The median salary in the UK is £20,801.
(The average salary is £26,020, and for full-time employees, that figure rises to £31,323. The top 1% of salaried earners, earn over £118,027, and people who earn £150,000 – the amount that triggers 50% income tax – are in the top 0.6%. Interestingly, in 1654, Oliver Cromwell was paid a salary of £70,000 a year. Kind of puts things into perspective really.)
