Miatta Fahnbulleh entered Parliament with more influence than most new MPs.

Before she had cast a Commons vote, she had already spent years shaping Labour's economic argument from think tanks, government policy units and Ed Miliband's opposition team. At the New Economics Foundation, she argued that weak wages, regional inequality and climate policy came from the same failed economic model. She backed public investment, stronger local economies and a faster move away from fossil fuels.

That record made her attractive to Labour's left. Her willingness to work with Starmer's leadership made her useful to the centre.

She was selected to succeed Harriet Harman in Peckham, entered Parliament in July 2024 and immediately received a ministerial job. That speed matters. Fahnbulleh did not rise through years of backbench rebellions or constituency campaigning. Labour brought her straight into government because it wanted her policy expertise and her ability to defend climate action through the language of bills, jobs and economic security.

Her first test was energy consumers.

Fahnbulleh inherited households still carrying the cost of the energy crisis, poor supplier service, failed smart-meter appointments and homes expensive to heat. She launched the first broad review of Ofgem, including proposals for easier automatic compensation when suppliers let customers down. The government also proposed bringing energy brokers under regulation after complaints about hidden commissions and mis-selling.

The most immediate help came through the Warm Home Discount. The government expanded the £150 payment to another 2.7 million households, taking expected coverage above six million. Fahnbulleh was also involved in the wider home-upgrade programme and plans to tighten energy-efficiency standards in rented housing.

Those were real measures.

They were not the Warm Homes transformation Labour had promised.

Consultations, grant allocations and new standards do not insulate five million homes. Delivery remained split between councils, landlords, energy companies and several overlapping schemes. Poor installations from earlier programmes also forced the department to intervene over defective insulation work.

The government said its plans would lift more than one million households out of fuel poverty. Fahnbulleh left the energy department before that claim could be tested. The statutory fuel-poverty target was already badly off course, and the department was still consulting on a replacement strategy rather than showing that the gap had closed.

Her move to the communities department in September 2025 widened her political brief but weakened her ownership of the energy programme. She worked on devolution, local funding, community cohesion and plans to give neighbourhood boards more influence over long-term spending. Community groups later received shares of a fund intended to rebuild local trust.

That was modest money beside the rhetoric.

Fahnbulleh left government in May 2026. Two months later, Andy Burnham brought her back as energy secretary. The comeback turned a former junior minister into the person responsible for the entire clean-energy programme.

It also placed her inside a conflict she had previously approached from the outside.

At the New Economics Foundation, Fahnbulleh opposed new fossil-fuel developments and described further investment as irresponsible. As energy secretary, she must now decide how that position fits with Burnham's greater openness to North Sea production, union warnings about jobs and pressure to approve projects linked to the Rosebank and Jackdaw fields. She has since promised a pragmatic approach and acknowledged that oil and gas will remain part of the energy mix during the transition.

Open Govt note: the July 2026 material, including Fahnbulleh's return as energy secretary under Andy Burnham and his government's energy position, is drawn from Open Govt's own record of that period, not external reporting.

That is not automatically hypocrisy. Campaigning organisations can demand a clean line. Governments inherit licences, court rulings, supply risks and workers whose livelihoods cannot be replaced by a press release.

But it is a test of what survives contact with power.

Fahnbulleh's political appeal rests on joining climate policy to ordinary living standards. Clean power, in her argument, should mean warmer homes, lower exposure to gas prices and investment spread beyond London.

The record so far is thinner. More households received bill support. Consumer protections were proposed. Retrofit money was allocated. The larger promises remain unfinished.

She now controls the department that can finish them.

The public-interest question is whether Fahnbulleh will publish the real cost, timetable and expected household benefit of the transition, or whether lower bills will remain the reward always waiting at the far end of another climate target.
