SSE Energy Services is one of what was known until recently as the ‘Big Six’ gas and electricity suppliers and has around eight million customers, while Shell Energy has “just shy of one million customers”.
SSE Energy Services was bought by OVO Energy in 2020 but operates as a separate supplier, while Shell Energy is the new name for Utility Warehouse after it was bought by Shell and rebranded in March 2019.
But how do they compare on the things that really matter? Let's find out.

As well as its standard variable tariff and its Fix and Drive electric vehicle tariff, SSE Energy Services offers these tariffs:
SSE Fix and Control v3
Fixed-price energy for two years, plus a Google Nest thermostat E (RRP £199) and a Nest Hub (second generation and RRP £89.99). You must have a smart meter installed and the exit fee is £75 per fuel.
SSE Fix and Protect v3 Bundle

Conclusion
SSE Energy Services had the cheapest deals on our search if you are also looking for a boiler maintenance or broadband deal – but check the small print carefully as exclusions and a hefty exit fee can apply to add-ons.
It languishes towards the bottom of Which?’s customer survey but scores well on Trustpilot. Meanwhile, Shell Energy came 17th in the Which? survey but had quite a few bad reviews on Trustpilot.
SSE Energy Services’ Go Green scheme for 100% renewable electricity costs an extra £36 a year, while Shell Energy’s are already renewable – so bear that in mind when comparing these suppliers’ tariffs and deciding which is best for you.
