Cadogan | Decarbonisation audits

Greengage was appointed by Cadogan to deliver a series of decarbonisation audits for several buildings across the estate to support their net zero target and refurbishment programme.

The purpose of these audits was to review the existing buildings usage, energy systems and establish indicative energy consumptions. From this, a series of recommendations were identified that would initially support EPC rating improvement in line with MEES requirements. In addition, these audits’ findings would support the decarbonisation strategy of the estate in line with their Net Zero target.

The Cadogan Estate is a thriving, cosmopolitan district in the heart of Chelsea, London, covering 93 acres of the Royal Borough of Kensington and Chelsea. It includes prime residential and commercial properties of varied age and architecture, with 15 acres of gardens.

Key outcomes identified:

  • Practical energy reduction initiatives that could be applied across numerous buildings across the estate.
  • Recommendations included lighting, building fabric, HVAC and operational energy savings with indicative costs, carbon savings and payback periods. Each ranked in order of priority and impact for buildings assessed.
  • Where building use might be changed, opportunities and initiatives were recommended to maximise energy efficiency in the change of use.
  • Indicative embodied carbon budgets for refurbishments in line with LETI guidance.
  • Initiatives identified have been used by the client to establish a retrofitting works programme and budget across the directly managed buildings within the estate.


“We are pleased to be working with Greengage to help us understand the energy and carbon impact of our buildings. Their technical insight has established a series of reduction initiatives and interventions that will address building thermal performance and improve operational efficiencies, supporting our work to reduce carbon emissions across the estate.” Kate Neale, Head of Sustainability
