Save yourself the aggravation and go to another company
Right Gas installed a new boiler, after Domestic & General sent them to assess a problem with our old boiler, which they said was irreparable.
After leaving a big part of the house without functioning radiators, they insisted a power flush was needed, which they wanted to charge a further £700 to do.
We called another company that we trusted, as suggested by D&G, (but who hadn't been able to replace the boiler quickly enough) to review what Right Gas had done and see if they were right about a flush being necessary.
A simple re-balancing of the radiators fixed that problem. So much for a £700 power flush being needed! Right Gas could have re-balanced the radiators but thought they could get more money out of us.
However, Right Gas had also failed to do a number of things that they should have done:
1. As part of the boiler installation they recorded on the paperwork that they had done a chemical flush of the system and then added inhibitor. The new plumber that came tested for inhibitor and found less than 10ppm inhibitor in the system only three weeks after Right Gas had supposedly added it.
2. Right Gas had terminated the condensate disposal into the rainwater without an air break and without clarifying if we have a combined foul and rainwater system, as per BS6798.
3. Right Gas either chose to ignore or failed to see that the open vent pipe and feed, and expansion pipe did not rise continuously from the boiler, and that a valve was fitted there when it shouldn’t have been, as per the manufacturer’s instructions. Yet they proceeded to install the boiler despite these serious issues. Whether not seen or just ignored, either way it was completely unacceptable.
4. Right Gas stated on the official commissioning paperwork that the gas valve inlet test point had a reading of 18.91 (without any other gas appliances on, which they are supposed to be). We watched it being tested and showing a reading of 15.5-16. They had entered a hugely incorrect figure. Not even close.
We are taking this up with Gas Safe and Trading Standards.
Save yourself the aggravation and go to another company.
