Here's some useful advice from recruitment agency Euro London:

• Recruiters want a clear and concise document, no longer than two pages. Check your spelling!
• Split your CV into four sections: personal details, education and qualifications, employment history, interests and achievements.
• Include all the key information - your name, address, phone number(s) and e-mail address. Don’t worry about things like date of birth or religion.
• List all educational establishments you have attended, with dates of attendance, exams taken and grades achieved. Your professional qualifications should also be listed here.
• Employment history: the experience gained in your present post will usually be the most relevant to the job for which you are applying, so this is what you should always start with and devote the most space to.
• Try to outline particular achievements or results such as saving the company money or exceeding targets. Be concise, maybe use bullet points. Keep it simple and clear.
• Recruiters like to see precise dates i.e. March 1996 – February 1998, not 1996 – 1998. If you have a gap in your employment, account for the time and be honest about it.
• The skills section is where you can detail all language skills and their level of fluency - but make sure you make these language skills relevant to the job you're aplpying for.
• Also list technical skills, specifying all software packages, programming skills, hardware skills and knowledge of operating systems here.
• Try to get your personality accross. The fact that you play a team sport, for instance, can  display motivation, commitment, dedication and team work.
• Provide the names of two referees, either your last two employers or an academic referee. Their details can be provided further down the line should they be required.
