I’d just like to say a huge thank you for this website. I have just moved in to my first flat and was a bit stumped when NPower said they couldn’t give me a quote as I was on an E10 meter, I suppose that explains the 5 meter readings though! Was very thankful to find this website and get a very thorough and understandable explanation. Already had COOP tell me they no longer support the E10 but fingers crossed for OVO. Just glad I took the whole day off to deal with it!
