Unknown dragoon

Hi all

I am currently studying a journal written by a trooper who joined the 5th Dragoon Guards in 1807, serving in Spain 1809 onwards. He transferred to 10th Hussars late 1814 and then joined 11th Hussars 1820 and served in India including Bhurtpore. Can anyone save me an expensive trip to the regimental records in Kew please?
