Back-Door Hires: How UK Recruitment Agencies Lose Placement Fees (And How to Prevent Them)

A back-door hire is when a client hires a candidate your agency introduced — but does it directly, without paying your fee. The introduction did the work; someone else banked the result. It is one of the most expensive and least-tracked losses in UK recruitment. Specialist recruitment law firm recLAW reports recovering £13.3 million across 3,432 fee disputes over five years — and those are only the cases agencies caught and chose to pursue. This guide explains how back-door hires happen, what "right to represent" and "effective cause" actually mean, and the specific controls — including CV redaction — that stop them.

This guide is general information for UK recruitment agencies, not legal advice. For your specific terms of business and disputes, consult a recruitment solicitor.

What is a back-door hire?

A back-door hire (also called candidate bypass, going direct, or client poaching) is when a client engages a candidate an agency introduced, without going through the agency or paying the agreed placement fee. The agency made the introduction that led to the hire, but is cut out of the result.

It takes a few common forms:

• The client receives the candidate's CV, passes on the role at the time, then hires them directly months later.
• The candidate and client make direct contact after the introduction and arrange the hire between themselves.
• The candidate is introduced for one role and hired into a different one that was never disclosed to the agency.
• A temporary placement converts to permanent without the agency being told, sidestepping the transfer fee.

The common thread: the agency's introduction was the reason the hire happened, but the fee was avoided.

How much do back-door hires cost UK recruitment agencies?

A single back-door hire on a £50,000 salary at a 20% placement fee costs an agency £10,000 in lost revenue. UK permanent placement fees typically run 15–25% of first-year salary, so the loss scales directly with the seniority of the role.

The clearest industry signal of the scale is from recruitment law: recLAW reports £13.3 million recovered across 3,432 fee disputes over five years. Two things matter about that figure. First, it is money agencies got back only because they detected the bypass and pursued it. Second, the recovered amount is a floor, not a ceiling — the true loss is higher, because the hardest part of a back-door hire is that you often never find out it happened.

First-year salary	Fee at 15%	Fee at 20%	Fee at 25%
£30,000	£4,500	£6,000	£7,500
£50,000	£7,500	£10,000	£12,500
£80,000	£12,000	£16,000	£20,000
£120,000	£18,000	£24,000	£30,000

For a small agency, a handful of undetected back-door hires a year can equal a consultant's billing target.

Why do back-door hires happen?

Most are not elaborate schemes. They happen because the introduction created value the agency could not control after the CV left its hands. The recurring causes:

1. The delayed hire. A client "isn't recruiting right now," keeps the CV, and hires the candidate when budget appears — by which point the introduction feels like old news to them.
2. Direct contact. The CV carried the candidate's phone, email, or LinkedIn, so the client reached out directly and the agency never re-entered the conversation.
3. Attribution disputes. The same candidate was introduced by more than one agency, and the client claims a different source — or claims they "already knew" the candidate.
4. Temp-to-perm. A contractor is taken on permanently without the agency being notified, avoiding the agreed transfer fee.

Cause 2 is the one agencies have the most direct control over — and it is where CV redaction does its work.

What is "right to represent" in recruitment?

"Right to represent" is an agency's documented authorisation to put a specific candidate forward to a specific client for a role — the record that establishes the agency as the party that made the introduction. It usually comes from explicit candidate consent to be represented for that opportunity, plus a dated submission to the client.

It matters because fee entitlement turns on who introduced whom, and when. A clear right to represent — candidate consent plus a timestamped introduction — is the evidence that you, not another source, brought the candidate to the table. Without it, a back-door hire becomes your word against the client's.

Can you reclaim a back-door fee? "Effective cause", explained

In UK introduction-fee disputes, the question is usually whether the agency was the "effective cause" of the engagement — whether your introduction is what actually led to the hire. Two things decide it in practice:

• Your terms of business. A watertight agreement defines what counts as an introduction, sets a time window during which a hire is attributable to you (commonly 6–12 months from introduction), and states the fee. Weak or unsigned terms are where most claims fall apart.
• Your evidence. A dated CV submission, written client acknowledgement, and candidate consent are what prove effective cause when a client disputes it.

recLAW's £13.3 million recovered shows these claims are winnable when the paperwork holds. But litigation is slow and expensive, and you can only pursue a back-door hire you actually discover. Prevention is cheaper than recovery — which is why the controls below matter more than the legal recourse.

How do you prevent back-door hires?

You prevent back-door hires with layered controls, not a single fix: tighten your terms, document every introduction, and remove the direct contact details that let a client go around you. Each control closes a different gap.

Control	What it stops	Effort
Watertight terms of business	Attribution and time-window disputes	One-off legal setup
Timestamped, documented introductions	"We never received that CV" / effective-cause disputes	Built into your workflow
CV redaction (remove contact details)	The client contacting the candidate directly	Seconds per CV with the right tool
Regular client/candidate contact	The relationship going cold after introduction	Ongoing

The first two protect you after a dispute starts. CV redaction is the one that stops the most common bypass before it can happen.

How CV redaction stops the bypass

CV redaction (anonymisation) removes a candidate's direct contact details — name, phone, email, LinkedIn, personal URLs — before the CV is sent to a client. The client can evaluate the candidate fully on experience, skills and fit, but has no way to reach them directly. To take it further, they have to come back through you.

That is the entire mechanism, and it is why CV anonymisation is marketed as bypass protection across the category — it is one of the reasons Allsorter, for example, positions redaction around protecting agencies from losing placements to direct hiring. Strip the contact details, and the path of least resistance for the client leads back to the agency.

This is where a CV tool earns its keep. Quibench removes contact details with one click before client submission, alongside formatting the CV into your branded template — and you can start with the free CV redaction tool.

Does CV redaction also help with GDPR?

Yes — the same redaction that protects your fee also supports UK GDPR compliance, which is why it is worth doing as standard. UK GDPR's data-minimisation principle, Article 5(1)(c), requires that personal data is "adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed." For a shortlisting decision, a candidate's phone number and home address are not necessary — so sending an anonymised profile is good data-minimisation practice.

To be clear, this is general good practice, not a specific regulator instruction to anonymise every CV. But it means a single control — redaction before submission — protects the placement fee and reduces your data-protection exposure at the same time.

Common questions

What is a back-door hire? A back-door hire is when a client hires a candidate that a recruitment agency introduced, but does so directly without paying the agency's placement fee. The agency's introduction caused the hire, but the agency is cut out of the result. It is also called candidate bypass, going direct, or client poaching.

How common are back-door hires in UK recruitment? They are common enough to support a specialist legal industry around them. Recruitment law firm recLAW reports recovering £13.3 million across 3,432 fee disputes over five years — and those are only the cases agencies detected and pursued. Because many bypasses are never discovered, the true frequency is higher than recovered-fee data shows.

What does "right to represent" mean? Right to represent is an agency's documented authorisation to put a specific candidate forward to a specific client for a role. It typically combines explicit candidate consent with a dated submission to the client, and it establishes the agency as the party that made the introduction — the basis for the placement fee.

Are back-door hires illegal, and can I claim my fee back? A back-door hire is usually a breach of the agency's terms of business rather than a criminal matter. Whether you can reclaim the fee generally turns on whether you were the "effective cause" of the hire, which depends on your terms of business and your evidence (dated submission, client acknowledgement, candidate consent). recLAW's recovered-fee figures show these claims are winnable, but you should take advice from a recruitment solicitor on your specific case.

How do I prove I introduced a candidate? With a timestamped record: a dated CV submission to the client, written acknowledgement where possible, and documented candidate consent to be represented for that role. A clear, dated trail is what establishes effective cause when a client disputes the introduction.

Does anonymising CVs prevent back-door hires? It prevents the most common route — direct contact. Removing the candidate's name, phone, email and LinkedIn before submission means the client can assess the candidate but cannot contact them directly, so they have to come back through the agency. It does not replace strong terms of business, but it closes the gap that causes the majority of bypasses.

How long after an introduction can a hire still count as mine? That is set by your terms of business, not by law. Many UK agencies specify a window of 6–12 months from the date of introduction during which a hire of that candidate is attributable to the agency. The exact period is whatever your signed terms state, which is why those terms matter.

---

Back-door hires are a control problem, not bad luck. The fee is lost at the moment a client can act on your introduction without you — and the single biggest enabler of that is a CV that arrives with the candidate's contact details on it. Tighten your terms so you can win a dispute, document every introduction so you can prove effective cause, and redact contact details so the dispute rarely needs to happen. The first two protect you after the fact. The third stops the most common bypass before it starts.
