Vaillant which is based in Remschied in the Ruhr in Germany bought a British company. Since then they have closed most of it down. They have an office in Belper, but there does not seem to be any management there.
They employ 300 gas fitters, but these do not report to any local offices. One of the fitters arrived three hours late, chewing gum and failing to introduce himself. He walked around the property to find something wrong and duly found a radiator leaking. He then declared the property dangerous and walked out. He blacklisted the property on the Vaillant computer system so they will not return
As it was 5 o clock it was pretty obvious that he wanted the rest of the day off. Neither he nor the man at the call centre will give out their names. It is impossible to get above the level of the call centre, which wastes up to 10 minutes of your time whilst it tries to get hold of the fitter to explain that you are complaining.
Whatever you may say, you will not be believed. This company has the gall to ask for pre-payment for service at the rate of £285 even for the most minor fault, which in my experience occurs frequently.
if you have similar problems your only recourse is to write to Dr Carsten Voightlaender at Vaillant GmbH, Berghauserstrasse 63, Remschied 42850 Germany. He understands english perfectly.
If he receives enough such letters he may come to realise that workshy attitudes - unknown to him in Germany - are destroying his UK business, where employment has plummetted, in recent years.
