The Association of Translation Companies is the UK’s trade body for language-service companies, founded 1976, with 245 member companies. Membership certifies the company — not an individual translator. ATC vets financial stability, quality-management systems, client and supplier references, and professional-indemnity insurance, and members commit to an enforceable Code of Professional Conduct. It is recognised at UK government level as the mark of quality-managed language services.

ATC certifies a company; ATA certifies an individual translator. ATC is the UK frame — read by UKVI, the Home Office, HM Passport Office, and UK courts. ATA is the US frame — read by USCIS, US courts, and US universities — and is earned by a sub-20% pass-rate examination in a specific language pair. They answer different receiving authorities. Othello holds standing in both and tells clients which one their engagement actually needs. See ATA-Certified Translation.

The Certification Stamp is awarded to Accredited ATC Members. It carries the member company’s name, membership number, and the year. Applied to a translation, it assures the receiving authority that the work was carried out by a company belonging to a professional industry association and that the translation is a true and accurate reflection of the original. Membership is independently verifiable via the ATC Member Directory — the authority can confirm it.

UK authorities require a certified translation of foreign-language documents — and ATC company-level certification is among the most widely recognised markers of professional standing in the UK market for meeting that requirement. It is not the only acceptable form, but it signals to caseworkers that the firm operates within a regulated professional framework, is insured, and is accountable to an industry body with enforceable standards — which is why it is read without further qualification.

Yes. ATC’s Accredited and Associate memberships are open to language-service companies in the UK and overseas. The credential the receiving UK authority reads is the firm’s company-level standing — its vetting, insurance, and Code-of-Conduct commitment — not its postcode. Othello operates the UK-facing certified-translation engagement under company-level ATC quality-managed discipline, Bangkok-bench-managed with the audit-trail retained Bangkok-side.

Accredited Members pass rigorous background checks on financial and operational viability and quality management, hold professional-indemnity insurance, and gain sole use of the ATC Certification Stamp. Associate Members commit to the Code of Professional Conduct and may upgrade to Accredited on meeting the criteria. The practical distinction: only Accredited members may apply the Certification Stamp to a translation, so for stamp-required UK submissions the Accredited tier is the relevant one.

They share lineage. ATC was one of the original developers of EN 15038, the European translation-services standard that became the precursor to ISO 17100 — the process standard Othello already works to. ATC also founded ATC Certification, a body providing ISO certification worldwide (ISO 17100, ISO 9001, ISO 18587, ISO 27001). ATC membership is the trade-association credential; ISO 17100 / 9001 are the process and quality-management standards. They reinforce each other.

Personal vital records (birth, marriage, divorce, death), immigration documents (for UKVI / Home Office settlement, visa, nationality), academic records (transcripts, diplomas for UK ENIC and admissions), legal records (contracts, court documents, evidence), and corporate / financial filings (Companies House, FCA, cross-border contracts). Each class has its own format-fidelity discipline — vital records preserve stamp and seal placement; legal records preserve clause numbering.

Yes — and it is often necessary. The translation is the language instrument; the apostille (Hague Convention countries) or full legalisation chain (non-Hague, including Thailand) is the diplomatic instrument that authenticates the originating document. Othello manages the Thai Ministry of Foreign Affairs legalisation path and embassy / FCDO authentication where the destination requires it. This is a parallel chain to translation and adds roughly five to ten business days, depending on queue and office hours.

ATC company-level certification sits inside the same bench discipline as Othello’s bilingual technical translation, ESG advisory, and interpretation work. Founded 2020 on US government bilingual contracts — US CDC, US State Department, UN Women, UK PACT — Othello’s founding standard was set against FAR-grade contractor verification, audit-trail discipline, and NDA-from-first-email confidentiality. A client engaging Othello for ATC-certified UK work gets the same editorial bench, the same ISO 17100 process, and the same procurement-grade documentation discipline as any other engagement. The credential differs by destination; the standard does not. Email [email protected] or call +66 02-859-2145.
