npower Business Solutions customers can download the last 12 months of half-hourly data from the Meters section of Dashboard, its online account system. You can also request it by email from the Metering Team at nbssmart@npower.com.1,2
Dashboard: the Meters section
npower Business Solutions' Dashboard quickstart guide says the Meters section is where you submit meter reads, download consumption and view historical reads. You can search for meters by MPAN, MPRN (gas) or meter serial number.2
The option to use is "Download Half-Hourly (HH) data consumption". The guide says it gives "the last 12 months of HH data, or as far back as we have recorded if under 12 months".2
Asking by email
npower Business Solutions' metering page says you can request half-hourly data for your meter from the company that supplies you, and that its own customers should email the Metering Team at nbssmart@npower.com.1
Your right to the data
Since 1 December 2022, business customers with a smart or advanced (AMR) meter, and anyone they nominate, can ask their supplier for up to 12 months of their historic smart meter data, free of charge and in a machine-readable format. The supplier must reply within 10 working days, either giving access or explaining why not and what to do next.3
So even if an online portal doesn't give you what you need, you can ask for the file directly.
What to ask for
Ask for the half-hourly consumption data (kWh) for each meter, covering the last 12 months, as an Excel or CSV file. Quote each meter's MPAN, the supply number on your bill. Our guide to getting your data has a wording you can copy and a letter template (Word).
Check that the file has 48 readings for each day. A file of daily or monthly totals can't show the overnight and weekend patterns the analyser looks for.
