Overview

Bristol Energy was a local-authority-owned energy supply business created by Bristol City Council as part of a wider effort to address climate change, energy security and local economic development. The council decided in principle to establish an energy company in 2010, approved a business plan in 2015, and founded Bristol Energy in September 2015. The company began accepting customers in February 2016 and supplied gas and electricity to domestic and business customers throughout the United Kingdom. The business was designed to combine commercial energy retailing with public-sector objectives, including support for renewable generation and the potential retention of profits for local investment. It also sought public-sector contracts, including the supply of energy to Bristol City Council. In 2018, British Gas narrowly won the council's supply contract on price, although Bristol Energy subsequently regained portions of the council's gas and electricity business. The company reported progress in renewable energy: in 2019 it stated that 79% of its supplied energy was generated from renewable sources. It also obtained a grant of approximately €1.9 million from the European Investment Bank and the European Commission for renewable-energy work undertaken with Plymouth City Council. Despite these initiatives, Bristol Energy required substantial financial support from its council owner and was not expected to become profitable until 2024 according to reporting cited in its public history. By August 2019, Bristol City Council had provided approximately £37.7 million in funding. The company also faced management changes and growing concern about the risks associated with the council's commercial investments. Peter Haigh, the first employee and chief executive, left in late 2018 and was replaced by finance director Marek Majewicz. Majewicz departed in March 2020 and was replaced by Allan Booth, described in contemporary reporting as a turnaround specialist. Bristol City Council placed the business for sale in May 2020. Its commercial customer accounts were sold to Yü Energy in August 2020. In September, the Bristol Energy brand and approximately 155,000 residential meter points were sold to Together Energy, while the renewable-generation portfolio and commercial feed-in-tariff customers were sold separately to F&S Energy in October. Bristol Energy therefore ceased to operate as an integrated municipal supplier, although the name continued as a domestic energy brand within Together Energy. The wider Together Energy business was unable to secure additional funding or a buyer during the wholesale energy-price crisis that intensified in late 2021. On 18 January 2022, Together Energy Retail announced that it was ceasing to trade. Its domestic customers, including customers associated with the Bristol Energy brand, were subsequently transferred to British Gas. Bristol Energy is consequently a defunct energy-supply brand rather than an active independent supplier. The corporate restructuring also separated the former Bristol Energy company and its liabilities from the entity that carried the Bristol Energy name after the transaction.

History

Bristol Energy originated in Bristol City Council's climate and energy policy. In 2010, the council decided in principle to establish an energy company as part of its Climate Change and Energy Security Framework. A formal business plan followed in February 2015 and was approved by the council cabinet in July of that year. Bristol Energy was founded in September 2015 as a wholly council-owned company, held through Bristol Holding Limited. It began accepting customers in February 2016. The company supplied gas and electricity to households and businesses across the United Kingdom. Its public-sector ownership distinguished it from conventional private suppliers, while its stated rationale included renewable-energy development, energy security and the possibility of creating a commercial return for local government. Bristol Energy also pursued council and other public-sector supply contracts. In spring 2018, it lost the contract to supply Bristol City Council after British Gas offered a slightly lower price. It later won back part of the council's gas business in November 2018 and regained the council's electricity contract in February 2019. Management changed during this period. Peter Haigh, Bristol Energy's first employee and chief executive, left in December 2018. Marek Majewicz, previously the finance director, succeeded him. In January 2019, the company announced a grant of about €1.9 million from the European Investment Bank and the European Commission for renewable-energy work undertaken with Plymouth City Council. Bristol Energy stated that 79% of its energy supply in 2019 came from renewable sources. In May of that year, it entered a partnership with The Big Issue, and the chief executive later said the company had employed two people who had previously experienced homelessness. The business nevertheless became a significant financial and governance issue for its owner. A July 2019 council risk register gave a high-risk rating to the category covering long-term commercial investments and major capital projects, including Bristol Energy. By August 2019, Bristol City Council had provided approximately £37.7 million in funding, and the company was not expected to become profitable until 2024 according to the cited public reporting. In March 2020, Majewicz left his managing and finance director roles and Allan Booth became managing director. Booth had been described as a turnaround specialist. Bristol City Council placed Bristol Energy on the market in May 2020. The company was subsequently dismantled through several transactions. In August, approximately 4,000 business customer accounts were sold to Yü Energy. In September, Together Energy acquired the Bristol Energy brand and approximately 155,000 residential meter points. The residential operation continued under the Bristol Energy name, but no longer represented the original integrated municipal business. Richard Orna, formerly Bristol Energy's head of information services, became managing director of the acquired operation. In October 2020, F&S Energy bought the renewable-generation portfolio, including power-purchase agreement contracts, as well as commercial feed-in-tariff customers. The transferred portfolio had approximately 91 MW of contracted capacity. Corporate legal entities were also reorganised: the former Bristol Energy Limited changed its name to BE 2020 Limited and retained the earlier company's debts and liabilities, while another entity was renamed Bristol Energy Limited for the post-sale brand operation without taking on those historical liabilities. The brand's final period was shaped by the United Kingdom wholesale energy crisis that began in autumn 2021. Together Energy was unable to secure sufficient additional funding or find a buyer. On 18 January 2022, Together Energy Retail announced that it would cease trading. Its domestic customers were subsequently transferred to British Gas. Bristol Energy therefore ended as an active retail brand, following the collapse of the wider supplier group and the earlier sale of its business, residential and renewable assets.
