Powering up low-carbon homes

We want to accelerate the pace of upgrading the nation's homes and buildings to be warm, low carbon and affordable to heat. Improving the fabric efficiency of homes and switching to low-carbon heating are necessary building blocks for healthy and resilient communities. To level up our housing, we will need a combination of market interventions, strong policy, and national and local government to work together.

To achieve this, we are addressing several critical barriers currently slowing down the transition to low-carbon homes across the country:

  1. Electricity costsHigh electricity costs are impeding heat electrification and leaving increasing numbers of people in fuel poverty.
  2. Preparation for electrificationDelayed investment in distribution network reinforcement has left the networks unprepared for the scale of electrification needed.
  3. Customer journey There is a lack of trusted, balanced and bespoke advice available to homeowners, resulting in difficult installation journeys.
  4. Supply chain shortagesThe existing gas engineering workforce is shrinking and there is a lack of investment in growing a skilled, low-carbon heating industry.
  5. A coordinated approach Planning and delivery models for communal and coordinated interventions are under developed, yet they are critical for achieving economies of scale.

Senior energy analyst

Sophie has a masters in Engineering Design from the University of Bristol, where she specailised in civil structures, renewable energy and sustainable systems thinking. Having completed multiple engineering work placements across buildings and rail, she joined Regen in 2020 as an energy analyst, focusing on challenges around whole system decarbonisation and, in particular, heat.

Sophie has a keen interest in policy and the wider impacts of energy on places, health and livelihoods. She co-leads two of Regen strategic focuses – just transitions and retrofit. She also runs the ESN’s safety and sustainability working group, which aims to drive progress on ethics issues associated with stationary batteries.

Sophie is also proudly interdisciplinary and passionate about the power of storytelling, which is why she set up and runs the Regen Art Lab. She also uses her graphic design expertise to support the team to tell compelling data stories.

Two of Sophie’s most significant works include the second edition of National Grid’s 'A day in the life of 2035' report and supporting the Welsh Government to develop their Heat Strategy in partnership with the Carbon Trust. Currently, she is researching the role of Welsh cultural organisations in addressing the climate and nature emergencies.
