Company Overview
Octopus Energy
Founded in 2015, Octopus has grown into one of the UK’s biggest and best-known energy suppliers, recently overtaking British Gas in customer numbers. It’s recognised for transparent pricing, innovative tariffs and renewable electricity. The company has built a reputation for excellent customer service, strong digital tools, and a commitment to green energy.
Fuse Energy
Fuse is a newer entrant, but it’s been gaining attention fast. Its mission is simple: low prices, straightforward tariffs and a no-nonsense online experience. Many early customers say they were drawn in by the promise of cheaper bills and a refreshingly simple sign-up process.
Pricing and Tariffs
Fuse Energy
Fuse usually positions itself as a budget-friendly supplier, with slightly lower unit rates than most larger companies. Its pricing is lean, avoiding extras or complex tariffs. Most customers get a single straightforward plan, which keeps things simple if your main concern is cost.
Octopus Energy
Octopus’ prices vary by tariff type. Its Flexible and Fixed tariffs tend to hover around the Ofgem price-cap level, while its smart tariffs (Agile, Tracker, Intelligent Go) can save you money if you have a smart meter or electric vehicle. Octopus isn’t always the absolute cheapest on headline price, but it rewards tech-savvy and greener households with potentially significant savings.
Customer Service and Experience
Octopus Energy consistently ranks near the top of industry surveys for customer satisfaction. Users praise its friendly support team, fast response times, and intuitive app that makes tracking usage easy. However, its sheer size means a few customers report slower resolution times during busy periods.
Fuse Energy, being newer and smaller, feels more “hands-on” to many customers. Reviews highlight quick chat responses and a smooth digital sign-up experience. That said, because Fuse is still scaling, it doesn’t yet have the same depth of resources or long-term reputation that Octopus has built over nearly a decade.
Green Credentials
Octopus Energy supplies 100 % renewable electricity, backed by its own solar and wind projects across the UK. It also runs schemes to help customers shift energy usage away from peak hours, reducing grid strain and emissions.
Fuse Energy also provides green electricity, but it currently buys most of its renewable power on the open market rather than generating it directly. It’s still committed to sustainability but operates on a smaller scale.

Verdict: Which Is Best in 2025?
Both companies have their strengths — but they serve slightly different audiences.
Fuse Energy is best for budget-conscious customers who want low rates and a straightforward, digital-first experience. It’s ideal if you’re confident managing your energy online and your main goal is saving money.
Octopus Energy, on the other hand, remains the stronger overall choice for most households. Its combination of competitive pricing, innovative technology, top-tier customer service, and a proven green commitment make it the better all-round supplier in 2025. While Fuse Energy may edge it on raw cost for some, Octopus offers far greater flexibility, stability, and long-term trust — qualities that matter when it comes to your home energy.
Winner: Octopus Energy — for reliability, innovation, and customer satisfaction.
