Seemingly deliberate undervaluing for what purpose? They have a property of mine showing an EPC rating of E, when it is in fact D. It has been D for well over a year. This was pointed out to them numerous times and they refuse to correct their mistake, and in the process they appear to be attempting to undervalue my (and presumably many other people's) property. As a lot of people use their website and try to get an idea of property value from doing so, and as they appear to deliberately do nothing about their inaccuracies, I am happy to arrange group legal action for other people also affected. Just go on twitter with hashtag #ZooplaLegalAction and I will keep an eye out for you.
