Those are some of the few I'm aware of in East Sussex as I've stumbled across them when searching for walkon sites.
Also, take a look at this site, http://www.uk-active.co.uk/paintballing/paintballingwtgmain.htm this is where I found the three I've mentioned and see if any others are near you. You may want to give some of the sites a call to check about the walkons to make sure they actually hold one or not. Because sometimes they don't mention it on their website.

Sorry to say demolition paintball has no walk on sites, i marshal at their brighton site which is situated between brighon and smalldole and they used to have a walk on there but have stopped due to low numbers of people turning up, if there are many people looking for a walk on site in brighton area please reply to this post and ill see if i can try and organise a walk on day with demolition paintball on their brighton site, need a reasonable number of people (10+).
