard rate is 2%, charged on your net winnings in each market rather than on every bet, and there is no commission on a market where you finish down. Check the live figures on Smarkets' own pages before you rely on them.
Will opening a Smarkets account affect my credit score?
No. The standard electronic identity check is a soft check, and Smarkets says it leaves no footprint on your credit file and does not affect your credit rating. Documents are only requested if the automatic check fails, and uploading them does not change that.
Can I do matched betting with just a Smarkets account?
No. The exchange is only the lay side. You also need bookmaker accounts, because that is where the back bets and the free bets come from. A Smarkets account on its own is half the setup.
Is Smarkets or Betfair better for matched betting?
For a first exchange, Smarkets is usually the better start: lower commission and a simpler lay screen. Betfair is worth opening alongside it for its deeper liquidity, especially on horse racing. Most matched bettors end up using both, reaching for whichever one lists the market they need.
How long does Smarkets verification take?
The automatic electronic check usually clears within minutes of your first deposit. If documents are needed, Smarkets aims to review them within 24 hours. You can fill in your details and deposit straight away, but you cannot place a bet until verification clears, so it pays to sort any document request quickly.
The practical takeaway
Opening the exchange is the one piece of admin between reading about matched betting and actually doing it. Sign up, drop in the promo code, let the electronic check clear, deposit £10 by debit card, and you have the lay side of every matched bet you will ever place. It is a ten-minute job you only do once.
From here the money side is straightforward, and the profits are tax-free in the UK. When you are ready, the free tutorial walks you through your first couple of offers with the calculator pre-filled and the lay ready to copy into Smarkets, and most members finish with around £40 in their account.
