Hi there
Tony helped me with the underlying function and I got all that working - now the 'powers that be' have decided that they only want to round UP to the nearest quarter hour, not up and down - any more ideas please - thanks - Julia:

You got there with the ...
On an A1 time of 02:51
The MOD function gives 0.114583333
All you have to do is format you result (0.114583333) as a time (mm:ss).
It shows as 02:45.
As for 0.01041666 being 15 minutes. This is 1 (day) divided by 24 (hours), divided by 4 (quarters).
0.25 (to Excel) would be 6 hours (quarter of 1 day).
Hope this helps.
Tony
