Scottish Power Review: Is It a Good Energy Supplier in 2026?
Scottish Power is one of the major energy suppliers in the UK, supplying gas and electricity to millions of households across the country. It is part of Iberdrola, a large international energy group with significant operations in wind power and renewable energy generation. That ownership gives Scottish Power a different character to some of its competitors, with a stronger direct link to renewable electricity generation than many retail suppliers can claim.
The company has been part of the UK energy landscape for decades and competes directly with British Gas, Octopus Energy, OVO Energy, and other large suppliers for household customers. It offers a range of tariffs including fixed deals, variable rates, and green energy options.
Being a well-known name in the market does not automatically make it the best choice for every household, though. Pricing, customer service, and tariff availability all vary, and the energy market has changed considerably in recent years.
This review covers what you need to know before deciding whether to switch to Scottish Power. You will find a breakdown of tariffs and pricing, a summary of customer feedback, and a comparison with other suppliers.

Scottish Power: Company Background
Scottish Power has its roots in Scotland, where it was originally formed as a regional electricity company following the privatisation of the electricity industry in 1991. Over the following years it expanded its operations across the UK, growing from a regional supplier into one of the larger national energy companies.
In 2007, Scottish Power was acquired by Iberdrola, a Spanish multinational energy group with a major focus on renewable electricity generation. Iberdrola is one of the largest wind energy operators in the world, and that ownership has shaped Scottish Power’s direction. The company has invested heavily in wind power in the UK, particularly in Scotland and offshore wind projects around the British coastline.
This matters in practical terms for customers. Scottish Power can point to a genuine generation portfolio behind its renewable electricity claims, rather than relying solely on certificates bought on the open market. That is a meaningful distinction for households who care about where their electricity actually comes from.
In the retail market, Scottish Power supplies millions of homes with gas and electricity across Great Britain. It competes with British Gas, Octopus Energy, and OVO Energy for household customers and offers a range of tariffs suited to different budgets and priorities.
Like other large suppliers, Scottish Power has faced challenges in the retail market over the years, including periods of criticism around customer service and billing. It remains a significant player and continues to develop its tariff range alongside its renewable energy investments.
Scottish Power Tariffs Explained
Scottish Power offers several tariff types. Here is a breakdown of the main options and the households they tend to suit.
Fixed rate tariffs
Scottish Power’s fixed tariffs lock in your unit rate for a set period, usually 12 months. Your price will not change during the fixed term regardless of what happens to the Ofgem price cap or wholesale market conditions. This provides predictability over your bills and protects you if energy prices rise.
As with any fixed deal, there are trade-offs. If market prices fall during your fixed term, you will not benefit until it ends. Some fixed tariffs also carry early exit fees, so it is worth reading the terms before committing.
Standard variable tariff
Scottish Power’s standard variable tariff follows the Ofgem price cap and adjusts when the cap is reviewed each quarter. There are no exit fees, which keeps things flexible if you want to switch at short notice. The downside is that your bills can rise when the cap increases.
Customers who have been with Scottish Power for a long time without actively choosing a tariff are likely on the standard variable rate. It is usually worth comparing against available fixed deals to see whether switching tariff would reduce your bills.
Renewable electricity tariffs
Scottish Power offers tariffs backed by renewable electricity. Given Iberdrola’s wind energy operations, Scottish Power’s renewable credentials have a genuine generation component behind them. For households who want to support renewable electricity and prefer a supplier with a direct link to wind and other clean energy sources, this is worth considering.
EV tariffs
Scottish Power offers tariffs designed for electric vehicle owners, with lower overnight unit rates to reduce the cost of home charging. If you have an EV and a smart meter, this kind of tariff can make a noticeable difference to what you pay each month compared with a standard rate.
Tariff availability changes depending on your location and current market conditions. Comparing directly using your postcode and estimated usage is the most reliable way to see what Scottish Power is currently offering.
Scottish Power Prices and Standing Charges
Scottish Power pricing follows the same structure as other major UK suppliers. Variable tariff rates are governed by the Ofgem price cap, and fixed tariff rates are set when you sign up.
Unit rates
The unit rate is what you pay per kilowatt hour of gas or electricity used. Scottish Power unit rates vary by region, reflecting differences in local distribution costs across the country. This is consistent with how all suppliers price energy and is not unique to Scottish Power.
Standing charges
Standing charges are a fixed daily fee applied to both your gas and electricity accounts. They cover the cost of maintaining your connection to the energy network and apply regardless of how much energy you use on any given day. For households with lower energy consumption, standing charges can represent a significant slice of the overall bill.
How competitive are Scottish Power prices?
On standard fixed tariffs, Scottish Power prices sit broadly in line with other large suppliers. They tend to offer better value than staying on an unreviewed standard variable rate, but they do not always match the most competitive deals available from newer or smaller suppliers.
Prices change regularly and vary by region, so comparing directly using current tariff data is far more useful than any figure quoted in a review.

Scottish Power Customer Reviews
Scottish Power’s customer reviews are mixed, which is a pattern that runs across most of the larger legacy suppliers. On Trustpilot and other review platforms, it sits in similar territory to British Gas and OVO Energy, performing better than the worst-rated suppliers but well below Octopus Energy’s customer satisfaction scores.
Review patterns follow a familiar split. Customers who have had straightforward billing and no need to contact Scottish Power directly tend to report positive or neutral experiences. Those who have had to chase a billing issue, dispute a meter reading, or deal with an account problem report more frustrating experiences, particularly around response times.
Common positive feedback includes:
- Renewable energy credentials appreciated by environmentally conscious customers
- EV tariff users reporting overnight savings on vehicle charging
- Smart meter installation process described positively by many customers
- Online account management tools rated reasonably well
Common criticisms include:
- Customer service response times, particularly by phone during busy periods
- Billing errors and estimated reads causing frustration for some customers
- Complaints about direct debit adjustments not being communicated clearly
Scottish Power has faced formal scrutiny from Ofgem in the past over billing and customer service practices and has been required to improve in these areas. More recent data suggests some progress, but the overall picture from customer reviews remains patchy.
Reading recent reviews rather than relying on overall platform scores will give a more current and accurate sense of how Scottish Power is performing.
Is Scottish Power Good Value?
For many households, Scottish Power offers reasonable value on fixed tariffs, particularly when compared with staying on a default variable rate that has never been reviewed. The difference between an unreviewed variable tariff and a competitive fixed deal can be several hundred pounds per year depending on usage and location.
Against Octopus Energy, Scottish Power does not consistently come out ahead on price or customer service. Octopus frequently offers competitive fixed tariffs and has a stronger track record for customer satisfaction. For households where price and service quality are the main priorities, Octopus is usually worth including in any direct comparison.
Against British Gas, the comparison is closer. Both are large, established suppliers with broadly similar pricing structures on standard fixed deals. Scottish Power’s renewable energy credentials give it a point of difference for environmentally motivated customers, while British Gas has the edge in additional home services like boiler cover.
Against E.ON Next, prices are often similar on equivalent deals. The choice between the two may come down to which offers the sharper current tariff in your region, or which has the stronger recent customer service record at the time you are comparing.
Scottish Power’s wind energy background is a genuine differentiator for households who care about where their electricity comes from. Whether that is worth paying more than the cheapest available deal is a personal decision.

How to Switch to Scottish Power
Switching to Scottish Power follows the same straightforward process as switching to any UK energy supplier.
Step 1: Compare tariffs
Use an energy comparison tool to see what Scottish Power is currently offering alongside deals from other suppliers. You will need your postcode and an estimate of your annual energy usage in kWh, which you can find on a recent bill.
Step 2: Choose a tariff
Select the Scottish Power tariff that suits your household. If you have an electric vehicle, the EV tariff is worth a close look. If you want price certainty, a fixed rate tariff is usually the safer choice.
Step 3: Enter your details
Provide your personal information, current meter readings, and your preferred payment method. Monthly direct debit is the most common payment approach and is usually the cheapest way to pay.
Step 4: The switch completes
Switching typically takes around five working days. Your gas and electricity supply will not be interrupted at any point during the process. You will not notice any change in the energy coming into your home.
Step 5: Submit a meter reading
Once the switch is complete, provide an opening meter reading to Scottish Power. This ensures your first bill is accurate rather than estimated. If you have a compatible smart meter, readings may be submitted automatically.
Scottish Power vs Other Energy Suppliers
Scottish Power vs Octopus Energy
Octopus Energy consistently outperforms Scottish Power in customer satisfaction surveys and often offers competitive fixed tariffs. Octopus also has smart tariff options like Agile and Tracker that suit households with flexible energy habits and smart meters. On renewable energy, both suppliers have green credentials, though they come from different directions. Octopus backs its tariffs with renewable certificates, while Scottish Power has a direct link to wind generation through its Iberdrola ownership. For households who prioritise customer service and competitive pricing, Octopus is generally the stronger comparison.
Scottish Power vs British Gas
British Gas and Scottish Power are both large, established suppliers with broadly similar tariff pricing on standard fixed deals. British Gas has the edge on brand recognition and offers home services like boiler cover that Scottish Power does not bundle with energy supply. Scottish Power has the stronger renewable energy generation story through its Iberdrola connection. Customer service records for both suppliers are mixed, sitting in similar territory on satisfaction surveys. The choice between them often comes down to a direct price comparison at the time of switching.
Scottish Power vs OVO Energy
OVO Energy and Scottish Power both emphasise renewable electricity and sustainability. OVO’s approach is more focused on carbon offsets and clean energy initiatives, while Scottish Power’s credentials come from its wind generation portfolio. Customer service feedback for both suppliers is variable, with neither standing out significantly ahead of the other. Tariff prices are worth comparing directly since they shift regularly and vary by region.
Should You Switch to Scottish Power?
Scottish Power is a well-established supplier with a genuine renewable energy story behind it. Its connection to Iberdrola’s wind energy operations gives it a stronger green credentials than many suppliers who simply buy renewable certificates. It offers a reasonable range of tariffs including fixed deals, variable options, and EV-specific plans, and it covers the whole of Great Britain.
At the same time, customer service feedback has been inconsistent, and Scottish Power does not always offer the most competitive prices in a direct comparison. Octopus Energy in particular tends to outperform it on both satisfaction scores and tariff competitiveness, making it a worthwhile comparison before deciding.
If renewable energy credentials matter to you and you want a large, established supplier with a long track record, Scottish Power is worth including in your shortlist. The most important step, though, is to compare current tariffs before switching rather than choosing a supplier based on reputation alone.
