Frequently asked questions for callers of the Npower contact phone number

Can I switch from paperless, back to paper bills?

Yes, any time you need to receive paper bills, just log onto your account online, go to your account settings and select “Online Service” and choose the paper bills option.

I don’t see my first bill online, where is it?

You will need to set up online billing. You can do this from your account online. Once this process is completed, you’ll be able to see bills online.

I want to switch, but the process is too difficult.

It is now easier than ever to switch your energy suppliers. Just let one of the advisors at customer care know, and you will be sent a welcome pack with your account details.

You will need to wait 14 days to register online (cooling off period), but your services won’t be affected.

I need help with my boiler?

Setting your thermostat at the wrong temperature could be costing you a lot of money in the long run. You can have a look at a handy instructional video online on how to get this right.

It might not always be your boiler that’s the problem, check your radiators for cool spots with a protective cloth so you don’t burn yourself. If you feel any cool spots or your upstairs radiators are taking a very long time to heat up, you need to bleed them. Call customer service or have a look at the tutorial video online to see how this is done
