In the UK, companies often run a credit check before providing credit to customers. This might happen when you apply for a loan, or a new mobile phone. 

Utility companies also use credit checks because most homes receive their energy on credit. Unless you have a prepayment meter, you’re probably using energy on credit - meaning you use the energy first, then pay the bill afterwards. 

When you register with Octopus, we’ll ask for your permission to check your credit data with TransUnion. That means we’re obligated to provide information back to TransUnion, such as data on your payments with us, which ensures that your credit score stays up-to-date. 

At the end of each month we share information with Transunion to update their records. It can take up to two weeks for any changes in your credit score to be reflected on third party sites like Credit Karma. 

We want to make sure our customers don’t end up in a position where they’re unable to cover any debt or missed payments on their account. If you do miss a payment, then a late payment marker could be added to your report, which can then negatively affect your credit score. If you’re struggling to pay for your energy, 

Regular late payments will have a longer lasting impact on your credit score (which could make it more difficult to get accepted for other credit like loans or mortgages) and the report can stay on your credit records for up to six years.

All accounts joining us from Bulb will have their information shared with TransUnion. Making regular payments on time should positively impact your credit score. If you miss payments or regularly pay late, then your score will be negatively affected as outlined above.

What is credit data sharing?

' is a credit balance. This means if you left Octopus tomorrow - and your bills were up to date - we'd refund you this money to take your balance back to £0.

' is a debit balance. This means if you left Octopus tomorrow - and your bills were up to date - you'd need to pay us this amount to bring your balance back to £0.

 and we’ll send you a statement within a few days. If you don’t send us readings, we’ll send you an estimated bill every three months.

We do it this way because we want to avoid estimating your energy usage where possible. Real meter readings make your statements a lot more accurate. There’s more information about

It's common for your old supplier to offer a better deal to try and stop you from switching. Before accepting, ensure it's as good as they say by asking the following questions:

1. What are the unit rates and standing charge?

Check your old supplier's unit rates and standing charge are cheaper than ours, as some suppliers may reduce your monthly Direct Debit without reducing the actual price of your energy. This could result in you building up a substantial debit with them.

Your old supplier might also divert your attention from unit rates to the standing charge, especially if theirs is cheaper than ours. But please bear in mind that standing charges have a much smaller impact on your energy cost than the unit rates.

2. Can I have full tariff information, including the annual usage estimate?

Not only will this show unit rates and standing charge, but you'll be able to see what annual usage estimate they've calculated savings on.

We use the estimate you gave us, or Ofgem's Low, Medium, High values (as indicated by you). Your old supplier's usage estimate might be different, meaning your payments might not be enough for your usage.

3. What tariff will I default to once the cheap deal ends?

Many suppliers will move you to an expensive tariff once a cheap one ends, in the hope you'll forget to switch. We covered this in 

. This might be alright if you're a regular switcher, but if you're after long-term value you'd be better sticking with us.

We pass savings to customers however we can, and different methods of payment are more expensive for us to manage. 

Not having a Direct Debit (and instead Paying on Receipt of your Bill) costs us more in admin and managing your account. We don't think it's fair to make everyone cover that extra cost, so we sometimes have cheaper rates for those who choose to pay by Direct Debit. 

Because we operate a lean and efficient business you’ll still get a great price if you choose to pay a different way.

Why are tariffs sometimes cheaper if I pay by Direct Debit?

We take this first payment to make sure your account opens in credit. It acts as a bit of a buffer so that if you're using more energy than we expect, your account won't fall into debt early on. You'll be able to adjust your payment in your account once we have more information about your usage.

Why do you take an initial payment when my supply starts?

When you switch to us, we ask for an opening meter reading to send to your old supplier so they can close your account and issue a final bill. On the way over, your reading goes through a series of third–party checks to ensure your old supplier agrees with it.

Sometimes, your old supplier might tell you we haven't sent them the reading. This is normally because the readings are still being checked, or your old supplier has yet to agree them.

Since your old supplier is responsible for issuing your final bill, we can't say for certain when you'll get it, but from our experience it usually happens in four to six weeks.

What extra support is available to customers in vulnerable circumstances?

If you’re in credit, your old supplier will transfer the credit directly to your bank account once you’ve received your final bill.

If you’re in debit, you need to clear it as soon as possible, otherwise they might object to your transfer (which can cause severe delays to your move). If you’re having trouble paying, you can ask for a payment plan, which will still allow you to switch.

What happens if I'm in credit or debit my old supplier?

Some suppliers will charge you an exit fee for leaving your contract early but an important note on this — if you apply to leave your old supplier within 49 days of the end of your contract, they are not allowed to charge you any exit fees. You can see a more detailed explanation on the energy regulator 

. The bit you need to know is highlighted below:

"Suppliers will be required to notify customers that their current fixed-term is coming to an end between 42 and 49 days before the contract ends.

Between this notification period and the end of the fixed term contract, suppliers will be banned from charging a termination fee should the customer decide to switch."

Will I be charged cancellation fees?

Although you'll never have to pay twice for the energy you use (any overpayments are always refunded), you could find yourself with two active Direct Debits until your old supplier closes your account.

To avoid this you could cancel your old supplier's Direct Debit. This does mean that any closing credits or debits have to be made another way – by cheque, for example – so it's worth thinking about the impact of the cancellation before deciding to do it.

 What payment methods do you offer?

When you first join us, we calculate your Direct Debit amount based on the information you give us in your quote. We take your expected energy usage for the next 12 months, work out the cost, and divide it by 12 so you’re spreading your energy costs over the whole year. 

We receive your meter’s historical usage information from your previous supplier once your switch is complete, which gives us a much more accurate idea of how much energy you use. If you don't have a smart meter, you can make sure your payments are as accurate as possible by

I need help with my energy bill

Octopus Energy will take your first Direct Debit on the date we start supplying your energy, and every month on the day you've asked us to. We estimate your annual usage when you join us, so having some credit when your account opens can help while we learn more about your energy consumption. 

When will my first Direct Debit go out?

At the moment, you can earn cash back with a Santander 123 account. For other accounts, please get in touch with your bank and ask them to include us. Once they agree, let us know.

Most people use more energy in winter and less in summer but pay the same amount each month via Direct Debit. That means your balance can vary throughout the year as you build credit over the summer to help offset higher winter bills. 

If you pay by monthly Direct Debit and are on a standard Fixed or Flexible tariff, our
