Thames Water Contact for Customer Service

You should call customer service when you are calling about your Thames Water bill, you want to query your account, or if you’re a new customer and want to speak to a representative to get registered with Thames Water.

When you call Thames Water customer service, you have two options:

  1. Pay a bill
  2. Anything else

To contact the Thames Water Customer Service team, call 0800 980 8800.

Option 1

This is a 24-hour automated line. The automated system is quite fast, so have this information ready to hand when you call:

  1. Thames Water customer account number
  2. Your credit or debit card details
  3. How much you want to pay in pounds and pence

It will ask you to enter your 10 or 12-digit Thames Water customer account number. You can find this at the top of your Thames Water bill or statement. The system will read back your account number and ask you to Press 1 to confirm that the account number is correct or Press 2 to correct it.

Next, you need to Press 1 to confirm that you are the account holder or have account holder privileges or authorisation. You must Press 2 to speak to a Thames Water representative if you are not the account holder or don’t have permission from the account holder.

Use Option 1 to confirm you are the account holder. You need to enter the amount you want to pay in pounds, then press the # key. Next, you need to enter the pence you want to pay, then press the # key. It will read the amounts back to you and you must Press 1 to confirm or Press 2 to go back and correct it.

If you want to pay £24.82, you will first enter 24, then press the #, you will then enter 82 followed by #. It will repeat the amount back to you. Press 1 to confirm the amount is correct.

You now need to enter your credit, or debit card details, to pay.

Option 2: Should your query be about anything else, you’ll need to Press 2. You will have three options:

  1. Account query
  2. Something else
  3. New customer

Option 2

This is for anything billing or account related. You will need to enter your account number and press 1 to confirm it’s correct or press 2 to re-enter it correctly.

If you want to speak to a Thames Water representative and avoid the robot-system, at this point do nothing. The system will repeat that you need to enter your account number. It will repeat this three times before transferring you to a Thames Water representative for help.

Option 2 is when your question is not about billing. Again, you will need to enter your Thames Water account number. If you don’t know it, you can Press # and give your house number and postcode by voice to the automated system and Press 1 to confirm after the system has repeated it.

If your house number is 27, you must say TWO-SEVEN and not twenty-seven. For your postcode, you must also say each letter and number one-by-one. For example: E11 7AB would be E-ONE-ONE-SEVEN-A-B and not E-ELEVEN-SEVEN-A-B.

Once you have entered your address details or account number, it then gives you four options:

  1. Moving house
  2. Update your contact details
  3. Information about your bill
  4. Report a leak or blocked drains

Once you have chosen from the above options, it will transfer you to a representative for help.

Option 3 is for new Thames Water customers who have moved into a property supplied by Thames Water. This option will transfer your call to a Thames Water representative who will help you register for an account.

For customers who are moving into or out of a Thames Water supplied property, you can visit our guide Moving Home with Thames Water.

  2. Leak inside your property

After choosing your option, you will need to say your postcode. It will then transfer you to a Thames Water representative.

Option 2

  1. Blocked roadside gully/storm drain
  2. Wastewater entering river or stream
  3. Any other issue about wastewater

Option 3

This for billing enquiries. Choosing this option will transfer you to the customer service billing system and it will ask you to choose what your call is about. Please see the options under Customer Service: 0800 980 8800.

Thames Water Complaints

If you’re having problems with Thames Water, for example, issues with your billing, account, or your water services, you can go through the Thames Water complaints procedure to resolve your problems. Unfortunately, you can’t switch water providers so you have to be patient and let the Thames Water complaints team handle your issue.

Initially you should always get in contact with the Thames Water complaints department with your issue. Depending on the nature of your Thames Water complaints, you can get in contact by phone through either of these two numbers:

Complaint Number Opening Hours
Billing & Account Problems 0800 980 8800 8am-8pm Mon-Fri
8am-6pm Mon-Fri
Water Service Problems 0800 316 9800 24/7

The Thames Water complaints team will try to resolve your issue as soon as you call. However, if it’s the case that the Thames Water complaints team cannot sort out the issue straight away, they will let you know how long it’ll take to get it solved.

Your wastewater might be with a different company! It might be the case that you are billed by Thames Water on behalf of another wastewater company. The name of the company is often detailed on your bill. If you have a problem with your wastewater service, you should contact that company.

If you're not happy with how the Thames Water complaints team have dealt with your complaint, you can of course ask them to review it.

If you are still unhappy or the Thames Water complaints team have not responded within 8 weeks, you can raise your complaint with the Consumer Council of Water (CCW). You can reach the CCW on 0300 034 2222.

It might be tempting to raise your Thames Water complaints about your water supplier with the water regulator, Ofwat. However, Ofwat does not deal with complaints about anti-competitive behaviour.

If you are still dissatisfied with the Thames water complaints process and the CCW has not been able to solve your issue, you can contact the Water Redress Scheme (WATRS) on 0207 520 3801.

Thames Water Water Meter Contact

Thames Water provides water meters for free. Thames Water is one of the few water companies that obligates a water meter installation for all its customers.

Thames Water generally instals smart water meters that send your water meter reading automatically over a wireless network. Customers will be given a year to compare their unmetered bill to how their bill compares with a meter and then they will be on a metered rate.

If you want to find out more, check out our Thames Water Meter guide.

Worried about your bill? People up and down the UK pay different water rates. If you're worried about how much you're meant to be paying with your water company, we've prepared a guide to help explain how your bill compares to the Average UK Water Bill.

  • Report a problem
  • No water or low pressure
  • Water hardness queries
  • Help with turning water on or off
  • Reporting flooding
  • Blocked drains
  • Plumber recommendations
  • Water meter issues

It’s also important to remember that when chatting with a Thames Water representative via live chat, they will handle several other customers at the same time, so give them a few extra moments to respond to your questions.
