Customer reviews
On Trustpilot, Scottish Power holds a rating of 4.4 out of 5 from over 192,000 reviews. The distribution shows 60% five-star ratings alongside 20% one-star ratings.
Positive feedback frequently highlights staff patience and helpfulness when resolving complex account issues. Reviewers also note clear communication and an accessible user experience. Conversely, negative reviews often cite concerns over pricing, unexpected account changes, and missed engineer appointments.
Independent survey data from Which? awards the supplier an overall score of 56. Category results include 2 out of 5 for both customer service and value for money, 4 out of 10 for smart meters, and 4 out of 15 for complaints.
Apps
Account management is available through the Scottish Power mobile apps, which hold strong ratings across both major platforms. The iOS version scores 4.8 from 85,000 ratings, while the Android app holds a 4.7 rating from over 94,000 reviews and exceeds one million installs on the Google Play Store.
Software updates are released regularly for both operating systems. A recent Android update introduced an Energy Tracker feature specifically for Direct Debit customers. Meanwhile, a sample of iOS feedback indicates users find the interface practical for processing top-ups and monitoring smart meter usage.
Service and support
Citizens Advice assigns Scottish Power a score of 2.94 out of 5, ranking it 10th among UK suppliers. The data also shows an average of 61.8 complaints per 10,000 customers.
Phone support data indicates an average call centre wait time of 1 minute 16 seconds. For digital correspondence, the supplier responds to 94.3% of emails within two days. Customer service lines operate on weekdays between 9am and 5pm, remaining closed on weekends. Accepted payment methods include Direct Debit, cash, cheque, and prepayment.
To support households requiring additional assistance, the supplier maintains formal vulnerability commitments registered with Citizens Advice.
Scottish Power complaints and performance
In the most recent period available (Q4 2025), Scottish Power received 1,458 complaints for every 100,000 customers. The supplier resolved 60% of these complaints by the end of the next working day, and 86% within eight weeks.
Green energy
Scottish Power's parent company, Iberdrola, runs wind farms across the UK to generate renewable electricity. Despite this, the actual electricity mix Scottish Power supplies to its domestic customers is largely fossil fuels, with a small amount of renewables, nuclear, and other sources.
The company funds environmental and community projects across the UK through the Scottish Power Foundation. It also takes part in government schemes like the Energy Company Obligation and the Great British Insulation Scheme to help upgrade homes and improve energy efficiency.
Verdict
Scottish Power offers highly rated apps and strong Trustpilot reviews, but its independent customer service scores from Which? and Citizens Advice are low.
While Scottish Power provides highly rated digital tools and maintains a strong Trustpilot profile, its performance in independent assessments is less competitive. The supplier currently holds a Citizens Advice score of 2.94 out of 5 and received low customer service ratings in the latest Which? survey.
This supplier may suit households that prefer self-service account management through a mobile app. Conversely, customers who prioritise high independent service scores, strong phone support, or clear billing practices might consider comparing alternative providers.

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
