How do I see more local detail?

Either use the search to find your postcode, street or a local landmark which will show incident at the most local level. Alternatively, you can drag and zoom the map to change the level of detail. The current zoom level will be indicated by the indicator in the "Map info" panel on the right of the screen.

Why can't I see the wards and sub-wards for the whole of London?

At its most detailed level the map contains a large amount of information that can cause even the most efficient web browsers to run very slowly. To ensure the best performance the map only shows smaller detailed areas at a lower zoom level. It is possible to show ward detail for a specific borough by selecting "Compare levels\ times in selected borough" in the "Refine Map" menu.

What do the colour codes on the Incident Map mean?

Areas of London are colour coded to show how the count of incidents\arrival times compares to the average for London.

The following ranges are used on the map where the local count\arrival times compared to the average for London is:

Why isn't my postcode recognised?

Between 200 and 1000 postcodes in London are added each month, making it difficult to keep the maps completely up to date. Postcode records are maintained by The Royal Mail and are updated periodically on this website as they are received. However there will inevitably be some gaps and delays. Typically these missing postcodes are less than 2% of all the postcodes in London.

Why does Incident Mapping website run slowly on my computer?

The LFB Incident Mapping website contains a lot of information, so the speed of the map depends on the computer and internet browser you are using. A newer or different web browser may help if the maps seem slow or unresponsive.

What areas are shown on the map?

The map shows boroughs and electoral wards. In the future, we might provide data at sub-ward level (also known as Lower Super Output Areas). For more information see the Glossary.

What do the incident numbers mean?

All Incidents are measured by total count per area over a rolling 12 month period (for example 1st January to the 31st December).

What do the arrival time figures mean?

The arrival times for the 1st and 2nd fire engine are measured by the average time per area over a 12 month period. We measure our performance at dealing with emergency incidents by the time it takes a first and second fire engine to arrive. For some calls (e.g. an automatic fire alarm sounding, or to release a person shut in a lift car) we would only send one fire engine initially. For many incidents (e.g. a dwelling fire), we will initially send two fire engines. There are many occasions when we will initially send more than two fire engines, and often additional fire engines are despatched once the full nature of the incidents is determined by initial crews.

How frequently is the LFB Incident Mapping website updated?

Data is updated monthly. The new month is added to the incident count and the yearly figures are rolled on one month. For example an update to include January’s figures would mean the time range would change from 1st Jan - 31st Dec to 1st Feb - 31st Jan

Has the Information Commissioner's Office been consulted about the map?

Yes. The MPS who set up the original Crime Mapping website has consulted fully with the Information Commissioner's Office (ICO) and is satisfied that the MPS has considered the data protection issues and that there are sufficient safeguards to protect the identity of those who use LFB services as represented by the incidents shown on the map. The MPS will continue to seek advice from the ICO as the map is developed.

If you want to make a request for information which is not currently available in the data on this site you can do so through the Information Access Team or visit our access to information pages on the London Fire Brigade website for further details.

How have you determined which areas are in which colour codes?

Boroughs are ranked from 1 to 33 and wards 1 to 649 based on the number of incidents \ average arrival times over a rolling 12 month period. The borough or ward ranked 1 has the highest number of incidents.

The boroughs and wards are grouped into 5 categories. The High Category contains the highest ranked boroughs\wards and the Low or None Category contains the lowest ranked borough\wards
The number of incidents \ average arrival times in each category adds up to 20% of the London total.
