Cordis Bright are delighted to have worked with Foundations – the What Works Centre for Children & Families – and The Drive Partnership on a feasibility study of Restart. Restart is a multi-agency intervention designed to improve responses to domestic abuse in low-to-medium risk families. This feasibility study aimed to understand Restart’s programme theory and participant pathways, and to determine the feasibility of a future impact evaluation using experimental or quasi-experimental designs. The feasibility study ran from April 2024 to August 2025.

About Restart

Restart aims to improve responses to domestic abuse. It was developed by the Drive Partnership (SafeLives, Respect, and Social Finance) and is delivered by Cranstoun and Respect. The programme adopts a whole-family, multi-agency approach targeting low-to-medium risk domestic abuse perpetrators who have involvement with children known to Children’s Social Care (CSC). Its primary goals are to hold perpetrators accountable for their actions, support behaviour change, and to ensure the safety and wellbeing of (ex-) partner and child victim-survivors.

Restart operates across six London Boroughs (Barking and Dagenham, Camden, Croydon, Havering, Sutton, and Westminster). It consists of four key components:

• Safe & Together model implementation: This is a system-level approach aimed at improving domestic abuse responses by ensuring that accountability is placed on perpetrators while keeping adult and child victim-survivors safe.
• One-to-one domestic abuse perpetrator intervention: This is a four- to eight-week behaviour change programme focused on improving motivation and readiness for change among low-risk-low-harm perpetrators.
• Support pathway for victim-survivors: This involves parallel support for (ex-) partner victim-survivors, including risk monitoring and safety planning.
• Optional housing pathway: Provision of temporary accommodation for service users to ensure that victim-survivors can remain safe at home, guided by the wishes of the victim-survivor.

Approach to the feasibility study

The feasibility study took an exploratory, "test and learn" approach, with a focus on building capacity for future impact evaluation. It focused on understanding the programme’s delivery and determining the feasibility of future impact evaluations using experimental or quasi-experimental designs.

The evaluation addressed key questions, including:

• To what extent is Restart’s Theory of Change rooted in evidence?
• To what extent has Restart been implemented and delivered in line with key dimensions of implementation?
• To what extent does Restart show evidence of promise?
• To what extent would an experimental or quasi-experimental methodology be feasible and acceptable?
• To what extent do key findings vary by EDIE characteristics?

The study employed both qualitative and quantitative methods, including interviews and observations in three case study sites, and analysis of monitoring, activity and outcomes data across all six boroughs. It also explored potential benefits for children who, while not direct participants, are the intended primary beneficiary of Restart.

In addition, the Cordis Bright team worked closely with a group of adult and young people experts by experience, who co-facilitated fieldwork and informed analysis and reporting.

Next steps

Our findings highlight how Restart can help CSC and Early Help address perpetrator behaviours that are often misunderstood and insufficiently addressed in current practice. The report underlines the importance of collective action to prioritise and support evaluation of promising programmes like Restart. There is a vital window of opportunity ahead of the forthcoming Violence Against Women and Girls (VAWG) strategy. Embedding robust evaluation within this strategy will be critical to improving outcomes for child and adult victim-survivors, and to driving meaningful change in how systems respond to domestic abuse. Restart feasibility findings are shaping Foundations’ plans for future impact evaluations. Foundations is scoping an impact evaluation of domestic abuse workforce training programmes to continue strengthening the evidence base.
