Clinical genetics concierge · London
Private genetic testing in London, interpreted by a clinical geneticist.
Genetic testing done properly — with clinical counselling before and after, results interpreted by a consultant geneticist, and a plan for you and your relatives. Not a mail-order swab.

Counselling first, always
A genetic result changes how you and your relatives think about your health. We start with a conversation, not a swab.
- 02
Clinical genetics, not retail
Interpreted by a consultant clinical geneticist or registered genetic counsellor — not a mail-order lab report.
- 03
Accredited labs only
UKAS-accredited genetics laboratories with results classified to ACMG standards.

The problem
Genetics isn’t a lifestyle choice.
A DNA result changes how you and your relatives think about your health for the rest of your life. It deserves a proper conversation before you decide to test, and a proper conversation once the result comes back.
-
A relative has been diagnosed
A first-degree relative has a pathogenic variant, or a strong pattern of cancer runs in the family. We arrange targeted testing.
-
You’re thinking about a family
Pre-conception carrier screening and counselling, tailored to your background and family history — not a generic panel.
-
A consumer test flagged something
A 23andMe or Ancestry result is not a clinical diagnosis. We arrange formal interpretation and a lab-confirmed test where needed.
The journey
From enquiry to result — counselling at both ends.
One clinical geneticist across pre-test, test and post-test. Total elapsed time is typically four to eight weeks for a panel — longer for whole-genome sequencing.

Interpretation and follow-up
- 01
Before
You tell us why you’re testing
A short, confidential form. Family history, ancestry, any prior results and what you want to understand.
- 02
Before
Pre-test counselling booked
A 45–60 minute session with a consultant clinical geneticist or genetic counsellor before any sample is taken.
- 03
Before
We agree the right test
Single gene, targeted panel, exome or genome — matched to your question, with the implications spelled out.
- 04
On the day
The sample
Usually a small blood draw, occasionally a saliva sample. A few minutes with an experienced clinician.
- 05
On the day
Off to an accredited lab
Your sample goes to a UKAS-accredited genetics laboratory, with sequencing and variant classification to ACMG standards.
- 06
After
Results reviewed
A consultant clinical geneticist reads the report and prepares a personalised interpretation for you.
- 07
After
Post-test counselling
We explain the result, what it means for you and your relatives, and arrange surveillance or cascade testing where indicated.
Typical end-to-end: 4–8 weeks. Whole-genome sequencing: up to 16 weeks.
When to test
Indication-led — not curiosity-led.
These are the reasons people come to us for a proper clinical genetic test — as opposed to a novelty ancestry kit.
-
BRCA testing
Family history of breast, ovarian, prostate or pancreatic cancer, or Ashkenazi Jewish ancestry.
-
Hereditary cancer panels
Lynch syndrome, familial polyposis and broader multi-gene panels where several cancers run in the family.
-
Pre-conception carrier screening
Understand the chance of passing a recessive condition to your children before you try to conceive.
-
Inherited cardiac conditions
Cardiomyopathy, long-QT and channelopathies — especially after a family sudden cardiac event.
-
Pharmacogenomics
How you metabolise specific drugs — useful in psychiatry, oncology and pain medicine.
-
Building a family history
We help you draw a proper three-generation pedigree before deciding whether testing is even indicated.
-
Pre-conception counselling
Consanguinity, known family variants, or a previous affected pregnancy — reviewed by a clinical geneticist.
-
Consumer test result review
Do not act on a 23andMe or Ancestry raw-data result medically. We arrange a lab-confirmed clinical test and proper interpretation.
Test types
The tests we arrange most.
What each option is actually for — and when a smaller, targeted test is the better answer.
-
Single-gene test
Targeted BRCA1/2 or a specific familial variant already identified in a relative.
-
Hereditary cancer panel
Multi-gene panels covering BRCA, Lynch, PALB2, ATM and related cancer-predisposition genes.
-
Cardiovascular panel
Cardiomyopathy, arrhythmia and aortopathy genes — often after a family cardiac event.
-
Carrier screening
Recessive conditions relevant before pregnancy, singly or as an expanded panel.
-
Pharmacogenomics
Metabolism genes affecting antidepressants, opioids, statins and chemotherapy dosing.
-
Whole-exome sequencing
The protein-coding regions — used for undiagnosed inherited disease.
-
Whole-genome sequencing
Coding and non-coding regions — highest coverage, longest turnaround, quoted case by case.
-
Consumer-test review
Formal clinical interpretation of a 23andMe or Ancestry report, with confirmatory testing where needed.
Our vetted London network
A small panel of clinical genetics services, we picked them.
Consultant clinical geneticists and registered genetic counsellors, with UKAS-accredited genetics labs behind them. Not listed publicly — introductions are made privately, once we understand your case.
Selection criteria
How we choose every clinic, geneticist and laboratory in our network.
-
CQC-registered clinics with in-house or partnered clinical genetics
-
UKAS-accredited genetics laboratories, with variants classified to ACMG standards
-
Genetic counsellors registered with the GCRB
-
Consultant clinical geneticists interpreting every report
-
Structured counselling before and after — this is not a mail-order test
What to know before you test
The sample is easy. The implications are not.
A blood draw is one of the safest tests in medicine. It’s the aftermath — for you, your children, your relatives — that deserves the real preparation.
-
Pre-test counselling is not optional
A genetic result has implications for you and for your blood relatives. We insist on a proper conversation before any sample is taken.
-
Insurance and life cover
Under the current UK Code on Genetic Testing and Insurance, insurers do not ask about most predictive genetic tests — but disclosure rules apply for very large life-cover policies. We explain what applies to you.
-
Children and adult-onset conditions
Testing children for adult-onset conditions is generally not done — the child should decide as an adult. We follow UK clinical genetics guidance.
-
Variants of unknown significance
VUS results are common and can cause real anxiety. We explain what a VUS is, and — importantly — what not to do about one.
-
Cascade testing in relatives
A positive result triggers an offer of testing to first-degree relatives. We support that conversation and referral.
-
Direct-to-consumer results
23andMe and Ancestry raw data should not drive medical decisions on their own. We arrange a lab-confirmed clinical test where indicated.
-
Pregnancy and prenatal overlap
Carrier screening, NIPT and prenatal diagnosis overlap — we coordinate with fetal medicine where relevant.
-
Safeguarding and consent
For any test involving a child or a person lacking capacity, consent and safeguarding are handled formally.
-
Data privacy and storage
Ask where your data is stored, for how long, and whether it can be used for research. We confirm this in writing before you consent.
Reading your report
A genetics report can look intimidating. It isn’t.
Whether it’s a single-gene test or a whole-genome sequence, the report follows the same four parts.
A quiet reminder
A variant of unknown significance is not a diagnosis — and often not something to act on.
If you would like us to talk you through the report before your follow-up, just ask.
- 01 Header
Your details and reason for testing
Your details, the family history that prompted testing, and the specific question being asked of the lab.
- 02 Technique
Which panel and how it was sequenced
The genes covered, sequencing method, coverage depth and any limitations — this is why two labs can give slightly different answers.
- 03 Findings
Variants classified to ACMG standards
Each reportable variant is classified — pathogenic, likely pathogenic, variant of unknown significance, likely benign or benign.
- 04 Impression
The clinical meaning: read this first
What the result means for you, what it means for your relatives, and the surveillance or cascade-testing plan.
Recognised by major UK insurers
Predictive genetic testing is often self-funded; some medically indicated diagnostic tests are covered — we confirm with your insurer.
Frequently asked
Everything we get asked about genetic testing.
Quick answers on cost, referral, BRCA, children, insurance, consumer tests and pre-conception screening.
-
What do genetic tests actually look at?
They look at the DNA sequence of specific genes — or, in the case of whole-exome or whole-genome tests, at all of your protein-coding or entire genomic sequence — to find variants that change how those genes work. Reports classify each variant as pathogenic, likely pathogenic, variant of unknown significance, likely benign or benign.
-
How much does private genetic testing cost in London?
Genetic counselling alone is typically £300–£650. A BRCA1/2 test is £400–£900, a hereditary cancer panel £700–£1,400, and whole-genome sequencing is quoted case by case. We confirm firm figures within one working day.
-
Do I need a referral?
Self-referral is the usual private route, provided you agree to pre-test counselling with a consultant clinical geneticist or a registered genetic counsellor. Some tests are only appropriate after that conversation.
-
What does a BRCA result actually mean for my cancer risk?
A pathogenic BRCA1 or BRCA2 variant meaningfully increases lifetime risk of breast, ovarian and some other cancers — but it is a risk, not a certainty. We explain the actual numbers, the surveillance options, and the risk-reducing options in plain language.
-
Can I test my child?
Testing children for adult-onset conditions is generally not offered — the accepted principle is that the child should decide as an adult. Tests for conditions that present in childhood, or where prevention starts in childhood, are handled case by case.
-
Will a genetic test affect my insurance?
Under the current UK Code on Genetic Testing and Insurance, insurers do not ask about the results of most predictive genetic tests. Disclosure rules apply for life cover above very high thresholds, and for a small number of specific tests. We explain what applies before you test.
-
I have a 23andMe or Ancestry report — is that enough?
No. Consumer test raw data should not be used to make medical decisions on its own. We arrange formal clinical review and, where indicated, a confirmatory lab-based test through an accredited genetics laboratory.
-
Should we do carrier screening before trying for a baby?
It is a reasonable option, particularly if there is a family history, consanguinity, or a relevant ancestral background. We explain what the panel covers and — just as importantly — what it does not.
-
Whole-genome sequencing or a targeted panel?
For a specific familial variant, a targeted single-gene test is usually the right answer. For undiagnosed inherited disease, or complex family histories, exome or genome sequencing may be indicated. A clinical geneticist decides — it is not simply "the biggest test wins".
-
When should I see a specialist urgently?
A known pathogenic variant in a close relative, a new personal cancer diagnosis with a strong family history, or a family sudden cardiac death — these warrant urgent referral. We fast-track those cases.
