Ways to pay your bill

The most convenient way to pay your bill is by Direct Debit, but there are other options too. Find what works for you, and if you're having problems with an upcoming payment, get in touch so we can support you.

Pay by Direct Debit

Direct Debit is the easiest way to pay your bill, and saves you £5 a month. Once set up, your monthly bill will automatically come out of your account between 19 and 30 days after your monthly invoice date.

First, clear outstanding payments

To set up your Direct Debit, you must first clear any outstanding payments on your account. You can make this one-off payment following these steps.

Before you set up a Direct Debit

If you’re not a sole trader, the Direct Debit must be in the name of the business and signed by at least one account administrator. This can be done using the Direct Debit mandate instructions.

Schools and other services registered under their own name, but whose invoices are paid through the parent local authority, must provide evidence of the link before a Direct Debit can be set up.

Use your card to set up a Direct Debit online

1. Log in to your Three Business Account using your Three Business mobile phone number and password

2. On your account page select ‘Manage auto-renewals’


3. Select ‘Bank account’ and fill in the account holder name, sort code and account number for the account you want the Direct Debit to be set up from


4. Save the payment details

Setting up your Direct Debit on the Three app

  1. Log into your account on the Three app
  2. Go to ‘Manage auto-renewals’
  3. Select the ‘Direct Debit’ option and fill in the account holder name, sort code, and account number for the account you want the Direct Debit to be set up from
  4. Save the payment details

Setting up your Direct Debit by post

  2. Print it out
  3. Fill in all required details
  4. Send to the below address

Address : Three Business Services, PO Box 333, Glasgow, G2 9AG

If your bank requires more than one signature to authorise transactions, you’ll need a Direct Debit mandate. Just follow the above steps.

Set up a Direct Debit via online chat (chat to us Monday-Sunday 7am to midnight)

  1. Open up our online chat (found in the bottom right of your screen)
  2. Select ‘I need business help or support’
  3. Select ‘Chat to an expert’
  4. You’ll then be asked a series of questions and will need your mobile phone and account numbers before chatting with an agent

As with all methods of setting up a Direct Debit, any outstanding Three Business payments must be cleared before our agents can help you.

Cancelling or making changes to your Direct Debit

You can cancel your Direct Debit at any time using one of the below options:

If you cancel your agreement with us within 3 days of your billing due date, we will still deduct the outstanding balance. To prevent potential fees from your bank, it's advisable to get in touch with them to explore alternative solutions.

When you cancel a Direct Debit, you must settle your bill in its entirety.

Things you should know about cancelling your Direct Debit

  • If you choose to cancel directly with us, but do so within 3 days of the deadline, we will still collect the outstanding balance. To prevent potential fees from your bank, reach out to them to explore possible alternatives.
  • Upon cancellation of a Direct Debit, you'll need to settle your bill in its entirety.
  • A payment can't be cancelled within 48 hours of its due date. You must cancel at least 3 days before the billing date.
  • If you stop your Direct Debit or monthly card payments, you will need to pay your bill using a different method. Additionally, you will forfeit the £5 monthly reduction.

Things you should know about changing your Direct Debit

  • You can't change your payment date within 48 hours of your payment due date.
  • Altering your payment date is only possible once you're received your first invoice.
  • You need to contact us to change your Direct Debit payment date.
  • By adjusting your payment date, the timing of your bills will also shift. This will result in your next few bills being more closely spaced than usual.
  • Before changing your payment date, ensure that your new price plan is in place.
  • Keep in mind that you can only modify your payment date once between billing cycles.
  • By changing your payment date, it will generate a pro-rata charge.
