What Complement Genomics does

Complement Genomics is a UK-based DNA testing laboratory founded in April 2000 and headquartered at the Durham Genome Centre in Lanchester, County Durham. The company operates as a multi-brand genomics services provider, running Geneblitz (molecular biology and clinical-trial services), chXout (non-human/animal and plant DNA testing), DadCheck Gold and DadCheck Silver (legal and consumer paternity testing), ThatDNACompany (value paternity testing), and a set of COVID-19 sub-brands (Fit4Visit, Back 2 Work, Fit 4 School). Core laboratory capabilities — Next Generation Sequencing, Q-PCR, digital PCR, RT-QPCR, and biobanking — are delivered from a single converted 1850s manor-house facility holding UKAS ISO/IEC 17025 accreditation and Ministry of Justice approval to conduct court-directed parentage testing under section 20 of the Family Law Reform Act 1969.

The company serves four primary customer segments. Consumer-facing DNA testing (paternity and relationship testing) is sold through the e-commerce storefronts at unit-priced transaction fees. Employers across manufacturing, food processing, engineering, retail, hospitality, travel, care homes, professional sports clubs, and independent schools buy business COVID-19 testing programmes (Back 2 Work and direct employer contracts). Healthcare providers — GP surgeries, pharmacies, care homes, hospices — and local councils purchase staff and visitor testing. A smaller, higher-value B2B stream provides genotyping, phenotyping, and pharmacogenetics services to contract research organisations and pharmaceutical companies for clinical-trial support, leveraging 18 years of pharmacogenetics expertise.

The revenue model is a mix of transaction-fee unit pricing (RT-QPCR £95 next-day / £150 same-day; rapid antigen £49) for COVID-19 work and one-time testing fees plus professional-services fees for DNA and clinical-trial work. Distribution combines a direct-to-consumer e-commerce motion (branded websites), an enterprise field-sales motion for employer testing in North East England and North Yorkshire, and laboratory-appointment walk-ins at Lanchester. The business is privately held by CEO Louise Allcroft and General Manager Neil Sullivan, with no external funding rounds disclosed and no M&A activity on record. Customer evidence is anchored on healthcare and charity references (Leadgate Surgery, Claypath & University Medical Group, Foundation of Light) plus partnerships with First Cohort International Ltd for sampling logistics.
