First of all, it would help if you mentioned the type of hosting that you are looking for (e.g. Linux/PHP, Windows/ASP, Shared Server or Dedicated Server).
If it's PHP/MySQL that you are looking to host then Heart Internet look quite good and I believe that the Forum Editor is a reseller for Heart Internet.
Heart Internet have just introduced a Domain Privacy service as well, which looks interesting.
Have a look at the ISPA Awards website (see link below) for an independent opinion.
As I said, it all depends on what you need to host, but consider the following:-
