Don't know whether anyone would find the below database of any use, free and from the BHA website
"You can find all published handicap ratings for British-trained horses in the table below, updated each week on Tuesday morning.
The ratings are listed alphabetically but you can search by trainer name, horse name or by rating; you can also export the full list of ratings or weekly rating changes to an Excel spreadsheet free of charge."

NigelK has kindly already shared a spreadsheet to import all this into Excel already
