Create your own layout. Don't use a pre-printed form from the internet.
There is no need for expensive folders for your application documents as is common practice in Germany. Some hospitals even consider faxed applications. However, using a clear layout and clean paper will increase your chances.

British CVs do not need a passport picture, so don't use a photograph unless explicitly required (e.g. in some application forms).
British CVs also have a short paragraph about your "career aims". This should consist of a few lines explaining why you are applying for this particular job. German applicants are used to writing this information in their covering letter, however, in many cases this letter will not even be forwarded to the consultants on the interview panel.

Try to make your qualifications comparable to British qualifications. If necessary, explain marks and scores you have achieved in exams. Give the British equivalent to the exam you passed (eg. Abitur = A-Level).

At the end of your CV there should be a section of "Referees". These are physicians or other respected persons that are willing to give information about you and your previous performance at work. It is not common to enclose written letters of reference "to whom it may concern" with your application. Instead, the referees stated on your CV will be contacted by phone, fax or letter once your appointment is considered. Therefore you should only list referees that are able to speak English.

Sometimes, not only is a CV is required but also an application form that will be sent to you from the medical staffing department. Try to get the document by email or on disk and fill it in on your computer. It may not be enough to fill the sections of this form with "see CV". Unfortunately, these forms are now common and take a considerable amount of time to fill in.
