Elephant and Castle

E.ON is supporting major redevelopments in London


E.ON is supporting a major redevelopment in London with strategic design advice to help it achieve its carbon targets, develop heat networks and complete advanced energy master planning. 

The Elephant and Castle development is one of only 20 projects worldwide endorsed by ex-US President Bill Clinton’s Climate Change Foundation. 

The consultancy work started in March 2011 to analyse energy demand and provision for the development.
The project will take 15 years to complete, cost £1.5bn and create new parks and squares for London, whilst meeting the highest standards in sustainability.

The redevelopment

It’s one of the largest redevelopments in Europe delivering 2,500 new homes, shops and restaurants over 25 acres of the London borough of Southwark, centred on the famous Elephant and Castle roundabout.

We’re helping to deliver:

  • Affordable, low carbon homes and businesses 
  • Ambitious carbon emission reduction targets 
  • Assessment of the latest technologies and innovations
  • Long-term commercial viability for the scheme.

The project

Initially E.ON undertook a high level energy strategy to assess the different technology options and configurations for the Elephant and Castle development.
E.ON’s consultants are now working with the principal developer to advise on how to meet stringent planning requirements for the energy strategy and retain Bill Clinton’s enthusiastic support of the project.
The energy strategy

The energy strategy will provide:

  • Commercial and technical designs of heat networks
  • Outline to planning consent
  • Energy consumption assessments
  • Carbon emission analysis 
  • Compliance to national, regional and local planning policies.

E.ON’s Consultancy Services team is also meeting with regional and local authorities to present the energy strategy on behalf of the client.
The Consultancy Services team will write the energy strategy which will form part of the outline planning application for the development. The plan also ensures that CO2 reduction targets are achieved for the buildings standards legislation of Code for Sustainable Homes and Zero Carbon Homes.
The technology

A heat network provides heat from a low carbon energy centre to any number of homes and buildings from a network of underground well-insulated pipes fed by a central source. A heat network can supply heat to housing developments, whole towns or even entire cities.

At the heart of the energy centre is the primary generating plant, such as a combined heat and power (CHP) unit, which produces heat and hot water and also generates electricity at the same time.


  • Reduced carbon emissions 
  • Reduced heating bills 
  • No gas boilers in individual properties means there are no boiler maintenance or replacement costs 
  • Hot water on demand 
  • Emergency call-out service and helpline for customers 
  • Remote reading of heat meters enables accurate billing
