Plenty of Fish was one of the first free dating sites when it launched in 2003, and today around 800,000 people in the UK peruse the page everyday. The site offers a matchmaker feature based on a personality test, as well as forums, games like fill in the blank and in depth profiles. Along with the standard age and job, you’ll find information like the length of their longest relationship, and whether they have siblings. Bear in mind, the number of men on Plenty of Fish outnumber women by 20 per cent.

There’s also the option to pay for additional features, which starts at £9.99 per month. With this, you’ll be able to see extended profiles, view read receipts on messages, scrap adverts, see who has viewed your profile, send virtual gifts and be more visible in searches by other members. You can use the site online or on a phone app.
