You can get a reminder of your login details by entering your email address here: https://www.npower.com/At_home/Forms2/MyNpower/EmailUserId.aspx?workflow=Email+User+Id - we'll then send your user ID and a password reminder. Remember you can send a meter reading online at any time, with or without your login details. If you don't log in, you'll just need to enter your surname, postcode and account numbers to send a meter reading (if you log in we remember these details for you). As the meter readings are from your old house, please enter your old account numbers and postcode when you send in your exit meter readings.
