It is not permitted to take photographs inside Westminster Abbey, but there are plenty of heraldic items to photograph in the Cloisters and the Chapter House there, where cameras are allowed.
One really fine and moving example of such is this memorial to John Kemp, Baronet, in the cloister area.
The text reads:
This is a close-up of the arms at the base of the monument:
Burke’s General Armory gives us the following:
Kemp (Gissing, co. Norfolk, bart.). Gules three garbs and a border engrailed or. Crest - On a garb or, a pelican vulning herself proper. Motto - Lucem spero [I hope for light].
Wikipedia in its entry "Kemp Baronets" notes that Sir John Kemp was the 6th Baronet. After his death, the baronetcy devolved upon his uncle, Sir Benjamin Kemp.
All in all, a very touching monument to a man of promise who died so young, and a nice depiction of heraldry for those of us interested in such things.
