AWR 12-Week Rule Explained

What are the Agency Workers Regulations (AWR)?

The Agency Workers Regulations 2010 (SI 2010/93) give temporary agency workers in Great Britain the right to the same basic working and employment conditions as someone the hirer recruited directly — once they've worked in the same role, for the same hirer, for long enough to qualify. The regulations implement the EU Temporary Agency Work Directive into UK law, and Northern Ireland has its own, equivalent regulations.

For a UK recruitment agency, AWR sits alongside IR35 and general employment law as one of the statutory obligations you carry on behalf of every worker you place — but it answers a different question to IR35. IR35 asks how a worker should be taxed. AWR asks whether they're being treated the same as a directly-recruited employee doing the same job. They are unrelated regimes that happen to apply to the same population of temporary workers, which is why they get confused.

Who counts as an "agency worker" under AWR

Broadly, someone counts as an agency worker under AWR if they:

• have a contract with a temporary work agency (which can be a contract of employment or another kind of contract), and
• are supplied by that agency to work temporarily for, and under the supervision and direction of, a hirer.

That covers most PAYE and umbrella-company temps an agency places. It does not cover a genuinely self-employed contractor who isn't supervised and directed by the hirer in the way an agency worker is — see the official guidance for the exact boundary before you rely on this for a specific case: gov.uk — Your rights as an agency worker.

Day-one rights vs rights after 12 weeks

AWR splits an agency worker's rights into two tiers:

• From day one, an agency worker is entitled to access the hirer's collective facilities and amenities (things like a staff canteen, childcare provision or transport services) on the same terms as a comparable direct employee, and to be told about relevant job vacancies with the hirer.
• After the 12-week qualifying period, they become entitled to the same basic working and employment conditions — including pay — as if the hirer had recruited them directly for the same role.

The 12-week qualifying period, explained

How the 12 weeks is counted

The clock runs on calendar weeks in the same role, with the same hirer — not weeks worked, and not a rolling total across different assignments with different hirers. A week counts even if the worker didn't work every day of it, as long as the assignment was ongoing.

What breaks or pauses the clock

Some breaks between assignments pause the clock rather than resetting it (so the worker keeps the weeks they've already banked), and others reset it to zero. Whether a particular gap pauses, resets, or has no effect at all depends on its length and reason — the current gov.uk guidance sets out the specific rules, and they're detailed enough that they're worth checking against the live page for any specific case: gov.uk — Your rights as an agency worker.

This is exactly the kind of thing that's easy to get wrong on a spreadsheet: a worker moves to a materially different role with the same hirer, or has a short gap for illness, and the count either should or shouldn't reset depending on the specifics.

What changes once a worker qualifies

Equal treatment on basic pay

Once qualified, an agency worker is entitled to at least the same basic pay they'd have received if the hirer had recruited them directly into the same role, on the same day. That's pay for the job — not every element of a directly-employed remuneration package (some benefits, like occupational sick pay schemes or pension contributions beyond the statutory minimum, aren't covered by AWR pay parity).

Equal treatment on working time, rest breaks, annual leave

Alongside pay, a qualified agency worker is entitled to equal treatment on the basic working and employment conditions that would have applied had they been recruited directly — including working time, night work, rest periods and rest breaks, and annual leave.

Agency vs hirer: who's responsible for what

In practice, both parties carry obligations, and they depend on each other's information:

• The hirer must tell the agency what pay and basic working conditions apply to a comparable directly-recruited employee, so the agency can apply them correctly once a worker qualifies.
• The agency is responsible for actually paying the worker in line with that information once the 12-week qualifying period is reached, and for tracking when each assignment crosses that threshold in the first place.

If the hirer gives the agency inaccurate information, liability can fall on the hirer rather than the agency — but the agency still needs to be the one asking the question and acting on the answer.

The compliance risk of getting AWR tracking wrong

The practical risk is almost always about timing, not disagreement over the rule itself: missing the point at which a specific assignment crosses 12 weeks, and continuing to pay the pre-qualification rate past that date. Multiply a missed uplift by every week it goes uncaught, and by however many assignments are running the same way, and a manual spreadsheet-and-reminder process is genuinely hard to keep accurate at any scale.

How Templio tracks AWR status automatically

Templio counts the AWR week for every active contract from the timesheets actually submitted, flags an assignment as it approaches the 12-week threshold, and records the IR35 status and AWR position on the contract itself — so the question "is this assignment still inside its 12 weeks?" has an answer you don't have to reconstruct from a spreadsheet. It sits alongside the rest of the compliance record: document expiry, IR35 status determination statements, and umbrella due-diligence, on the same pricing, with no separate compliance module to buy.

FAQs

What is the Agency Workers Regulations 2010? A UK statutory instrument (SI 2010/93) giving agency workers the right to equal treatment with directly-recruited employees on basic pay and working conditions after a 12-week qualifying period in the same role with the same hirer, plus certain rights from day one.

What counts towards the 12-week qualifying period? Calendar weeks spent in the same role with the same hirer, whether or not every day of the week was worked. It's specific to that role-and-hirer combination, not a running total across different placements.

Do agency workers get bank holiday pay under AWR? Annual leave and rest entitlements are part of the equal-treatment package that applies once a worker qualifies after 12 weeks — check the live gov.uk guidance for how it applies to a specific bank holiday and assignment pattern, since the detail depends on the hirer's own arrangements for a comparable direct employee.

Do agency workers get sick pay under AWR? Statutory Sick Pay eligibility is a separate, general employment-law question, not an AWR pay-parity right — occupational (enhanced) sick pay schemes are typically outside what AWR requires an agency to match. Don't assume parity here without checking the specific scheme.

What's the difference between AWR and IR35? They're unrelated regimes. AWR is about equal treatment on pay and working conditions after 12 weeks with the same hirer. IR35 (off-payroll working) is about how a contractor's engagement is taxed. A worker can be affected by one, both, or neither — see our PAYE vs umbrella company guide for how engagement models interact with both.

Does AWR apply to umbrella company workers? Umbrella company employees who are supplied to and supervised by a hirer through an agency arrangement are generally within scope in the same way as other agency workers — the umbrella is their employer, but the AWR question turns on the agency-supply-and-supervision relationship with the hirer, not on who runs their payroll.

What notice period applies under AWR? AWR itself doesn't set assignment notice periods — that's a matter for the contract between the agency and the worker (and, where relevant, the Conduct of Employment Agencies and Employment Businesses Regulations 2003). Check the specific contract rather than assuming AWR governs it.

Does AWR apply in Northern Ireland? Great Britain's AWR (SI 2010/93) doesn't itself extend to Northern Ireland, which has its own, equivalent agency worker regulations. Treat GB and NI as two separate (if closely aligned) legal regimes rather than one UK-wide rule.
