Availability: General telephone support is available Monday to Friday from 8:00 AM to 8:00 PM, and Saturday from 8:00 AM to 5:00 PM (UK Time). The standard customer service phone lines are closed on Sundays. (Note: The emergency loss-of-supply line 0345 2068 999 is open 8:00 AM to 10:00 PM daily).
-
Timeline: Utilita aims to resolve complaints quickly. If they cannot resolve it within 5 working days, they will formally acknowledge it and keep you updated. (Note: Under Ofgem rules, if an engineer misses an appointment or they are late switching your supplier, they must issue automatic compensation credits to your bill).
Level 2: Formal Corporate Escalation (Notice of Dispute)
-
Who to contact: If standard customer service cannot resolve the issue, you must formally escalate it to their central correspondence team. Send a written letter detailing your account number, a timeline of the issue, and your desired resolution. You must explicitly request a “Deadlock Letter” if they refuse your proposed resolution. Sending this via Royal Mail Signed For is highly recommended to prove receipt, even though it is a Freepost address.
-
Complaints Address: Freepost RTXA-BEUG-KLGH, Utilita Energy Limited, Hutwood Court, Bournemouth Road, Chandler’s Ford, Eastleigh, SO53 3QB
-
Timeline: Under Ofgem regulations, Utilita has a maximum of 8 weeks to issue a final resolution or a Deadlock Letter.
Level 3: Regulatory Authority (Government Ombudsman)
-
Authority: The Energy Ombudsman
-
Portal/Contact: The Energy Ombudsman is the Ofgem-approved, free dispute resolution service for Utilita Energy complaints. You can submit a complaint online or by phone:
-
Website: energyombudsman.org
-
Email: enquiry@energyombudsman.org
-
Phone: 0330 440 1624
-
Timeline (CRITICAL): You can only refer your complaint to the Ombudsman after you receive a Deadlock Letter from Utilita, OR if 8 weeks have passed since your initial formal complaint without a resolution. You must escalate the complaint to the Ombudsman within 12 months of receiving your Deadlock Letter.
Level 4: Legal Action (Final Step)
-
Pre-Litigation: Before commencing legal proceedings, UK legal protocols require you to send a formal “Letter Before Action” (LBA) to Utilita’s corporate legal headquarters. This letter must outline your claim, the exact legal or contractual breach, the evidence, and the financial remedy you seek, giving them a final 14 to 30 days to settle.
-
Legal Address: Utilita Energy Limited, Hutwood Court, Bournemouth Road, Chandler’s Ford, Eastleigh, SO53 3QB
-
Court: If the LBA fails and the Ombudsman cannot resolve it, you can file a lawsuit. For financial claims up to £10,000 in England and Wales, you can use the Money Claim Online (MCOL) portal to enter the Small Claims Track. For complex claims, you will likely need to instruct a solicitor and proceed to the County Court.
