Child protection and looked after children are two distinct children's social work specialisms with different statutory functions, caseload structures, and day-to-day demands. Both sit within children's services, both require Social Work England registration, and both carry significant safeguarding responsibility. The differences between them are substantial enough to shape an entire career trajectory.

Key Takeaways

• Child protection social workers manage active s47 investigations, child protection plans, and care proceedings; LAC social workers hold the care plans of children already in the system
• CP caseloads involve higher crisis frequency and court work; LAC caseloads involve more sustained relationship-based practice with children, carers, and placement providers
• The Fostering Network's 2024 State of the Nations data confirmed 113 of 114 UK fostering services were experiencing carer shortages, driving sustained demand for LAC-experienced practitioners
• Children's social work vacancy rates stood at 17.3% FTE nationally as of September 2024, making both specialisms candidate-driven markets
• Practitioners moving between CP and LAC need to demonstrate transferable assessment and statutory skills; the regulatory frameworks differ but the core competency base overlaps significantly

What Is Child Protection Social Work?

Child protection social work sits at the acute end of the children's services system. CP social workers respond to referrals about children at risk of significant harm, lead s47 investigations, chair or contribute to child protection conferences, and manage child protection plans for children who remain at home under a formal protection framework.

The caseload is characterised by high urgency, frequent crisis response, and close court involvement. A CP social worker may be managing an active s47 investigation, contributing to care proceedings, completing a core assessment, and attending a child protection conference in the same week. Local authority children's social work vacancy rates stood at 17.3% FTE as of September 2024, with CP teams among the hardest to staff across the sector.

What does a child protection social worker do day to day?

Daily CP tasks include responding to new referrals, conducting home visits to children on protection plans, completing statutory assessments, liaising with police and health partners in MASH and strategy meetings, and updating case records to court-evidenceable standard. The pace is fast and the decisions are high-stakes: a CP social worker's judgement on any given day can determine whether a child remains at home or enters care.

The emotional weight of CP work is significant. Practitioners carry responsibility for outcomes that are rarely clean or resolved and often involve families in crisis who are resistant to statutory involvement. Building and sustaining professional relationships under those conditions requires a specific kind of resilience. Social workers who have thought carefully about how they build and maintain professional relationships under pressure bring a measurable advantage to CP practice.

What Is Looked After Children Social Work?

Looked after children social workers hold the statutory care plans of children who have entered the care system, whether through voluntary agreement, an interim care order, or a full care order following proceedings. LAC social workers are the allocated practitioner for the child throughout their time in care, which can span months or years.

The caseload involves sustained, longitudinal work with children, their birth families, foster carers, residential providers, and the multi-agency network supporting each placement. LAC social workers attend and contribute to Looked After Child reviews, manage placement moves, oversee transition planning for children leaving care, and maintain the statutory documentation that governs each child's care journey. The role requires a different kind of stamina from CP work: where CP is characterised by acute crisis response, LAC demands sustained relational consistency across long, often complex placement histories.

What does a looked after children social worker do day to day?

Daily LAC tasks include visiting children in their placements, liaising with foster carers and residential staff about the child's progress, attending placement review meetings, completing statutory visits and recording them to Ofsted-evidenceable standard, and coordinating with education, health, and CAMHS around each child's individual needs. LAC social workers also manage the legal and administrative aspects of care orders, special guardianship applications, and placement variation requests.

The relationship with the foster carer is a specific and important element of the LAC social worker's role. Where a supervising social worker is employed by the fostering service to support the carer directly, the LAC social worker holds the child's perspective and care plan. Both roles work together on every looked after child, but their accountabilities are distinct: the LAC worker is the child's allocated social worker; the SSW is the carer's.

CP vs LAC: The Key Differences

How do child protection and LAC social work differ in practice?

The functional difference is the stage of the child's journey at which the social worker is most active. CP social workers are most active before or during the threshold decision: they investigate risk, assess harm, and determine whether statutory intervention is needed. LAC social workers are most active after the threshold has been crossed: they manage the child's life in care, maintain their care plan, and work toward permanence or safe return home.

Court involvement is the clearest practical distinction. CP social workers appear in court regularly, give evidence in care proceedings, and produce court-standard assessments and statements. LAC social workers engage with court processes primarily at the point of order variation or at final hearings for permanence decisions. A CP social worker who has never experienced the pace and evidence demands of care proceedings is not yet a complete practitioner in that specialism.

Caseload size differs significantly between the two. CP caseloads in local authority teams are consistently cited among the highest in children's services, with chronic underfunding and high vacancy rates compounding workload pressure. The data on how high social work caseloads have become across UK local authorities reflects a sector-wide problem that is proportionally more acute in CP than in LAC or fostering teams.

Which Specialism Is Right for You?

Should I specialise in child protection or looked after children?

The honest answer depends on where your practice strengths and appetite for specific demands sit. CP suits practitioners who are energised by fast-paced, investigation-led work, who have strong court skills or want to develop them, and who can sustain high emotional load across short, intense bursts of intervention. LAC suits practitioners who are drawn to sustained relational work, who want to maintain a continuous relationship with a child over time, and who find meaning in the slower, longitudinal work of care planning and placement stability.

Neither is objectively harder than the other. They are differently hard. CP carries higher acute stress and court pressure; LAC carries the cumulative weight of long-term exposure to children's trauma and placement instability. Practitioners considering either specialism will benefit from reading what a career in adoption and fostering social work actually requires before making a move.

Can you move between child protection and LAC?

Yes, and it is a common career trajectory. The core assessment, statutory recording, and safeguarding competencies transfer directly between the two specialisms. The main adjustment is pace and court exposure: CP to LAC is a shift toward slower, more relational work; LAC to CP requires building or refreshing court skills and managing a higher crisis frequency. Most experienced children's social workers have worked in both settings at some point, which makes them significantly more marketable to specialist employers.

Practitioners thinking about how to become a supervising social worker will find that prior LAC experience is the most valued pathway into the fostering specialism, because the SSW role builds directly on the LAC practitioner's existing relationship with foster carers and looked after children.

Market Demand for CP and LAC Social Workers in 2026

Both specialisms are candidate-driven markets. Children's social work vacancy rates stood at 17.3% FTE nationally as of September 2024, with 44% of councils paying market supplements specifically for children's posts to compete for experienced practitioners. The DfE's agency rules, fully implemented from October 2025, have tightened the locum market for LA children's services by capping regional day rates, which is accelerating a shift toward permanent roles in both CP and LAC teams.

LAC-experienced practitioners are in particular demand in the fostering sector. The Fostering Network's 2024 State of the Nations data showed 113 of 114 UK fostering services experiencing carer shortages, which creates sustained structural demand for SSWs. The fastest route into an SSW role is via a strong LAC background, because the relational and statutory competencies transfer directly.

Charles Hunter Associates recruits across both specialisms, placing qualified children's social workers into social work recruitment permanent and temporary roles with local authorities and independent providers across the South West and nationally.

What qualifications do you need for child protection social work?

You need a degree or DipSW/CQSW in social work, current Social Work England registration, and post-qualifying experience in children's services. Most CP teams require a minimum of one to two years post-qualifying experience before carrying a full CP caseload independently. Enhanced DBS clearance is mandatory. Court skills and experience of s47 investigations are expected at senior practitioner level.

Is looked after children social work better than child protection?

Neither specialism is better; they suit different practitioners. CP social work involves higher crisis frequency, more court work, and shorter but more intense bursts of intervention. LAC social work involves sustained relational practice with children in care over longer periods. Most experienced children's social workers work in both settings across their careers. The right choice depends on where your practice strengths and appetite for specific demands sit.

What is the salary for a child protection social worker in the UK?

CP social workers in local authority teams typically earn £34,000-£44,000 depending on experience and region, with London Weighting and market supplements adding up to £6,000 in some authorities. Senior CP practitioners and advanced practitioners earn £40,000-£50,000. 44% of local authorities pay market supplements for children's posts, making the total package variable by employer. Locum CP rates in LA children's services are subject to DfE regional pay caps from October 2025.

Can a CP social worker become a supervising social worker?

Yes, though the most direct route is via LAC rather than CP. SSW roles require strong relational practice with foster carers and children in placement, which maps more closely to LAC experience than to CP investigation work. CP practitioners moving into fostering typically spend time in a LAC or children in care team first to build the placement-focused competencies that SSW roles require.

How do I find child protection or LAC social worker jobs?

CP and LAC roles are advertised on Community Care Jobs, Reed, and local authority job boards, but experienced practitioners move predominantly through specialist social work recruiters with active regional networks. Charles Hunter Associates places CP and LAC-experienced social workers across Plymouth, Exeter, Torbay, and the wider South West peninsula. Current vacancies are listed on the CHA jobs page.
