What’s the Utility Warehouse contact number for complaints?

The Utility Warehouse contact number for complaints is 0333 777 0777. This phone number will put you through to a member of the customer service team. Representatives are available Monday through Friday from 9 am to 5:30 pm.

We recommend you provide as much of the following information as possible:

  • Your name and contact details
  • Your account number
  • Background information on the issue
  • How you have been impacted
  • How you would like it resolved

A representative will aim to resolve your complaint within one working day. Customers who have written Utility Warehouse can expect a response within a day after the email or letter has been received.

If you are not satisfied with the proposed solution, you can ask to speak with a member of the Escalations Team. This representative will carry out an independent review, and they may refer the complaint to a manager or a specialist team.

If you still do not believe your complaint has been adequately resolved, you should request a deadlock letter from Utility Warehouse. This letter confirms that a mutually acceptable solution has not been found.

With the deadlock letter, you are then able to escalate the complaint to the Energy Ombudsman by calling 0330 440 1624 or sending an email to This is a free and independent service that will review the complaint.

If you do not have a deadlock letter, you can still take your complaint to the Energy Ombudsman if eight weeks have passed since you first raised the issue.

Emergency contact numbers

In the case of a gas or electrical emergency, you should not dial the Utility Warehouse contact number. We break down the emergency contact details below. Both of these emergency lines are available 24 hours a day, seven days a week.

Power cut

If you need to report a power cut or an electrical emergency, you should call your electricity network operator on 105.

If you experience a power cut, we recommend you take the following action (if possible):

  • Check the street lights to see if the issue is affecting other areas.
  • Go to your fuse box and check that the trip switch is on. If it’s not, attempt to reset the switch.
  • Turn off any sensitive equipment, such as a computer.
  • Keep your freezer closed. Some freezers can remain cold for up to 12 hours if kept unopened.
  • Check on your vulnerable neighbours to make sure they are warm and that any medical equipment is working.

Gas leak

If you smell gas or need to report a gas emergency, you should call the National Gas Helpline on 0800 111 999 immediately.

In the event of a gas emergency, you should do the following:

  • Put out all naked flames & turn off gas supply
  • Open windows and doors
  • Do not turn on or off electric switches
  • Do not use your landline or doorbell
  • Do not smoke

Other ways to contact Utility Warehouse

There are various other ways for you to reach out to Utility Warehouse besides just over the phone. Customers can also contact the energy supplier via email or Facebook.

To contact Utility Warehouse via Facebook, you must leave a comment on the page, as the supplier does not have the messaging service enabled.

Moving house

If you need to close a Utility Warehouse account, there are a few ways you can go about doing so.

If you’re moving to a new property, you will need to contact the supplier’s customer service department on 0333 777 0777. We recommend calling a day or two before you leave the current property. You will need to supply a final meter reading when you call.

If you are switching to a different energy supplier, the new supplier will take care of getting in touch with Utility Warehouse to close the account for you. We recommend hanging on to your final meter readings until the account has been completely closed and any remaining credit has been refunded.
