Sutton’s Zero Carbon Energiesprong Retrofit Pilot Project

Funding has been secured for a pioneering zero carbon retrofit pilot project in Sutton.

In line with our ambitious climate change goals, homes across the borough will be transformed with the aim of achieving substantial reductions in:

  • energy consumption
  • carbon emissions, and
  • helping to improve the efficiency of properties


  • Sutton Housing Partnership (SHP)
  • Greater London Authority 
  • British Gas via the energy companies obligation programme (Eco3i)
  • The Department for Business, Energy & Industrial Strategy
  • With project support from Energiesprong UK and Turner & Townsend

Sutton’s Pilot Project 


Pilot net zero homes from Nottingham's Energiesprong project

Using the innovative Energiesprong model, 100 SHP homes will have internal and external works carried out on them, focussing on the introduction of:

  • newly constructed and highly insulated wall and roofing systems
  • new High performance glazing systems
  • solar photovoltaic panels 
  • new central heating and ventilation system

Initially, the pilot phase will deliver eight zero carbon retrofits in the Worcester Park and Coulsdon estates by Summer 2021.

The intention is to deliver an additional 92 homes, (subject to final cost negotiation) by the end of 2022 in the Coulsdon and St Helier estates.

The contract for delivery of the pilot phase has been awarded to Engie Regeneration Ltd.

This pioneering retrofit will provide:

  • for residents: warmer, more energy efficient homes and lower energy bills (depending on their energy usage)
  • for the borough: a very useful learning opportunity for the extension of retrofitting opportunities across the Borough
  • for the planet: making a significant contribution to reducing the environmental impact of our housing stock by replacing fossil fuel heating systems with largely renewably powered systems
