About Scottish Power

ScottishPower is part of the Iberdrola Group, one of the world’s largest integrated utility companies and a world leader in wind energy. ScottishPower is the first integrated energy company in the UK to generate 100% green electricity.

My Review 

I reviewed all of the Energy Suppliers in the UK that I know and Scottish Power ranked #1 on that list. My review was based upon four criteria; 

  • Cheap prices
  • Ethical Practices
  • Ease of Communication
  • Problem solving

Here’s my review of Scottish Power;

Cheap Prices

Scottish Power are consistently the cheapest supplier for so many of my quotes. Around 7 out of 10 quotes, they are in the top three prices for each meter.

Ethical Practices

Scottish Power are one of the only energy suppliers that I couldn’t criticise for their practices. They don’t automatically roll over customers, termination is accepted, transfers are not blocked without reason and they allow customers to pay via all payment methods. Probably the best ethical practise of Scottish Powers is that their energy is green, 100% renewable.

Ease of Contact

Scottish Power can be contacted easily by phone, email, social media and online chat. This might sound trivial but hardly any suppliers in the UK are this open for customers to communicate with. They respond via twitter and web chat literally within minutes.

Problem Solving

I deal with complaints weekly, due to their large customer base, many revolve around the Big 6. Scottish Power are among the best at dealing with complaints – resolving all of my complaints with them except one (sorry Perry). Their customer service agents are nice and all call centre agents I’ve dealt with are native English speakers. Scottish Power have made opening complaints super easy and emails are responded to very quickly from staff assuring you they have passed on your complaint to the relevant department.

Customers can nominate a calendar day for the Direct Debit to be taken each month.

Renewal Contracts will only start on the 1st of the month. 

Terminations & Renewals


Fixed Price Contracts – Contracts can be terminated at any time up to 30 days prior to its expiry. However, the contract must run its full term.

Standard Fixed Tariff – A minimum of 30 days’ notice of termination must be given as specified in the Terms and Conditions.

Renewal Cycle

Scottish Power will write to business customers at least 60 days before their contract ends, advising of the customer’s options including the charges for a new Fixed Price Period tariff.

If a business customer chooses not to opt into a new Fixed Price Period tariff Scottish Power will automatically move the business’ electricity account to their Standard Fixed tariff at the end of their current contract.

It’s my third month of taking Propecia. I can’t see much of a difference yet but my doctor says everything goes well. He says that changes will be noticeable by the end of the sixth month. I’m looking forward to that moment, and I promise to share my progress with you. As of now, I feel well, not a single side effect of the Propecia.

This will be more expensive than a new Fixed Price Period tariff however the business customer would be free to leave at any point following a 30-day written notice.  Scottish Power will also include information on how to terminate their supply if the customer wishes to switch to a different supplier:
