Summer brings holidays, projects, and the odd surprise absence. If you run an office or HR function, you may be weighing up whether a temporary worker or a contractor is the smarter move. Get it right, and you keep service levels high without overspending. Get it wrong, and you risk gaps, delays, and compliance headaches.
This guide walks you through the decision. We compare temps for Business Support with HR contractors, outline typical timelines, costs and checks, and share a practical scoping checklist you can use today. We also include a light overview of the Agency Workers Regulations, when DBS checks may apply, and what to expect from notice periods.
Temp vs contractor at a glance
- Temporary staffing for Business Support: best for fast cover and flexible hours. Think reception, team assistant, office coordinator, inbox and diary support, events, and short spikes in volume.
- Contract recruitment for HR: best for defined outcomes and projects. Think HR Advisor or HR Business Partner assignments, policy rollouts, ER case work, onboarding cycles, or system implementations.
If your priority is speed to stabilise the front desk or keep diaries moving, temps are ideal. If you need someone to own a scoped piece of HR work over weeks or months with clear deliverables, a contractor is typically the better route.
Use cases and speed to hire
Business Support temps
- Ideal for holiday cover, sickness, half-term gaps, reception, inbox triage, events and campaign support, and month or year-end admin.
- Speed: often within 24 to 48 hours. At TalentYard, we regularly place trusted temps in days, with many assignments starting next business day.
- Onboarding: light touch. A quick induction to systems, key contacts, and priorities is usually enough.
HR contractors
- Ideal for projects that need continuity, such as policy refreshes, onboarding ramps, ER case handling, and People team stand-ups.
- Speed: typically 1 to 2 weeks. We scope the brief, shortlist, and schedule interviews quickly so you meet a curated set of HR professionals without slowing the project.
- Onboarding: deeper context needed on policies, systems, and stakeholders. A short knowledge transfer session helps the contractor hit the ground running.
If you need immediate cover for reception or diaries, speak with an office recruitment agency in London that can mobilise same week. For HR-led projects in London or nationwide, working with specialist HR recruitment in London or Manchester will keep your search focused and compliant.
Budgeting, rates, and how costs work
How much do agency workers cost? It depends on role type, location, and market demand. For temps, your invoice typically covers:
- The worker’s hourly pay
- Holiday pay accrual
- Employer costs such as National Insurance, plus the agency’s margin
For HR contractors, day rates or fixed-term arrangements are common. Contract structures vary and can be inside or outside IR35 depending on the engagement and tax status. We provide general guidance on IR35 but recommend taking professional advice for your circumstances.
Costs vary by city and seniority. Business Support temps are generally more cost-effective for short bursts. HR contractors carry higher day rates that reflect project scope and expertise. Both options can be budget friendly when compared to delaying essential work or stretching your permanent team too thin.
Compliance essentials, AWR, and vetting
Agency Workers Regulations (AWR) overview
- The 12 week rule for agency workers: after 12 weeks in the same role with the same hirer, temps are entitled to equal treatment on basic working and employment conditions compared with a comparable employee. This typically covers pay, annual leave, rest breaks, and similar terms.
- Before 12 weeks, certain rights already apply, including access to facilities and information on vacancies. After 12 weeks, parity on core terms usually kicks in.
DBS and other background checks
- Do agencies do DBS checks? Yes, where the role requires it. For clinics, schools, and some charities, a Disclosure and Barring Service (DBS) check may be essential. The level depends on duties and contact with vulnerable groups.
- Expect Right to Work checks in the UK for all placements. References and skills tests are routine for temps and contractors; additional vetting can be added for high-trust roles.
Notice periods
- Temps: usually light notice, often one working day once an assignment has started. Some same-day ends are possible by mutual agreement, but good practice is to hand over smoothly.
- Contractors: typically have a short contractual notice, often one to two weeks, though terms vary. Agree the notice upfront and put it in writing.
What is the 3 month rule in a job?
- There is no single statutory 3 month rule for all jobs. In practice, some fixed-term or probationary arrangements use three months as a review point. For temp and contract engagements, timelines and probation terms are set by the contract.
Onboarding that fits the assignment
For temps, focus on quick wins. Share logins, a short crib sheet, who to escalate to, and a same-day walk-through of calendars, inboxes, and the phone system.
For HR contractors, schedule a structured induction. Outline stakeholders, policies, ER pipeline, systems access, and milestone dates. A clear scope on day one pays back in speed and quality.
A simple timeline for summer cover
- Business Support temps: brief to start within days. Many roles go live in 24 to 48 hours, with interviews often optional for urgent cover.
- HR contractors: shortlist in 3 to 5 working days, interviews days 5 to 8, start in week 1 or 2 depending on availability, compliance, and notice.
At TalentYard, we tailor the process to your urgency. Temps can be in seat this week. HR contractors typically start within 1 to 2 weeks after a focused briefing and short interview cycle.
