Affinity Water Pay Bill by Direct Debit
Direct Debit is the easiest and most popular way to pay your Affinity Water bill because the payment is taken automatically from your bank account on a fixed schedule. Once set up, you can make sure you pay your bill on time and without the hassle of remembering due dates or logging in to make manual payments each quarter.
Affinity Water lets you choose a Direct Debit payment frequency that suits your budget. You can pay monthly, every six months or annually. Monthly payments are the most common choice because they spread the cost evenly across the year, making it easier to manage household finances.
To set up a Direct Debit, log in to your Affinity Water My Account portal and follow the on-screen instructions. You will need your bank account number and sort code. You can also set up a Direct Debit by calling customer services on 03457 919 155 (Mon–Fri 8am–6pm, Sat 8am–2pm).
Affinity Water Pay Bill Online
If you prefer to make a one-off payment rather than setting up a recurring Direct Debit, Affinity Water has a dedicated website for paying your water bill online. The process takes only a few minutes and you can pay at any time of day or night, making it a quick and convenient option for customers who want to stay in control of when they pay.
To pay your Affinity Water bill online, you will need to have the following information ready:
- Your customer number (printed on your bill)
- Your postcode
- An email address
- A credit or debit card
Affinity Water accepts all major credit and debit cards except American Express. Payments made online may take up to 24 hours to appear on your account, so do not worry if the balance does not update immediately after you pay.
Affinity Water Pay Bill by Telephone
Affinity Water runs a 24/7 automated payment line on 0345 357 2400 that allows you to pay your bill at any time using a debit or credit card. The system is fully automated, so you will not need to speak to an adviser - simply follow the voice prompts and enter your customer number and card details.
This method suits customers who prefer to pay by phone but do not want to wait in a call queue. Because the line is available around the clock, you can pay early in the morning, late at night, or at weekends - whenever it is most convenient for you.
Have your customer number and payment card to hand before calling. The number 0345 is charged at the standard geographic rate and is usually included in mobile call bundles.
Affinity Water Pay Bill by Bank Transfer
You can pay your Affinity Water bill directly from your bank account using a one-off bank transfer or standing order. This method is useful if you do not want to share card details online or prefer to use your banking app to manage payments. Always quote your customer number in the transfer reference so Affinity Water can credit the right account.
Use the following UK bank account details when setting up the transfer:
| Detail | Value |

Affinity Water Pay Bill by Cheque
Customers who prefer postal payments can send a cheque made out to Affinity Water Ltd. While slower than digital methods, cheque payment remains an option for those without internet access or who simply prefer a paper trail. Bear in mind that it can take time for the cheque to arrive and clear, so post it well before the payment due date.
When paying by cheque, follow these steps to make sure your payment is processed correctly:
- Make the cheque payable to Affinity Water Ltd
- Write your customer number on the back of the cheque
- Include the payment slip from your bill
- Never post-date cheques or send cash
Post the cheque and payment slip to the following address:
Affinity Water Ltd
Tamblin Way
Hatfield
Herts
AL10 9EZ
Affinity Water Instalment Payments
If paying a lump sum is difficult, Affinity Water lets you split your bill into regular instalments - weekly, monthly or in two annual payments. Setting up a payment plan means you know exactly how much to pay and when, which helps with budgeting and avoids unexpected large bills landing on your doormat.
Monthly instalment customers can choose from four payment dates each month:
- 1st of the month
- 8th of the month
- 15th of the month
- 22nd of the month
You can make instalment payments using a payment giro book, PayPoint card, online, telephone or standing order. To set up a payment plan, visit the Affinity Water payment plan page on their website or call customer services.
Affinity Water PayPoint Card
When you set up a payment plan, you can request a physical payment card that allows you to make cash payments at any PayPoint outlet. PayPoint locations include convenience stores, newsagents and petrol stations across the UK. If your card is lost or damaged, contact Affinity Water to request a replacement.
Affinity Water Final Bill When Moving Home
When you move house, you will usually receive a final bill from Affinity Water covering your usage up to the date you leave the property. If you are moving to another address within the Affinity Water supply area, you may not need a final bill at all - your account can sometimes be transferred to your new address instead.
To avoid estimated charges on your final bill, submit a meter reading on the day you move out. You can do this through the My Account portal or by calling customer services. Our guide to Affinity Water moving home explains the full notification process step by step.
If your new home is outside the Affinity Water supply area, check who is my water supplier to find out which company covers your new postcode and how to register with them.
Struggling with Your Affinity Water Bill?
If you are finding it difficult to pay your water bill, Affinity Water offers several financial support schemes designed to help customers in hardship. You do not need to fall into arrears before asking for help - contacting Affinity Water early gives you the widest range of options and may prevent debt from building up.
The table below summarises the main support options available. Eligibility depends on your income, benefits status and household circumstances.
| Scheme | Who It Helps | Key Details |
|---|---|---|
| Payment Plan | Any customer | Splits your bill into affordable weekly or monthly payments |
| WaterSure Tariff | Vulnerable or high-consumption households | Caps metered charges; requires a water meter |
| Low Income Fixed Tariff | Earners under £16,385/year or benefit recipients | Caps clean water charges at a fixed annual rate |
| WaterDirect Tariff | Customers in arrears receiving qualifying benefits | Payments deducted directly from benefits |

If you live alone or have a small household, installing a water meter could also reduce your bill. Metered customers pay only for the water they actually use, which is often less than the unmetered flat rate.
