The average UK salary is £26,462 but as you might imagine, there are plenty of jobs which pay considerably more and a lot less than that. Think you know which roles bring in the big bucks? You might be surprised...
Stories of plumbers earning six-figure salaries have been rife in recent years - but according to official figures, the average UK salary for plumbers is a more modest but healthy £27,866. However, like many sectors, much depends on the region you're working in and whether you're self employed. In London and the South East, plumbers have been known to charge up to £90 an hour. So, while £100,000 may be far-fetched in many parts of the country, self-employed city plumbers could easily earn £50,000 - making it one of the better-paid trades.
Driving a bus is arguably more challenging than driving a train (given the added pressures of the road, other traffic, and having passengers to deal with), so you might be surprised to learn that bus drivers earn half of what train drivers take home. The average UK salary for bus and coach drivers is just £22,701 - compared to £44,617 for tram and train drivers.
Secretaries may possess similar skills, but where they work can make a huge difference to their pay packet. While medical and legal secretarial positions pay more than the average admin job (the average UK salary is £20,474 and £18,866 respectively), it's a lot less than those working as personal assistants, who earn £24,067. Prove yourself invaluable to the big boss at a multinational organisation and your PA salary could easily rise to £50,000 a year.
Get a book published and you can relax and think about retirement, right? Sadly, that's fiction. The average published author in the UK earns just £5,000 a year from writing - which is even more pitiful when you realise that many authors can take years to finish a book. Like acting, writing is a 'winner takes all' game where only the top few make the big money. J. K. Rowling may be worth a phenomenal £560 million, but she is one of the rare few.
You might think household names on TV earn a fortune, but pay within the entertainment industry can vary hugely. Take the professional dancers on Strictly Come Dancing. Billed as the "real" stars of the BBC show, the likes of Brendan Cole and Ola Jordan (who work up to 14 hours a day training celebrities and choreographing dances) are paid £30,500 per series.
Not bad for three months work you might think - until you compare their salary to that of the judges, who earn £110,000 per series and veteran Bruce Forstyh, who gets £550,000. But those salaries are dwarfed by those of the judges on ITV rival the X Factor. Gary Barlow recently signed a £2 million deal, while Louis Walsh is believed to get £850,000 per series.
David Cameron earns just £142,500 a year for running the country - a fraction of what chief executives of multi-national companies take home in salary and bonuses. Despite the PMs relatively small salary, not every one in official posts takes home a modest pay check.
According to a recent report by the Taxpayers' Alliance, as many as 2,525 council staff earn more than £100,000 while 42 local authority employees are on more than £250,000. Nearly 8,000 NHS staff were paid a six-figure salary last year - with the highest-paid executive taking home £340,000 - almost 16 times the pay of the average ward nurse, on £21,000.
Still, it's not all bad news for Mr Cameron. Gordon Brown earned £1.37m from extra work beyond his MP's duties last year, such as speeches and writing jobs, and Tony Blair's various business interests since leaving office has led some to put his net worth at about £20 million.
