Retrofit London's goal is to achieve an average Energy Performance Certificate Level (EPC) of ‘B’ by 2030 through mass home retrofitting.
London’s housing stock contributes to nearly one-third of the capital’s carbon emissions, highlighting a pressing need for action. Around 80% of all homes expected to exist in 2050 have already been built, so home retrofitting, involving fabric improvements, renewable energy generation and low carbon heat sources, is essential for making London’s homes greener, warmer and more affordable to live in.
Retrofit London is part of a collaborative climate programme led by the London boroughs of Enfield and Waltham Forest. It is supported by us and the London Housing Directors’ Group (LHDG), a professional network of senior housing officers.
A collective effort and high level of political support is underway to achieve substantial carbon reductions through comprehensive home retrofit. Retrofit London is at the forefront of this change and with an estimated cost of £49 billion to elevate EPC ratings to an average of 'B' by 2030, success depends on a collaborative synergy between all parts of government and the dynamic retrofit sector.

Retrofit London housing action plan
In October 2021, the Retrofit London housing action plan was launched. It provides a detailed approach to retrofitting London's 3.7 million homes so they are an average of EPC B or equivalent by 2030. It also provides an opportunity to grow the green economy, create thousands of new jobs and provoke innovation within the sector.
Supporting the action plan is a thorough look at London’s housing stock and an assessment of the measures required to achieve the home retrofit targets, the trades requirements involved and associated costs.
Development of the plan was led by the London Housing Directors’ Group and London Councils with support from the Greater London Authority and the London Environment Directors’ Network (LEDNet). The action plan was produced on behalf of the boroughs by a consortium led by Etude, while the data analysis was undertaken by Parity Projects.
The action plan was officially launched at an event on Tuesday 26 October 2021. A recording of the event can be found on our YouTube channel.
Retrofit London housing implementation plans
Our two-year implementation plan identified key deliverables for 2023-24 and assessed the resource requirements to deliver this first phase of implementation and build a sustainable longer-term programme of work.

The Retrofit London implementation plan takes the recommended actions from the Retrofit London housing action plan and translates them into priorities and tasks with timescales for delivery over the next 12 months
Retrofit London Reports
Synchronising Retrofit and Planned Works Guidance Report
This guidance report, produced by XCO2 for London Councils, builds upon on previous work for the Retrofit London programme, by providing guidance of a pathway for the integration of Energy Efficiency Measures (EEMs) into Planned Maintenance and Capital Works (hereafter referred to as Planned Works) programmes.
The report covers key areas that can affect the synergy of EEMs and Planned Works. These include PAS 2035, Medium Term Implementation Plans (MTIPs) and the interdependencies between EEMs and Planned Works, including a specific focus on the strategic and technical considerations.
Community powered retrofit report
New research, commissioned by Retrofit London, and conducted by Dark Matter Labs and Home Energy Action Lab, has explored the potential of community-led approaches.
