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.

Peter Griffin

Principal analyst

Joining Regen in 2025, Peter provides expertise on building and heat decarbonisation and is helping accelerate the integration of heat and building modelling into our insights across the energy landscape. Prior to this, Peter worked with Parity Projects (now part of Cotality) as an analyst and product lead for its local authority housing models. From this, he learned first hand the frustrations and challenges of delivering retrofit and heat decarbonisation in local government. He is now building those insights into Regen's analysis and policy recommendations to accelerate the efficient delivery of retrofit across the UK.
