Almost 50 suspected killings may have occurred during that time as well, says the party.
Across England and Wales, police were forced to issue nearly 1,800 domestic violence protection notices and arrest over 64,000 suspects.
The Lib Dems have warned things are likely to get worse as much of the country gets plunged into Tier 3 and Tier 4 restrictions, especially as the end of the festive season often sees a surge in cases anyway.
South Cambridgeshire councillor Ian Sollom has written to Airbnb in the UK asking it to offer spare accommodation to people at risk of domestic abuse.
In June, Airbnb in Ireland announced a partnership with Safe Ireland and Women’s Aid to offer domestic violence survivors emergency accommodation.
Using its hotel partners and spare accommodation, Airbnb Ireland provides temporary accommodation, free of charge, when specialist emergency accommodation or refuge is not available.
But the initiative only covers the Republic of Ireland.
Sollom says: "As well as implementing the full force of the law, we must provide refuge for people at risk of this horrific crime—they must know that they are a priority.
"Strict measures will be in place for a long time yet, and with the threat of a third national lockdown potentially … this poses an even more horrifying reality for some people.
"But if this Covid crisis has taught us anything, it's the immense power of people coming together and supporting each other.
"The reality is that we must do all we can to make sure that anyone at risk of domestic abuse is guaranteed a safe and consistent place to stay and Airbnb can offer that.
"That's why I've written to Airbnb here in the UK to ask them to urgently follow their Irish counterpart's brilliant initiative and offer up any free accommodation to anyone at risk of domestic abuse. I strongly urge Airbnb to take action and play its part in the Coronavirus crisis."
A spokesperson for Airbnb says: “Airbnb is committed to supporting communities around the world impacted by the ongoing pandemic and has recently launched Airbnb.org dedicated to facilitating temporary stays in times of crisis.
“This year, in the UK, the Airbnb community has provided more than 1,200 stays for NHS staff and we have supported domestic violence survivors in Ireland alongside Women’s Aid and Safe Ireland.
“We are continuing to monitor the impact of this ongoing project.”
