Most of the major research funders in the UK have included in their terms and conditions of award a requirement for researchers to acknowledge in any publication the support received from the funder in question.
The acknowledgement of funding should take the form of a sentence with the funding agency written out in full, followed by the grant number in square brackets, for example:
This work was supported by the Economic and Social Research Council [grant number xxxx].
Multiple grant numbers should be separated by a comma and space. Where the research was supported by more than one agency, the different agencies should be separated by a semi-colon, with "and" before the final funder. For example:
This work was supported by the Wellcome Trust [grant numbers xxxx, yyyy]; the Natural Environment Research Council [grant number zzzz]; and the Economic and Social Research Council [grant number aaaa].
