Scottish Power is one of the UK’s most established providers, having been formed in 1990 in preparation for the privatisation of the previously state-owned Scottish electricity industry. Now owned by Spanish energy giant Iberdrola, it continues to supply around five million customers in the UK. Can the energy giant continue to hold its own in a market with an increasing number of independent providers offering affordable green alternatives?

Scottish Power reviews

An important consideration when deciding whether to join up with a provider is what its customers think of it. Scottish Power reviews aren’t positive. In fact, Scottish Power is one of the worst-reviewed providers on the market.

A score of 1.1 out of 5 stars gives a distinctly poor impression of its customer service and overall customer satisfaction. Complaints handling and rising costs seem to be the main reason that 96% of nearly 6,000 reviewers gave it the worst score of 1 star. Here’s what one customer had to say about its complaints process:

After leaving a complaint on Trustpilot and receiving a reply from Sam asking me to resend all the details over a week ago, I have heard nothing. My complaint has been going on for over 6 months.

No one likes to be put into a situation where they have to complain about their provider, but it can happen regardless of the company you’re with. What’s discouraging is that Scottish Power reviews suggest that the company has no interest in helping customers resolve their complaints or any issues they’re having.

Apart from poor customer service, there doesn’t seem to be much financial incentive for signing up to Scottish Power. Rising monthly payments and astronomical miscalculations that are too much for customers to afford is another common issue we see reported, with this customer representative of many more that have felt the pinch:

Receive an email to say I have an outstanding £919 to pay as they have undercharged me for the last 1 year. (...) Didn’t want to drag this on so I paid to get them off my back. Received my bill for this quarter but surprise surprise receive another email 2 days later to say I have a bill to pay. Absolutely ridiculous.

It goes without saying that Scottish Power reviews offer little reason for signing up with the provider, with reviews like the above ones predominating. Only 2% of customers find something positive to say about the provider, so it seems a risk to take the chance that you may be among the one in fifty reviewers who were happy with the provider.

Scottish Power tariffs

There are a number of Scottish Power tariffs available to those interested in signing up, but a good indication of how fair a provider is with its pricing is in its standard variable tariff, as it is what you’ll end up on when your initial contract runs out anyway.

The cheapest quotes we found for Scottish Power compare reasonably well to the market in general. The cheapest of the three, Greener Future, is around fifty pounds a year cheaper Ofgem’s price cap of £1,138 for dual fuel.

Scottish Power's standard variable tariffs do come in above the price cap, which makes us disinclined to recommend one of these. It’s important to note also that variable tariffs are subject to price hikes, which has been a common complaint about Scottish Power tariffs, as well as usage miscalculations and overcharging. A bit of shopping around could save you a lot!

Green tariffs

Unfortunately, Scottish Power tariffs are not entirely green according to our definition. This is because the fuel mix it uses to source its energy is not green, but it generates green energy to use for other products or sell into the national grid for every kilowatt it provides to domestic users. This ‘matching’ of energy is known as carbon offsetting, and environmentalists are divided on its merits - as are we, though it’s certainly better than doing nothing at all.

Scottish Power says that it matches 100% of the electricity its customers use with renewable energy generated at its plants, but its fuel mix (seen below) is what it is - still burning the earth’s non-renewable resources and contributing significantly to climate change.

There are 100% green Scottish Power tariffs available to small business customers, however, not much information on the tariffs themselves is available on the Scottish Power website. They do guarantee that REGO certificates will be provided with these tariffs - these certificates constitute proof that the energy is sourced from 100% renewable energy.

Fuel mix

Like all other UK providers, Scottish Power is obliged to report from where it sources its fuel from. You can see how it compares to the national average below:

- Coal Natural gas Nuclear Renewables Other
Scottish Power 5% 52% 11% 30% 2%
National average 3.9% 39.4% 16.6% 37.9% 2.2%

As you can see, the main difference between Scottish Power and the average supplier is that it sources around 10% more from natural gas than the average. Natural gas is a fossil fuel and though it does rely less on nuclear energy (which comes with its own problems) than other providers, we can’t say we approve of the trade-off.
