Pros & cons
What we hear from Scottish Power customers
Strengths
- 100% renewable electricity on every domestic tariff (REGO-backed) since 2018, when Scottish Power became the first UK vertically integrated power company to sell off its fossil-fuel generation.
- Trustpilot score of around 4.3 of 5 across roughly 180,000 reviews, an "Excellent" volume score that rivals British Gas and E.ON Next for sample size.
- Joint 1st of the large UK suppliers for Ease of Contact in the Citizens Advice supplier-performance table (Q4 2025 release): 4 of 5 stars on call wait times, ahead of most Big Six peers.
- Cap Tracker tariff knocks around £7.50 per fuel per year off the standing charge versus the Standard Variable Tariff, with no exit fee — a free lunch for engaged customers who do not want to fix.
- Big Six scale: 7-day phone cover (Mon-Sat), 24/7 gas-emergency line, dedicated boiler-emergency line and an in-house Hardship Fund for customers in fuel debt.
- Strong specialist EV proposition: EV Saver at 8.50 p/kWh overnight (midnight to 5 a.m.) plus the EV Optimise smart-scheduled add-on, both backed by ScottishPower's own renewable generation.
Weaknesses
- Ranked last (17th of 17) in the Which? 2026 Energy Companies survey with an overall score of 56%, the lowest of any UK supplier surveyed. Customer-perceived complaint handling is the single weakest score.
- Citizens Advice gives Scottish Power only 2 of 5 for complaints handling (Q4 2025): the brand resolves contact-stage queries quickly but is weaker once a case is formally logged as a complaint.
- Historical Ofgem fines: £18 million in 2015 over poor customer service and complaint handling, and a 2018 Ofgem investigation into customer-service practices. Both still surface in older comparison content.
- No dedicated heat-pump tariff on the price sheet (unlike Octopus Cosy, EDF Heat Pump or E.ON Next Heat Pump), so households that have replaced a gas boiler with a heat pump pay the full Standard or Fixed unit rate.
- EV Saver and EV Optimise both require a SMETS2 single-rate smart meter sending half-hourly data; SMETS1 meters and two-rate / Economy 7 setups are not eligible without an upgrade.
Selectra verdict
Our independent take on Scottish Power
Scottish Power is one of the more operationally polarised Big Six brands in the UK market in 2026. The brand is best-in-class on green credentials (100% renewable electricity, the largest UK Iberdrola-backed wind portfolio) and on call-wait times, with a 4.3 Trustpilot score across roughly 180,000 reviews. But the same brand sits dead last in the Which? 2026 survey and Citizens Advice continues to give it just 2 of 5 for complaint handling.
The practical playbook for a 2026 Scottish Power customer is: switch off the Standard Variable Tariff onto the Cap Tracker as soon as the first bill lands (free £15-£25 a year saving with no downside), apply for the Hardship Fund the moment arrears appear, escalate to the Energy Ombudsman after eight weeks if a formal complaint stalls, and use the EV Saver tariff if you have a SMETS2 meter and an EV. Households who want a heat-pump-specific tariff or rank-best customer service in the Which? table should weigh up Octopus, Good Energy or E.ON Next as alternatives.

Cap Tracker switch took two clicks
Was on the Standard Variable Tariff and noticed the Cap Tracker on the website. Same unit rate as the cap, lower standing charge, no exit fee. Switched in the YourEnergy account in two clicks — bill is now £20-odd a year cheaper for literally zero effort.
— Claire, Glasgow
Trustpilot
Selectra expert comment
The Cap Tracker is the highest-leverage one-click switch in the Scottish Power book. It uses the same unit rate as the cap so you keep all the upside if wholesale prices fall, but locks in a permanently lower standing charge. Always do this move from inside the YourEnergy account rather than over the phone — the in-account switch processes the next billing cycle, the phone-line switch can take up to 14 days.
EV Saver is the real deal
SMETS2 meter went in last spring, signed up to EV Saver in May. Charge the car between midnight and 5, run the dishwasher overnight, run the washing machine at the weekend. First annual bill came in £540 lower than the Standard Variable would have been on the same usage.
— Mark, Birmingham
Google reviews
Selectra expert comment
A textbook EV Saver load-shift case. Households running an EV plus a heat pump or storage heaters can compound the saving by also moving those loads into the 00:00 to 05:00 window. Verify the SMETS2 meter is genuinely sending half-hourly reads before signing — Scottish Power runs an eligibility check, but it is worth confirming inside the YourEnergy app first.
Hardship Fund actually came through
Lost shifts last winter and fell behind on the gas. Applied to the Hardship Fund, was assigned a caseworker who walked me through the form, and a grant cleared the arrears within a month. No judgement, no chasing.
— Sandra, Edinburgh
Trustpilot
Selectra expert comment
The Scottish Power Hardship Fund is a genuine supplier-funded grant pot, not a payment plan. Apply before you cancel your direct debit — active customers in arrears are prioritised over those who have already gone "no payment". Have proof of household income and recent bank statements ready when you submit the application.
Complaint stuck in limbo for nine weeks
Logged a formal complaint about an estimated bill in May. Three goodwill credits and four "we will call you back" promises later, no resolution. Took it to the Energy Ombudsman in week ten and the case was decided in my favour within a month.
— Daniel, Cardiff
Citizens Advice complaint
Selectra expert comment
Citizens Advice scores Scottish Power 2 of 5 on complaints handling, and this review is a textbook example. The eight-week clock matters: if a formal complaint is not resolved by week 8, you can escalate it to the Energy Ombudsman for free. The Ombudsman's decision is binding on Scottish Power. Always log the complaint in writing (email, in-app message, or the formal complaints address in Glasgow) so the eight-week clock has a documented start date.
YourEnergy app is good, not great
App handles the basics well — bills, meter reads, DD changes, tariff switches all work in two or three taps. Half-hourly smart-meter data is there once the SMETS2 is paired. Push notifications occasionally late by a day or two but nothing serious.
— Helen, Manchester
Apple App Store
Selectra expert comment
The YourEnergy app sits in the upper half of UK Big Six apps for usability — slightly behind the Kraken-based E.ON Next and Octopus apps, slightly ahead of the legacy British Gas and EDF apps. For tariff switches and DD changes, prefer the app to the phone line; processing time is materially shorter and confirmations land in writing the next day.
Smart meter install booking — first slot was three months out
Booked a free SMETS2 install through the website. First available slot was three months out, then the engineer rebooked it twice. Once installed it works fine and reads half-hourly, but the booking journey was painful.
— Patricia, Liverpool
Trustpilot
Selectra expert comment
Smart-meter install lead times at Scottish Power are typically longer than at Octopus or E.ON Next during peak winter rebooking. Ask for the in-app SMS slot reminder when you book, take a final read off the legacy meter on the day of the install, and screenshot it — it makes the cutover bill cleaner. If the engineer no-shows twice, ask for a £30 goodwill credit under the Guaranteed Standards of Performance scheme.
Selectra editorial takeaway
Reading the reviews together
Reading the eight reviews together, Scottish Power presents the classic "two-speed Big Six" pattern. The brand is genuinely strong on the things it controls operationally end-to-end — green credentials, the YourEnergy app, the EV Saver tariff, the Cap Tracker switch, the Hardship Fund and call-wait times. It is genuinely weak on things that require multiple internal teams to coordinate over weeks — formal complaints, estimated-bill resolution on smart meters with poor DCC signal, and engineer rebooking at peak.
The practical playbook is to do the easy upgrades (switch to the Cap Tracker the day the first bill lands; sign up for EV Saver if you have a SMETS2 and an EV; apply to the Hardship Fund the moment arrears appear) and escalate hard on anything that stalls: any formal complaint that has not been resolved within eight weeks goes free of charge to the Energy Ombudsman, whose decision is binding on Scottish Power.
Selectra explains
Scottish Power's online presence: expert analysis
Author: Selectra UK energy team · Updated May 2026
Scottish Power has, by mid-2026, one of the most polarised online review profiles in the UK Big Six. Trustpilot and the Citizens Advice ease-of-contact subscore are top-quartile; the Which? 2026 survey ranks the brand last; the Google and app-store scores sit somewhere between the two. Public signals diverge most clearly on complaint handling: agents resolve simple contact-stage queries quickly, but formal complaints get stuck materially more often than at peer suppliers.
Channel
Trustpilot
4.3/5
around 180,000 reviews
One of the highest-volume Trustpilot scores in the UK energy retail market. Most-mentioned positives are friendly agents, the Cap Tracker switch and quick first-bill turnaround. Negatives concentrate on estimated bills, smart-meter install rebooking and stuck formal complaints.
Channel
Google reviews
3.7/5
around 6,800 reviews
Google scores sit a step below Trustpilot because Google captures more unprompted complaint reviews and fewer review-invite responses. Common themes: stuck formal complaints, estimated bills on weak-signal smart meters, and slow phone response at peak.
Channel
Citizens Advice supplier performance
3.1/5
Q4 2025 release (March 2026)
Ranked 3rd of the large UK suppliers for the period, but with sharp internal divergence: joint 1st on Ease of Contact (4 of 5 on call wait times) and 5 of 5 on the Vulnerability Commitment, but only 2 of 5 on complaints handling.
Channel
Which? Energy Companies Survey
Lowest (56%, ranked 17th of 17)/5
2026 release
Ranked dead last in the Which? 2026 survey of UK energy suppliers, with the lowest customer-perceived score for complaint handling. Useful counterweight to the Trustpilot headline number — Which? captures perception of the brand as a whole, not individual ticket outcomes.
Channel
Apple App Store (YourEnergy app)
4.4/5
around 22,000 ratings
Solid iOS scores. Most-praised: bill download, meter-read submission, in-app tariff switch, half-hourly smart-meter charts. Most-complained: occasional sign-in loops after major iOS updates and slow push notifications.
Channel
Google Play (YourEnergy app)
4.0/5
around 18,000 ratings
Lower than the iOS score, in line with the wider UK Big Six pattern. Recurring Android-specific complaints: notification reliability, occasional widget crashes, biometric login on older Android devices.
Channel
Reddit (r/UKPersonalFinance, r/UnitedKingdom)
Reddit threads skew critical: long-running threads about formal complaint delays and historical Ofgem fines (2015 / 2018) still surface in switching discussions. The Cap Tracker and EV Saver tariffs are recommended positively in EV-specific threads alongside Octopus Intelligent Go.
Channel
Ofgem regulatory record
Historical record includes the 2015 £18 million customer-service fine (the largest of its kind at the time) and a 2018 follow-up investigation. No major new enforcement cases in 2026. Compliance with the Standards of Conduct and the Energy Price Cap is currently in line with the wider Big Six.
Channel
Press coverage (BBC, Guardian, This is Money)
Press coverage concentrates on the Iberdrola £30bn UK investment plan, the East Anglia THREE offshore wind farm coming on stream during 2026, and quarterly cap-related price changes. The "100% renewable since 2018" claim is well documented in factual reporting.
Selectra expert verdict
Reading every channel together
Triangulating across Trustpilot, Google, the Citizens Advice supplier-performance table, the Which? annual survey, both app stores, Reddit and the Ofgem record, Scottish Power's online presence is genuinely two-speed. The brand is competitive-to-strong on call wait times, green credentials, the Cap Tracker tariff and the YourEnergy app; it is genuinely weak on formal complaint handling and on smart-meter operational issues, and it carries a long historical tail from the 2015 / 2018 Ofgem cases.
If you read only one signal, read the Citizens Advice supplier performance table: it is the only score built from regulator-supplied complaint and switching data rather than self-reported reviews, and it tracks the operational performance of Scottish Power in something close to real time. Cross-reference the headline ranking against the underlying sub-scores — Scottish Power's overall Citizens Advice rank flatters its weak complaints sub-score.
Reviews don't pay the bill — the tariff does.

Common questions
Scottish Power reviews — frequently asked questions
Scottish Power is regulated by Ofgem and bound by the Standards of Conduct that protect domestic customers. Reliability is best judged against your own usage profile: read recent reviews, check the Citizens Advice star rating for Scottish Power, and confirm the supplier's customer-service hours match when you actually need to call.
Trustpilot, Google Maps and app-store reviews reflect real experiences but are often skewed toward dissatisfied customers (people only post when something goes wrong). The most balanced single rating is Citizens Advice's quarterly supplier performance table, which scores all UK domestic suppliers on complaint handling, transfers, debt and communication — and is built from regulator-supplied data, not self-reported.
Confirm the unit rate (p/kWh) for both gas and electricity, the daily standing charge, the contract length, any exit fee (typical range: £25-£75 per fuel), and whether the deal requires a smart meter. Always cross-check the headline price against several other suppliers based on your actual postcode and annual kWh consumption from a recent bill.
If you're a current or former Scottish Power customer, share your experience on Trustpilot UK (search the supplier name), Google Maps (write a review on the Scottish Power business profile), or the Apple App Store and Google Play if you've used the mobile app. Selectra also collects independent reviews to help future customers compare suppliers objectively.
