System Boiler recommendation

[Creampastry]

Our system boiler has just been condemned, allegedly due to the actions of the beep beep "plumber" who services it ..... Grrrrr.... I'll deal with him but in the meantime, I would appreciate any recommendations for a system boiler.

Why has your boiler been condemned? I like vaillant and dislike worcester, however I work in the industry and find vaillant much easier to work on.

I have a Wocester and my mum has a Vaillant, both have been great.

Thanks, will look at both.
