The job offers in the NHS are usually a range rather than a specific value. This allows the department flexibility to present a job offer dependent on candidate experience and aptitude for the role.
The basic rule is that the greater the number of hours worked per week in the job, particularly anti-social hours (outside of 8am-5pm Monday to Friday), the greater the pay.
Our friends at Road to UK have worked hard to produce a guide to doctor pay in the UK. The system seems complicated at first glance, but if you read this guide, then you should feel clear on the pay system and an estimate of the compensation for different jobs.
Find the information here. You will have to create a free account with Road to UK to see this article, but you will find so much helpful information on their website about moving to the UK to start an NHS job, we recommend joining their community anyway.
