Only one police force in the UK is meeting a target to answer 90% of 999 calls in under 10 seconds, new data has shown.

Avon and Somerset Police was the only force to meet the standard, according to national statistics released for the first time by the Home Office.

Forty-three forces failed to meet it over the six months from November 2021 to April 2022.

Overall, 71% of 999 calls were answered within 10 seconds.

Humberside Police recorded the worst number, with only 2% of calls answered in under 10 seconds. South Yorkshire Police answered 17%, Durham Police 41%, North Yorkshire 44% and Gloucestershire 49%.

Police Scotland aim to have a mean answering time of under 10 seconds, and recorded 10.1 over the period.

Home Secretary Priti Patel said “the public deserve to know that their local police force will be at the end of the phone, ready to leap into action at seconds’ notice to protect them from harm”.

“Fundamentally, publishing this data is about driving up standards in our incredible emergency services even further, so that the public can have every confidence in the police’s ability to save lives and keep our streets safe,” she added.

“We can now see where forces are excelling and where vital improvements need to be made and I thank the police for their commitment to ensuring we maintain the best emergency services in the world.”

The National Police Chiefs’ Council (NPCC) lead for contact management, Assistant Chief Constable Alan Todd, said a lag in connecting calls can contribute to waits but that “this isn’t for a member of public to resolve”.

“We want the public to have access to the data as part of policing being open and transparent,” he added.

“This is the first time police forces and the public have been able to see the time it takes to answer 999 calls from the call being made by the public, it being connected to the police by BT and local providers, to it being answered by police call handlers.”

The Association for Police and Crime Commissioners local policing leads Alison Hernandez and Jeff Cuthbert said the data shows “the demand for policing and the volume of calls” across the country.

“Police and Crime Commissioners are committed to supporting excellence in policing and will use this data to continually drive forward improvements and hold the police to account on behalf of the public,” they added.

It comes after the BBC reported that freedom of information requests obtained from 22 police forces in England and Wales suggested officers are now 28% slower to attend Grade 1 emergencies.

This equates to taking three minutes longer on average to arrive at serious incidents.

The BBC said responses from 19 forces in England and Wales suggested they were 44% slower to arrive at serious incidents than in 2013.

The broadcaster also reported that the number of recorded crimes leading to a charge or court summons for a perpetrator fell for the last seven consecutive years, up to March 2021. Between 2015 and 2021 it fell by 40%.

Here is a list of the average answering time for 999 calls between November 2021 and April 2022 for every territorial police force in the UK, except the City of London.

The data only covers 999 calls intended for the police and does not include 999 calls for other emergency services.

The list is ordered alphabetically and reads, from left to right: name of police force; average (mean) answering time in seconds; percentage of calls answered under 10 seconds; percentage of calls answered between 10 and 60 seconds; percentage of calls answered after 60 seconds.

All percentages have been rounded to the nearest whole number.
