Locum social workers moving into children's services roles from October 2025 must hold a minimum three years' post-qualifying experience in a UK local authority setting. The Department for Education rule closes the door on newly qualified social workers taking locum children's posts. This guide explains what counts, what doesn't, and where the workarounds sit.

Key Takeaways

• The rule applies only to children's services locum posts, not adult social work.
• Post-qualifying experience must be in a UK local authority, not private, NHS, or overseas.
• Three years is a rolling total across LA posts, not a single continuous placement.
• ASYE year counts toward the three-year total where the ASYE was completed inside an LA.
• Non-eligible candidates can still take permanent LA roles or move into adult social work locum.

What the DfE 3-Year LA Experience Rule Actually Says

The Department for Education introduced statutory rules in October 2025 requiring every children's services locum social worker to hold at least three years' post-qualifying experience in a UK local authority setting. The rule sits inside the wider agency reform package that also introduced regional day-rate caps and a four-week notice period standard.

The stated purpose is workforce stability. DfE and the Local Government Association argued that agency turnover in children's services was disrupting statutory casework, and that a minimum experience threshold would push newly qualified staff into permanent posts before they moved into agency work. The government's response to the Stable Homes Built on Love agency social work consultation sets out the underlying policy reasoning.

When did the 3-year LA experience rule take effect?

The rule took effect from 1 October 2025 for all new children's services locum placements booked on or after that date. Placements booked before 1 October 2025 continued under the previous terms until contract expiry. Extensions after 1 October 2025 fall under the new rule, and agencies must verify eligibility before extending any children's contract.

Which social work sectors does the rule apply to?

Children's services locum social work is the only category the DfE rule covers. Adult social work sits outside the DfE scope. Early years and fostering supervising social worker roles sit outside the rule. Permanent LA posts, including permanent children's services, are also exempt. Independent fostering agencies, private children's homes, and charity sector work fall outside the rule.

What Counts as Qualifying Local Authority Experience

Qualifying experience means paid post-qualifying practice in a UK local authority children's services setting. The Assessed and Supported Year in Employment (ASYE) counts as year one, provided it was completed inside an LA. Three years can be built up as a rolling total across multiple LA posts, and gaps between placements do not reset the count.

Verification sits with the placing agency at booking. Charles Hunter Associates verifies experience directly with previous LA HR teams and via Social Work England registration records. The three-year total must be evidenced by written references, not self-declared on CV. Community Care's 2025 agency survey found roughly 12% of self-declared three-year candidates could not produce written LA verification when challenged.

Does the ASYE year count toward the three-year total?

An ASYE year completed inside a UK local authority fills year one of the three-year total. ASYE completed in a private, voluntary, or independent setting does not count for children's services locum eligibility, even though it counts for Social Work England registration renewal. This is the most common misunderstanding among candidates approaching the threshold.

Do NHS, private, or overseas roles count toward the three years?

NHS, private provider, and overseas social work posts do not count toward the DfE three-year LA total. The rule specifies UK local authority experience. This creates a specific issue for social workers returning from overseas practice or moving in from NHS mental health teams. They may have decades of experience without a single day of qualifying LA post-qualifying practice.

What about supervising social worker or fostering roles?

IFA-based roles count where the caseload includes statutory children's services activity commissioned by an LA. Purely private fostering work does not count. Fostering roles inside an LA children's services team count in full. The three-year total needs to be documented specifically, and Charles Hunter Associates checks post scope with the previous employer at reference stage.

How Agencies and Councils Verify Your Experience

Verification happens at compliance stage, before shortlist. Every candidate placed into a children's services locum post must produce written references from previous LA employers covering the full three-year period. Gaps in written reference must be evidenced by contract records, timesheets, or Social Work England registration data. Councils cannot lawfully accept a candidate without full verification.

Charles Hunter Associates runs the verification inside the agency, absorbing what would otherwise be council HR overhead. The risks of placing a locum social worker without full vetting cover why councils that skip verification carry legal exposure under the new DfE rules.

What documents do you need to produce for verification?

Candidates need three sets of documents at compliance stage. First, current Social Work England registration with a clean fitness-to-practise record. Second, Enhanced DBS with barred lists. Third, written references from every LA employer covering the three-year total, dated, signed, and on official letterhead. Overseas police checks apply where the candidate has lived outside the UK in the last five years.

How is Social Work England fitness to practise verified?

Every agency must check Social Work England's online registration record directly, which shows any active or pending investigations. Agencies must check registration status at booking, at contract extension, and annually on renewal. Renewing your Social Work England registration covers the CPD and fitness-to-practise declaration timelines.

What to Do If You Don't Yet Have Three Years

Social workers approaching but not at the three-year threshold have four practical routes. First, complete the three years in permanent LA practice, then move to locum. Second, take adult social work locum work, which sits outside the DfE rule. Third, take independent sector work where the rule doesn't apply. Fourth, hold a permanent children's services LA post while banking the qualifying time.

The most common route is a hybrid. A permanent LA post gets the candidate to the three-year total on standard NQSW-to-SW pay scales. Once eligible, the candidate moves to locum for the 30-50% gross hourly uplift. Transitioning between locum and permanent social work covers the timing decisions that matter at each stage.

Can you take adult social work locum work with less than three years' experience?

Two years' post-ASYE experience is the standard threshold under most council PSL agreements for adult SW locum work, and no LA-specific requirement applies. A social worker with two years' post-qualifying experience, whether that experience is LA, NHS, or private, can take adult SW locum work. This is the primary escape valve for candidates ineligible for children's services locum.

What about permanent children's services LA roles?

Newly qualified and sub-three-year social workers can still take permanent children's services LA roles. The DfE rule applies only to agency locum bookings, not to permanent employment. Newly qualified social workers targeting locum work should treat permanent LA work as the qualifying pathway, not as a detour.

Frequently Asked Questions

Does the 3-year rule apply to adult social work?

The DfE 3-year LA experience rule applies only to children's services locum posts. Adult social work locum work operates under separate PSL agreements typically requiring two years' post-ASYE experience, with no LA-specific requirement. Adult SW locum candidates can hold NHS, private, or independent sector experience toward the two-year total.

Can overseas social work experience count toward the three years?

Overseas social work experience does not count toward the DfE three-year LA total. The rule requires UK local authority post-qualifying practice specifically. Overseas-trained social workers must complete Social Work England conversion, then three years of UK LA practice before becoming eligible for children's services locum work.

If I have three years permanent, can I start locum immediately?

Once the three-year UK LA total is documented and verified in writing, you're eligible for children's services locum bookings from that date. Charles Hunter Associates runs the verification process pre-registration so eligible candidates can accept a shortlist inside the standard 5-10 working day timeline.

Does independent fostering agency work count as LA experience?

Independent fostering agency work counts where the SW's caseload includes statutory children's services activity commissioned by a local authority. Purely private fostering work does not count. The distinction matters because IFA supervising social worker roles can be either category depending on the specific caseload and commissioning arrangement.

What happens if I'm found ineligible after starting a placement?

Ineligibility discovered mid-placement means immediate contract termination and potential referral to Social Work England if the candidate made false declarations at compliance stage. Councils that place ineligible candidates carry statutory liability under the DfE rules and may face wider agency contract review. Full agency verification pre-registration prevents this exposure.
