- You value data — the Insights portal gives you half-hourly consumption analysis
- You're in the public sector and need a supplier with strong compliance credentials

- Rock-bottom price is your only priority (TotalEnergies is mid-market, not cheapest)
- You prefer a smaller supplier with more hands-on, personal account management
- Green credentials aren't important and you'd rather not pay for renewable premiums

Citizens Advice Non-Domestic Supplier Ranking
TotalEnergies ranked 3rd out of 14 business energy suppliers in the Citizens Advice league table for Q4 2024 (October–December) — a strong indicator of complaint handling and customer service quality.
What Customers Say

— Verified CustomerReview context: TotalEnergies' 4.8-star rating from 8,000+ reviews is exceptional for a business energy supplier. Most reviews praise their webchat support and named agents.

Our Verdict
The gold standard for businesses wanting security, sustainability, and data-driven energy management
TotalEnergies Gas & Power combines the financial security of a global energy major with genuinely strong green credentials and excellent customer service. Their 4.8-star Trustpilot rating and #3 Citizens Advice ranking aren't just marketing — they reflect a supplier that takes customer experience seriously. The Pure Green product (100% solar/wind/hydro, no biomass) is one of the cleanest commercial offerings in the UK, and the Insights portal gives you proper half-hourly data access. For larger consumers, flexible purchasing and dedicated account management add real value. The trade-off? You won't get the absolute cheapest rates — smaller independents can undercut on price. And as a large supplier, you're dealing with processes rather than personal relationships for smaller contracts. But if you want a supplier that combines financial stability, genuine sustainability, and strong service — TotalEnergies is hard to beat.

Frequently Asked Questions
Common questions about TotalEnergies Gas & Power
TotalEnergies Gas & Power is part of TotalEnergies SE, one of the world's largest energy companies with 105,000 employees across 130+ countries. The UK business was originally established as AGAS Ltd in 1987 — the first independent gas contractor in the UK — and was acquired by Total in 2009. Today, they supply over 200,000 business sites across the UK, making them one of the country's largest B2B energy suppliers.
Pure Green is TotalEnergies' premium renewable electricity product, sourced 100% from solar, wind, and hydro — with no biomass or waste-to-energy. This makes it one of the cleanest commercial electricity products available in the UK. For businesses with genuine net zero commitments, Pure Green offers verifiable environmental credentials that stand up to scrutiny. It's REGO-backed and comes with documentation suitable for ESG reporting.
TotalEnergies Insights is their free online energy management portal, available to all business customers. It provides access to half-hourly consumption data, cost analysis tools, carbon tracking, and detailed reporting. For businesses serious about energy management, it's a genuinely useful tool for identifying waste, tracking trends, and supporting sustainability reporting — included at no extra charge.
Yes. TotalEnergies offers RGGO-backed (Renewable Gas Guarantees of Origin) biomethane supply for businesses wanting to reduce their Scope 1 emissions from gas consumption. Unlike electricity (where switching to renewables is straightforward), decarbonising gas is harder — RGGO certificates let you claim renewable gas without infrastructure changes. It's a premium product, but valuable for businesses with serious carbon reduction targets.
TotalEnergies offers fixed price contracts typically ranging from 1 to 5 years. For larger I&C customers, flexible purchasing arrangements are available where you buy energy in tranches over time with dedicated trading support. Contract length depends on your risk appetite — shorter terms give flexibility but less price certainty; longer terms lock in rates but reduce your ability to respond to market changes.
If your contract ends without renewal, you'll roll onto TotalEnergies' out-of-contract rates — which are significantly higher than fixed rates. Most businesses save 15-40% by renewing in advance rather than drifting out of contract. Using a broker like Smart Energy means we track your renewal dates and contact you well before expiry — so you never accidentally end up paying premium deemed rates.
Request a quote through Smart Energy and we'll compare TotalEnergies' rates against 28+ other suppliers for your specific usage. If they're competitive, we handle the entire switching process — you just sign the contract. We'll also be your ongoing point of contact, tracking renewals and helping resolve any issues. There's no charge for our service; we're paid by the supplier.
