The Complete Guide to Temp and Contract Recruitment in the UK

Why Temp and Contract Recruitment Matters

Permanent recruitment gets all the attention, but temp and contract is where some of the smartest recruiters build their best revenue. While perm placements are one-off fees, a temp desk generates recurring income week after week. One contractor billed at £25 per hour with a £5 margin generates £200 per week, £10,400 per year, for as long as they remain on assignment.

Scale that to 20 or 30 contractors on billing and you have a significant, predictable income stream. The temp market in the UK is worth over £40 billion annually, and it continues to grow as companies prioritise flexibility.

But temp and contract recruitment comes with complexity that perm recruitment does not. There are regulations, compliance requirements, and financial structures that you need to understand properly. Get it wrong and you face fines, reputational damage, or both. This guide covers everything you need to know.

Temp vs Contract: What is the Difference?

These terms are often used interchangeably, but they describe different things:

Temporary workers are typically employed by the agency (or through an umbrella company) and assigned to a client. They are paid hourly or daily, usually for lower-to-mid-level roles, and can be on assignment for anywhere from a single day to several months. Think warehouse operatives, admin temps, customer service staff.

Contractors are usually more senior or specialist professionals engaged for a specific project or period. They often operate through their own limited company (PSC) or an umbrella company, and they command higher day rates. Think IT contractors, interim finance directors, project managers.

The recruitment process is similar for both, but the compliance requirements, pay structures, and margins differ significantly.

AWR: The Agency Workers Regulations

The Agency Workers Regulations 2010 (AWR) are the most important piece of legislation for UK temp recruiters. In simple terms, AWR says that after 12 weeks in the same assignment, an agency worker is entitled to the same basic pay and conditions as someone directly employed by the client in a comparable role.

What AWR Covers

• Basic pay: After 12 weeks, the temp must receive at least the same pay as a directly employed comparable worker
• Working time: Same entitlement to annual leave, rest breaks, and maximum working hours
• Collective facilities: From day one, temps must have access to things like canteens, childcare facilities, and transport services
• Job vacancies: From day one, temps must be informed of any permanent vacancies at the client

The 12-Week Clock

The 12-week qualifying period starts from the first day the worker begins their assignment with the client. If the assignment is broken by a gap of more than six weeks, the clock resets. Gaps of six weeks or less do not break the continuity.

This is important for margin calculations. Before the 12-week mark, your margin might be healthy. After week 12, if you need to increase the worker's pay to match AWR requirements, your margin could shrink unless you renegotiate the charge rate with the client.

Practical Tip

Track the 12-week date for every temp on your books. Set calendar reminders at week 10 so you have time to assess the impact and, if necessary, renegotiate rates with the client before AWR kicks in. Most good CRM/timesheet systems can automate this tracking.

Umbrella vs PAYE: How Temps Get Paid

There are two main payment models for temporary workers in the UK, and understanding the difference is essential.

PAYE (Pay As You Earn)

Under PAYE, the agency employs the worker directly. You handle payroll, deducting income tax, National Insurance, and any other deductions before paying the worker. You are also responsible for employer's NI contributions and any statutory payments (SSP, holiday pay, etc.).

Pros: Simple for the worker. Clear employment relationship. You control the payroll process.

Cons: Higher administrative burden. You carry the employer's NI cost, which affects margins. You take on employer liabilities.

Umbrella Companies

An umbrella company becomes the employer of the temp worker. The agency pays the umbrella company, and the umbrella handles all payroll, tax deductions, and statutory obligations. The worker is technically employed by the umbrella, not by your agency.

Pros: Reduces your administrative burden and employer liability. The umbrella handles all payroll compliance. Works well for workers on multiple short assignments.

Cons: The worker's take-home pay is lower because the umbrella takes a fee (usually £20-30 per week). Some umbrella companies have questionable practices, so due diligence is essential. You need to ensure the umbrella is compliant and reputable.

Which Should You Use?

For most temp agencies, the approach is to use PAYE for your regular, long-term temps and umbrella companies for short-term or one-off assignments where the admin cost of putting someone on your own payroll does not make sense.

IR35: What Recruiters Need to Know

IR35 is the anti-avoidance legislation designed to prevent workers from paying less tax by working through their own limited company (PSC) while effectively being an employee. Since April 2021, the responsibility for determining IR35 status for medium and large businesses in the private sector sits with the end client, not the contractor.

How IR35 Affects Recruiters

If a role is determined to be "inside IR35," the worker must be taxed as an employee. If the agency is in the payment chain, you may be responsible for deducting tax and NI. If the role is "outside IR35," the contractor can continue to work through their PSC and manage their own tax affairs.

The Key Factors for IR35 Determination

• Control: Does the client control how, when, and where the work is done? More control suggests inside IR35.
• Substitution: Can the contractor send a substitute to do the work? A genuine right of substitution suggests outside IR35.
• Mutuality of obligation: Is the client obliged to offer work and the contractor obliged to accept it? If yes, it looks more like employment.

As a recruiter, you need to understand IR35 well enough to advise clients and contractors, even though the determination itself is the client's responsibility. Many contractors will not work with agencies that do not understand IR35 properly.

Margin Calculations for Temp Recruitment

Understanding your margins is critical. Here is a simplified breakdown of how temp margins work:

This gross margin of £6.28 per hour then needs to cover your overheads (office, software, staff, insurance) before you see any profit. On a 40-hour week, this example generates £251.20 gross margin per contractor per week.

The key to profitability in temp recruitment is volume. One contractor at a £6 margin is modest. Thirty contractors at a £6 margin is £7,536 per week in gross margin. That is why temp desks can be incredibly profitable once they reach scale.

Compliance Essentials

Running a temp desk without proper compliance is a disaster waiting to happen. Here are the non-negotiable requirements:

• Right to work checks: You must verify every worker's right to work in the UK before they start. Keep copies of documents on file. Since the introduction of the points-based immigration system, this includes checking share codes for EU nationals.
• Key information document (KID): Since April 2020, you must provide every temp with a KID before they start, detailing the type of contract, pay rates, deductions, and fees.
• Employment business regulations: As an employment business (which is what a temp agency is legally), you must comply with the Conduct of Employment Agencies and Employment Businesses Regulations 2003.
• Insurance: You need employers' liability insurance (minimum £5 million), professional indemnity insurance, and public liability insurance.
• GDPR: All candidate data must be processed lawfully. Check our GDPR guide for details on using AI tools while staying compliant.

Building a Temp Desk From Scratch

If you are starting a temp desk or adding temp capability to an existing perm desk, here is a practical roadmap:

Step 1: Choose Your Niche

Temp works best when you specialise. Industrial and warehouse, office and admin, healthcare, education, hospitality, and IT contracting are all strong markets in the UK. Pick one, learn it deeply, and build your reputation there before diversifying.

Step 2: Get Your Back Office Right

Temp recruitment requires robust systems for timesheets, payroll, invoicing, and compliance tracking. You can either build this in-house or outsource to a back-office provider like Parasol, Brookson, or Giant. Many startup temp agencies use an outsourced payroll solution until they have enough volume to justify bringing it in-house.

Step 3: Build Your Candidate Pool

Temp candidates need to be available quickly, often within 24-48 hours. Build a database of pre-screened, compliant candidates who are ready to go at short notice. This is where AI-powered sourcing and pipeline building becomes especially valuable. For practical guidance on building candidate pipelines, see our pipeline guide.

Step 4: Win Your First Clients

Start with companies that have frequent, predictable temp needs. Distribution centres, call centres, manufacturing plants, and care homes are all high-volume temp users. Approach them with a clear value proposition: pre-screened candidates, fast turnaround, full compliance, and transparent pricing.

Step 5: Manage Cash Flow

This is the biggest challenge for new temp desks. You pay your temps weekly, but clients often pay on 30 or even 60-day terms. That gap can cripple a new business. Invoice factoring or recruitment finance facilities can bridge this gap. Companies like Sonovate, Bibby Financial Services, and Simplicity specialise in funding for recruitment agencies.

Using AI in Temp Recruitment

AI tools are particularly useful in temp recruitment because of the speed and volume involved. Here are practical applications:

• Candidate matching: AI can match available temps to client requirements in seconds based on skills, location, availability, and compliance status
• Compliance automation: AI-powered document verification can speed up right-to-work checks and flag expiring documents before they cause problems
• Shift filling: When a client calls at 6am needing three warehouse temps for the day shift, AI can automatically identify and notify available candidates from your database
• Market rate analysis: AI tools can scan job boards and industry data to ensure your charge rates and pay rates are competitive

Common Mistakes in Temp Recruitment

• Ignoring compliance: HMRC and the Employment Agency Standards Inspectorate do check. Getting caught without proper right-to-work documentation or KIDs can result in significant fines and losing your licence to operate.
• Not tracking AWR dates: Forgetting about the 12-week mark and suddenly having to absorb the cost of a pay increase destroys your margin.
• Pricing too cheaply to win clients: If your margin is too thin, one sick day or one late payment from a client can wipe out your profit. Price for sustainability, not just competitiveness.
• Neglecting candidate relationships: Temps have choices. If you treat them as disposable, they will go to another agency. Good temp recruiters build genuine relationships with their workers.
• Poor cash flow management: The number one reason temp agencies fail is not lack of business. It is running out of cash because they cannot bridge the gap between paying workers and collecting from clients.

Final Thought

Temp and contract recruitment is one of the most profitable areas of the recruitment industry, but only if you get the fundamentals right. Understand the regulations, set up proper systems, price your margins sensibly, and build genuine relationships with both clients and candidates. The recurring revenue model means that every contractor you place is not just a one-off fee but an ongoing income stream.

Whether you are starting a temp desk from scratch or looking to improve an existing one, the combination of solid compliance knowledge and modern AI tools gives you a significant competitive advantage.
