January this year a water pipe burst in the kitchen directly over a Belling Range cooker (some 13+ years old). Switched it off at the mains and awaited a visit from an electrician once the place had dried out.
The sparky that arrived had worked for Belling, was very familiar with their products. He checked it over, tested, declared it safe. He then added that if something had been wrong I would have been better to get parts replaced rather than a complete new oven - because Belling products these days are much less reliable.
I have no data on that, but I can't but believe someone in the industry.
