British Gas Reviews, Prices & Tariffs

Is British Gas A Good Supplier? 

British Gas has a Trustpilot score of 4.2 out of 5. This is considered a great score, and their reputation matches their service. Many customers highlight great customer support but fall short of smart metering targets. 

This guide will help you understand if British Gas is the right supplier for you, considering home and business energy. 

Who Are British Gas? 

Currently supplying more than 8 million homes and businesses across the UK, they are the largest and longest-operating supplier. They are a subsidiary of Centrica, a multinational that owns multiple companies with similar interests in the market.

British Gas Business 

British Gas has been supplying businesses with their energy for many years. In 2018, British Gas Lite was created to help smaller UK businesses manage their energy online at a competitive price.

British Gas Lite is under the same ‘umbrella’ as British Gas but operates as a separate company serving small businesses with online-only smart meter energy management. Larger consumption businesses using over 150,000 kWh per year would still use British Gas for their supply.
