What Makes a Good Business Electricity Supplier?

Before comparing individual suppliers, it helps to know what separates a good business electricity supplier from a poor one. The best providers tend to share a few key qualities:

• Competitive, transparent pricing - clear unit rates and standing charges, with no hidden fees.

• Contract flexibility - a choice of fixed and flexible terms, and lengths that suit your business.

• Reliable customer service - responsive, ideally UK-based support and accurate, on-time billing.

• Easy account management - an online portal or app, and support for smart or half-hourly meters.

• Green options - 100% renewable electricity backed by REGO certificates, if sustainability matters to you.

• The right fit for your size - some suppliers specialise in SMEs, others in large industrial and commercial users.

• Fair renewal terms - no punitive out-of-contract or automatic-rollover rates, and reasonable exit fees.

• A solid reputation - strong independent reviews, such as Trustpilot and Which?, and a track record you can trust.

Cons: Business electricity is a newer addition (launched in 2024) with a shorter track record than its gas supply, and it is a smaller independent with a narrower range than the majors.

Crown Gas & Power, part of the Crown Oil group and based in Greater Manchester, has supplied business gas since 2001 and added business electricity in 2024. It serves SMEs and larger commercial customers with fixed-price and variable-length contracts, offering 100% renewable electricity backed by wind REGO certificates and green gas at biomethane blends from 10% to 100%.

Pros: Backed by German government ownership for strong counterparty security, an award-recognised UK customer-service team, a full range from fixed to flexible contracts for very large users.

Cons: Some lingering brand association from its former Gazprom Energy name, and its green-gas option leans partly on carbon offsets rather than physical biomethane.

Brook Green Supply

Trustpilot Rating: N/A

Pros: A specialist focus on larger industrial and commercial users, 100% renewable REGO-backed electricity, the flexibility of an independent to tailor contracts to individual large sites.

Cons: Not aimed at small or micro-businesses, and a minimal public review footprint (as is common for suppliers that serve only large users through brokers).

Brook Green Supply, established in 2015 and based in London, is a specialist supplier of gas and electricity to industrial and commercial (I&C) energy users rather than small businesses or households. It offers fixed-price, pass-through and flexible contracts, including 100% renewable electricity backed by REGO certificates, designed around larger and higher-consumption organisations.

It offers fixed-price tariffs of 12 to 36 months alongside flexible, pass-through and multi-site contracts.
