Fares are usually outrageously high. Can be handy sometimes tho but overall complete rip off. Price can jump to 20 pound in a matter of minutes for a 10 minute drive, like really??. Also if the uber takes long due to traffic (out of your control, not like you get to pick the route with least traffic,the driver does) then they charge you more money. Also it isn't very available across the UK, only in some areas making it inconvenient. My main concern overall is the price though.
