AnswersWhen they dispute it

The client hired my candidate through the back door. Can I charge?

The short answer

Yes, under your terms. A fee is due only if your agreed terms of business set one for this kind of hire and the hire falls inside the period they name; with no fee clause there is usually nothing to claim. If you supplied the person as a temp, or put them forward for temp work, a fee clause is unenforceable unless the client can choose an extended hire instead1. For a supplied temp, it is also unenforceable if the hire starts after the later of 14 weeks from the first day worked and 8 weeks from the last day worked1.

The numbers

When a temp's hire fee runs out.

14 weeksFrom the first day the temp worked. The later of this and 8 weeks applies.1
8 weeksFrom the last day the temp worked for the client.1
42 daysA gap longer than this between assignments resets the first day.1

What you can add

A £7,560 fee, 71 days late

Say you sent a CV on 12 March 2026 with your terms attached. The client interviewed, declined, then hired the person directly from 6 July 2026, inside your 6-month protection period. Your terms set a fee of 18% of a £42,000 salary. You invoiced on 7 July on 14-day terms, due 21 July 2026. On 30 September it's 71 days late. It went late on 22 July, in the second half of 2026, so the rate is 11.75%5: 8% over the Bank Rate of 3.75%.

£7,560.00The fee: £42,000 × 18%
£172.79Interest: £7,560 × 11.75% ÷ 365 × 71 days4
£70.00Fixed sum (invoices from £1,000 to £9,999.99)6
£7,802.79Owed on 30 September 2026

Then it grows by £2.43 a day until they pay.

The road ahead

Six steps. All free.

  1. Step 1: Work out which case you're in

    Supplied as a temp, then hired: regulation 101 limits your fee. Introduced only, not supplied: your terms must set out the specific time period2 in which you may charge.

    Put forward for temp work, then hired before any assignment: your terms must still offer the client an extended hire instead of the fee1.

    Cost: FreeTime: 2 minutes

  2. Step 2: Read your terms of business

    Find the fee clause. It should say what counts as an introduction (a CV sent, an interview), the protection period, which hires it catches (direct, through a company, as a contractor, through another agency) and how the fee is worked out. No clause, or terms the client didn't receive, and you stop here.

    Cost: FreeTime: 10 minutes

  3. Step 3: Put the dates in order

    Pull the dated email that sent the CV with your terms attached, the client's reply or interview invitation, your system log of the submission and any call notes. Add the client's own confirmation or announcement of the start date.

    It won't make the client agree, but it shows who introduced whom, and when.

    Cost: FreeTime: 30 minutes

  4. Step 4: Check the hire falls inside the period

    Count your protection period from the introduction. For a temp you supplied, the hire must start inside the later of 14 weeks from the first day worked and 8 weeks from the last day worked1, and your terms must have offered the client an extended hire instead of the fee.

    Cost: FreeTime: 10 minutes

  5. Step 5: Invoice once the start date is confirmed

    Send the invoice and the letter below to the director or hiring manager, copied to accounts, once the start is confirmed in writing. Write to the client only: you can't charge the candidate a fee for finding work or stop them working elsewhere3.

    Cost: FreeTime: Same day

  6. Step 6: Still unpaid? Add interest, then chase

    From the day after the due date, add interest4 and the fixed sum6, as in the sum above. Chase on day 7 and day 14, and send a letter before action on day 30. The law fixes none of these days.

    The letter before action gives a company 14 days to reply7, and a sole trader 30 days8.

    Cost: FreeTime: 14 or 30 days

A letter you can copy

Letter sending the introduction fee invoice

Send it once the client has confirmed the start date in writing and your terms cover the hire.

Email it so it is dated, with the invoice attached and accounts copied in. Keep a copy. Keep only the routes your clause names (directly, through another company, as a contractor, through another agency).

When not to bother

When it isn't worth it

  • Your terms didn't reach the client first, or you can't show you made the introduction. Either way the fee is hard to rely on, so ask for a call before you invoice, or have a solicitor who does commercial contracts read what you have.
  • The CV was one in a bulk email and the client already had the candidate. Your introduction didn't bring them together, so ask when the client first heard of the person.
  • The protection period had ended. For a temp, if the hire started after the window in regulation 101 or your terms gave no extended-hire choice, the fee can't be enforced, and the same regulation bars you from asking for it.
  • The fee is small beside what the client is worth to you. A call may keep the client where an invoice would not.
  • The client is in Scotland or Northern Ireland. The court route differs there, and this page covers England and Wales only.

The Wolf's note

The work was real, but the fee comes from the clause. Put the dates in order, the CV sent, the terms attached, the start, and quote the clause number. Then the client has a date to answer, not a mood.
