Miatta Fahnbulleh, the Energy Secretary, recently addressed the Labour Party Conference in Liverpool, setting out her department's priorities for the energy sector. A central theme was her commitment to reducing household energy bills, stating that "a mark of her success or failure would be whether she could get bills down and said she would do so". Fahnbulleh also criticised Reform UK and the Tories for their approach to climate issues, asserting that they "would eventually ‘bow’ because they were on the ‘wrong side of history’". This speech, delivered on Monday 28 September 2026, underscored Labour's broader strategy to reshape the UK's energy landscape, focusing on affordability, security, and climate action1.

Labour's energy policy aims to transform Britain into a "clean energy superpower". This ambitious vision seeks to address both the climate crisis and the nation's energy security concerns by significantly increasing domestic renewable energy generation.
The drive for a 'clean energy superpower'
The party's goal is to achieve a zero-carbon electricity system by 2030, a target significantly more ambitious than the government's previous 2050 aim. To reach this, Labour plans to double onshore wind capacity, triple solar power, and quadruple offshore wind by the end of the decade. This push for clean power is intended to help British households save on their energy bills and reduce the UK's vulnerability to volatile international fossil fuel markets.
Addressing climate change and energy security
The shift towards a clean energy system is presented as a dual solution to the climate crisis and energy insecurity. By investing heavily in home-grown renewable sources, Labour aims to reduce the UK's reliance on imported fossil fuels, which have contributed to high energy costs. This strategy is designed to make the UK energy independent and more resilient to global energy price shocks.
Labour's energy strategy is built around several core initiatives designed to drive investment, improve infrastructure, and enhance energy efficiency.
Great British energy: a publicly owned company
A cornerstone of Labour's plan is the establishment of Great British Energy (GBE), a new publicly owned energy company. GBE is tasked with accelerating the development of clean, domestically produced energy and supporting the UK's net-zero commitments. It will partner with industry and trade unions, co-investing in leading technologies such as green hydrogen, tidal energy, and floating offshore wind.
Investment in renewable energy projects
Beyond GBE, Labour plans significant investment across the renewable energy spectrum. This includes doubling onshore wind, tripling solar power, and quadrupling offshore wind capacity. The party also intends to invest in carbon capture and storage, hydrogen, and marine energy, ensuring the necessary long-term energy storage infrastructure is in place.
The Warm homes plan: boosting energy efficiency
The Warm Homes Plan is a key initiative focused on improving energy efficiency in British homes. Labour has pledged to invest an additional £6.6 billion over the next parliament to upgrade five million homes, aiming to cut bills for families. This plan offers grants and low-interest loans for insulation, solar panels, batteries, and low-carbon heating systems. The management of this programme will be devolved, giving mayors and local councils greater control over its delivery, and supporting local community energy initiatives.
A primary objective of Labour's energy policy is to reduce household energy bills, a concern highlighted by Miatta Fahnbulleh.
Strategies for reducing energy costs
Labour's approach to lowering energy costs centres on increasing the supply of cheaper, home-grown renewable energy and improving energy efficiency. By transitioning away from expensive, volatile fossil fuels, the party anticipates a long-term reduction in bills. They aim to help families save on their bills, not just in the short term, but for good.
The role of renewables in bill reduction
Renewable energy sources like wind and solar are often cited as being cheaper than fossil fuels for electricity generation. By significantly expanding the UK's capacity in these areas, Labour expects to drive down the wholesale cost of electricity, which should, in turn, translate to lower consumer bills.
Energy efficiency upgrades and savings
The Warm Homes Plan is specifically designed to tackle high energy bills through home improvements. Upgrading homes with better insulation, solar panels, and heat pumps can drastically reduce energy consumption. For example, Labour estimates that a social-rented two-bedroom semi-detached home could see significant annual savings with insulation and solar panels, while an owner-occupier three-bedroom home might also save hundreds of pounds annually with solar panels and a battery.
Labour's energy policies extend beyond household bills, aiming to reshape the entire UK energy sector.
Grid modernisation and infrastructure investment
The National Grid has been identified as an obstacle to deploying cheap, clean power and electrifying industries. Labour plans to work with industry to upgrade the national transmission infrastructure.
