Scottish Power Review

Scottish Power is one of the Big Six energy suppliers in the UK. This company claims to be the first electric utility in the UK to deliver 100% renewable energy to its customers. The utility also has several projects in place to help the UK achieve its Net Zero target.

This utility has excellent tariffs and a wide variety of services that will make your life easier. In this article, we analyze in detail every aspect of this company, its tariff plans, pricing, and we even take into account the opinion of current customers regarding the performance of the company. 

Who is Scottish Power? 

Scottish Power is the first energy provider in the UK that delivers customers with the option of providing them with 100% green energy. Aside from delivering electric power to homes and businesses, this utility provides gas service and some other extra services.

While most utilities providing clean energy purchase a fraction of all of their renewable energy from generators across the UK, Scottish Power generates their green energy with a series of wind farms located in the region. These wind farms allow the company to include the green tariffs, so homeowners and businesses can consume 100% clean energy.

In total, Scottish Power has over 40 operational wind farms, achieving a total wind capacity of 2,000 MW. This company is a subsidiary of the Iberdrola Group, a world-leading energy provider that is leading the renewable energy industry with a total installed capacity of 29,500W.

Scottish Power operates in the central and southern region of Scotland, the northern region of Wales, in Merseyside, and a fraction of Cheshire and Shropshire. 

Is Scottish Power Going Bust?

Since the reopening of the economy in 2021 after the COVID-19 lockdown, the cost for liquefied natural gas hit a record high, due to Asia lowering the supply delivered to Europe, deeply affecting the energy industry.

By October 2021, around 13 British electrical suppliers went bust, forcing 2 million customers to switch providers. By December, this number increased to 30 companies in total, which arises the question of whether or not will Scottish Power go bust. Well, it seems not.

While the crisis will not go unnoticed for Scottish Power since its profits dropped by 39%, it is important to remember that this electric supplier is still one of the Big Six. Scottish Power has acquired the customer portfolio of several busted companies, increasing their customers by 70,400.

Scottish power also has two extra points in favor. First and foremost, at least 40% of the energy supplied by this company comes from renewable or clean sources, and secondly, Scottish Power is not alone. This company is owned by the Iberdrola Group, meaning that the parent company which is much larger, can provide slightly lower gas prices for its subsidiary in the UK.  

Considering both points in favor for Scottish Power, customers of this company should not worry about the company going bust, but they should concern about energy prices increasing, like they will do with every other company. Ofgem already increased the price cap by 12% in past months, and customers should expect a new increase by next April, increasing the annual bill cost up to £1,660 a year.

Scottish Power Market Share

Scottish Power, is considered to be one of the Big Six energy suppliers. This is a group that comprises the six biggest gas and electricity suppliers in the UK: British Gas, EDF, E.ON, RWE Npower, Scottish Power, and SSE/OVO Energy.

Customer Reviews

If you want to know the real performance of Scottish Power, the best way is to directly read the opinion of the current customers of the company. This company has been rated 1.1/5 on Trustpilot, and it is placed 24th out of 25 on the surveys performed by Which?.

According to most customers, this company has been poorly performing in the electrical industry of the UK. There are many reports regarding bill inaccuracy, a poor handle of customer complaints, and several other issues.

According to Which? Surveys, customers do not feel that they are getting the value for their money with Scottish Power. Due to these and several other reasons, the UK regulator Ofgem has taken compliance actions into Scottish Power, to help the electric utility solve these issues and target a better service to UK customers. 

How Green Is Scottish Power’s Energy

Scottish Power, states that they are a 100% clean energy electric utility, however, this is not entirely true. While this company does provide customers with the option to fully use renewable energy under the Green Tariffs plan, it also has clients that are subscribed to other tariffs.

In the Fuel Mix section of the Scottish Power website, you can learn about how green Scottish Power is. Here, you will learn that customers subscribed to ‚Äúother tariffs‚ÄĚ, consume energy from other sources that are not the 40 wind farms generating the renewable energy of the company. Customers under these tariffs will consume energy from the following sources:

  • 6% of the energy is generated from coal.
  • 71% of the energy is generated from gas.
  • 9% of the energy is generated from nuclear.
  • ¬†8% of the energy is generated from renewable sources.
  • 6% of the energy is generated from other sources.

After factoring in both, the customers under the Green Tariffs and the Other tariffs, the Fuel Mix of Scottish Power for the 2020 ‚Äď 2021 year is the following:

  • 4% of the energy is generated from coal.
  • 46% of the energy is generated from gas.
  • 6% of the energy is generated from nuclear plants.
  • 40% of the energy is generated from renewable sources.
  • ¬†4% of the energy is generated from other sources.

Considering these numbers, Scottish Power only operates with a 40% renewable energy source. This means that up to 60% of the energy operated by Scottish Power, does not come from renewable sources.

Verdict on Scottish Power

Scottish Power is one of the Big Six energy suppliers in the UK, but sadly, this does not make it one of the best ones. This company has a relatively bad reputation regarding customer support, bill clarity, and several other aspects.

This UK utility has many interesting tariffs for home business customers, making it a great option, price-wise. Since Ofgem stepped in, the company has apparently been improving, which is an interesting bright side for future clients.

If you are doubtful about switching to Scottish Power, we recommend you keep a close eye on its improvements over time. This company offers several interesting services, making it potentially good for the future, but at the current date, it might not be the best option for you.
