If you're looking for doctoral dissertations and theses, you can access them via our institutional repository ARRO and if you cannot find what you are looking for there then try using the British Library Ethos service.
We keep older physical copies of previous student's PhD and MPhil theses (1981-2019) for research purposes but we don't keep the dissertations of past undergraduate and masters students at the library. However, your department may keep some example dissertations from previous years so I would advise you to contact them.
