Green Star Energy customers to be bought by Shell Energy

What this means for 200,000 gas and electricity customers

Customers of Green Star Energy are set to move to Shell Energy, bringing the challenger brand to nearly one million customers.

The deal, announced yesterday, is for Shell Energy Retail to buy Green Star Energy’s parent company, Hudson Energy Supply. It is expected to be completed by the end of the year, as long as the merger is approved.

Shell Energy is already one of the biggest brands outside of the Big Six, with around 780,000 customers.

This is far from the first merger between challenger brands: Octopus begun supplying Co-operative Energy customers in July, while SSE is selling its household energy business to Ovo.

Read on to find out what this means for Green Star Energy customers and what Shell Energy’s customers think of it. Or compare gas and electricity prices using Which? Switch to check you’re on the best deal for you.

Green Star Energy customers: what this means for you

If you’re a Green Star Energy customer, you will continue to be supplied by Green Star until the deal completes. This is expected to be by the end of the year.

The terms and conditions of your tariff won’t change even when the deal is complete, both Green Star Energy and Shell Energy have said.

You will also still get Perks Rewards – points awarded every three months for customers on eligible tariffs which can be exchanged for gift cards and smart energy efficiency products.

Which is cheaper for gas and electricity?

At the moment, Shell Energy is selling the cheaper energy deal of the two companies. It costs £1,059 per year for a household using a medium amount of energy. Green Star’s cheapest deal costs around £91 more per year.

If you didn’t pick a new tariff when your last fixed deal ended, you’ll be on your supplier’s standard or default tariff. The firms are charging the same for these: £1,178 per year. There is currently a price cap on these types of tariffs and both are charging within £1 of the maximum permitted.

How much you’re paying depends on the tariff you are on, and how much gas and electricity you use.
