Heat Street: local system planning

UK Power Networks' Heat Street project is a first of its kind research project to help communities map out their Net Zero carbon future at street level. The project took a data-driven look into the future to help local authorities and community energy groups forecast and plan for future deployment of energy efficiency and low carbon heating solutions. For FAQs on this visualisation, please scroll to the bottom of the page.

Select from the scenarios and other drop downs to the left of the map to explore the Heat Street data.




Select year ():



Select No and the colour scale at the bottom of the map will stay the same for all three years: 2020, 2030 and 2050.

Select Yes and the colour scale at the bottom of the map will change depending on the year you have selected. This will help improve contrast for each area within your chosen year.

Frequently Asked Questions

Why does this map only show data for the years 2030 and 2050?

To create the most detailed insights possible, heat street specifically focused only on how the energy system might change in the next ten years (2030) and by the Government’s Net Zero target (2050). However, we publish detailed yearly forecasts as part of our Distribution Future Energy Scenarios research. You can view our DFES here.

What is the source of the data presented on this map? Can I access it?

We use a wide range of sources and government databases for this research. This include the Energy Performance Certificate (EPC) database and the English Housing Condition Survey. All of our data is publically available on this page.

What are your underlying assumptions in the data and how have you approached modelling?

We created both a housing stock model based on a wide range of data sources and a techno-economic model which forecasts how energy efficiency measures and low carbon heating systems could be used. You can view our project methodology and all of our sources in full on page 4 of our project report, here.

How did you choose the different scenarios?

We based our modelled scenarios on Distribution Future Energy Scenarios, which is similar but wider-scope forecasting research which we publish annually. We also built our scenarios to be in line with industry-wide forecasting efforts such as National Grid’s Future Energy Scenarios (FES) research.

Why didn’t you conduct your analysis for all of the UK?

Our license areas only cover London, the South East and East of England, so we focused our research specifically on our patch. Our area is very diverse and includes many different properties and communities, so we believe there may be some broad trends that could be consistent nationwide.

How do you define fuel poverty?

Analysis completed in this project was done based on the BEIS 2020 Fuel poverty statistics (which are based on 2018 data). This used the Low Income High Costs (LIHC) indicator, which considers a household to be fuel poor if:

- they have required fuel costs that are above average; and

- were they to spend that amount, they would be left with residual income below the poverty line.
