What is a tracing agent, what can one do, and when do you need one?
A tracing agent is a specialist who finds the current address of a person who has moved, lost touch or cannot be found, for a client with a lawful reason to know it. Tracing agents work from records rather than on foot, deliver an address rather than an opinion, and are used by creditors, solicitors, landlords, executors, process servers and individuals with a legal claim. No licence is needed in the UK, so the marks of a reputable one are ICO registration, a recorded lawful basis for every instruction and a fee charged only when the person is found.
What a tracing agent actually does
The job is narrow on purpose: one person, one current address, one date, one confidence rating. A tracing agent takes the details you hold, cross-references more than 150 sources, registers and records, and has a person check the result rather than trusting a single lookup. What comes back is a dated report giving the person's current registered UK address, rated Confirmed, Probable or Possible according to how strongly the evidence agrees.
"Registered" means the address the records currently place the person at. It is usually where they sleep, though occasionally someone is registered at a partner's or relative's home, which is why the rating exists. Where they are on file, a tracing agent can add a mobile number, an email address or an employer. A good one also tells you plainly when the trail leads abroad or simply ends, and does not charge for saying so.
Who uses tracing agents
- Creditors, from a sole trader with an unpaid invoice to a credit control team, who need a current address before a letter before claim, a court claim or enforcement. See trace a debtor.
- Solicitors and litigants in person who must serve documents at the right address, enforce a judgment or locate a party. See tracing for solicitors.
- Landlords and letting agents whose tenant left owing rent or damage, or cannot be found to settle a deposit. See the landlord's guide to tracing a former tenant.
- Executors and administrators looking for a beneficiary or next of kin. Notices under section 27 of the Trustee Act 1925 protect them from unknown claimants but do nothing to find a known beneficiary who has moved. See finding missing beneficiaries.
- Process servers who want the right address before they attend, rather than after a wasted visit.
- Individuals with a legal claim: a guarantor to pursue, a small claim to issue, maintenance to enforce.
- People reconnecting with a relative or old friend, where the only lawful route is consent: the person is contacted and their address is shared only if they agree. See reconnect with someone.
What a tracing agent can and cannot do
A tracing agent can establish where the records place a person today, rate how confident that conclusion is, put it in a dated report, provide a signed statement for court, and add contact or employer details where they are on file.
A tracing agent cannot, and a reputable one will not:
- guarantee where someone will sleep tonight; the report gives a registered address and a rating, not a promise;
- obtain information by deception, which is an offence under section 170 of the Data Protection Act 2018;
- access anyone's accounts, devices or private messages;
- follow, watch or photograph the person, or question their family and neighbours;
- contact the person, other than in consent-based reconnection cases where contact is the point;
- collect money, negotiate or pass on threats;
- trace someone for a client who will not say why, or whose reason is curiosity or a grudge.
Tracing agents, private investigators and debt collectors
A private investigator does broader work: surveillance, interviews, background enquiries and gathering evidence, often charged by the hour. Use one when you need to know what someone is doing; use a tracing agent when you need to know where they are. Neither is licensed. Provision to license private investigators has been on the statute book since 2001 but has never been brought into force.
A debt collector contacts the debtor and asks for payment, and chasing a consumer credit debt on a lender's behalf is an activity regulated by the Financial Conduct Authority. A tracing agent does none of that. It finds the address and hands it to you, your solicitor or an enforcement agent; the debtor is never contacted and never told who was looking. Trace Bureau finds addresses. It does not collect debts.
How tracing agents are regulated
There is no licence for tracing in the UK, but there is a legal framework with teeth. A tracing agent processes personal data, so it is a data controller under UK GDPR and the Data Protection Act 2018. That means paying the data protection fee and appearing on the Information Commissioner's register, recording a lawful basis for every trace, collecting no more than the purpose needs, keeping data securely and for a limited time, and answering the person traced if they ask what is held about them.
For debt, legal, probate, tenancy and commercial purposes the lawful basis is legitimate interests under Article 6(1)(f), supported by a recorded assessment of why the trace is necessary and why the person's rights do not override it. For personal reconnection the basis is the consent of the person being traced. What a client then does with an address is governed by the Protection from Harassment Act 1997 among other laws. The full picture is on is address tracing legal?
How to choose a tracing agent
The market runs from automated websites to long-established agencies quoting per case. These are the questions worth asking before you instruct anyone.
- When is the money taken? "No find, no fee" is often a refund policy: pay first, argue later. Better is a card saved at instruction and charged only when a result is delivered. How much a tracing agent costs explains the difference.
- What arrives? An address in an email is worth little if it is challenged. Look for a dated report with a confidence rating, and a signed statement available for court.
- Do they ask why? An agent that records your purpose and refuses instructions without one is protecting you as well as the person traced.
- Can you look them up? A UK company on the public companies register, a named operator, a postal address and an ICO registration number on the website.
- What are the turnaround options? Committed times, not "usually a few days".
- What happens on a weak result or a no-find? A Possible result should be flagged as such and priced accordingly, and a no-find should cost nothing.
- How long is your data kept? A stated retention period, not silence.
What a tracing agent costs
Consumer-facing no-find-no-fee traces have typically been advertised at tens of pounds to around a hundred pounds, while law firms and businesses have routinely been quoted £150 to £350 and more through traditional agents. Trace Bureau charges £100 for a Standard trace in 3 to 5 working days, £150 for Express within 48 hours and £195 for Priority within 24 hours, same working day when instructed before noon. Firms instructing ten or more a month pay £85 per trace on a monthly invoice. Nothing is charged unless a current registered address is delivered. See the pricing page.
When you need one
You need a tracing agent when a letter to the last address and a word with mutual contacts have not worked, when a deadline is approaching, when the address will be relied on in court, or when the sum at stake makes a wasted step expensive. Creditors should trace before the letter before claim rather than after judgment, as tracing a debtor before issuing a claim explains. Anyone serving proceedings has a duty to take reasonable steps to find a current address, covered in serving court documents without an address. If you would rather try yourself first, how to find someone's address in the UK sets out the options. When you are ready, instruct a trace online in about five minutes.
Questions
Do tracing agents need a licence in the UK?
No. There is no licence for tracing in the UK. A reputable tracing agent is registered with the ICO as a data controller and records a lawful basis for every instruction under UK GDPR.
Is a tracing agent the same as a debt collector?
No. A tracing agent finds the address. A debt collector contacts the debtor to seek payment, which for consumer credit debts is an activity regulated by the Financial Conduct Authority. Trace Bureau finds addresses and does not collect debts.
Will the person know I am looking for them?
Not in a standard trace. The person is not contacted and is not told who instructed the trace. Consent-based reconnection is the exception, because the person has to be asked.
How long does a tracing agent take?
Standard traces are delivered in 3 to 5 working days, Express within 48 hours and Priority within 24 hours, same working day when instructed before noon.
What does a tracing agent cost?
Trace Bureau charges £100 for a Standard trace, £150 for Express, £195 for Priority and £85 per trace for firms instructing ten or more a month, each charged only when a current registered address is found.
