Jane Traies, who is based at the University of Surrey, is pioneering research on the lives of older lesbians in the UK. It is in its preliminary stages but you can read her dissertation and a blog charting progress http://womenlikethat.co.uk/

We have a (funded!) LGBT history project in Leicester at Leicester LGBT Centre. I’ve been part of it: http://www.leicesterlgbtcentre.org/news/165-history-project-listen
I also went to “Older Bisexual Lives – Current Initiatives & Future Directions” in April in Nottingham. This was part of an ESRC seminar series on Older Lesbian, Gay, Bisexual and Trans People called ‘Minding the Knowledge Gaps’. The project involves a series of six themed seminars followed by a final conference, aimed at exploring gaps in knowledge and research about Lesbian, Gay, Bisexual and Trans (LGBT) Ageing, and identifying ways to address those gaps.

The next seminar is on ‘Intergenerational Issues’ and will be in Oxford on 10th September.
