Your Questions Answered – Payments

We’ve been listening to your queries! Here, we answer some of the most common questions our customer service teams get asked.

How long will it take to set up my Direct Debit?

We will process a Direct Debit request the same day it is received (within business hours) and send your Direct Debit schedule to you the following day. This will detail when your next and subsequent payments will be taken. The first payment is usually taken around 3 weeks after we receive your request.

Why hasn’t my payment been allocated?

There are a number of reasons which stop us allocating a payment promptly. Some of these are:

  • an incorrect or missing account number
  • an incorrect or missing invoice number
  • your payment is part of a bulk payment for multiple accounts without instruction on which accounts to allocate the payment to

When you are making a payment to your Castle Water account, please make sure to accurately provide the following:

  • Your business name
  • Email address
  • Payment type (BACS, cheque, card etc)
  • Total payment amount
  • Account number(s)
  • Invoice number(s)
  • Tell us if you are making a single payment covering multiple accounts
  • Tell us if you are making multiple payments at the same time

You can use our remittance advice form if you are making a payment across multiple accounts.

The easiest way to ensure your payment is allocated quickly and accurately is to set up a Direct Debit.

I have received a late payment charge – which account does this relate to?

When we apply a late payment charge, a postal invoice is sent to you detailing this. The invoice also specifies the account number it relates to.

Can I get a copy of my late payment charge letter?

Yes – please contact us stating that you require an additional copy of your late payment invoice, providing your business name, email address, supply address and account number to ensure we send you the relevant document.

I am due a refund – where is it?

If your account is in credit, you can claim a refund by providing payment details here. If Castle Water has confirmed that a refund is due, this will be paid as quickly as possible but can take a little longer at peak times. If you have not received your refund within four weeks of your request or if you need it to be paid urgently, please get in touch.

I am struggling to pay – what support is available?

If you’re having financial difficulty, please get in touch as soon as possible – we’re here to help. If you’ve got a debt on your account, we may be able to help spread your repayments.
