Scottish Power Complaints UK 2026: 8-Week Route to Resolution

LAST REVIEWED 2026-09-06

How do I complain to Scottish Power in 2026?

To complain to Scottish Power in 2026, contact their customer service team by phone, online chat, or post. The first step is to explain the issue and give them a chance to resolve it. Scottish Power must respond within 8 weeks of receiving your complaint. If they do not resolve it to your satisfaction, you can then escalate to the Energy Ombudsman.

The process starts with a clear description of the problem, including dates, account numbers, and any previous correspondence. Keep records of all contact. Scottish Power has a dedicated complaints team that handles issues such as billing errors, meter problems, and service failures. They aim to resolve most complaints within a few days, but complex cases may take longer.

If you are not happy with the initial response, you can ask for a review. Scottish Power should provide a final response letter, known as a deadlock letter, if they cannot resolve the issue. This letter is important because it allows you to go to the ombudsman. Without it, you may have to wait the full 8 weeks.

Check your complaint progress online or via the app. Scottish Power has improved its digital channels, but some customers still report delays. If you have a disability or need extra help, they offer a priority services register. Always note the date you first complained, as this starts the 8-week clock.

What is the 8-week rule for Scottish Power complaints?

The 8-week rule means that after 8 weeks from the date you first complained to Scottish Power, you can escalate the issue to the Energy Ombudsman. This is a legal deadline, not a target. Scottish Power has 8 weeks to resolve your complaint. If they fail to do so, or if you receive a deadlock letter earlier, you can go to the ombudsman.

The 8-week period starts the day after Scottish Power receives your complaint. It includes weekends and bank holidays. If Scottish Power sends a deadlock letter before 8 weeks, you can escalate immediately. The ombudsman will not accept a case before 8 weeks unless there is a deadlock letter.

After 8 weeks, you have up to 12 months to refer the case to the ombudsman. This is a separate deadline.

It is important to note that the 8-week rule applies to all energy suppliers in the UK. It is set by Ofgem and the Energy Ombudsman. If you are unsure whether your issue qualifies, contact the ombudsman for advice. They can confirm if you are eligible to escalate.

How do I escalate a Scottish Power complaint to the Energy Ombudsman?

To escalate a Scottish Power complaint to the Energy Ombudsman, you must first have either received a deadlock letter or waited 8 weeks from your initial complaint. The ombudsman is an independent body that resolves disputes between consumers and energy suppliers. You can submit your case online, by phone, or by post.

When you submit, you will need your account details, a summary of the complaint, and copies of any correspondence with Scottish Power. The ombudsman will review the evidence and may contact Scottish Power for more information. They will then make a decision, which is binding on Scottish Power but not on you. If you accept the decision, Scottish Power must comply.

The ombudsman can order Scottish Power to apologise, explain, correct a bill, or pay compensation. The process can take several months, but it is free for consumers. You do not need a lawyer.

Before escalating, consider whether you have exhausted Scottish Power's internal complaints process. The ombudsman expects you to give the supplier a reasonable chance to resolve the issue. If you escalate too early, they may ask you to wait until the 8-week deadline has passed.

What are common Scottish Power complaints in 2026?

Common Scottish Power complaints in 2026 include billing errors, inaccurate meter readings, problems with switching, and issues with the new online platform. Customers also report difficulties contacting customer service and delays in receiving refunds. Some complaints relate to the migration of accounts to a new system, which has caused confusion.

Billing errors can involve estimated readings, incorrect tariffs, or charges after switching away. Meter issues may include faulty smart meters or problems with readings. Switching problems often occur when the transfer is delayed or the final bill is wrong. The platform migration has led to login issues and missing documents.

Scottish Power has a responsibility to resolve these issues promptly. If they fail, customers can complain to the ombudsman. The company has been fined in the past for poor customer service, but it is working to improve. In 2026, the focus is on digital services, but some customers still prefer phone support.

To avoid common issues, keep a record of your meter readings and bills. Check your account regularly for errors. If you spot a problem, report it immediately. Scottish Power has a complaints procedure that should be followed. If you are not satisfied, escalate to the ombudsman after 8 weeks.

What is a deadlock letter and when do I get one?

A deadlock letter is a final response from Scottish Power stating that they cannot resolve your complaint. It is also known as a 'final response letter'. You should receive one if Scottish Power believes they have done everything they can. The letter explains that you can escalate to the Energy Ombudsman.

Scottish Power should send a deadlock letter if they reject your complaint or if you reject their proposed solution. They may also send one if they have not resolved the issue within 8 weeks. The letter should include details of the ombudsman and how to contact them. If you do not receive a deadlock letter, you can still escalate after 8 weeks.

If you receive a deadlock letter, you have 12 months to refer the case to the ombudsman. The ombudsman will then investigate. The deadlock letter is not a refusal to help; it is a formal step in the process. It allows you to seek an independent review.

Keep the deadlock letter safe, as you will need to reference it when submitting your case. If Scottish Power does not send a deadlock letter but the 8-week deadline passes, you can escalate without one. The ombudsman will accept your case as long as you have given Scottish Power enough time.

What are Guaranteed Standards of Performance for Scottish Power?

Guaranteed Standards of Performance (GSoP) are minimum service levels that energy suppliers must meet. If Scottish Power fails to meet these standards, they must pay you compensation automatically. Examples include failing to respond to complaints within 8 weeks, missing appointments, or not restoring supply after a fault.

For complaints, the standard is that suppliers must resolve them within 8 weeks. If they do not, they may be in breach. For other failures, the amount varies. Scottish Power must pay compensation without you asking, but you may need to remind them.

If you believe Scottish Power has breached a GSoP, you can complain. They must investigate and pay compensation if applicable. If they refuse, you can escalate to the ombudsman. The ombudsman can enforce GSoP payments.

GSoP are set by Ofgem. They cover areas like billing, switching, and complaints. In 2026, the standards remain in place. Check the Ofgem website for the full list. If you experience a service failure, keep records and report it.

How does the Scottish Power platform migration affect complaints?

The platform migration refers to Scottish Power's move to a new customer management system. This has caused issues such as lost documents, incorrect bills, and login problems. Customers have complained about being unable to access their accounts or receiving duplicate bills. Scottish Power has acknowledged these issues and is working to fix them.

If you are affected by migration issues, contact Scottish Power immediately. They should be able to correct errors and provide compensation if you have been inconvenienced. Keep records of any problems, as you may need them for a complaint. The migration has also affected the speed of customer service responses.

Scottish Power has said that the migration will improve services in the long run. However, in the short term, it has caused frustration. If you have a complaint related to migration, follow the normal complaints process. If it is not resolved within 8 weeks, escalate to the ombudsman.

To resolve migration issues, check your account online for errors. If you cannot log in, use the phone or chat. Scottish Power may ask for verification. Be patient, but persistent. If the issue is serious, such as a wrong bill, ask for a deadlock letter so you can escalate.
