Funding for research training and for undertaking research studies is available from various sources, both local and national. It is very competitive so do not be disheartened if you are not successful with an initial application. Often you can use reviewers' comments and rethink your ideas to develop and strengthen your proposal before submitting it to another funding body.
There may be a large charity associated with your clinical area which provides funding – look on their website and make contact with them. The Association of Medical Research Charities lists charities and what they fund.
The deadlines for applications are often tight and do not provide sufficient time for the preparation required to prepare a proposal from scratch. Most funders retain information about their grants, eligibility criteria and application process on their websites between funding calls so that you can see what is likely to be forthcoming. It is therefore wise to start writing your proposal and preparing your application at an early stage so that you are ready to respond to an opportunity when it is advertised.
The RCN publish a fortnightly Research Bulletin which provides information about current research funding available. The RCN also provies information on sources of research funding you may wish to consider.
