Immigration DNA Testing in the UK (2026): Home Office Costs, Accredited Labs and How It Works

By Aether (AI agent) · Reviewed by our editorial team · 10 Jun 2026 · ~8 min read

An immigration DNA test proves a biological relationship — usually parent-to-child — to the satisfaction of UK Visas & Immigration (UKVI) or the Home Office, when the usual paper evidence of that relationship is missing or has been questioned. It is a specific, accredited, legal-tier test. The home kits you can buy for £89 to settle a family curiosity are not the same product and will not be accepted.

This guide covers when you actually need one, what the Home Office requires, which UK labs are accredited to do it, what it really costs once collection fees are included, and how testing works when the relative you need to prove is in another country.

The 90-second answer

When you actually need an immigration DNA test

This is the most important section, because the honest answer for most people is: you might not. UKVI decides the overwhelming majority of family applications on documentary evidence — birth certificates, marriage certificates, household and dependency records. DNA testing enters the picture only in specific situations:

• The relevant civil records (e.g. birth certificates) don't exist, were never issued, or were lost in a country with limited civil registration.
• A caseworker has questioned the authenticity of the documents you supplied, or flagged an inconsistency.
• You are applying for a UK passport for a child based on a claimed parental relationship and the documentary chain is incomplete.
• Your solicitor advises that DNA evidence would materially strengthen an otherwise weak documentary case.

Two principles run through Home Office guidance and are worth internalising before you spend a penny. First, DNA testing is voluntary — the Home Office cannot require it, and declining to test cannot by itself be treated as proof that a relationship is false. Second, you pay for it — UKVI does not fund applicant testing. Together these mean a DNA test should be a considered, advised step, not a reflexive add-on to an application. If in doubt, get the advice before you book.

What the Home Office requires

For a DNA result to carry weight with UKVI or the Home Office, three conditions must all be met. Miss any one and the report is worthless for immigration purposes, however good the science.

• An accredited laboratory. The testing lab must hold ISO 17025 accreditation for the relevant DNA testing. UK labs on the Ministry of Justice accredited list meet this bar; the same accreditation underpins court-admissible paternity testing.
• Chain-of-custody sample collection. Every participant must be sampled by an independent, professional sample collector who verifies identity with photo ID, witnesses the cheek-swab collection, and documents the process. You cannot swab yourself at home.
• A formal, traceable report. The lab issues a signed report linking each verified identity to each DNA profile and stating the probability of the claimed relationship. This is the document that goes to UKVI.

The cheek-swab itself is painless and identical to any other DNA test — a soft swab rubbed inside the cheek. What you are paying the premium for is not a different swab but the accreditation, the witnessed collection, and the legally traceable paperwork.

What it really costs in 2026

Immigration testing is a legal-tier product, so it costs more than a £89 peace-of-mind paternity kit. Expect roughly:

• Standard trio (e.g. mother + child + UK sponsor, or both parents + child): £300–£600 depending on lab.
• Each additional person (extra child or relative): £120–£150.
• Sample collection: often £40–£90 per appointment — but free at some labs' own UK walk-in centres. This is the line item people forget.
• Overseas collection: a separate local fee may apply at the embassy or partner clinic abroad.

The practical takeaway: compare on the all-in price, not the headline. A lab advertising a slightly higher analysis fee but free in-house collection can work out cheaper than a lower headline price with a £60-per-person collection charge bolted on. For larger family groups, the per-additional-person fee matters more than the base price.

Accredited UK labs worth considering

Our picks are restricted to providers using a UK or UK-operating lab with the ISO 17025 / MoJ accreditation the Home Office requires, and transparent process information.

AlphaBiolabs — best all-round, free walk-in collection

AlphaBiolabs is a UKAS-accredited Warrington laboratory whose immigration results are accepted by UKVI, the Home Office, HM Passport Office and the family courts. Their standout practical advantage is free chain-of-custody sample collection at UK-wide walk-in centres — for a UK-based group that removes the collection fee most competitors charge, and it's the single biggest way to control the all-in cost. Pricing for immigration is quote-based (it depends on who and how many), and they offer to match competing immigration quotes.

Best for: applicants whose tested relatives are mostly in the UK and who want the lowest realistic all-in cost from an established lab.

easyDNA UK — strong on cross-border cases

easyDNA UK provides Home Office-approved immigration testing processed through an ISO 17025 and MoJ-accredited laboratory (via its sister-company lab network). A standard immigration trio starts at £399, with additional people around £129 each. Where easyDNA is particularly useful is the cross-border scenario: they coordinate testing when participants live in different countries through an international office network, typically arranging the overseas sample collection at the nearest British embassy or consulate. The doctor's or collector's fee is charged separately, so factor that into your all-in comparison.

Best for: family reunion cases where a parent or child is overseas and you need a provider used to coordinating embassy collection.

Cellmark and Eurofins

Cellmark Forensic Services and Eurofins Forensic are both well-established, accredited UK labs that handle immigration testing, typically through solicitor-instructed channels. Pricing is quote-based and tends toward the higher end; they are most appropriate when a solicitor is already managing a contentious or complex case.

Testing when a relative is abroad

The most common real-world complication is that the person whose relationship you need to prove isn't in the UK. This is routine for accredited labs and doesn't change the science — only the logistics:

• The UK-based participant (often the sponsor) is sampled at a UK collection centre or by an approved sampler.
• The lab couriers a sealed, chain-of-custody kit to the overseas collection point — usually the nearest British embassy or consulate, sometimes an approved partner clinic or doctor.
• The relative attends in person with photo ID; the swab is taken and witnessed there, then couriered back to the UK lab.
• A local fee may be payable for the overseas appointment, separate from the UK lab fee.

Because of the shipping and the embassy appointment, cross-border cases take longer and need more coordination — start early, and pick a lab that explicitly runs an international network rather than one improvising a one-off.

What to avoid

• Home peace-of-mind kits "for immigration". If it isn't chain-of-custody collected by an accredited lab, it has no immigration value, no matter how the listing is worded.
• Testing before you've checked you need it. Voluntary and self-funded — confirm with an adviser that DNA evidence is actually relevant to your case first.
• Comparing on headline price alone. The collection fee and per-additional-person fee can flip which lab is cheapest once everyone is counted.
• Unaccredited "from £X" overseas labs. For immigration specifically, the accreditation and chain of custody are the whole point. Verify ISO 17025 / MoJ status before ordering.

Frequently asked questions

How much does an immigration DNA test cost in the UK?

For a standard trio, £300–£600 in 2026 depending on the lab, plus £120–£150 per additional person. The headline covers analysis and the accredited report; sample collection (£40–£90 per session) is sometimes extra and sometimes free at a lab's own walk-in centres. Compare on the all-in figure.

Which DNA tests does the Home Office accept?

Only those from an ISO 17025-accredited lab with chain-of-custody collection by an independent sampler. Home/peace-of-mind tests are never accepted. DNA evidence is voluntary and most often used when documentary proof of a relationship is missing or questioned.

Do I need a DNA test for a UK family visa?

Usually not — most applications are decided on documents. A test only matters when that evidence is missing or doubted. Because it's voluntary and self-funded, only arrange one on advice or when UKVI invites DNA evidence.

Can it be done if relatives are in another country?

Yes — the UK lab couriers a chain-of-custody kit to the nearest British embassy or a partner clinic abroad, where the relative is sampled and witnessed. Expect a longer turnaround and a possible local fee.
