Performance Information

Performance Information

A second key method of understanding risk in the community is through analysing historical performance information. This allows the Service to allocate resources in the both the short and long term to manage risk.

Each quarter, DFRS reviews performance against its existing measures, publishing information and commentary at all levels of the Service. These reports provide up-to-date accounts of performance and incident analysis, and are scrutinised by members of the Fire and Rescue Authority through the Governance and Performance Working Group.

Incident Activity Mapping Portal

The Service provides up-to-date information on incidents to staff and the public on its Incident Activity Mapping Portal. This mapping shows, incident details for the public to review and know incident activity in their community.

Risks from fire

In addition, incident information can be used to calculate the ‘risks from accidental dwelling fire’ to communities using the formula:

Risk = Probability of fire x Severity of fire

The change in probability (all fires) and severity (accidental dwelling fires only) over the last five years is shown below:

Incidents attended




% change over five years


All fires

Rate per 10,000 capita





All dwelling fires

Rate per 10,000 dwellings





Accidental dwelling fires

Rate per 10,000 dwellings







Fire Severity






% change over five years






















To calculate the reduction in risks from accidental dwelling fire, the residual probability of fire (all fires - 0.93) and residual severity from fire (high severity - 0.54) are multiplied to identify the overall reduction in risk from fire.

Based on historical data, the risks from high severity fire in Derbyshire have therefore reduced by 50% over the last five years. This is an overall calculation for the county, and local calculations (shown in the Emergency Response Review) show rates of change higher and lower than this overall figure.

Fire Statistics Monitor

The Government’s publication Fire Statistics Monitor provides key statistics on fires, casualties, false alarms and non-fire incidents attended by fire and rescue services in England. This information enables the Service understand the context of its own performance and trends within the national picture. To review information from the Fire Statistics Monitor, please click here.


Benchmarking (with Family Group 4)

DFRS also benchmarks its performance with other fire and rescue services. Derbyshire Fire & Rescue Service is part of Family Group 4 (FG4) and compares its performance against these other fire and rescue services who have similar characteristics in terms of size, population, density and industry. By benchmarking, the Fire & Rescue Authority can provide context to the Service’s performance and can see if other services have lower rates of fire. Where there is opportunity, information is shared on best practice to reduce risk in the community.

Below are a series of tables which compare some of the 2015/16 incident performance with that of other fire and rescue services in FG4:

Primary fires (fires involving people or property) per 100,000 population



  • Derbyshire reported 121.19 primary fires per 100,000 capita against a FG4 average of 134.86.
  • This is a 5.3% increase since 2014/15. The charts show an increase in all but two of the FG4 FRSs, the average among the group being a 6.9% increase.
  • When compared to 2012/13, Derbyshire saw a 0.24% reduction in 2015/16.
  • Based on the number of incident in the last reporting year, Derbyshire ranks 5th out of the 16 FRSs that provided data.

Accidental dwelling fires per 10,000 dwellings



  • DFRS reported 9.86 accidental dwelling fires per 10,000 dwellings against a FG4 average of 10.60 fires.
  • This is a 0.60% reduction since 2014/15 and a 4.46% reduction since 2012/13. 

Fatalities in accidental dwelling fires per 100,000 population



  • Derbyshire reported 0.39 deaths in accidental dwelling fires per 100,000 capita, against a FG4 average of 0.29.
  • This is a 105.26% increase since 2014/15. The group has seen an average increase of 16.00%
  • Based on the number of deaths from accidental dwelling fires in 2015/16, DFRS ranks 13th out of the 14 FRSs that submitted information.

Injuries in accidental dwelling fires per 100,000 population



  • Derbyshire reported 3.78 injuries in accidental dwelling fires per 100,000 population in 2015/16 against a FG4 average of 3.14.
  • Derbyshire reported no change in the rate of injury against a FG4 average reduction of 4.85%. However, over the last 4 years, Derbyshire has seen a 48.01% reduction

Deliberate secondary fires (smaller outdoor fires, not involving people or property) per 10,000 population



  • Derbyshire reported 7.23 fires per 10,000 capita in 2015/16 against a FG4 average of 13.39. This puts Derbyshire 6th out of the 15 FRSs that submitted data in this category.
  • All but 3 FRSs in FG4 have seen an increase in the rate of secondary fires in the last year.

Fires in non-domestic premises per 1000 premises



  • Derbyshire reported 4.83 fires per 1,000 non-domestic premises in 2015/16 against a FG4 average of 7.16. This puts Derbyshire 2nd out of the 15 FRSs that submitted data in this category.
  • Derbyshire is one of several FRS that has seen an increase in rate of fires in non-domestic premises.
