Out of 16,262 incidents of domestic abuse in the 12 months, only 2,026 cases were taken up by the Crown Prosecution Service, giving a prosecution rate of just 20 for every 100 crimes.
This is down from 23 the previous year.
Across England and Wales, domestic abuse incidents increased by 6 per cent, while the number of prosecutions fell by 5 per cent.
Charities have described the figures as "shocking", and called for more action to ensure abusers are brought to justice.
Katie Ghose, chief executive of Women’s Aid, said: "This failure by the police to consistently protect survivors is a major concern and is likely to damage the survivor’s trust in the police.
"We know from our work with survivors that it often takes a woman a lot of courage to report domestic abuse and it is rarely the first incident of domestic abuse that she has experienced."
The ONS said that improved accuracy in the recording of domestic abuse could be behind the increase in incidents.
However, the National Police Chiefs' Council explained that reports had risen "considerably" over the last 8 years, while cuts to police resources had left officers struggling to provide the best response to victims.
Deputy Chief Constable Louisa Rolfe, NPCC lead on domestic abuse, said: "Domestic abuse is an increasing proportion of emergency call demand in every force and therefore resources are stretched.
"When we take longer to respond to a call, investigate a crime or arrest an offender, victims are less likely to have confidence in the justice process.
"However, I’m heartened that many forces are striving to protect more victims and arrest and prosecute more offenders."
The number of domestic abuse incidents recorded by Nottinghamshire Police fell by 5 percent , going against the national trend.
Of the cases recorded by Nottinghamshire Police, 64 percent were logged as crimes.
The rest remained as incidents, which means an officer investigating a report of domestic abuse determined an offence had not taken place.
Domestic abuse-related crimes accounted for 11 percent of all crimes dealt with over the year, and 30 percent of violent offences.
Only 15 in every 100 crimes led to a conviction.
Sandra Horley, chief executive of Refuge said: "It is scandalous that so many women’s lives are torn apart by current or former partners.
"When so few victims get justice, it doesn’t encourage others to go through what can be a traumatic process."
A Home Office spokesman said the Government would soon publish a "landmark" Domestic Abuse Bill which would look to transform how the crime is dealt with.
He said: “We would urge anyone who is the victim of this horrific crime to come forward and report their experiences, safe in the knowledge that the state and the justice system will do everything it can to both support them and their children, and pursue their abuser."
