I couldn't recommend TopCashback enough. Since joining 8 years ago in 2014 I have earned £1078 in cash back which is incredible as it's essentially free money for clicking some links before making a purchase. I highly recommend signing up to the Plus membership for access to all of the exclusive benefits in exchange for £5 of your annual cashback earnings. The most important one being a higher rate of cashback which I believe is why my figure is so high. I would also download the browser extension too to get reminders to check and activate cashback. The mobile app is useful too if shopping online. You'll get a nice start with the referral reward and you can see your cashback build up overtime.
