Parship has a scientific approach to helping you find love. Relying on 40 years of findings on how to build a successful relationship, the site categorises users into 36 personality traits, and uses a matching algorithm of 136 rules. The compatibility questionnaire is extensive, and covers everything from what you look for in a partner to whether you sleep with the window open.

There is a fairly even male/female split in the users, and 52 per cent of them are graduates. The site welcomes 23,000 new members every week, and almost four in 10 find their partner through Parship. However, whilst it is free to sign up, take the comprehensive personality test, view your matches and send them ‘smiles’, you have to pay to be able to message your matches. Membership costs from £14.90 per month for 12 months, but you can trial the site for six months (£19.90 per month) or three months (£29.90 per month), too.
