Who Are The Best Business Gas Suppliers?

If you’re running a business, choosing the right business gas supplier is one of the best ways to keep your overheads under control. Business gas is bought differently from domestic gas: contracts are fixed-term and bespoke, and you also pay the Climate Change Levy on top of your unit rate. Below are some of the most recommended business gas suppliers in the UK, from the major names to gas specialists and greener, biomethane-backed options. Looking for electricity too? See our guide to the best business electricity suppliers, or our overview of business energy suppliers.

A quick note: the Trustpilot ratings are correct as of August 2026.

What Makes a Good Business Gas Supplier?

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

• Competitive, transparent gas pricing - clear unit rates and standing charges, remembering that business gas also carries the Climate Change Levy.

• Contract flexibility - fixed and flexible gas terms, and gas-only or dual-fuel options to suit your setup.

• Green gas options - certified biomethane (backed by Renewable Gas Guarantees of Origin) or a carbon-neutral gas product, if sustainability matters to you.

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

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

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

• Fair renewal terms - no punitive out-of-contract or automatic-rollover rates.

• A solid reputation - strong independent reviews and a track record you can trust.

Suppliers

British Gas

Trustpilot Rating: 4.4

Pros: major established brand, a 100% biomethane (RGGO-backed) renewable gas option, a lower-cost 10% green gas plus carbon-offset blend, dual fuel available.

Cons: rates aren’t published online, a premium for renewable gas, better suited to standard SME contracts than to gas specialists.

British Gas, part of Centrica, supplies business gas on fixed-term contracts alongside a defined renewable gas range. Its flagship option matches 100% of the gas you use to biomethane through Renewable Gas Guarantees of Origin (RGGOs), with a lower-cost tier backing 10% with RGGOs and the rest through approved carbon-offset projects. As one of the biggest and most familiar names in UK energy, it gives businesses genuine green-gas credentials from a large supplier.

EDF Energy

Trustpilot Rating: 4.8

Pros: Big Six scale, 1 to 3 year fixed gas contracts, budget certainty against wholesale volatility, supplies SMEs through to large businesses.

Cons: its green focus is electricity-led rather than gas-led, gas rates aren’t published, no prominent biomethane gas product.

EDF supplies business gas on Fixed for Business contracts of one to three years, giving price certainty for the term. Its sustainability proposition is strongest on electricity (nuclear and wind), so gas customers seeking green gas will find it less of a headline offering than at biomethane-focused suppliers. EDF supplies businesses of all sizes, from SMEs to large industrial and commercial users.

E.ON Next

Trustpilot Rating: 4.5

Pros: carbon-neutral and renewable gas products, 1, 2 or 3-year fixed gas tariffs, no exit fees, online account management.

Cons: SME-oriented rather than large industrial gas, its renewable gas relies partly on offsetting, large users are routed to npower within the same group.

E.ON Next supplies SME business gas on one-, two- and three-year fixed contracts and offers both a carbon-neutral gas and a renewable gas product for businesses wanting to lower their gas emissions. Its proposition emphasises simple online billing, no exit fees and a recognisable major brand. It suits smaller and medium-sized firms rather than the largest gas users, who are typically served by npower Business Solutions within the same E.ON group.

ScottishPower

Trustpilot Rating: 4.4

Pros: gas-only, dual-fuel or electricity-only options, SME gas fixable for up to four years, standard fixed gas plus tailored large-user arrangements.

Cons: its green credentials centre on electricity, no prominent biomethane gas product, gas unit rates vary by region.

ScottishPower, part of the Iberdrola group, supplies business gas explicitly as a gas-only, dual-fuel or electricity-only choice, which suits sites that only need gas. SME gas contracts can be fixed for up to four years, while larger organisations can take standard fixed gas or a bespoke arrangement. Its renewable positioning is electricity-focused, so it is a mainstream gas choice rather than a green-gas specialist.

SSE

Trustpilot Rating: 2.0

Pros: strong on larger and multi-site gas users, bespoke commercial gas contracts, both fixed and flexible frameworks, the backing of a major generator.

Cons: its renewable offer is electricity (wind and hydro), no headline biomethane gas product, less suited to the smallest micro-businesses.

SSE Energy Solutions supplies business gas across the market but is geared particularly to larger, higher-consumption and multi-site organisations, with bespoke pricing and both fixed and flexible frameworks. Its published thresholds point to a lean towards mid-market and large commercial gas users. Renewable content is delivered on the electricity side from SSE’s own UK wind and hydro assets rather than through green gas.

Octopus Energy

Trustpilot Rating: 4.9

Pros: carbon-neutral gas through offsetting, a no-standing-charge gas option, strong multi-site service and account management, transparent pricing.

Cons: it offsets rather than supplying physical biomethane, its renewable-gas product is less prominent than its electricity range, best known for electricity and smart tariffs.

Octopus Energy for Business supplies conventional business gas on fixed contracts, including no-standing-charge options useful for low-usage or seasonal sites. Rather than physical biomethane, its greener gas route is carbon offsetting, so buyers seeking injected green gas should note the distinction. Octopus is best positioned for SMEs and multi-site operators that value service, transparency and its technology-led approach.

TotalEnergies

Trustpilot Rating: 4.8

Pros: Green Gas contracts with 100% RGGO-backed biomethane matching, supplies SMEs through to large industrial users, owns biomethane production capacity, fixed contracts up to five years.

Cons: rates aren’t published, green gas is grid-matched via certificates rather than site-specific, oil-major parentage may not suit every sustainability buyer.

TotalEnergies Gas & Power is one of the UK’s largest business energy suppliers, serving around 275,000 sites from SMEs to major industrial users. Its Green Gas contracts back 100% of consumption with Renewable Gas Guarantees of Origin, guaranteeing an equivalent volume of biomethane is injected into the grid, and the group operates its own growing biomethane production. Long fixed terms of up to five years and large-user capability make it a credible option for high-consumption gas sites.

Corona Energy

Trustpilot Rating: 4.6

Pros: a dedicated business-gas specialist, one of the largest independent suppliers of industrial and commercial gas, 12 to 36 month fixed gas contracts, a dedicated account manager.

Cons: its renewable option is 100% renewable electricity rather than biomethane gas, non-domestic only, weighted towards SME and mid-market users.

Corona Energy is a long-standing business-gas specialist and one of the largest independent suppliers of industrial and commercial gas in the UK. It supplies thousands of non-domestic customers across tens of thousands of meters, weighted towards micro, small and medium businesses with an industrial and commercial tail. Fixed gas contracts run 12 to 36 months, each with a dedicated account manager, positioning Corona as a gas-heritage alternative to the major suppliers.

SEFE Energy

Trustpilot Rating: 4.6

Pros: a dedicated gas specialist with a gas-shipping licence, an Eco Gas biomethane and offset product, serves large multi-site industrial users, one of the largest UK business gas suppliers by volume.

Cons: Eco Gas relies partly on offsets rather than 100% physical biomethane, a legacy Gazprom association from before its 2022 rebrand, gas-led rather than green-first.

SEFE Energy, rebranded from Gazprom Energy in 2022 and now owned by the German government’s SEFE group, is a gas-first supplier that grew into one of the largest business gas suppliers by volume. It holds a gas shipping licence and even sells gas to other suppliers, underlining deep gas-market heritage, and serves large, multi-site industrial and commercial gas users. Its Eco Gas product blends biomethane (tracked via certificates) with carbon offsets, so it is a partial green-gas rather than a 100% physical biomethane offering.

Crown Gas & Power

Trustpilot Rating: 4.9

Pros: a business-gas specialist since 2001, genuine grid-injected biomethane blends at 10%, 25%, 50% or 100%, an award-winning independent, carbon-neutral operations.

Cons: biomethane carries a price premium and UK volumes are limited, aimed at SME and mid-market rather than the very largest users, a smaller brand footprint.

Crown Gas & Power is a dedicated business-gas specialist founded in 2001, the energy arm of the family-owned Crown Oil group, supplying gas and electricity to SMEs and mid-market firms. Its standout feature is a tiered biomethane range that lets businesses choose 10%, 25%, 50% or 100% green gas blends - genuine biomethane injected into the grid and certificate-backed, rather than carbon offsetting. That budget-flexible green-gas ladder, together with its strong independent service record, differentiates it clearly on business gas.

Yü Energy

Trustpilot Rating: 3.7

Pros: fixed-price business gas plans, multi-fuel bundling of gas, electricity and water on one bill, a rare £0.00 standing-charge gas option, multi-site contracts.

Cons: no prominent biomethane gas product, a mid-size independent with less brand recognition than the majors, its green credentials centre on electricity.

Yü Energy is an independent, business-only supplier providing gas on fixed-price commercial plans to micro-businesses, SMEs and larger corporates, and it lets customers bundle gas, electricity and water into a single multi-fuel contract and bill. A notable gas feature is its rare £0.00 standing-charge option, useful for low-usage or seasonal sites, alongside multi-site fixing. Its green positioning is electricity-led, so it is a competitive conventional gas choice rather than a green-gas specialist.

Valda Energy

Trustpilot Rating: 4.3

Pros: an SME-focused supplier, competitive multi-year gas deals, a modern app and smart-meter-native billing, transparent pricing.

Cons: its gas isn’t backed by a biomethane product, a newer entrant founded in 2019, aimed at SMEs rather than large industrial users.

Valda Energy is an SME specialist, founded in 2019, that provides business gas alongside 100% renewable electricity and positions itself as a modern, transparent alternative to the incumbents. Its strengths on gas are competitive pricing, especially on multi-year deals, plus a smart-meter-native app and clear billing. Its green credentials sit on the electricity side, so gas is supplied conventionally rather than as biomethane.

Yorkshire Gas and Power

Trustpilot Rating: 3.8

Pros: a business-only gas supplier, fast, often same-day, bespoke gas quotes, 12 to 36 month fixed plus flexible and pass-through gas products, multi-site contracts.

Cons: electricity is its renewable element rather than gas, an independent with a smaller brand profile, no domestic scale.

Yorkshire Gas and Power is a Leeds-based, business-only supplier offering commercial gas alongside 100% renewable electricity, with a reputation for very fast, often same-day, bespoke gas quotes. Gas contracts span fixed terms of 12 to 36 months plus flexible and pass-through products that expose the unit rate and non-commodity charges, with multi-site options for larger customers. It is independent and focuses on SMEs through to larger commercial organisations.

npower Business Solutions

Trustpilot Rating: N/A

Pros: a large-user business-gas specialist, sophisticated fixed, flexible and hybrid gas procurement, wholesale-market purchasing tools, multi-site management.

Cons: not available to households or smaller businesses, complex contracts less suited to simple SME needs, part of the E.ON group with SMEs routed to E.ON Next.

npower Business Solutions is a business-only supplier, an E.ON subsidiary, focused on large commercial and industrial gas users - typically firms consuming a lot of gas with higher turnovers and headcounts. It offers sophisticated procurement, from fixed and flexible to hybrid arrangements with wholesale-market purchasing tools and multi-site management, for organisations with complex requirements. It is a specialist large-user gas choice rather than an SME option.
