Ovo to take on Spark Energy’s customers: what next?

Written by:
Ofgem has appointed Ovo Energy to take on Spark Energy’s 290,000 domestic customers after the supplier ceased trading last week.

Separately, Ovo Energy has acquired Spark Energy’s operating company Spark Energy Ltd and retained the Spark Energy brand.

Energy will be supplied under Ovo Energy’s supply licence.

As Ovo Energy has acquired the Spark brand and operating company, customers will continue to be billed by Spark and be contacted by Spark’s customer service staff.

Stephen Fitzpatrick, CEO and founder of OVO, said: “The energy sector is going through a major change and many companies, big and small, are struggling to adapt. We are are delighted to have been able to bring Spark into the OVO Energy Group, securing a good outcome for their customers and the team.

“We will combine OVO’s innovative technology and focus on customer experience with Spark’s unique network of partnerships to bring greater products and services to more households around the UK.”

Our Q&A explains what happens next:

What tariff will I be put on?

Spark Energy’s customers will stay on the same tariffs and all outstanding credit balances will be honoured, including money owed to both existing and former customers of Spark Energy.

Can I switch provider?

Yes, but Ofgem suggests sitting tight until you hear from your supplier.

Spark Energy’s customers will be supplied by Ovo Energy as of Wednesday 28 November.

Customers of Spark Energy will be contacted over the coming days about the changes. If you wish to change your tariff or switch supplier, you should ask to be switched to another Ovo Energy tariff, or shop around.

You won’t be charged any exit penalties.

What should I do about my direct debit?

If you pay by direct debit, you should not cancel your arrangement, but don’t panic if you already have. Spark Energy will contact you shortly to explain how they will set up your account.

I have more questions, who should I contact?
