The short answer
Casual dating means different things to different people. For some it is a casual fling with no future plans, for others it is a casual relationship that carries on for months without the usual expectations. This guide explains what casual dating sites in the UK actually offer, how they differ and what to check before you hand over any money or personal details. Updated October 2026.
We are an independent comparison and consumer-guide site for adults aged 18 and over. We do not describe anything explicit, and we do not claim to have tested the platforms. Where a fact comes from the platform itself, we say so. Where it could not be confirmed without an account, we say that too.
What casual dating means in the UK
Casual dating is dating without the assumption that it will lead to a long-term commitment. People usually mean one of three things: meeting someone once or occasionally, seeing someone regularly with no exclusivity, or keeping things light while they are busy with work, study or life after a break-up.
None of these is better or worse than the others. What matters is that both people understand and agree on what is happening. Most disappointment in casual dating comes from a mismatch in expectations, not from the site that was used to meet.
Casual dating websites and casual dating apps
A casual dating website is a service where adults state up front that they are looking for something relaxed. That is the main difference from mainstream dating apps, where many members want a partner and some want something lighter. If you are wondering whether a mainstream app can do the job, our article on whether Tinder is good for casual dating looks at that question, and hookup apps versus dating apps explains the wider differences.
Casual fling or casual relationship: what is the difference?
The two phrases are often used as if they mean the same thing, but they set different expectations. The table below is a general guide, not a rule, and you should always check with the person you are talking to.
| Question | Casual fling | Casual relationship |
|---|---|---|
| How long does it usually last? | A short period, sometimes a single meeting | Weeks or months, with no fixed end |
| Is there regular contact? | Usually only to arrange meeting up | Often regular messages and plans |
| Is exclusivity expected? | Normally not discussed | Should be discussed openly |
| What needs agreeing early? | Expectations, consent, how to end contact politely | Boundaries, honesty about other people, what happens if feelings change |
| Typical risk | Misread signals or pressure | One person starting to want more |
If you want a deeper look at the second column, our guide to casual dating boundaries covers how to raise the subject without awkwardness. For the friendly-but-flexible version of casual dating, see casual dating versus friends with benefits.
Casual dating sites compared: the five platforms
We compare five platforms that are available to UK adults: BeNaughty, FriendsWithBenefits, NaughtyCharm, OneNightFriend (shown as ONF in our tables) and Shag. The figures and descriptions below are taken from the information held in our content system for each platform, so treat them as what the platform says about itself rather than as independent measurements. Member numbers in particular are claims we cannot verify, and they may refer to members worldwide rather than in the UK.
| Platform | Stated member base (according to the platform) | Stated age group | How it describes itself |
|---|---|---|---|
| BeNaughty | About 1,000,000 members | 20-45 | "For fun adventures" |
| FriendsWithBenefits | About 2,500,000 members | 20+ | "Casual dating for adults. No strings attached." |
| NaughtyCharm | About 370,000 members | 20+ | "Cut the small talk. Find your person." |
| OneNightFriend (ONF) | About 1,300,000 members | 20-45 | "Meet people for a night" |
| Shag | About 1,200,000 members | 25+ | "Casual encounters near you. Discreet, free to join, active UK members." |
A bigger stated member base does not guarantee that more people near you are active, and a smaller one is not necessarily worse. In practice, what matters is how many active members are in your area, which you can only judge once you have created a profile and looked around.
Reviews of each platform
We have written a separate review for each partner, covering how it works, what it says about pricing and how to leave it. Start with BeNaughty, FriendsWithBenefits, NaughtyCharm, OneNightFriend or Shag. The order in which the platforms appear in our ranking panel is shown separately from this text and is not repeated here.
How casual dating websites differ from one another
All five platforms are built around adults who want something relaxed, but they present themselves differently. The table below lists the points the platforms themselves highlight. Where we could not confirm a detail without an account, we have written "not confirmed".
| Feature | BeNaughty | FriendsWithBenefits | NaughtyCharm | ONF | Shag |
|---|---|---|---|---|---|
| Free to join | Not confirmed | Listed as free | Sign-up stated as free | Not confirmed | Stated as free to join |
| Mobile use highlighted | Yes | Not confirmed | Not confirmed | Yes | Not confirmed |
| Matchmaking highlighted | Yes | Not confirmed | Not confirmed | Yes | Not confirmed |
| Search by location | Not confirmed | Stated: find people near you | Not confirmed | Not confirmed | Stated: encounters near you |
| Discretion highlighted | Not confirmed | Not confirmed | Not confirmed | Incognito search mentioned | Stated as discreet |
| Other stated features | A variety of interaction features | Contact people like you | Not confirmed | Chat rooms; Premium package | Active UK members |
"Free to join" is not the same as "free to use". On many adult dating services, creating a profile costs nothing but sending messages, reading replies or using extra features may need a paid plan. We discuss this in the next section and in our guide to whether hookup sites are free.
Free or paid: what casual dating sites cost
We have not published prices for any platform because we could not confirm a current price from an official page without creating an account, and prices change. Rather than guess, here is what typically affects what you pay on this kind of service.
| Factor | Why it matters | What to check |
|---|---|---|
| Plan length | Longer plans often show a lower monthly figure but a bigger single payment | The total charged today, not only the monthly equivalent |
| Auto-renewal | Many UK online subscriptions renew automatically | Whether renewal is on by default and when it is charged |
| Credits or extras | Some features may be paid for separately | What is included in the plan and what is an add-on |
| Introductory offers | A low first price can rise at renewal | The price after the first period |
| Payment channel | Card, app store or other methods can be cancelled in different places | Where the subscription appears and how to stop it |
| Billing descriptor | The name on your bank statement may differ from the site name | Whether you are comfortable with how it appears |
If you do choose a paid plan, write down the date and the cancellation steps at the time. For platform-specific detail, see our articles on BeNaughty cost and cancellation and FriendsWithBenefits cost and cancellation. If a charge looks wrong, contact the platform first, then your card provider, and use Citizens Advice for free consumer guidance. Trading Standards can also be told about misleading practices.
If cost is your main concern, our page on free hookup sites explains what "free" usually covers.
Honesty and expectations in casual dating
The kindest thing you can do in casual dating is to be clear. That does not mean sharing everything about yourself. It means not letting someone believe something that is not true.
Say what you are looking for in your profile
A short, plain sentence works better than a vague one. "Looking for something relaxed, nothing serious" is clearer than "see where things go". Clarity filters out mismatches before anyone gets hurt.
Talk about boundaries before you meet
Boundaries are the limits each person sets: how often to meet, whether it is exclusive, what you share about your life and how you will tell each other if something changes. Agreeing them early is easier than renegotiating later.
Respect a no, and accept silence
Consent is ongoing and can be withdrawn at any time. If someone stops replying, that is an answer. Repeatedly messaging a person who has not responded is not acceptable and can break platform rules and, in some cases, the law.
- Be honest about your relationship status.
- Do not pressure anyone to share photos or personal details.
- End things politely if your wishes change.
- Remember that real people are behind every profile.
Safety, privacy and scams on casual dating websites
Adult dating services attract scammers because users are often discreet and may be reluctant to complain. Knowing the common patterns makes them easier to spot. Our longer article on whether hookup sites are safe goes into more detail.
| Warning sign | What it may mean | What to do |
|---|---|---|
| Very fast declarations of interest | A fake profile or a scripted approach | Slow down and ask specific questions |
| A request for money, gift cards or crypto | A romance scam | Stop contact and report the profile |
| Pressure to move to another app quickly | An attempt to avoid platform moderation | Stay on the platform until you are comfortable |
| Photos that look too polished or inconsistent | Stolen images | Try a reverse image search |
| Links to outside sites or payment pages | Phishing or paid-for chat services | Do not click; report it |
| Reluctance to talk on video or in person | The person may not be who they say | Consider a short video call before meeting |
Protect your privacy
- Use a separate email address for dating accounts.
- Avoid sharing your full name, workplace, home address or social media handles early on.
- Check what the platform says it does with your data in its privacy policy.
- Check how the charge appears on your bank statement if discretion matters to you.
Meeting for the first time
Meet in a public place, tell a friend where you are going and who with, arrange your own travel home and keep your phone charged. If anything feels wrong, leave. If you are sexually active with new partners, use protection and know that NHS sexual health services offer confidential advice and testing.
Where mainstream dating apps fit
Mainstream apps such as Tinder, Bumble and Hinge are not among the platforms we compare here. They generally offer a free basic version with paid upgrades, and their terms change over time, so check the current details in the app store. Their members want a range of things, so you will need to state your own expectations clearly. For a broader comparison, read our overview of hookup apps or the wider list of hookup sites.

How to choose a casual dating site
- Decide what you want. A casual fling, a casual relationship or a more specific arrangement such as friends with benefits, or a single meeting as discussed in our one night stand apps guide.
- Read the terms before paying. Look for renewal, cancellation and refund wording.
- Start with the free parts. If a platform is free to join, see how many active profiles you can find locally before you pay.
- Check discretion settings. Look at profile visibility and photo controls.
- Set a budget and a time limit. It is easier to stop if you decided in advance.
- Keep the first meeting simple. A public place and a short time.
Our approach and how we earn money
We may earn a commission if you follow a link on this site and join a platform, at no extra cost to you. This does not change our assessment. We do not use numeric scores in the text, and the order of the ranking panel is shown separately. All details here are based on information from the platforms themselves and general consumer advice, and may change. Always check the current terms on the platform before paying.
This guide is for adults aged 18 and over. If casual dating stops feeling enjoyable, it is fine to take a break.
