This is a sub-article in the Matched Betting Master Class pillar. The pillar covers strategy and breadth; this article is the live execution walkthrough.
Before You Start — Setup
You need three things ready:
- A bookmaker account with a "Bet £10, get £30 in free bets" offer (or similar). Sign up; deposit £20.
- A Betfair Exchange account, verified, funded with £100. Opening guide.
- Our matched betting calculator open in another tab.
The conceptual primer is in Matched betting explained. The Exchange mechanic is in lay betting explained.
The Walkthrough — 12 Steps
Read the offer's terms carefully. Note: minimum stake (£10), minimum odds (e.g., 2.0+), single bet only, free bet expiry (e.g., 7 days), free bet excluded markets if any. Screenshot the terms in case of dispute.
You want a market with closely-matched bookmaker and Exchange prices. Premier League Match Odds, big tennis matches, big horse races. Today's pick: Tottenham to win at 2.50 at the bookmaker, lay price on Betfair at 2.55.
Inputs: back stake £10, back odds 2.50, lay odds 2.55, commission 5%, mode "Qualifying Bet (Stake Returned)". Calculator output: Lay stake £9.95 (approx), liability £15.42, max loss ~£0.30 either way.
At the bookmaker: select Tottenham at 2.50, enter £10 stake, click bet. Confirm. Screenshot the placed bet.
Switch to Betfair. Find the same match Match Odds. Click "Lay" on Tottenham at 2.55. Enter the lay stake from the calculator (£9.95). Confirm. Screenshot.
Bookmaker bets section shows the £10 active bet. Betfair bets section shows the £9.95 lay matched. Screenshot both. The trade is live.
Don't watch. Don't add more bets. The trade is locked. Whatever Tottenham does, you'll be approximately scratch on the qualifying bet (£0.30 max loss). Result: free bet credit lands typically within 2 hours of match settlement.
Bookmaker emails confirmation. Account shows £30 free bet balance. Read the free bet terms again — minimum odds (typically 1.5+), expiry, excluded markets.
Higher odds extract more value from the free bet. Aim for 5.0-7.0. Today's pick: Manchester City to beat Brighton 3+ goals at 5.50 at the bookie. Lay price on Betfair: 5.60.
Inputs: back stake £30, back odds 5.50, lay odds 5.60, commission 5%, mode "Free Bet (Stake NOT Returned)". Calculator output: Lay stake £25.10 (approx), liability £115.46, profit £23 either way.
Select Man City over 3 goals. Enter £30 stake using the "Use free bet" toggle. Confirm. Screenshot.
Click "Lay" on Manchester City over 3 goals at 5.60. Enter the calculator lay stake (£25.10). Confirm. Screenshot. Match settles. Profit: ~£23 either way.
The Maths Recap
Qualifying bet: ~£0.30 loss. (Treat as the cost of triggering the £30 free bet.)
Free bet extraction: +£23 either way (already net of 5% commission).
Total profit: ~£22.70.
Time invested: 30-60 minutes for first bet (slower because of learning).
Common Mistakes to Avoid
- Wrong selection at one of the two venues. Always verify Manchester City Match Odds (bookie) = Manchester City Match Odds (Betfair). Watch BTTS, Over/Under, Both Teams Score — these are different markets.
- Wrong calculator mode. "Stake Returned" vs "Stake NOT Returned" is the most common error. Free bets typically don't return the stake; double-check the offer terms.
- Missing minimum odds requirement. "Minimum odds 2.0" excludes 1.99. Always read the small print.
- Placing both bets at the same prices but big slip between bookie placement and Exchange placement. Place the lay first when possible, or use software for near-simultaneous order entry.
- Insufficient Betfair balance for liability. A £30 free bet at 5.6 lay odds requires £115+ Betfair balance available. Check before clicking.
What to Do After Your First Bet
- Withdraw your initial bookmaker deposit after the bookie's withdrawal restrictions clear (typically after the qualifying bet settles).
- Move to the next bookmaker offer. 30+ UK bookies have signup offers worth £15-£75 net each. Three months of focused work can clear £600-£1,200.
- Read about reload offers. Best matched betting offers 2026.
- Consider a tracking subscription. OddsMonkey or Profit Accumulator (£15-£30/month) automate offer-finding. Pays for itself in single offers.

Master Class Pillar Open Betfair Account →Frequently Asked Questions
How long does the first matched bet take?
30-60 minutes for absolute beginners. By bet #5, you'll be at 15-20 minutes per offer. Pros knock them out in 5-10 minutes.
What if my qualifying bet wins?
Doesn't matter. The lay bet on Betfair cancelled out the result. Either way you're approximately scratch (~£0.30 loss).
What if Betfair price moves while I'm placing?
If it moves only 1-2 ticks, the trade still works. If it moves 5+ ticks, recalculate the lay stake. Software like Bet Angel reduces this risk by simultaneous placement.
Will the bookmaker close my account?
Maybe — eventually. Most matched bettors get gubbed at one or more bookies within 6-18 months. Avoid gubbing covers mitigation.
Is this really risk-free?
The maths is. Execution mistakes (wrong stake, wrong selection) introduce real risk. Always use the calculator and verify every input.
Matched betting is risk-free only when executed correctly. Every step matters. Always use the calculator. Always verify the bookmaker selection matches the Exchange selection. BeGambleAware.org if betting is causing distress.
