I have two children at Holy Ghost. When we moved to Clapham we didn't give any thought to distance from schools and were also told you literally need to live next door to the school to get in but that is not really true. It is a one form entry so places are very limited but provided that you meet the practicing Catholic criteria (which is very important) then the distance does go further out and there is also a lot of movement where people don't take places or leave during the year so even if you are on the waiting list initially (as we were) you do have a chance to get in. Of course, it is dependent on the number of siblings - the last two years has been high at around 20 but when we got our place it was around 12. We live about 800m away, we were 3rd on the waiting list and we got in and I know people who were 10th that got in - it might be literally in Sept when term starts but it is common. Obviously, if you can find somewhere, closer the better but just thought it would be helpful to give you some background as you can easily get (unnecessarily) put off.
