About Jellyfish Energy
Jellyfish Energy is an independent UK energy supplier that has been providing gas and electricity to businesses and domestic customers since 2014. Based in Newcastle upon Tyne, they've positioned themselves as a tech-led supplier focused on transparency and flexibility.
The company's unusual name reflects their core philosophy — just as jellyfish are translucent, they aim to be transparent in their pricing and operations. Their digital-first approach includes a customer app that provides real-time bill breakdowns and meter reading reminders.
"We want to be known as more than just your energy supplier. We want to be a company you can trust and rely on."
One of Jellyfish's more distinctive features is their "Rating Algorithm" — a loyalty programme that rewards customers who pay on time and engage regularly. As you build your rating from Bronze through to Platinum, you unlock access to better rates and exclusive products.
They serve businesses across all sectors and sizes, from microbusinesses and SMEs to larger commercial operations with multiple sites. Their product range is notably flexible, with tariffs designed for different credit profiles and usage patterns.
