Why choosing the right supply teacher agency matters
Before 7:00am, one absence can affect registration, interventions, behaviour routines and staff workload. In that moment, a school needs more than a list of available supply teachers; it needs a supply teacher agency that can respond clearly, safely and quickly.
A teacher recruitment agency relationship is strategic. It affects safeguarding, pupil outcomes, budget control, parental confidence and staff well being. London also has high demand across primary schools, secondary schools and SEN settings, shaped by recruitment pressure, travel patterns and retention challenges in the education sector.
The right school staffing agency London partner can cover daily supply, training days, maternity cover, long-term absence and permanent teaching jobs. Teaching roles include permanent, long-term, and daily supply positions, giving leaders more flexibility than a purely reactive model.
Impact Teachers is a London-based recruitment agency with over 20 years of experience in education recruitment. Over 20 years, Impact Teachers has placed high-quality educators in schools, and its mission of empowering teachers to transform education for every student underpins the service you can learn more about through the Impact Teachers homepage.
Safeguarding, compliance and vetting standards
Safeguarding is non-negotiable. Schools remain responsible for ensuring supplier compliance with Department for Education standards, and agencies conduct safeguarding checks mandated by the Department for Education. Enhanced DBS checks are mandatory for supply teacher agencies to ensure safety, and agencies process Enhanced DBS checks to ensure teacher safety before placement.
Schools should expect evidence of:
- identity checks and right to work;
- enhanced DBS with children’s barred list;
- qualifications, including verification of Qualified Teacher Status where relevant;
- professional references covering past teaching history;
- explanations of employment gaps;
- overseas police checks where appropriate.
Agencies check legal status to work in the UK during the hiring process, and agencies need to validate the right to work for teachers via visas or passports. Agencies verify qualifications such as Qualified Teacher Status before placement. Agencies require professional references covering past teaching history.
Ask how checks are stored, updated and shared before a teacher, teaching assistant or cover supervisor arrives. Many agencies process payroll directly through PAYE systems, while agencies may use PAYE systems or third-party umbrella companies for payroll. UK Agency Worker Regulations mandate equal pay for teachers after 12 weeks in the same role, so long-term bookings need careful monitoring.
Agencies should hold REC Audited Education Status to meet safeguarding regulations, or clearly evidence equivalent safeguarding processes. Schools can read more about how Impact Teachers works with schools on the schools page.

Candidate quality and role suitability
Candidate quality and rigorous vetting are crucial when choosing an agency. Quality is not only QTS or subject knowledge; it includes classroom management, punctuality, adaptability, safeguarding awareness and alignment with the right school culture.
A good education recruitment agency London partner should understand phase, key stage, curriculum, behaviour policy, local area and staffing needs. Candidates should be perfectly matched to the setting, not simply available.
Different roles need different evidence. A science teacher, maths specialist or religious studies teacher for KS4 or KS5 requires subject confidence. Early career teachers may need more support. Teaching assistants support teachers in primary and secondary schools, and understanding how a teaching assistant can support the teacher effectively helps schools and agencies maximise impact in the classroom. SEN schools require specialized teachers for special educational needs, and aspiring SEN teachers often need specific skills in autism, SEMH, communication and sensory support.
Useful questions include:
- How does the interview process assess teaching standards?
- Are references linked to recent classroom performance?
- How is underperformance handled?
- How are school feedback and agency work records reviewed?
- How are teachers and support staff briefed before arrival?
Teachers submit availability and preferences to agencies for placement management. Agencies match available teachers with school requirements based on immediate needs, and teachers must respond quickly to accept same-day roles from agencies. Impact Teachers aims to build continuity, so daily supply can become reliable work, long-term cover or a permanent teaching job where appropriate.
Speed of response for urgent school cover
Supply agencies function in real-time to address school staffing emergencies. London schools often need cover confirmed between 6:30am and 7:30am, and the difference between a calm timetable and merged classes can be a quick, honest update.
An efficient process should include one contact, fast acknowledgement, realistic timeframes and transparent communication if a booking is difficult. Agencies may pre-book teachers for planned absences like training days, but urgent absence needs a different operating rhythm.
Ask whether the agency can provide:
- qualified teachers;
- cover supervisor support;
- teaching assistants;
- SEN support staff;
- short-term and long-term cover;
- staff for primary and secondary schools.
For planned roles, expect CVs, shortlists, interviews and, where useful, trial days. Impact Teachers has dedicated consultants for London schools and can support immediate cover or planned recruitment through the contact page.
Local knowledge of London schools and boroughs
Agencies in London specialize in recruiting for the unique educational landscape of the capital. A local supply teacher agency London partner understands Hackney, Haringey, Southwark, Croydon, Harrow, Barnet, Newham, Ealing, Westminster and the home counties are not interchangeable.
Travel matters. Matching by postcode alone can fail if transport routes are poor. Strong agencies consider realistic journeys, start times, parking, local train reliability and the expectations of academies, faith schools, free schools, maintained schools and sen schools.
Local knowledge also helps with teaching posts in London, job opportunities in shortage subjects, teaching vacancies in the local area and high demand periods. Teachers can explore special needs education job opportunities across London boroughs with various established London-based agencies, and schools can compare how agencies understand their borough context.
For market awareness, Reeson Education has been operating since 2006, Reeson Education has built a reputation for reliability and trust, and Reeson Education has a gold-standard REC Award for safeguarding. Academics is one of the UK’s largest teaching agencies, and Academics provides teaching jobs in primary, secondary, and SEN schools. The Supply Room offers placements within two weeks of signing up, and The Supply Room provides consistent communication and support to teachers. These examples show why schools should test claims with evidence, not rely on brand size alone.

Support for teachers, SEN staff and classroom support roles
A modern recruitment company should support the full workforce mix: class teachers, experienced teachers, cover supervisors, teaching assistants, intervention tutors, pastoral staff and SEN specialists. Support staff play a vital role in children’s lives, especially for pupils with EHCPs, speech and language needs or behaviour plans.
Professional development is essential for teacher satisfaction and success. Teachers can access professional development resources through recruitment agencies, and Reeson Education offers a broad portfolio of professional development. Impact Teachers provides ongoing professional development opportunities and ongoing support for education professionals.
Impact Teachers supports overseas teachers relocating to the UK. Teachers from around the world are attracted to the UK’s education system, and guidance on transitioning from teaching abroad to the UK plus Impact Teachers’ ongoing support can make the relocation process smoother. Teachers receive assistance with visa and safeguarding checks, helping them understand expectations in London classrooms.
Schools can review Impact Teachers’ breadth across primary teacher jobs, secondary teacher jobs and SEN teacher jobs.
Procurement confidence and framework access
Many schools, MATs and local authorities want procurement confidence, especially when agency spend is under scrutiny. Agencies charge schools a daily rate for supply teachers and pay a portion to teachers, so agencies must be transparent about their daily margin rates and fees. Payment for supply teachers in London varies from £130 to £275 per day, depending on role, experience, borough, urgency and contract length.
School business managers should understand supply teacher pay rates in 2024/2025 and ask:
- Is the agency on RM6376 or an equivalent framework?
- How are margins, pay and fees explained?
- How are cancellation terms handled?
- How is Agency Worker Regulations compliance tracked?
- How does the agency support budget planning?
RM6376 provides a structured route for education recruitment procurement; see the official Government Commercial Agency RM6376 page. You can also read Impact Teachers’ RM6376 announcement and the guide to how schools can use RM6376 or STaER.
Involve governors, trust finance teams or local authority procurement where multi-school arrangements are being reviewed.

FAQs about choosing a supply teacher agency in London
How many supply teacher agencies should a London school work with?
Some schools use a small panel of trusted supply teaching agencies for consistency; others use a wider pool for hard-to-fill subjects. Review fill rates, safeguarding evidence, feedback and value for money annually.
What information should a school share when requesting cover?
Share school postcode, phase, key stage, subject, timetable, dates, start time, behaviour expectations, safeguarding contacts and essential experience. Include whether the role is for a science teacher, cover supervisor, teaching assistant, SEN specialist or another post.
How can schools evaluate whether supply staff are effective?
Use short feedback forms, punctuality notes, department comments and behaviour feedback. Sharing both praise and concerns helps agencies build a trusted pool for each school.
Can supply staff move into permanent roles at the same school?
Yes, many schools use long-term supply teaching as a route to assess fit before permanent recruitment. Understanding a day in the life of a secondary school supply teacher in the UK can help leaders design roles that work well for both staff and students. Check contracts, framework terms, transfer fees and qualifying periods before making an offer.
How far in advance should schools book long-term or permanent cover?
For maternity leave, exam-year classes or known departures, start as early as timetables and budgets allow. Early notice gives agencies time to source suitable teachers, arrange interviews and reduce disruption.
