Scottish Power Business Energy Profile: Tariffs & Reviews

The company was founded in 1990 and is a subsidiary of Iberdrola, a Spanish utility company. Not only do Scottish Power supply energy, they also generate their own electricity, generating 100% of their electricity from wind farms.

  • Small, medium and large business tariffs 
  • Contract lengths from 1, 2 or 3 years

Scottish Power Fuel Mix 

As of 2020, Scottish Power is offering tariffs where 100% of the electricity comes from wind power, and they generate this electricity themselves rather than relying on energy certificates to offset their emissions. This makes them a green choice.  

For 2018-2019, their fuel mix was as follows: 

  • Coal – 5%
  • Gas – 52%
  • Nuclear – 11%
  • Renewable sources – 30%
  • Other Fuels – 2%


And their environmental impact was as follows:

  • CO2 emissions – 251g per kWh
  • Radioactive waste – 0.0008g per kWh


Note, however, that they also offer tariffs where they generate 100% of their electricity from wind. Not all their business energy products offer this, so it’s important you choose a green energy plan if that’s important to you.

Scottish Power Reviews

Scottish Power is rated poor among customer reviews online. 

Here’s a breakdown of their ratings across different review platforms:

  • Trustpilot – they have a 1.1/5 star rating based on over 5,000 reviews
  • Review Centre – they have a 1.2/5 star rating based on over 400 reviews 

Scottish Power has also been compared to other suppliers for complaints handling:

  • Citizens Advice – Scottish Power was ranked 11th in a table of 16 ranking non-domestic energy suppliers for complaints handling. 

How these ratings compare 

In terms of reviews published online, Scottish Power isn’t the best-reviewed supplier, but they aren’t the worst in the energy market either.  

If we combine the review rating systems of Trustpilot and Review Centre, they achieve a 2.3 out of 10 rating among customers overall. 

However, it’s important to bear in mind that unhappy customers are more inclined to leave a review than happy customers. 

In terms of complaints handling, the Citizens Advice data reveals Scottish Power handles complaints better than Gazprom, Npower, Utilita and Corona, but not as well as British Gas, SSE, EDF or Opus Energy. E.ON is ranked as the best.
