British equivalent of our Computaform

Hi Clansmen,

I have been looking for a form book in the U.K. which must be close to our Computaform. What is most important, it must show the "H/Av" H average.
In other words how much faster/slower the performance is when compared to a 'D-Division Handicap" average for that particular track.
So far I have been unsuccessful.

Please Help.

Racing Post, despite being a great form guide does not give this info.
