Baxi, Potterton, Vaillant, Worcester - which one is most reliable?

6am

I am going to replace my boiler. At the moment I have very old Potterton Ultra 2 with unvented cylinder. It does not work very well and I hate the fact that I need to wait a hour for water to heat and then it disappears very quickly. I want to remove unvented cylinder and replace conventional boiler with combi boiler. According to British Gas web site I have a choice of Baxi, Potterton, Vaillant, Worcester. Which one is most reliable? Thank you for your advice.

1. Worcester or Vaillant.

2. Get quotes from local gas installers, not BG - you'll save a small fortune!
