Switch energy supplier online
Here are some of the things you can expect after switching to us:

Within the first 5 days
We'll send you a Welcome Pack and a copy of your contract. This will contain the details you have provided and your contract number, along with our Terms and Conditions.

You can use your contract number to create an online account and track your switch with Welcome Centre. It lets you see how you're progressing, read helpful information and send us an opening meter reading when you need to.

You've got 14 days to change your mind from the day you sign up, so check your information to make sure you're happy.

And remember, we'll contact your current supplier to tell them you're switching – you don't have to do a thing.

Once your switch is complete

Set up a Direct Debit
It’s simple to pay by Direct Debit. If you want to set one up, we’ll confirm the amount with you at least 14 days before your first payment is due.

Register for an online account
Once you’re all set up, you can activate your online account to look after your energy. Find out what you can do with one.

Get your vouchers
Please allow up to 8 weeks after you joined for any vouchers to arrive. If you switched through a comparison or cashback site, you’ll need to contact them directly.

Cancelling your contract
We give you a 14 day ‘cooling off’ period after you’ve joined us – if you want to cancel your contract during that time, you can.

Just call us:

0871 789 0365 from landlines

0871 789 0365 from mobiles

View call charge information

If you change your mind after the ‘cooling off’ period, you’ll still have to join us and we’ll ask you for some opening meter readings. You can choose to switch from us straightaway, but you’ll be with us for around 17 days while your
new supplier gets you set up.

You can change your mind once you’ve left us, but we’ll have to set you up with a new account – we can’t reactivate your old one.

We’ll send you confirmation around 7-10 days after we’ve cancelled your contract.

How do I submit a meter reading?
You can provide a meter reading at any time using our automated meter reading telephone service, please call us on 0871 789 0365.

Please have your account number to hand before calling. You'll find this on a most recent bill or letter.

If I have a question about the Nest Thermostat, who do I contact?
Information about the Nest products available from npower can be found here

If your question is about the installation of a Nest Thermostat, please contact the npower Nest Installs Team on 0871 789 0365.

Can I switch tariff or supplier if I have a Smart meter?
Yes. You're free to switch npower tariffs or switch to another supplier if you've had a Smart meter installed, in line with the terms and conditions of your current tariff.

Wherever possible your new supplier will make sure the smart functions of the meter, such as remote meter reading, are still available to you.

If you've had a Smart meter installed by another supplier you can still switch to npower as normal but for now we'll treat your meter(s) as a traditional meter and we'll send a meter reader to read your meter. You can also provide a
meter reading to us yourself. You can send us your reading online at or by calling us on 0871 789 0365.

Why am I receiving meter read reminders?
We want to make sure every bill you receive is as accurate as possible and based on either a meter reading you provide or a reading provided to us by one of our meter agents. To help make sure we can do this, our meter read reminder
service will let you know when the right time is for you to send us your meter readings.

Meter read reminders are one of the conditions of being on an online tariff and the reminders will have been turned on automatically when you entered into the contract.

For customers who are not on an online tariff , and where we have a valid email address or mobile number, we may have recently set up meter read reminders on your behalf, unless you have previously told us you do not wish to receive

How much energy have I used since my last bill?

If you pay for your energy after each bill, or by quarterly Direct Debit, you can find out how much you've used since your last bill by sending us a meter reading online.

If you've activated your online account, once you've sent a reading, we'll show the cost of your usage since you last paid a bill using our dial.

For the dial to work you need:
your last bill to be based on an actual reading, not an estimate
to have had at least one energy bill from us
to send meter readings in line with our predictions

I'm moving home - what do you need to know, and when?
If you're moving home we want to help make it go as smoothly as possible, which is why you can now tell us all about it online.

Just log in to or activate your account and we'll be able to close your old account and, if you want to take us with you, get you set up with a new tariff.

To sort out your energy online, you'll need your:

New address
Date you stop/start being legally responsible for the properties
Final meter readings (unless you have a Smart meter)
And if you want us to supply your new home, please make a note of which meters are installed before you come online.
