Home Paternity Test Cost in the UK (2026): What You Actually Pay
Important — information, not legal or medical advice
This guide explains what home paternity testing costs in the UK and how to avoid overpaying. If the result might ever be used legally — family court, Child Maintenance Service, a birth certificate, or immigration — a home test will not work; see legal vs peace-of-mind testing and talk to a family-law solicitor. Read our full disclaimer.
A home paternity test in the UK costs £89–£169 in 2026 for the standard case — one alleged father and one child, results in 3–5 working days. That's the honest range from accredited UK labs. Anything advertised far below it usually isn't cheaper once you read the small print, and anything far above it is paying for speed or extras you may not need.
This guide breaks down exactly what you're paying for, the "from £X" pricing trick to watch for, and a transparent comparison of what the main UK labs charge — so you can buy the right test once, at the right price.
The 90-second answer
If you only read one box
- Typical all-in price: £89–£169 for alleged father + one child, 3–5 working days, from a UKAS-accredited UK lab.
- Cheapest transparent options: around £89 all-in from AlphaBiolabs and easyDNA UK, with no hidden lab fee.
- The "from £X" trap: some listings quote a low price for the kit only, then charge a separate laboratory fee to process it. Check the lab fee is included.
- What pushes the price up: express turnaround (+£70–£150), extra children or alleged fathers (+£40–£90 each), adding the mother (£0–£40, often free).
- Cheap ≠ inaccurate. Any UKAS-accredited lab gives the same >99.99%/0% result. Verify accreditation, not the price tag.
- Home tests aren't legal. For court, CMS, birth certificates or immigration you need a £285–£500 legal test — don't pay for a home test you'll have to redo.

The "from £X" trap, explained
The single most common way people overpay is by chasing a headline price that isn't the real price. Here's the pattern: a listing advertises a paternity test "from £29" or even markets it as "free." What that price actually buys is the collection kit — the swabs and the box. To get a result, you then pay a separate laboratory processing fee, which is where the real cost sits. Add the two together and you're frequently above a transparent £89 all-in test that included everything from the start.
This isn't necessarily a scam — it's a pricing structure — but it's designed to win the price-comparison click, not to be the cheapest total. The defence is simple: before you order, find the words "laboratory fee" and check whether it's included or not included. If a test says the lab fee isn't included, the advertised number is not the price you'll pay.
What actually changes the price
Once you're comparing genuine all-in prices, four things move the number:
- Speed. Standard turnaround (3–5 working days) is the cheapest. Next-day or same-day express analysis adds roughly £70–£150. Worth it only if you genuinely need the result fast — the science is identical.
- Number of people. The base price covers one alleged father and one child. Each additional child or additional alleged father typically adds £40–£90.
- The mother. Including the mother's DNA slightly strengthens the statistics but isn't required for a conclusive result. Some labs include her free; others charge £20–£40.
- Peace-of-mind vs legal. This is the big one. A home test is £89–£169; a legal, court-admissible test is £285–£500 because it includes witnessed chain-of-custody collection and accredited reporting. They are different products — see below.
Cheap doesn't mean inaccurate — but unaccredited does
It's natural to assume an £89 test must be worse than a £200 one. For the actual paternity result, that's not true. Every UKAS-accredited UK lab analyses 20–25 STR markers and returns the same kind of result: a probability of paternity above 99.99% for an inclusion, or 0% for an exclusion. The marker science is mature and standardised.
What you should never compromise on is accreditation. A test is only as good as the lab behind it, and the mark that matters in the UK is UKAS accreditation to ISO 17025. The NHS itself advises using a government-accredited testing laboratory. So the right filter isn't "is it cheap?" — it's "is it UKAS-accredited?" An £89 accredited test beats a £150 unaccredited one every time. Verify the accreditation, then optimise for price.
When the cheap home test is a false economy
The most expensive mistake in paternity testing isn't paying too much — it's buying the wrong product. A home test cannot be used for anything legal. If you take a £89 home test and later need the result for the Child Maintenance Service, a family court, a birth-certificate change, or an immigration application, none of those will accept it, and you'll pay £285–£500 again for a proper legal test. You'll have spent more, not less.
So before you optimise for the lowest price, ask one question: is there any realistic chance this result ends up in front of an official body? If yes, skip the home test entirely and read our guide to legal vs peace-of-mind DNA testing. If it's purely for your own knowledge, the £89 home test is exactly the right, and cheapest, tool.

Frequently asked questions
How much does a home paternity test cost in the UK?
£89–£169 in 2026 for alleged father plus one child, 3–5 working days, from an accredited UK lab. The cheapest transparent all-in prices are around £89 (AlphaBiolabs, easyDNA). Express adds £70–£150; extra participants add £40–£90 each.
Why are some paternity tests advertised "from £" so cheap?
Because the headline often covers the kit only, with the laboratory fee charged separately. The combined total can exceed a transparent £89 all-in test. Check the lab fee is included.
Is a cheap home paternity test accurate?
Yes, provided the lab is UKAS-accredited. An accredited £89 test gives the same >99.99%/0% result as a pricier one. Verify accreditation, not price.
Will a home test hold up for court or the CMS?
No. Home tests aren't legally admissible. For court, CMS, birth certificates or immigration you need a legal, MoJ-accredited chain-of-custody test (£285–£500). Order that from the start if there's any legal possibility.
Do I need to test the mother?
No — a father-and-child duo gives a conclusive result. The mother adds slight statistical power and is often free, but she is never mandatory.
