Casino bonuses all look generous at first glance. A headline figure of 100% up to £200 sounds impressive until you read the terms and discover a 40x wagering requirement attached to it. Smart comparison means looking past the banner and calculating what a bonus is genuinely worth in pounds and pence. The figures below give you a workable method.

Under UK Gambling Commission rules, licensed operators must display key terms clearly, including wagering contributions and time limits. That transparency makes side-by-side comparison far easier than it once was. What follows is a practical framework any player can apply before claiming an offer.
Read the Wagering Requirement Before Anything Else
Wagering, or playthrough, is the single most important number on any bonus page. It tells you how many times you must stake the bonus (and sometimes your deposit) before withdrawing. A £100 bonus at 35x requires £3,500 of qualifying stakes. The same bonus at 20x requires just £2,000.
That difference of £1,500 is the real comparison point, not the headline amount. Industry averages for UK-licensed sites sit around 30x to 40x, so anything at 25x or below is genuinely competitive.
Check whether the requirement applies to the bonus alone or to deposit plus bonus. The latter doubles the effective figure and is far less favourable.
Also note the maximum bet permitted while wagering, typically £5 per spin or stake. Exceed it and the bonus and any winnings can be voided.
Weigh the Value of Free Spins and Cash Bonuses
Free spins are often valued at 10p each, so 100 spins carries roughly £10 of play value. Many sites restrict spin winnings to a capped amount, commonly £50 to £100, and apply separate wagering to anything you win. A cash match bonus, by contrast, is usually more flexible.
Compare the two properly by asking three questions. What is the spin value? What cap applies to winnings? How long do you have to use them? A 100% match up to £100 at 30x is often worth more than 200 spins at 10p with a 35x requirement on winnings.
Look at game contribution rates too. Slots typically contribute 100% toward wagering, while table games often contribute 10% or less. A bonus that looks ideal on paper may be painfully slow to clear if your preferred games are restricted.
Check Eligibility, Limits and Expiry Dates
Every bonus has an expiry, and 30 days is common for matched deposits while free spins frequently expire within 7 days. A £200 bonus you cannot realistically clear in the window is worth less than a £50 bonus with generous terms.
Minimum deposit thresholds matter as well. A £10 minimum keeps the barrier low, but check whether the bonus only unlocks at £20 or more. Payment method restrictions also apply; deposits via certain e-wallets are sometimes excluded from bonus eligibility.
The table below summarises what to prioritise when comparing two offers.
| Factor | Strong Offer | Weak Offer |
|---|---|---|
| Wagering requirement | 25x or lower | 40x or higher |
| Maximum bet while wagering | £5 or above | £2 or below |
| Bonus expiry | 30 days | 7 days |
| Slot contribution | 100% | 50% or less |
Finally, confirm the bonus is from a UK-licensed operator and that withdrawal terms are stated plainly. A bonus worth £1,000 on paper but tied to impossible conditions is worth nothing in practice. Compare the maths, not the marketing.
