Direct SEN recruitment and agency use both have genuine advantages for London schools. This guide compares both approaches across cost, time, quality and continuity to help SENCOs and headteachers make better staffing decisions.
London schools can source SEN staff through direct recruitment or through staffing agencies, or through a combination of both. Each approach has genuine advantages and disadvantages, and the right choice depends on the specific staffing situation, the urgency of the need, the budget available and the importance of continuity for the pupils involved. Understanding when direct recruitment makes sense and when agency use is the better choice helps London SENCOs and headteachers make more effective staffing decisions.
SENDhelp supplies specialist SEN teachers, teaching assistants and support staff to schools and provisions across London and the surrounding counties. Whether you need cover today or are planning ahead, we can help you find the right person quickly.
Direct SEN recruitment offers several advantages over agency use for the right situations. Lower ongoing cost: once a worker is employed, the cost per hour is lower than agency rates because no agency margin is included. Continuity: directly employed workers who remain in a school long term develop the relationships, knowledge and investment in pupil outcomes that rotating agency workers cannot match. Culture fit: you choose your own workers based on their values, personality and fit with your school’s SEN approach. Long-term reliability: a committed directly employed SEN TA is a more stable resource than an agency worker who may be offered another placement at any time.
Agency use offers advantages that direct recruitment cannot match in certain situations. Speed: an agency can confirm a placement within hours, compared to 4 to 8 weeks for direct recruitment. Flexibility: agency workers can be engaged for specific placements without the commitment of a permanent employment contract. Specialist access: agencies can source workers with specific SEN skills that may not be available in the local direct recruitment market. Compliance outsourcing: the agency handles DBS, references and training verification. Contingency cover: agencies provide a reliable fallback when directly employed staff are absent and internal cover is insufficient.
Direct recruitment makes the best sense when: a role is permanent and ongoing, particularly for EHCP-specified provision that will continue for the duration of the EHCP; the school wants to build a stable, consistent SEN team; the cost of sustained agency use in a specific role would exceed the cost of direct employment over the expected period of the need; the school has the time to run a proper recruitment process; or the school has identified an agency worker or other candidate they want to convert to direct employment.
Agency use makes the best sense when: covering a planned or unplanned absence and there is no available internal cover; filling a specialist role urgently; sourcing a worker with specific SEN skills not readily available through direct recruitment; managing a short-term increase in SEN demand; trialling a candidate before offering permanent employment; or maintaining SEN provision continuity during a direct recruitment process. Agency use should be purposeful, time-limited and managed actively rather than being the default response to any SEN staffing gap.
Direct SEN recruitment in London requires a targeted approach to attract suitable candidates in a competitive market. Effective approaches include: advertising on specialist education and SEN job boards; using the school’s social media presence and community networks; offering competitive pay rates that reflect London costs; providing a clear and attractive role description including the SEN context and the type of provision the role will support; moving through the selection process quickly to avoid losing candidates to other schools; and providing a positive candidate experience that reflects the school’s values.
The most effective SEN staffing model for most London schools combines both approaches: a core of directly employed SEN TAs and LSAs delivering ongoing EHCP-specified provision and SEN support; a small internal pool of flexible SEN workers who can cover planned and unplanned absences; and a trusted agency relationship for contingency cover, specialist placements and cover while direct recruitment is underway. This model provides the continuity and cost-effectiveness of direct employment with the flexibility and speed of agency supply, at an overall cost that is lower than relying on agencies for all SEN staffing needs.

Direct recruitment makes the best sense for permanent, ongoing roles particularly for EHCP-specified provision, for roles where you want to build long-term continuity for specific pupils and for situations where the cost of sustained agency use would exceed the cost of direct employment. It takes longer than agency use but produces a more stable, committed and typically cheaper workforce over time.
Agency use is the right choice for urgent cover when there is no internal resource available, for specialist roles needed quickly, for short-term or variable demand that does not justify a permanent appointment and for cover while a direct recruitment process is running. Agency use should be purposeful and managed actively, not a default response to any SEN staffing need.
Direct SEN recruitment in London typically takes 4 to 8 weeks from advertising a vacancy to the worker’s first day. The process includes advertising, shortlisting, interviewing, DBS checking and onboarding. The timeline can be shortened somewhat with efficient processes but is always longer than agency supply. Agency cover while a direct recruitment process runs is the most effective way to maintain continuity during a vacancy.
