How to Find Someone's Address in the UK, Lawfully

Updated 6 September 2026 by K3K Investigations

Finding where someone lives in the UK is possible, lawful and routine when there is a legitimate reason: a debt to recover, papers to serve, a beneficiary to pay, a relative or friend to reach. It is unlawful and refused when the reason is to turn up at the door of someone who does not want you there. This guide sets out the public sources that genuinely reveal addresses, the ones people wrongly assume do, the law that governs the search, and what a professional address trace costs and delivers.

The first question any investigator asks is not "what is their name?" but "why do you need the address?", and the honest answer decides everything that follows. Keep that in mind as you read: every route below is lawful for a legitimate purpose and none of them is for anything else.

Public records that can reveal an address

The open electoral register. Every council publishes an edited version of the electoral roll that directory sites such as 192.com aggregate. It only lists people who did not opt out, and a large share do, so a miss proves nothing. A hit gives a current or recent address and the names of other adults at it.
Companies House. Directors and people with significant control appear on the free register with a correspondence address, which is often a registered office or an accountant rather than a home, and a month and year of birth that tells apart two people of the same name. Older filings sometimes carry a residential address that was later replaced.
HM Land Registry. For a few pounds the title register for any property in England and Wales names the registered owner and an address for service. It tells you who owns a property, which is not always who lives in it, and it works in reverse: a name search across registered titles is a paid service that reveals property a person owns.
The Register of Judgments, Orders and Fines. County court judgments are public and searchable for a small fee, with the defendant's name and the address the judgment was entered against. For debtor traces this is often the freshest address on record.
Probate records, planning applications and licensing registers all name individuals with addresses in the ordinary course of public administration, and are searched routinely in tracing work.
Social media, indirectly. Few people post their address, but people post photographs of the front door, the street, the view from the window, the gym, the school run and the local pub, and open-source investigators read those clues methodically.

The sources that will not give you an address

The DVLA, HMRC, the Department for Work and Pensions, the NHS, banks, utilities, mobile networks and the police do not release addresses to members of the public, and any website claiming to search them is either selling you the open electoral register or lying. Two lawful exceptions matter. The DVLA will release a vehicle keeper's details to someone who can show reasonable cause, such as pursuing the driver responsible for damage, through its formal application process. And in family proceedings a court can require government departments to disclose a party's whereabouts, a route that runs through your solicitor rather than an investigator.

Anyone who offers to obtain an address by ringing a utility company pretending to be the account holder is describing an offence under section 170 of the Data Protection Act 2018, and evidence obtained that way is worthless. It is also a reliable way to spot an agency you should not hire.

The reasons that justify a professional trace

Tracing agents process personal data under UK GDPR on the basis of a legitimate interest or a legal claim, and that basis has to be real. In practice the instructions we accept look like this: a debtor to be located before enforcement, which our guide on finding someone who owes you money covers in detail; a respondent or witness to be served with court papers, the subject of our guide to process serving; a former tenant who left owing rent or with a deposit dispute unresolved; a beneficiary an executor must pay; a third party to a motor accident; a relative or old friend you have lost touch with, where contact is made through us rather than by handing over the address.

The instructions we refuse look like this: an ex-partner who ended contact, anyone protected by a restraining order or non-molestation order, a person who blocked the enquirer, or an enquirer who cannot give a straight account of why. We ask, we check, and we decline. It is the part of the job that keeps the rest of it lawful, and it is why an address from a professional agency can be relied on in court while an address from a stranger on a forum cannot.

What a professional address trace involves

At K3K an address trace layers three things the public cannot access on the public records above: licensed data with dates of birth and address histories that links a person through every move they have made, open-source research run at depth on our own in-house OSINT platform, and where the paper trail thins, discreet field enquiries. The output is a confirmed current address, not a list of possibles: we say how we know, with a confidence rating and the evidence behind it, because an address you serve papers at has to be right. Our guide on how investigators find people explains the method in more depth.

Address traces are quoted as a fixed fee, typically £150 to £500, agreed in writing before any work starts, with no-trace-no-fee terms on suitable cases. Most conclude within a few days. Give us the full name, an approximate age or date of birth, a last known address and anything else you hold, and the trail is usually short.

Frequently asked questions

Can a private investigator find someone's address from just a name?

Often, provided there is something to anchor the name: an approximate age, a last known area, a former employer or a linked relative. A common name with nothing else is the one starting point that can defeat a trace, and we say so at the free consultation rather than taking a fee to discover it.

Is it legal to find out where someone lives in the UK?

Yes, for a legitimate purpose and by lawful means: public records, licensed data processed under UK GDPR, open-source research and enquiries. It is unlawful to obtain an address by deception, by accessing accounts or systems without authority, or in order to harass or stalk someone. Tracing agents screen every instruction for exactly that reason.

Can I find out who lives at an address?

Partly. The open electoral register lists the adults at an address who did not opt out, and the Land Registry names the owner. For a confirmed answer, such as for a landlord, an insurer or a solicitor, a professional occupancy check combines those records with enquiries and is quoted fixed.

Can you find the address of someone who has blocked me?

No. Someone who has blocked you has told you they do not want contact, and tracing them would be the beginning of harassment, not the end of a search. We decline these instructions and so does every reputable agency.

How much does an address trace cost?

Typically a fixed fee between £150 and £500 depending on how cold the trail is, agreed in writing first, with no-trace-no-fee terms on suitable cases. Overseas traces are quoted individually.
