Agency Work and Umbrella Companies in the UK: How the Pay Chain Actually Works

A large share of the work that people arrive into in the United Kingdom is not offered directly by the business where the work happens. It comes through a recruitment agency, and increasingly the payroll runs through a third company called an umbrella. This arrangement is entirely legal and extremely common in construction, warehousing, hospitality, food processing, care and IT contracting. It is also the part of the UK labour market where the gap between the headline rate quoted to a worker and the money that reaches their bank account is widest, and where the largest number of avoidable problems begin.

This article explains the structure, what each party is legally required to give you, and the specific points at which agency and umbrella arrangements go wrong. It is written for someone who has not worked in this system before and who has been quoted a rate that sounds good.

Three parties, not two

In a direct job there are two parties: the worker and the employer. In agency work there are at least three.

• The hirer is the business where you actually turn up and do the work — the warehouse, the site, the hotel.
• The agency found you the assignment and has a commercial contract with the hirer. It is paid a margin.
• The umbrella, where one is used, employs you on paper and runs the payroll. It also takes a margin.

The practical consequence is that the business giving you instructions each day is usually not the business that pays you, and the business that pays you is usually not the business that found you the work. When something goes wrong, the first question is always which of the three is responsible for the thing that went wrong. Getting that wrong wastes weeks.

The assignment rate is not your wage

This is the single most important thing to understand about umbrella work, and it is the source of most complaints.

When an umbrella is used, the agency pays the umbrella an assignment rate. That figure is deliberately higher than a normal hourly wage, because it is designed to cover the full cost of employing you, not just your pay. Out of the assignment rate the umbrella deducts employer National Insurance contributions, the apprenticeship levy where it applies, employer pension contributions, holiday pay, and its own margin. What is left becomes your gross pay, and only then are your own income tax, employee National Insurance and pension contributions taken off.

So a quoted rate of, say, twenty pounds an hour through an umbrella is not comparable to twenty pounds an hour in a direct job. It is meaningfully less. None of this is unlawful — the costs are real and somebody has to bear them — but a recruiter who quotes the assignment rate as though it were a wage, and does not explain the difference, has left you with a false picture.

The correct response is not to argue about the principle. It is to ask for the figures in writing before agreeing to anything, and to compare offers on take-home pay rather than on headline rate.

The Key Information Document

Since April 2020, an agency must give a work-seeker a Key Information Document before agreeing terms. This is a legal requirement, not a courtesy, and it exists precisely because of the confusion described above.

The document must set out the type of contract you are being offered, who will pay you, the minimum rate you can expect, how you will be paid, any deductions that will be made from your pay, any fees for goods or services, and a representative example calculation showing an illustrative gross figure and an illustrative take-home figure. Where an umbrella is involved, the document must name it and show the umbrella’s deductions as well as the agency’s.

If you have not been given one, ask. If it is refused, or if what you are handed is a page of marketing with no numbers on it, treat that as the first serious warning sign about the agency rather than as a paperwork nuisance. An agency that will not put its own deduction structure in writing at the start is unlikely to be straightforward about anything later.

The twelve-week rule

Under the Agency Workers Regulations, an agency worker who completes twelve calendar weeks in the same role with the same hirer becomes entitled to equal treatment with a comparable directly employed worker on basic working and employment conditions — pay, working time, rest periods, night work, and annual leave.

Some points that are routinely misunderstood:

• The twelve weeks are counted in calendar weeks in which you work at least one hour, not in hours or in continuous days.
• Certain breaks pause the clock rather than resetting it. Others, including some maternity and sickness absence, count towards it.
• From day one — not week twelve — agency workers are entitled to access the hirer’s collective facilities such as canteens, transport and childcare, and to be informed of internal vacancies at the hirer.
• Moving a worker to a nominally different role in order to reset the clock is a well-known avoidance tactic, and the regulations contain anti-avoidance provisions aimed at exactly that. If the work is substantively the same and the job title changed shortly before week twelve, that is worth raising.

Equal treatment does not extend to occupational sick pay, redundancy pay or most bonus schemes tied to permanent status. It is a floor, not parity in everything.

What an agency cannot do

The conduct rules governing employment agencies are stricter than most work-seekers realise.

An agency cannot charge you a fee for finding you work. Narrow exceptions exist in entertainment and modelling, and they do not apply to warehouse, driving, care or construction work. An agency cannot make your engagement conditional on buying goods or services from it — training, uniform, insurance, transport, accommodation — and it cannot withhold your pay because you did not buy them. It cannot refuse to pay you on the basis that the hirer has not yet paid the agency, and it cannot make payment conditional on producing a signed timesheet if the work can be shown to have been done another way.

Where the sector is agriculture, horticulture, shellfish gathering or food and drink processing and packaging, the labour provider must additionally hold a licence from the Gangmasters and Labour Abuse Authority. That licence can be checked on the GLAA’s public register in under a minute, and doing so is one of the highest-value checks available to anyone being recruited into those industries.

Umbrella companies: the 2026 change

The umbrella sector has been the subject of sustained concern about non-compliance, and the legal architecture around it has changed.

From April 2026, responsibility for accounting for PAYE on payments to workers supplied through umbrella companies moves up the supply chain to the recruitment agency that supplies the worker to the end client — or, where there is no agency, to the end client itself. The practical intention is that the party with the commercial relationship and the assets can no longer treat an umbrella’s failure to pay tax as somebody else’s problem.

For a worker, the significance is straightforward: the agency now has a direct financial reason to care whether the umbrella it puts you through is compliant, which is a meaningful improvement on the previous position. It does not remove the need to check your own payslip. Because the change is being implemented through commencement and transitional provisions, anyone whose assignment straddles the change should confirm in writing who is operating PAYE on their pay.

Schemes that promise unusually high take-home pay

If an umbrella, payroll provider or “contractor solution” promises take-home pay of eighty per cent or more of the assignment rate, or eighty-five, or ninety, the arithmetic does not work under normal PAYE. Something else is happening.

The usual mechanism is that part of the payment is characterised as something other than salary — a loan, an annuity, a capital advance, a grant, a payment from an offshore trust — so that tax is not deducted from it. HMRC does not accept these characterisations. The consequence falls on the worker, not on the promoter: HMRC pursues the individual for the tax that should have been paid, often years later, with interest.

Two defences are available and both are free. HMRC publishes a list of named tax avoidance schemes and promoters, and checking a proposed arrangement against it takes minutes. And the structure itself is a tell — if you are asked to sign a second agreement alongside the employment contract, if part of your money arrives from a different entity than your payslip shows, or if you are told the arrangement is “HMRC approved” or “QC approved”, those are the standard markers. HMRC does not approve schemes.

Checking the entity itself

Both agencies and umbrellas are limited companies, and the public register at Companies House shows when a company was incorporated, who its directors are, whether accounts have been filed, and whether it is subject to a proposal to strike it off. A payroll company incorporated four months ago, with a single director and a registered office at a mail-forwarding address, is not automatically fraudulent — but it is a different proposition from one with a decade of filed accounts, and it is worth knowing which one is about to hold a fortnight of your wages.

A related pattern worth naming is mini umbrella company fraud, in which a workforce is fragmented across a large number of very small companies in order to exploit employment allowances and VAT thresholds. Workers caught in it often find their employer’s name changing every few months for no explained reason. If your payslip issuer keeps changing, ask why in writing.

Anti-scam: how this specific system is exploited

The agency and umbrella structure produces a recognisable family of frauds, distinct from the generic ones.

• Registration, training or compliance fees. No legitimate agency in these sectors charges a work-seeker to be placed. A demand for money before an assignment starts is the clearest single indicator of fraud.
• Fake agencies using a real company’s name. Check the contact domain, and check the company number against Companies House rather than trusting a logo.
• The “your first payslip is delayed” script. Money is requested for an alleged payroll setup, DBS check, insurance policy or equipment deposit, and the assignment never materialises.
• Documents held “for compliance”. No agency needs to retain your original passport or BRP. It may take a copy. Handing over originals creates leverage over you and should be refused.
• Bank details changed by email. Payroll diversion fraud is common. Confirm any change of payment details by phone using a number you already had, never one supplied in the same message.
• Pressure to decide immediately. A real assignment survives you reading the Key Information Document overnight.

Never pay money to obtain work. There is no lawful version of that transaction in these industries.

What to keep

Keep the Key Information Document, the contract with the agency, the separate contract with the umbrella if there is one, every payslip, and your own independent record of the hours you worked and where. Photograph the site sign-in sheet if there is one. The reason is practical rather than legalistic: in a three-party structure, each party’s default response to a complaint is that the problem lies with one of the other two, and the only thing that ends that circle quickly is a worker who can produce dates, hours and figures without having to ask anyone for them.

Official sources worth reading before you sign anything

• Agency workers: your rights (GOV.UK) — Explains the 12-week equal treatment rule and what an agency must tell you.
• Working through an umbrella company (GOV.UK) — Sets out how umbrella pay is built up and which deductions are legitimate.
• Named tax avoidance schemes and promoters (GOV.UK) — HMRC publishes schemes it has identified. Check a proposed arrangement against this list.
• Acas guidance for agency workers — Free, impartial explanation of where an agency worker stands in a dispute.
• Complain about an employment agency (GOV.UK) — Route into the Employment Agency Standards Inspectorate.
• Gangmasters and Labour Abuse Authority — Licensing body for labour providers in agriculture, shellfish and food processing.
• Companies House register — Check that an agency or umbrella actually exists and how long it has existed.

The short version

Compare offers on take-home pay, not on the quoted rate. Demand the Key Information Document before agreeing anything. Count your twelve weeks. Check the licence if the sector needs one and the company number in every case. Treat any promise of unusually high take-home pay as a tax liability being deferred onto you. And never pay to be given work.
