If you already receive funding for your main degree from your local education authority, you'll be able to apply for funding for your intercalated year in the same way (but check with your LEA just to be sure!). Bear in mind that you may have to pay fees for the intercalated year, subject to means testing.
Bursaries and funds
There are various bursaries available to intercalating students, though we can't guarantee that every student will be able to find funding in this way. Some of these depend on the research topic that you choose.
A comprehensive and up-to-date list of charities that offer research funding is maintained by the National Institute for Health Research:
You should also check with your host department, as they may be aware of some specific research funding.
How intercalating affects your NHS bursary
Students whose main degree is MB BS are normally eligible to apply for NHS funding in the fifth year of their course. If you intercalate, the total length of your study becomes six years. This means that you will be entitled to apply for NHS funding in your fifth and sixth years of study (that's the equivalent of years 4 and 5 of your MB BS).
