Where can I get a legal DNA test in the UK

by | Jul 3, 2026 | Legal & Immigration

If you’re wondering “where can I get a legal DNA test in the UK?”, it’s important to choose a provider that offers testing that is legally admissible and carried out under a secure chain of custody. Not every DNA testing company offers legally admissible testing, and choosing the wrong provider could mean your results aren’t accepted by the courts or other authorities. Fortunately, NorthGene™ provides legal DNA testing across the UK through our UKAS accredited, Ministry of Justice approved laboratory and nationwide sample collection network, making it straightforward to arrange legally admissible testing wherever you are. In this blog, we’ll explain where you can get a legal DNA test and what to look for when choosing a provider….

What makes a DNA test legally admissible?

A legal DNA test must be completed in accordance with strict legal requirements, including accredited laboratory testing, witnessed sample collection and a documented chain of custody. Unlike a peace of mind DNA test, every stage of the process is independently verified to ensure the results can be relied upon in legal proceedings.

Legal DNA testing is commonly used for:

  • Family court
  • Child arrangement and parental responsibility cases
  • Immigration applications
  • Probate and inheritance matters

Why does the testing laboratory matter?

When instructing a legal or court-ordered DNA test, transparency is essential. Solicitors, family lawyers and the courts need to know exactly where DNA samples are tested and stored to ensure the integrity of the evidence.

However, many DNA testing providers act as ‘middlemen’, outsourcing testing to third-party laboratories or even sending samples overseas.

At NorthGene™, every legal DNA test is processed and stored in our own UK Ministry of Justice approved and UKAS accredited laboratory. From case registration and sample collection to testing, analysis and reporting, every stage is overseen by our experienced UK-based team. This provides complete accountability and confidence that every result is produced to the highest scientific and legal standards. Because every stage of the process is managed in-house, we can deliver accurate, legally admissible results quickly, without relying on third-party laboratories.

What accreditations should a legal DNA testing provider have?

Legal DNA testing providers must be accredited to UKAS ISO 17025, demonstrating that they meet recognised standards for testing competence and quality. Additionally, providers carrying out court-directed testing must also appear on the Ministry of Justice’s approved list of DNA testing providers.

NorthGene™ holds both essential accreditations, ensuring every legal DNA test meets the strict standards required for court admissibility. You can find out more about our accreditations here.

Can I use a peace of mind DNA test instead?

No. If a DNA test is required for legal purposes, a peace of mind DNA test cannot be used. Legal DNA testing must follow a strict chain of custody, including:

  • Independent third-party sample collection
  • Identity verification
  • Secure sample handling
  • Full documentation throughout the entire process

As peace of mind tests do not include these safeguards, their results cannot be relied on in court or for other official proceedings. This is because there is no guarantee that the samples have been provided by the intended participants.

Where can I get a legal DNA test in the UK?

At NorthGene™, we operate a nationwide network of fully trained, DBS-checked, independent third-party sample collectors.

Once a case has been registered, a local collector will be in touch with the participants within 24 hours to arrange an appointment at a time and place that is convenient. Sample collection can usually take place at your home, workplace, solicitor’s office or another preferred location where the participant feels comfortable.

Following collection, samples are securely returned to our UK laboratory in tamper-evident packaging, where they are analysed by our expert team.
