Update on our tariffs

Frequently Asked Questions

Which fixed tariffs are available now?

So Spruce is our 24-month fixed tariff. Existing So Energy customers can find their rates in their renewal page in account. New customers can get a quote here.

What other tariffs are available with So Energy?

Our standard variable tariff, So Flex, and So Green Tracker are still available. Find out more.

Which is the best value tariff to switch to now?

So Green Tracker is currently the best value tariff for our customers, as it stays £50 below the price cap (£25 per fuel, based on typical domestic consumption values).

The price cap is due to fall in April, so the tracker will fall too. The July price cap is likely to rise, depending on the how long disruption continues – but So Green Tracker will still be £50 lower. This is the case as of 5 March 2026, but it’s worth checking back if disruption continues.

Should I fix my rates now?

At the moment it would be better value to switch to So Green Tracker as it remains below the price cap by £50 (£25 per fuel, based on typical domestic consumption values).

The price cap is due to fall in April, so the tracker will fall too. The July price cap is likely to rise, depending on the how long disruption continues – but So Green Tracker will remain below the price cap. Switching to a fixed rate is more expensive that the price cap currently. This is the case as of 5 March 2026, but it’s worth checking back as things change.

Will I still get the energy rate reductions in April?

All our customers will still benefit from the rate reductions from 1 April 2026, following action taken by the government. See April price reductions for more details.

When will I hear about what the April price cap means for me?

For existing customers on a variable rate tariff like So Flex, we’ll let you know by email or letter before 1 April 2026.

Will the increase in global oil and gas prices mean the April price cap will change?

No, the April price cap will remain the same. It’s possible the July price cap will increase, but by how much depends on how long wholesale market disruption continues.

Will my Direct Debit change?

We regularly check your Direct Debit to make sure you’re paying the right amount for your home. This is based on your tariff, where you live, and how much energy you use. If your account balance is in debit or credit, we may adjust your payments to help keep everything on track. When it’s time for a review, we’ll be in touch to talk you through your options.

I want to switch to an EV tariff, how do I do this?

We’re not offering our So EV tariff to new customers at the moment, while we review the global situation. We’ll update the website when this changes. Existing So EV customers aren’t affected, your rates remain the same.

What are the global events affecting energy prices?

A huge amount of the world’s oil travels through key routes in the Middle East, like the Strait of Hormuz, so any disruption pushes energy prices up. The ongoing political situation has caused gas and oil prices to rise sharply, because energy traders are preparing for possible supply shortages. When wholesale energy costs increase, suppliers need to raise fixed-price tariffs to cover the higher costs when contracts are renewed or the price cap is adjusted.
