Scottish Power Review Summary
Scottish Power: At a Glance
Scottish Power is one of the UK’s largest energy suppliers and a major owner of UK wind farms.
It offers customers a choice of ‘green tariffs’ backed by 100% renewable electricity, although its standard fuel mix is primarily based on fossil fuels.
Its customer service record is mixed; it ranks well in the Citizens Advice star rating and on Trustpilot.
However, the latest Which? energy survey places it in the bottom third of the table, suggesting official performance metrics don’t always align with customer experience.
Who are ScottishPower?
Part of the Spanish Iberdrola Group, Scottish Power is a major UK energy company with roots in Glasgow, Scotland.
They are one of the ‘Big Six’ suppliers, providing gas and electricity to around five million homes and businesses.
A key part of their identity is a strong focus on wind power; they are one of the UK’s largest generators of wind energy and were the first major supplier to generate 100% of their electricity for green tariffs from their own wind farms.
What tariffs do ScottishPower offer?
Scottish Power provides a range of tariffs to suit different needs, including fixed-rate, variable-rate, and specialised tariffs.
Electric Vehicle (EV) Tariffs: They offer specialised tariffs for electric vehicle owners, providing cheaper off-peak electricity rates to make charging at home more affordable.
Fixed-Rate Tariffs: These lock in your unit rates for a set period, protecting you from price increases but often coming with an exit fee if you leave early. This includes their ‘Green’ tariffs, backed by 100% renewable electricity from their own wind farms.
Standard Variable Tariff (SVT): This is their default tariff with no exit fees. The price you pay is based on their standard fuel mix and can go up or down in line with the Ofgem energy price cap.
How does ScottishPower compare on price?

What do other ScottishPower reviews say?
Scottish Power’s customer review scores show a significant divide between different rating platforms.
On Trustpilot, Scottish Power has an Excellent rating of 4.3 out of 5 stars from over 124,000 reviews. Positive reviews frequently praise the user-friendly app and efficient customer service.
The most recent Citizens Advice star rating (January to March 2025) is also strong, placing Scottish Power 5th out of 15 suppliers with an overall score of 3.6 out of 5 stars.
It scores poorly for receiving complaints (2 out of 5 stars), with 47.6 complaints per 10,000 customers, but highly for contact waiting time and customer commitments.
In sharp contrast, the latest Which? energy survey ranked Scottish Power 13th out of 17 suppliers with a total score of just 59%. Its customer score within that survey was a below-average 58%.
How green is ScottishPower’s energy?
This is an area that requires careful attention.
According to official data from Citizens Advice, Scottish Power’s standard fuel mix for all customers is:
- Fossil Fuel: 73%
- Renewable: 11%
- Nuclear: 9%
- Other: 7%
However, Scottish Power heavily promotes its green credentials because it is a major generator of wind power. When you sign up for one of their specific ‘Green Tariffs’, they guarantee that 100% of the electricity you use is matched with power generated from their own UK wind farms.
So, while the company as a whole uses a mix with high fossil fuel content, it gives customers the option to have their usage backed entirely by certified renewable sources.
What is ScottishPower’s customer service like?
Getting in touch with Scottish Power is possible through several channels, with different opening hours depending on your customer type.
- Pay Monthly customers: Phone lines are open Monday to Friday, 9 am to 5 pm.
- Prepayment customers: Phone lines are open longer, from 9 am to 8 pm Monday to Friday, and 9 am to 4 pm on Saturdays.
According to the latest Citizens Advice data, the average call wait time is a very reasonable 1 minute and 27 seconds. The same data shows that 96.5% of customer emails are responded to within two working days.
A Live Chat service is also available on their website for all customers.
What is ScottishPower’s website/app like?
Scottish Power’s website contains a wealth of information, though it can sometimes be difficult to navigate to find specific details. It includes an online account management portal where customers can view bills, make payments, and submit meter readings.
The real standout is the Scottish Power mobile app, which is very highly rated by users.
The app allows you to manage your entire account, including topping up a smart prepayment meter and monitoring your energy usage.
It currently holds an excellent rating of 4.8 out of 5 stars on the Apple App Store and an equally impressive 4.8 out of 5 stars on the Google Play Store.
What billing options are available?
Scottish Power offers a flexible range of payment methods.
The most common method is monthly Direct Debit, which usually offers the cheapest unit rates. Customers can also pay by cash, cheque, or card at a bank, Post Office, or PayPoint retailer.
Payments can also be made online through the website or app, or over the phone.
For prepayment customers, top-ups can be made at any PayPoint retailer or, if you have a smart meter, online or through the mobile app.
Does ScottishPower offer a recommend a friend referral scheme?
Yes, Scottish Power runs a ‘Refer a Friend’ scheme.
When an existing customer refers a friend who then switches to Scottish Power, both parties can receive credit on their energy account. The current offer provides up to £60 credit each if the new customer signs up for both gas and electricity.
Who is Scottish Power good for?
- Customers who want a specific green tariff backed by a supplier that generates its own 100% renewable electricity in the UK.
- People who are comfortable managing their account digitally via the highly-rated mobile app.
- Prepayment customers who would benefit from longer customer service opening hours, including on Saturdays.
Who might Scottish Power not suit?
- Customers whose primary concern is consistently excellent customer service, given the poor result in the latest Which? survey.
- Anyone who wants their supplier’s standard energy mix to be 100% renewable.

Our Verdict
Scottish Power is a company of two halves. On one side, it’s a forward-thinking generator of renewable energy with one of the best mobile apps on the market, making digital account management a breeze.
On the other hand, its standard energy is far from green, and its customer service record is deeply inconsistent, scoring well on official metrics like call waiting times but failing to impress customers in the comprehensive Which? survey.
It’s a solid choice for digitally savvy customers who want to choose a green tariff from a major UK generator actively. Still, those seeking consistently top-tier service might be better served elsewhere.

Scottish Power are open on Saturdays from 8.30am to 13.30
Just billed £700 with no warning or change in usage. I was on hold for 3 hours then hung up on, they don’t respond to messages or in the chat. Merry Christmas I suppose
very very bad worst company I have ever used
do not ever use this supply
they are really bad at dealing with phone calls
line keep cutting off
very very bad service
Please don’t touch these bullies with a bargepole. Indo not wish harm on anyo but if any company deserves to go bust it’s them. I feel sorry for the decent people that work for them. Too much wrong with them to mention but I’ve had numerous ‘reminders’ sent out up to almost two weeks before bill is due . They threaten to send someone out to collect payment and say they can charge over twenty seven pounds for doing this and can enforce prepayment meters. They constantly increase the amount they say you owe. Truly scandalous. If you don’t have mental health issues before you join them you will have by the time you finish with them. I’ve kept letters etc and will be contacting newspapers
The Scottish Power smart meters triggers the RCD to switch off, leaving us without electricity in the following scenarios:
– every morning between 4-4:30 AM (as seen in this video; the beeping sound is from my UPS that alarm)
– every time we top-up
– randomly, sometimes multiple times per day in very short periods of time
..videos here https://www.youtube.com/playlist?list=PL9fYRyMJLvsKD-XwZv1vpfqK5sSS5gXly
For some reason, Scottish Power refuses to acknowledge this fact and to replace our smart meters back.
There is nothing wrong with our home network or the appliances, as this happens even if we turn off all the consumers. Besides, we have never had any issue with the old analogue meters.
We’ve reported this to SP and begged them to take their smart meters back. Almost three months have passed now – they still didn’t do anything yet. They simply do not care about about their customers, the appliances that get damaged due to this power cuts and most important the stress and health issues that this and the lack of sleep is causing us and our kids.
PLEASE DO NOT USE SCOTTISH POWER!
(The short version)
They promised me a fixed tariff of £45 a month and over a nine month period I was promised this would be honoured but never resolved after multiple phone calls to them and as the tariff came to an end they changed there mind and landed me with a big bill.
I’m going through the ombudsman and asked for recording of the conversation I signed up to and low and behold I got every other recording but this one !!
Iv tried setting up two direct debits to start paying off what I’m using currently while I sort out this and it’s like they don’t want to take my money as they take my details but never take any money out.
THIS IS BY FAR THE WORST ENERGY COMPANY IV EVER USED .
PLEASE READ THE REVIEWS ON GOOGLE BEFORE YOU EVEN CONSIDER SIGNING UP TO SCOTTISH POWER.
I can only assume it is for political reasons that Scottish Power could every score as high as 7.9, as no one with any real world experience of the cripplingly bureaucratic mess of miscommunication will know that they should be getting 0s across the board on Reviews, Customer Service, and Pricing, and I’m sure other categories too, though I haven’t had the displeasure of deep diving elsewhere.
I have been with Scottish Power a total of two times in my life. Both times I switched pretty sharpish. The first time I tried to switch as their prices were around 25% higher than competitors with better green credentials (I switched to Bulb in 2015 for reference). This proved to be a multi-month process in which my switch was blocked by SP repeatedly due to an unpaid bill (totalling around £6 over the course of the 2 or 3 weeks since I last paid a bill), during which time I had to explain the exact issue to around 4 representatives, none of whom seemed to grasp the issue, and I was forced to endure their train-wreck customer service for multiple hours in total over a period of around 3 weeks.
Naturally, when I was automatically moved to them when Yorkshire Energy went bust, I resolved to leave immediately. This was in March. I am still dealing with them at the end of June. This time I did not even bother to see if they were cheaper or not, but based on the fact that I was previously paying £75 a month to YE and built up a credit of £170 over 6 months, and that they are now (if they finally have their calculations correct) charging me £370 for a 3 month period, meaning a cost to me of around £125 a month, I suspect their prices are not competitive. (I am now with Octopus, with whom I am also paying around £75 a month.)
This alone is reason enough to doubt the 7.9 score here, but if you will indulge me, this tale really shows what a 7.2/10 customer service really represents.
After resolving to switch immediately, I started the process of switching to Octopus Energy, only to find out, one month later, that Octopus were unable to make the switch as in had been less than 35 days since I last switched provider. I did not choose to switch provider, so this seems a strained point already, but I humoured the system and waited. I started the switch process again when I could and eventually switched to Octopus three months after joining SP. At which point they sent me a final bill. This is where the fun begins.
I won’t go too in depth, but basically, I had 2 electricity meters. SP took both meters from YE when they took over, but only took one reading, which they applied to both meters. They then estimated all my bills over the next 3 months and when they handed control over to Octopus, they only relinquished one meter, and provided the incorrect opening meter readings.
Over the next three months, I have spoken to I believe 13 different members of the Scottish Power team, to try and correct this mistake, and send the second electricity meter to Octopus. The latter is achieved, Octopus handled that remarkably fast.
However after spending about 12+ hours on the phone to Scottish Power, to try and correct my meter readings, they succeeded in getting the values wrong 3 more times, most recently getting the right values but the wrong dates. I *think* they now have it correct, and are just woefully expensive, but I am waiting on them to send me full details of my meter readings (I cannot login to check as my account is deactivated since I left). I am not hopeful that they will follow up as requested and as promised however, as so far I have 4 different emails with promised to follow up, and no follow ups, as well as three separate people promising to be in touch over phone, that I never heard from again.
Not that I am saying Scottish Power are uncommunicative. No, they have sent me no fewer than 8 bills via both email and mail, with at least 6 different requested values. In addition I’ve received 2 threatening letters about non-payment. They even started phoning me daily! Not to deal with my issues of course, but to demand money. The worst was the person who demanded payment, and when I explained the situation, demanded partial payment. At which point I asked what I would be partially paying as the meter they were trying to charge me for had not been used at all since I switched to SP. Not one unit!
This is by no means a comprehensive breakdown of the shocking service provided to me, though I’m sure it feels like it at this point. And I do not want you thinking these are rare isolated incidents. My friend has a third, and equally torturous tale to back this up, happening simultaneously right now! But that is his story to tell.
In summary, and to voice the opinions of the many thousands who have probably been overcharged, bamboozled and extorted by Scottish Power, whether wilfully, or through sheer incompetence, let me say. DO NOT USE SCOTTISH POWER. Do not believe that a 7.9 is a reasonable score. The only reason these people are allowed to operate is presumably because they’re so big that they’re untouchable.
I am having the same trouble only it’s nearly 2 years and I have now a big bill which is not my fault
My agent applied for business gas. Because for 3 months no reply, I called SP. I have been told they can,t supply me because I have too high usage. Customer Service told me: SP have a cup for selling gas and this is 145000kwh per year. I am using around 165000kwh so…( I have been told) -SP reject my application. I had to look for another supplier, engaged a lot of my time and energy. I signed a contract with Avanti and suddenly I receive a letter from SP- that will switch my gas in a few days??? I called SP to stop this switch but Customer Service did nothing, refuse to connect me with a manager or other superior…just left me like that. Horrible experience!!! I reminded myself that long time ago I had a huge problem with Scottish Power ,and I promised myself never use their service again. I should keep my promise and save myself from disappointment.
I was forced to use Scottish Power following the failure of my previous supplier. It took me 3 months to disengage from their clutches. During that time I was unable to access my online account nor change supplier. I eventually left without seeing a final bill. After some difficulty this was was resolved. I find it easy to understand why Which? rate them 24th out of 25 for customer satisfaction. A company best avoided.
They have terrible customer service. I have been trying to sort out a new tariff which I applied for online. After trying to get this confirmed for nearly 2 months with customer service they eventually said they had no record of this , although they have acknowledged the boiler insurance which was included and debited. The new tariff I was offered is more expensive. I have been now waiting nearly a week to speak to the complaints department and am changing to a new supplier. I wish I had read the reviews before.
Scottish power are no where near 7.9!
They’re aTerrible company with no robust process in place to ensure their paying customers are cared for.
Never contactable, spent all day on hold, both on the phone, on chat and no response to emails.
They believe it to be acceptable to dump a last minute hugely incorrect bill on your doorstep of over £430 for one months gas and electric. On top of this the threat to send debt collection agencies to your address if you dont pay. When you, rightfully as a paying customer, want to view your bill to correct their mistake, you cannot view online as the system doesnt work, cannot view via their app as the system doesnt work, or contact anyone on their phone lines (who then play recorded messages, begging you to look online at your Bill’s, which of course you cant), so you try and raise a complaint, which goes nowhere.
Cannot understand how they operate as a registered business with this blatent disregard for their paying customers, never mind such a large ‘supposedly’ reputable business.
No valid responses or customer care means I happily raise to the financial ombudsman service, which I’m sure are harder to ignore than one of their paying customers.
Scottish power are taking over £110 a month for electric. It was £60 and that was alot already. As a one parent with a small two bed, Led light bulbs I advise you to stay away from them. I am leaving them today, after I changed the dd back to £60 but they went and took nearly double instead (again) and ignored the change. I explained to them previously the amount they take chops into my shopping money but they just take as they want. Never been charged so much for electric in my life, wish I never joined them. The year contract is up, I am happy to leave.
I was happy with my standard meter but they kept chasing me to switch to smart meter. And now I am having issues even to read manually since the screen for gas meter is off and even pressing buttons do not show any readings. On top of customer service is rude and do not understand why I am frustrated.
The company just keep charging using estimate reading and raising the direct debit.
So easy to put everything on COVID lockdown … pathetic.
I run my own business and still offering full service to customers.
I have over the past 3 years had to change energy companies which were forced to close down by the regulator because they had never sourced enough of their energy from green renewable places. I found both of the companies, Breeze & Yorkshire Energy to be excellent over the time that they have supplied my energy. When Y.E closed its customers were given over to Scottish Power and as I’m an elderly pensioner I have found the tariffs of S P to be a lot more expensive than some of the smaller energy companies. I am now considering Avro, but like my two previous energy companies they don’t seem to source a large number of green renewables eitWhat do you think?
