About

Who is British Gas Lite?

British Gas Lite is Centrica's stripped-back online-only business supplier, launched in 2018 to compete on price with challenger SME suppliers. Support is webchat-only (Mon-Fri 8am-6pm), with no general phone line — that's how Lite keeps prices below the main British Gas Business product. Single-site SMEs and microbusinesses only.

Registered as British Gas Trading Limited (Lite product line), British Gas Lite uses this legal name for Ofgem licence filings, B2B contracts and any formal communications. The trading name customers see on invoices is the shorter, recognisable form.

The company is headquartered in Windsor, Berkshire, where it runs its commercial operations, account management and regulatory liaison with Ofgem.

British Gas Lite was established in 2018. A longer track record means more years operating under Ofgem rules and a wider history of business-customer relationships.

British Gas Lite is part of the Centrica plc group, which provides shared governance, financial backing and a wider pool of expertise in wholesale trading, hedging and regulatory work.

The company is regulated by Ofgem, and complaints fall under the Energy Ombudsman alternative dispute resolution scheme,but only for microbusinesses with under 10 staff and under £2m turnover. Larger I&C customers must take complaints through commercial dispute resolution.

Review

British Gas Lite,pros and cons

Cheaper than the main brand — if you can live without a phone line. For single-site SMEs that already operate digitally and just want a Fixed-Price Plan with a smart meter, Lite often comes in cheaper than the main British Gas Business product. The downside is structural: every interaction goes through webchat, and queues during peak hours stretch (~18-25 min). Selectra score 3.0 / 5.

Strengths

  • Lower headline prices than the main British Gas Business product on most quotes.
  • Backed by Centrica plc — the same group that supplies ~12m UK homes.
  • Free SMETS2 smart-meter install for new electricity customers (within ~90 days).
  • Single fixed tariff (no confusing tariff family) for 1, 2, 3, 4 or 5 years.

Watch-outs

  • Webchat-only support — no phone line, even for billing or contract terminations.
  • No dedicated mobile app — mobile users rely on the responsive web portal.
  • Single-site only, with a microbusiness ceiling on consumption.
  • Variable Price Plan rolled into at end of fix is materially higher than the cheapest renewal.

Common questions

British Gas Lite,frequently asked questions

British Gas Lite is regulated by Ofgem under a non-domestic supply licence. Whether it suits your business depends on your annual consumption, contract term and whether you need extra services (HHM, green certification, smart-meter rollout). Always compare delivered p/kWh including VAT and CCL before signing.

Switching takes between three weeks and two months for a business contract, longer than the domestic five-working-day rule. British Gas Lite will run a credit check, request your annual consumption and a recent meter reading, and arrange the transfer with your current supplier. Supply is never interrupted during the switch.

Single Fixed Price Energy Plan, 1/2/3/4/5 years, billed by Variable Direct Debit. Rolls to Variable Price Plan or deemed at expiry.

Most UK fixed-term business contracts include termination fees if you switch mid-contract. The supplier must accept your renewal notice in the final 30 to 60 days before the contract end-date (the renewal window varies by supplier and is set out in the original contract). Outside that window you are tied in unless you pay the exit charge.

You can reach British Gas Lite through its business customer-service channels, Webchat: Mon-Fri 8am-6pm via britishgas.co.uk/business/lite. For a full breakdown of phone lines (sales, emergency, complaints, meter readings, account moves), see the British Gas Lite contact page.
