No t sure if this is the correct topic to respond to. I have a multi rate single phase watt hour meter which displays 3 numbers. how do I know waht two of the three numbers I need to submit. The videos on this subject do not cover this meter and no way to get in touch with Scottish Power. This is a very poor website we you cant even contact the supplier>
@Pollymac53 If you have smart meters an ihd should have been given to you. The ihd has to be installed by a fitter so you have to ask for that to be arranged. 0800 027 0072.
