Centrica: customer and site numbers in the United Kingdom (UK) 2014-2018
Between 2014 and 2018, the number of customers and sites supplied by British multinational utility company Centrica has been in a steady decline. In 2018, 6.9 million customers and sites were supplied gas by Centrica. However, this was a decrease of almost 1.5 million compared to just four years prior. The number of customers supplied electricity also dropped that year to 5.6 million.

Domestic market shares

British Gas is a subsidiary of Centrica and is a member of the so called “Big Six” energy suppliers and has the largest market share of both the gas and electricity supply in Great Britain. The energy and home service provider had a share of 29 percent of the gas supply market in 2018. Similarly, British Gas was the leader in the electricity supply market, with a market share of 19 percent at the end of 2018. However, these shares have been gradually decreasing in recent years.

Domestic supply revenue

Whilst Centrica’s domestic electricity supply revenue has seen an overall increase over the last decade, domestic gas supply revenues have fallen significantly. In 2013, the company recorded a revenue of 6.1 billion British pounds, but this decreased annually in the following years. By 2018, the domestic gas supply revenue stood at 3.7 billion pounds.
