Scottish Power Review (August 2026)
Overview
Scottish Power has highly rated apps and strong Trustpilot reviews, but lower independent service scores mean it may not suit those who rely on phone support.
Who are Scottish Power?
Scottish Power is an energy company based in Glasgow. It was formed in 1990 and is now owned by the Spanish utility group Iberdrola. Today, it is one of the UK's largest domestic energy suppliers, supplying gas and electricity to millions of homes across the country. It also runs the local electricity network in parts of Scotland, Wales, and England.
What sets Scottish Power apart is its long-running partnership with Cancer Research UK, which it supports through specific charity tariffs. The supplier has raised £40 million for the charity since 2012. It also offers a range of products for the home, such as boiler care, solar panels, and electric vehicle chargers. Customers can also join a rewards club to earn points and save on their bills.

Prices
These are the tariffs we have pricing for — the supplier may offer others.
The supplier's lowest-priced option is its Standard variable tariff, currently estimated at £1,805 annually. This plan operates without a fixed term and does not charge an exit fee.
For households preferring price certainty, the Exclusive Help Beat Cancer Fixed Aug 2027 SM2 tariff is available. This 12-month fixed contract costs £1,990 per year and also avoids exit fees, though it sits at a higher price point than the variable alternative.

Customer Reviews
On Trustpilot, Scottish Power holds a rating of 4.4 out of 5 based on more than 198,000 reviews. Feedback leans positive, with 60% of users awarding five stars, while 19% leave one-star ratings. Data shows the supplier responds to 91% of negative reviews, generally within 24 hours.
Positive feedback frequently highlights polite staff and efficient account management, with users noting straightforward switching processes. Conversely, critical reviews often point to billing discrepancies, higher-than-expected charges, extended hold times, and complications during smart meter installations.
Independent assessment by Which? places Scottish Power at an overall score of 56. The supplier received 2 out of 5 for both overall customer service and value for money. Additional metrics include 4 out of 15 for complaints handling and 4 out of 10 for smart meter performance.
Apps
Account management is available via mobile applications for both Apple and Android devices. The iOS version holds a 4.8 rating from 86,000 users, while the Android version scores 4.7 across 95,000 ratings on the Google Play Store, reflecting over a million downloads. Both platforms receive regular updates.
Recent software updates indicate adjustments to the app's loyalty and energy tracking functions. A recent sample of iOS feedback points to a varied user experience; some customers appreciate the digital account tools, whereas others report inaccuracies with smart meter data and billing concerns.
Service & Support
In the latest Citizens Advice assessment, Scottish Power scored 2.94 out of 5, placing it 10th among suppliers. The data indicates an intake of 61.8 complaints per 10,000 customers.
Phone support data shows an average call centre wait time of 1 minute and 16 seconds. Digital communication is relatively fast, with 94.3% of emails receiving a response within two days. Accepted payment methods include Direct Debit, cash, cheque, and prepayment. Customer service phone lines operate from 9am to 5pm on weekdays and remain closed over the weekend.
The company has also registered formal vulnerability commitments with Citizens Advice to support eligible households.
Scottish Power complaints and performance
Figures for Q4 2025 show that Scottish Power received 1,458 complaints for every 100,000 customers. The supplier resolved 60% of complaints by the end of the next working day, and 86% within eight weeks.
Green Energy
Scottish Power focuses on generating its own renewable energy from UK wind farms. While the electricity it supplies to its standard domestic customers is largely fossil fuels, with a small amount of renewables, nuclear, and other sources, it offers specific green tariffs. For these tariffs, the supplier uses internal agreements to match the electricity its customers use with the 100% green electricity it makes at its own wind farms (Scottish Power).
The company also invests in home sustainability to help customers lower their carbon footprint. It installs green technology like solar panels and heat pumps to support the UK's net zero targets. Customers who get solar panels and batteries can earn energy credits as a reward for generating their own power.
Verdict
Scottish Power has highly rated apps and strong Trustpilot reviews, but lower independent service scores mean it may not suit those who rely on phone support.
Scottish Power may suit households who prefer managing their energy accounts digitally, given its highly rated mobile applications and generally positive Trustpilot feedback. The option to support Cancer Research UK through specific tariffs might also appeal to some consumers.
However, lower performance scores from Citizens Advice and Which? indicate that traditional customer service channels and complaint resolution can be inconsistent. Households that prioritise reliable phone support or high-scoring independent service metrics may want to evaluate other suppliers.

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.
