Climate emergency

The Council has set a target to make all its estate and operations; including fleet - net zero by 2030.

Corporate buildings are defined as those the council both owns and manages directly. These are places where we deliver services ourselves and have full control over how energy is used.

The Council is currently undertaking net zero carbon surveys to inform the specific interventions which need to be implemented alongside building use optimisation.

Our Local Area Energy Plan (LAEP) sets out how an area can reduce carbon emissions and transition to a low-carbon, net zero energy system. It provides an understanding of the nature, scale, rate, and timings of changes needed for the transition to a net zero energy system.

The Greater London Authority commissioned the delivery of a Phase 1 LAEP for the West London sub-region. Completed in 2023, this strategic plan provided an overview of the existing energy systems across the nine West London boroughs and Old Oak and Park Royal Development Corporation (OPDC). It identified priority areas for action to help the region reach its net zero carbon targets.

Building on this regional evidence base, the London Borough of Hounslow developed its own detailed, borough-level Phase 2 LAEP. Finalised in Summer 2025, the plan outlines a clear pathway to transition to a net zero energy system in Hounslow. It identifies key interventions and timelines, prioritises areas for action, and aims to ensure a fair and inclusive transition, supporting both residents and local businesses.

District Heat Network

District Heating Networks (DHN) are a low-carbon method of supplying heat to homes and businesses throughout the borough. Excess heat energy that is extracted from renewable sources such as the ground or a water body, or from industrial processes such as manufacturing, is supplied to residential homes and businesses through a network of pipes.

Following feasibility study in 2023, detailed proposals for the initial phase of a district heat network was developed, which was approved by cabinet in February 2025. The Phase 1 of the network will take heat from  Thames Water Mogden sewage treatment works to supply low-carbon heating to buildings in Isleworth and Brentford. The subsequent phases will expand this to supply heating to Hounslow and Feltham, with potential to extend to Hounslow.

The heat network proposal will make important contribution to wider borough net zero targets, delivering low-carbon heating at lower overall cost, while also improving local air quality and mitigating grid constraints.

Further detail can be found in the Hounslow Heat Network project cabinet report.

Net Zero Neighbourhoods

Net Zero Neighbourhoods is an approach to improving energy efficiency in domestic properties, and decarbonising or reducing emissions from domestic energy, by adapting homes through retrofit and delivering wider neighbourhood improvements to support more sustainable lifestyle choices.

In 2023, Hounslow Cabinet approved the development of a feasibility study to explore this approach, to determine whether this can be a viable way for the borough to influence emissions reduction across homes in the borough and support residents with adapting their homes for the future, whilst also creating more comfortable living environment and greener better-connected neighbourhoods.

Adapting homes at the scale and pace required, can be prohibitively expensive for the Council and its residents, and this approach looks at a new way of funding the delivery of these improvements, by attracting private investment whilst ensuring residents’ priorities for their neighbourhoods and homes are captured from the early stages of development.

You can access the cabinet paper with further detail on the feasibility study.

Hounslow Green Investment: Supporting a Greener Future Together

As part of our commitment to tackling the climate emergency and achieving net-zero carbon emissions by 2050, Hounslow Council has launched the Hounslow Green Investment initiative. This innovative scheme is designed to raise £5 million to fund a range of local environmental projects that will contribute to a cleaner, greener, and healthier borough. Open to everyone - residents, businesses, community groups, and investors from outside the borough - this opportunity allows you to support Hounslow's climate goals with investments starting from just £5.

The first raise is live from June to September 2025, and full details on how to take part can be found on our Green Investment page. For more in-depth information, including a breakdown of projects, an FAQ, and a survey to share your views, please visit our Hounslow Green Investment page. Your voice and your support are essential in helping us shape a sustainable future for all who live and work in Hounslow.

Community Energy Fund

Hounslow Council is committed to tackling the climate emergency and achieving net-zero carbon emission by 2050. To help achieve this goal, Hounslow Council runs the Community Energy Fund – a decarbonisation grant tailored to community groups to simultaneously reduce their carbon emissions and save on energy bills. Each round of funding offers £150,000 in total, with each community group eligible for up to £40,000 for their project. Project’s include installation of Solar PV, Air Source Heat Pumps, glazed windows, insulation and more.  

The Community Energy Fund runs two intakes per year. View full details including application timings and documents here. If you have any questions or need help with your application email environmental.strategy@hounslow.gov.uk. 

The London Borough of Hounslow is developing a Climate Change Resilience Plan (CCRP) to assess the risks of climate change on the Council’s services, assets and people in the borough. The CCRP will consolidate existing plans to build on work already underway in the borough and identify any gaps to deliver new actions. The CCRP will also seek to reduce climate vulnerabilities in the borough, geo-spatially and identify groups adversely sensitive to the climate impacts. 

For certain areas of climate resilience Hounslow as a local authority has a lead role working with partners to develop plans and put in place adaptation measures to appropriately manage the risk of and impact of extreme events.  These include 

• Local Flood Risk Management Strategy (LFRMS) - This strategy outlines how the council and other key stakeholders such as the Environment Agency will manage local flood risk in the borough. 

• Surface Water Management Plan (SWMP) - This plan assesses surface water flood risk in the borough and how to manage this including integration of Suds 

• Thames Estuary 2100 Flood Risk Management Plan - The Thames Estuary 2100 (TE 2100) Plan was developed by the Environment Agency and provides strategic direction for managing flood risk in the Thames Estuary.

• Green and Blue Infrastructure Strategy - This strategy is an essential component of resilience. It sets out programmes in our green and blue spaces to both mitigate against climate change and support adaptation.  

• Nature Recovery Action Plan (NRAP) - This plan identifies the priorities for nature recovery in the borough and sets out a programme of strategic actions to conserve, promote and increase biodiversity across the borough and develop resilience.
