Fuse Energy: Compare Business Energy Deals Online

Launched in 2023 by former executives of the banking app Revolut, Fuse Energy is the newest challenger brand in the UK commercial market. Fuse has moved beyond its origins as an app-only residential supplier to become a major force in the SME sector. Their model is built on high-speed technology, lower overheads, and a unique Direct-to-Grid investment strategy that funnels profits directly into building new UK solar and wind farms.

For businesses that value a digital-first experience and want a supplier that prioritises reinvestment over corporate dividends, Fuse offers one of the most modern energy experiences in Britain.

Why Choose Fuse for Your Business Energy?

Fuse treats business energy like a software product, focusing on efficiency, data transparency, and price disruption.

• Reinvestment Model: Fuse owns and operates its own renewable assets (currently 18MW with more in development). Instead of just buying green certificates (REGOs), they reinvest 100% of their profits into building more UK-based clean energy infrastructure

• Always Beating the Cap: For variable-rate business customers, Fuse has a standing promise to stay cheaper than the major legacy suppliers by operating with significantly lower overheads

• Real-Time Data: Their app and online portal provide usage updates every 30 minutes. This level of granularity is essential for businesses preparing for the mandatory Market-wide Half-Hourly Settlement (MHHS) in 2026

• Fast Onboarding: Utilising bill-upload technology and AI-driven energy supplier switching, a business can move to Fuse in under 3 minutes—a fraction of the time taken by traditional providers

Business Energy Tariffs Breakdown

Fuse offers a streamlined selection of tariffs designed for the mobile-savvy business owner.

1. Small Business and SME Tariffs

• Fuse Fixed: Protect your business from market volatility with 12 or 24-month fixed-rate deals. These are often cited as some of the most competitive in the UK for micro-businesses

• Fuse Variable: A flexible, no-contract option. Fuse monitors wholesale prices daily to ensure their variable rates remain below the industry averages of the Big Six

• EV & Multi-Rate Tariffs: Specialised Time-of-Use tariffs for businesses with electric vehicles or those that can shift their heavy machinery usage to off-peak night hours (typically 12 am – 6 am)

2. Large Business and Industrial

For larger sites, Fuse provides Smart-Settlement contracts. These are designed for firms with SMETS2 or Half-Hourly meters, providing pricing that reflects actual consumption patterns rather than averaged profiles.

Sustainable Energy Services

Fuse has positioned itself as the Anti-Greenwash supplier, focusing on real-world impact:

• Transparent Fuel Mix: Fuse is one of the few suppliers to admit that 100% renewable supply 24/7 is not yet possible from the grid alone. Instead of buying paper certificates to hide this, they provide a live Transparency Report showing exactly how much carbon was emitted for every kWh you used

• Smart Meter Fast-Track: Fuse is a leader in rapid smart meter deployments. They averaged less than 5 working days from request to installation for SME customers

• Solar & Battery Integration: Through their partner network, Fuse helps businesses install on-site solar and battery storage, allowing them to sell excess power back to the grid via the Fuse app

Existing Fuse Customers: How Our Advisers Can Help

If your business is already with Fuse Energy, Money Helpdesk can help you leverage their tech-heavy platform for maximum savings. Our advisers offer:

• App-Data Auditing: We can provide a full businee energy audit of the 30-minute usage data in your Fuse app to identify equipment that is left on overnight or during weekends

• TNUoS Management: With the Transmission Network Use of System (TNUoS) cost increase in April 2026, we help you understand how these grid fees are applied to your Fuse standing charges

• Smart Meter Troubleshooting: If your Fuse smart meter goes offline or stops sending readings, our team can liaise with Fuse engineers to restore the data flow quickly

• Retention Benchmarking: We ensure that when your Fuse fixed deal ends, your new offer remains the cheapest in the market, or we help you switch to a newer challenger if one emerges

Pros and Cons of Fuse Business Energy

The Pros

• Cheapest Variable Rates: Consistently undercuts the major legacy suppliers on flexible pricing

• Exceptional App Experience: The most intuitive digital interface in the industry, making bill management as easy as mobile banking

• Rapid Customer Support: High Trustpilot ratings (4.7/5) with frequent praise for their almost immediate response times via app-chat

The Cons

• Digital-First Focus: While they have human support, the experience is heavily optimised for app and web users. If you prefer paper bills and traditional postal communication, Fuse may not be the right fit

• Young Company: Launched in 2023, they have less legacy stability than a firm like Centrica or EDF, though they are heavily backed by venture capital

• Limited Phone Hours: Support is highly responsive digitally, but phone-based customer service hours can be more restricted than larger utilities

Customer Consensus: What Businesses Say

The consensus is that Fuse is a breath of fresh air for small business owners who are tired of the slow, bureaucratic nature of traditional energy firms.

• The Positive: Customers rave about the Rob and Sasaki effect, referring to the real humans who jump into the chat to solve issues instantly. The 3-minute signup is a frequently cited pro that actually lives up to the marketing

• The Negative: Some users have reported initial confusion regarding how price changes are communicated through the app versus email, and others have noted that the Transparency Report can be complex for those just looking for a simple 100% Green label

The Procurement Process: Moving to Fuse

1. Bill Upload: Simply take a photo of your current business bill and send it to us or upload it to the Fuse website or app

2. AI Quote: Fuse’s AI analyses your usage and MPAN instantly to provide a fixed or variable quote

3. Digital Switch: Click to confirm. Fuse notifies your old supplier and handles the entire legal handover

4. Smart Installation: If you don't have one, Fuse will schedule a smart meter installation (often within 5 days) to ensure your account is fully digital from month one
