Lockdown mobility restrictions enforced by the UK Government in 2020 as a response to COVID-19 resulted in those vulnerable to domestic abuse being confined in isolation with their abusers, deprived of safe spaces with limited opportunities to contact others for help or support. This meant domestic abuse helplines became an ever more crucial avenue for victim support, with organisations seeing a substantial increase in the level of service provision required to support survivors during this time. UK charity Refuge reported a 700% increase in traffic to their website and a 120% increase in calls received during this time. Through semi-structured interviews with 11 helpline workers across services dedicated to women, men, LGBT+ populations, and BME women, this project aimed to explore the nature of calls received during lockdown. Key themes identified were (1) ‘Issues Accessing Support’, highlighting a loss of previously accessed support, uncertainty surrounding what help was available and issues around engaging with new forms of support; (2) ‘The Impact of COVID Restrictions’, with callers reporting a loss of respite and social support, legal and financial issues and the use of government restrictions as a new tool for abuse; (3) ‘Child Concerns’, with callers reporting an increase in legal complications including child contact, children as a barrier to support-seeking and children becoming witnesses or victims of abuse; and (4) ‘Pet Concerns’, with concern regarding pet care, pets as a barrier to seeking refuge, pets as emotional support, and pets as a tool for abuse (threatened or direct harm). This study provides important insight into how the nature of abuse changed during lockdown and how government restrictions increased risk of harm for this vulnerable group. This is vital in establishing long-term strategies for improving support provision and ensuring support staff have the tools required to provide adequate support to victims.
