What we do
Our services
What are interpretation and transcription services?
Interpretation and transcription services convert spoken language into another form: interpretation renders live speech orally between two languages in real time, while transcription converts recorded audio or video into accurate written text, both delivered in the UK under ISO 17100 quality control.
What are the main modes of interpretation offered in the UK?
There are five main modes of interpretation offered in the UK: simultaneous, consecutive, whispered (chuchotage), telephone, and video-remote interpreting, each matched to a specific setting such as conferences, business meetings, courtrooms, and NHS appointments.
Which UK settings need professional interpreters?
Professional interpreters are needed in seven main UK settings: Crown and Magistrates’ Courts, NHS trusts, Home Office asylum interviews, ACAS employment tribunals, police station interviews under PACE, corporate boardrooms, and international conferences.
What types of transcription services are available?
There are four main types of transcription services available in the UK: verbatim transcription, intelligent-verbatim transcription, edited transcription, and time-coded transcription, each producing a different output format for legal, medical, academic, and media clients.
How much do interpretation and transcription services cost in the UK?
Interpretation in the UK is priced per hour or per day (£60–£120 per hour for consecutive, £600–£900 per day for conference simultaneous with 4-hour minimums), while transcription is priced per audio minute (£1.20–£3.50 per minute depending on verbatim depth, language, and turnaround).
How fast can interpretation and transcription be delivered?
Interpretation can be delivered same-day via telephone or video remote interpreting for bookings placed before 11:00 GMT, with face-to-face consecutive assignments available London within 4 hours and conference simultaneous requiring 2 weeks’ lead time; transcription is delivered same-day for recordings under 1,000 source words placed before 11:00 GMT, 24–48 hours for legal and academic packs, and on milestones for projects above 10,000 words, all under ISO 17100 quality control.
Spoken language in the United Kingdom moves through two channels: live oral rendering between languages, and the written capture of recorded audio or video. Both sit alongside written translation under the same ISO 17100 quality framework and serve legal, medical, corporate, and public-sector clients across London and the wider UK.
What are interpretation and transcription services?
Interpretation and transcription services convert spoken language into another form: interpretation renders live speech orally between two languages in real time, while transcription converts recorded audio or video into accurate written text, both delivered across the UK under ISO 17100 quality control. The two workflows share linguists, subject-specific glossaries, and quality gates, and together cover every setting from Crown Court hearings to multilingual corporate conferences and podcast production. Interpretation is an oral, real-time discipline; transcription is a written, post-production discipline — yet both demand the same depth of specialist knowledge, preparation, and two-linguist review before final delivery.
Three attributes separate the two services:
- Medium — interpretation is oral output; transcription is written output.
- Timing — interpretation happens live, in the moment; transcription works from recordings at a time of the linguist’s choosing.
- Language pair — interpretation always crosses two languages; transcription stays in the source language unless combined with translation as a separate sequential workflow.
Within interpretation, the mode of delivery determines the setting and the equipment required. Simultaneous interpreting is used for multilingual conferences, EU panels, and large corporate events that rely on ISO 4043 booths and infrared receivers to deliver real-time output to an audience wearing headsets. Consecutive interpreting suits business meetings, depositions, medical consultations, and small legal hearings where the speaker pauses every one to five minutes for the interpreter to render their words. Whispered interpreting — chuchotage — requires no equipment at all and involves the interpreter sitting beside one or two listeners and whispering a live simultaneous rendition directly into their ears. Each mode carries a different pricing structure, lead time, and logistical footprint, so identifying the right mode at the point of booking is essential.
Within transcription, the output type determines how much of the raw audio is preserved. Verbatim transcription captures every word, filler, and non-verbal cue for legal admissibility. Intelligent-verbatim transcription produces a clean, readable record with fillers removed, suited to corporate minutes and media content. Time-coded transcription adds SRT, VTT, or plain-text timestamps for subtitling workflows and legal disclosure packs. All three output types move through the same ISO 17100 two-linguist quality gate before release.
How does interpretation differ from translation?
Interpretation handles spoken language in real time between two parties, while translation converts written source documents into a written target language with time for research, drafting, and multi-stage revision. Interpreters deliver output in seconds; translators deliver output in hours or days. The skill sets overlap in linguistic knowledge but diverge sharply in cognitive technique — interpreting demands simultaneous memory, reformulation, and delivery under pressure, whereas translation prioritises precision and stylistic equivalence across a longer time horizon.
How does transcription differ from translation?
Transcription converts audio into written text in the same language, whereas translation converts text from one language into another; a translated transcript combines both steps sequentially and is priced as two distinct workflows. A Polish witness interview transcribed verbatim in Polish is pure transcription. That same interview delivered as an English written record is transcription plus translation — the transcription workflow runs first to produce a verified source text, which the translation workflow then processes against the same quality gates.
What are the main modes of interpretation offered in the UK?
There are five main modes of interpretation offered in the UK: simultaneous, consecutive, whispered (chuchotage), telephone, and video-remote interpreting, each matched to a specific setting such as conferences, business meetings, courtrooms, and NHS appointments. All five modes are booked through our Professional Interpreter Services in London desk and delivered under ISO 18841 interpreting workflow with ISO 17100 quality controls on briefing and glossary preparation.
The mode-to-venue matrix below maps each interpreting mode to a specific UK setting, price unit, and typical booking window:
| Mode | UK setting | Price unit | Booking window |
|---|---|---|---|
| Simultaneous | International conferences, EU-style panels | £600–£900 per day (pair) | 2–6 weeks |
| Consecutive | Crown Court, ACAS tribunal, Companies House deposition | £60–£120 per hour, 4-hour minimum | 4 hours (London) to 5 days |
| Whispered (chuchotage) | Board meetings, factory audits, defendant in the dock | £90–£140 per hour | 48 hours |
| Telephone (OPI) | NHS 111, Home Office triage, customer service calls | £1.50–£3.00 per minute | Same day, connected in minutes |
| Video remote (VRI) | Zoom hearings, remote GP consultations, cross-border M&A calls | £70–£130 per hour | Same day to 48 hours |
What is simultaneous interpreting and when is it used?
Simultaneous interpreting is the real-time rendering of a speaker’s words into another language with a 2 to 4 second lag, delivered from a soundproof booth with headsets and receivers, and is used at multilingual conferences, EU-style panels, and large corporate events. Two interpreters share the workload in 30-minute shifts to sustain accuracy over full-day programmes.
Equipment required for on-site simultaneous work:
- ISO 4043 soundproof booth for each target language.
- Interpreter console with dual channels and cough button.
- Infrared or radio-frequency transmitters.
- Receiver-and-headset sets for every delegate (one per seat).
- Technician on site for the full duration.
Full specifications, day rates, and equipment hire packages are on our dedicated Simultaneous Interpreting Services for Conferences page.
What is consecutive interpreting and when is it used?
Consecutive interpreting is the mode where the speaker pauses every 1 to 5 minutes for the interpreter to render the segment into the target language, used in business meetings, depositions, medical consultations, and small legal hearings. No equipment is required beyond a notepad; the interpreter takes structured notes and delivers each segment in the target language after the pause.
Consecutive interpreting suits five UK settings in particular:
- Witness testimony in Crown and Magistrates’ Courts.
- Solicitor-client consultations and depositions.
- Consent-critical NHS appointments (oncology, surgery, mental health).
- ACAS employment tribunal hearings.
- Home Office asylum interviews.
Rates, minimum call-outs, and same-day availability are set out on Consecutive Interpreting Services for Meetings.
What is whispered interpreting (chuchotage)?
Whispered interpreting, known as chuchotage, is a form of simultaneous interpreting delivered directly into the ear of one or two listeners without equipment, suited to board meetings and site visits where only a small group needs the target language. In Crown Court, whispered interpreting serves the defendant in the dock while the trial proceeds in English; in corporate settings, it serves a single non-English-speaking director at an English-language board meeting.
What is telephone and video remote interpreting (OPI and VRI)?
Telephone interpreting (OPI) and video remote interpreting (VRI) connect an interpreter to two parties via phone or video link within minutes, delivering on-demand access for NHS 111 calls, Home Office triage, and cross-border business calls without travel time. VRI runs on Zoom, Microsoft Teams, Webex, or a dedicated platform, giving the interpreter sight of the speaker for lip-reading and gesture; OPI is audio only and priced per minute at £1.50–£3.00.
Common use cases:
- NHS 111 clinical triage in Polish, Punjabi, Urdu, Bengali, or Arabic.
- Home Office initial screening interviews in Pashto, Dari, Tigrinya, or Amharic.
- Customer service escalations for banking, insurance, and utilities.
- Cross-border M&A calls between London and continental Europe.
- Remote GP appointments where a face-to-face interpreter is not available.
Platform integration, minimum billing units, and 24/7 access details are on Telephone and Video Remote Interpreting Services.
What is liaison (ad-hoc) interpreting?
Liaison interpreting, also called ad-hoc or bilateral interpreting, is short-turn consecutive work between two parties in informal settings such as trade fairs, factory audits, and one-to-one client visits. The interpreter switches direction sentence by sentence, priced per hour with a 4-hour minimum in London.
What we offer
Which UK settings need professional interpreters?
Professional interpreters are needed in seven main UK settings: Crown and Magistrates’ Courts, NHS trusts, Home Office asylum interviews, ACAS employment tribunals, police station interviews under PACE, corporate boardrooms, and international conferences. Each setting carries its own regulatory framework, credential requirement, and preferred mode.
- Surgical consent conversations.
- Oncology diagnosis and treatment planning.
- Mental Health Act assessments.
- Safeguarding interviews involving children or vulnerable adults.
- End-of-life care planning.
What types of transcription services are available?
There are four main types of transcription services available in the UK: verbatim transcription, intelligent-verbatim transcription, edited transcription, and time-coded transcription, each producing a different output format for legal, medical, academic, and media clients. Every transcript is proofed by a second linguist against the source audio before release, and files are delivered in the format the downstream workflow requires. Full specifications, pricing per audio minute, and turnaround options are on Audio and Video Transcription Services in the UK.
| Transcription type | Output | Downstream use | Price per audio minute |
|---|---|---|---|
| Verbatim | Every word, filler, false start, non-verbal cue | Court exhibits, PACE interviews, academic research | £2.20–£3.50 |
| Intelligent-verbatim | Clean readable text, fillers removed | Board minutes, podcast notes, market research | £1.20–£2.00 |
| Edited | Grammar-corrected, restructured | Published interviews, book manuscripts | £1.80–£2.60 |
| Time-coded | SRT, VTT, plain-text with timestamps | Subtitling, disclosure bundles, evidence | £2.40–£3.80 |
What is verbatim transcription?
Verbatim transcription captures every spoken word including filler words, false starts, and non-verbal cues, producing a legally admissible record for court proceedings, police interviews, and academic qualitative research. “Um,” “er,” repeated words, laughter, and pauses appear in the transcript with speaker labels and, on request, time-codes.
What is intelligent-verbatim transcription?
Intelligent-verbatim transcription removes filler words, repetitions, and false starts while preserving meaning, producing a clean readable transcript for corporate minutes, podcast show notes, and market-research summaries. The speaker’s intent, phrasing, and order are kept intact; only the friction of natural speech is removed.
What is time-coded transcription?
Time-coded transcription embeds timestamps at fixed intervals or at each speaker change, producing output in SRT, VTT, or plain-text formats used for subtitling, legal disclosure bundles, and video evidence exhibits. Downstream mappings:
- SRT — subtitles for YouTube, Vimeo, broadcast delivery.
- VTT — HTML5 video captions, accessibility compliance.
- Plain-text with speaker labels and timecodes — legal disclosure bundles, evidence exhibits, deposition records.
What is translated transcription?
Translated transcription combines two workflows: the source audio is transcribed in the original language, then the transcript is translated into the target language under ISO 17100 two-linguist review, delivering a bilingual document. A Punjabi safeguarding interview transcribed in Punjabi and translated into English for the court file is a typical example.
Pricing
How much do interpretation and transcription services cost in the UK?
Interpretation in the UK is priced per hour or per day (£60–£120 per hour for consecutive, £600–£900 per day for conference simultaneous with 4-hour minimums), while transcription is priced per audio minute (£1.20–£3.50 per minute depending on verbatim depth, language, and turnaround). A verbatim legal transcription of a 60-minute Crown Court recording at £2.80 per minute costs £168; the same 60 minutes as intelligent-verbatim corporate minutes at £1.40 per minute costs £84 — the per-audio-minute unit exposes when verbatim depth doubles the invoice.
| Service | Pricing unit | Rate range | Minimum |
|---|---|---|---|
| Consecutive interpreting (London) | Per hour | £60–£120 | 4 hours |
| Conference simultaneous (per interpreter) | Per day | £600–£900 | Full day |
| Telephone interpreting (OPI) | Per minute | £1.50–£3.00 | 15 minutes |
| Video remote (VRI) | Per hour | £70–£130 | 1 hour |
| Verbatim transcription | Per audio minute | £2.20–£3.50 | None |
| Intelligent-verbatim transcription | Per audio minute | £1.20–£2.00 | None |
| Rush surcharge (under 24 hours) | Percentage uplift | +40–60% | — |
What drives the price of an interpreter booking?
Interpreter booking prices are driven by five factors: language rarity, mode (simultaneous costs more than consecutive), duration and minimum-call-out, equipment (booths, receivers, ISDN lines), and travel or subsistence outside London. A Mandarin consecutive booking in Central London for 4 hours differs in price from a Pashto consecutive booking in Manchester for 8 hours by both language rarity and travel.
What drives the price of a transcription project?
Transcription price per audio minute is driven by six factors:
- Audio quality (background noise, microphone position).
- Number of speakers (single-speaker dictation costs less than 6-speaker roundtable).
- Accent density and dialect variety.
- Verbatim depth (verbatim beats intelligent-verbatim by 40–70%).
- Time-coding requirements (SRT/VTT adds £0.20–£0.60 per minute).
- Turnaround — rush jobs under 24 hours attract a 40–60% premium.
How fast can interpretation and transcription be delivered?
Interpretation is delivered same-day via telephone or video remote interpreting for bookings placed before 11:00 GMT, with face-to-face consecutive assignments available in London within 4 hours and conference simultaneous requiring approximately 2 weeks’ lead time; transcription is delivered same-day for recordings under 60 minutes placed before 11:00 GMT, within 24–48 hours for legal and academic packs, and on agreed milestones for projects above 10 hours of audio, all passing through ISO 17100 quality control before release.
Telephone interpreting (OPI) is the fastest mode: a caller is connected within minutes at any hour of the day, making it the standard channel for NHS 111 triage, Home Office initial assessments, and urgent cross-border business calls where an on-site interpreter is neither practical nor available. Video remote interpreting via Zoom, Teams, Webex, or a dedicated platform can be arranged the same day for most common languages, and because the interpreter has a clear sight line to the speaker it supports lip-reading and gesture cues that purely audio channels cannot provide. Face-to-face consecutive interpreting in London carries a four-hour minimum notice period; outside London that extends to 24 hours to allow for travel. Conference simultaneous interpreting — which requires ISO 4043 booths, infrared receivers, and a paired booth team — needs around two weeks to source the right specialist pair, arrange equipment, and complete the pre-assignment briefing properly.
Transcription turnaround scales with audio length, verbatim depth, and number of speakers. Standard files are returned within 24–48 hours; rush delivery under 24 hours attracts a surcharge of 40–60% on the base rate. All transcripts, regardless of turnaround tier, go through a second-linguist proofing pass against the source audio before the final document is released.
| Service | Lead time | Same-day cut-off |
|---|---|---|
| Telephone interpreting (OPI) | Connected in minutes | 24/7 |
| Video remote interpreting (VRI) | Same day | 11:00 GMT for common languages |
| Consecutive interpreting (London) | 4 hours minimum | 11:00 GMT |
| Consecutive interpreting (rest of UK) | 24 hours | — |
| Conference simultaneous with booth hire | ~2 weeks | — |
| Standard transcription | 24–48 hours | 11:00 GMT for <60 minutes |
| Rush transcription | Under 24 hours | +40–60% surcharge |
How does ISO 17100 quality control apply to spoken-language services?
ISO 17100 quality control applies to spoken-language services through a two-linguist principle: interpreters work in pairs on assignments over 60 minutes with structured briefings and shared glossaries, and transcripts are proofed by a second linguist against the source audio before release — matching the same standard applied to written translation. ISO 17100 formally governs written translation, but its core two-linguist requirement is the most transferable quality mechanism available, and we apply it as the internal quality gate across interpreter briefing, live delivery, and transcript proofing alike.
The rationale is straightforward: a single linguist working alone is the single point of failure for accuracy, terminology consistency, and completeness. A second linguist — whether rotating in a simultaneous booth, monitoring a consecutive session, or proofing a transcript line by line against the audio — catches errors that fatigue, unfamiliar accents, or specialist terminology gaps would otherwise allow through. For legal and public-sector settings where NRPSI-registered interpreters are required for Ministry of Justice court and police assignments, this paired approach also satisfies the procedural expectations of instructing bodies.
The workflow parallels are visible at three checkpoints:
- Preparation — glossaries, style guides, speaker lists, and reference material are shared with both linguists before work begins, so neither enters the assignment cold.
- Delivery — the primary linguist performs the interpretation or transcription; the second linguist observes, reviews notes, or takes over on rotation for simultaneous assignments to maintain consistent output quality across longer sessions.
- Sign-off — a second-linguist review confirms accuracy and completeness against the source audio before the transcript or assignment record is released to the client.
For transcription specifically, the quality gate also covers format integrity: time-coded outputs in SRT or VTT are checked for timestamp accuracy as well as linguistic correctness, and verbatim transcripts are reviewed to confirm that every filler word and non-verbal cue required for legal admissibility has been captured and correctly notated.
What languages are covered for interpretation and transcription in the UK?
Interpretation and transcription services in the UK cover more than 200 languages, spanning all EU official languages, the principal UK community languages, and rare-language pairs that public-sector bodies require for compliance. The breadth of coverage means that a single booking desk handles everything from a French business negotiation in the City to a Tigrinya asylum interview at a Home Office processing centre, without the need to source specialist agencies separately for each pairing.
The ten most frequently requested languages for UK interpretation and transcription assignments are Polish, Punjabi, Urdu, Bengali, Gujarati, Arabic, French, Cantonese and Mandarin Chinese, Portuguese, and Spanish — reflecting both established diaspora communities and international trade flows. Rare and critical-need languages including Amharic, Tigrinya, Pashto, Dari, Somali, Kurdish (Kurmanji and Sorani), and Farsi are covered for NHS, Home Office, and Ministry of Justice contexts where gaps in provision carry serious legal and welfare consequences.
Sign-language interpreting in British Sign Language (BSL) is handled through the same booking desk, as is relay interpreting — the technique used when no single interpreter spans both the source and target language and a third language serves as the pivot. All interpreters working on Ministry of Justice court and police assignments appear on the National Register of Public Service Interpreters (NRPSI), which is the UK register that MoJ and police forces require for those settings. Language availability for remote modes such as telephone and video remote interpreting is broader than for face-to-face assignments, because geography does not constrain which interpreter is deployed.
How do I book interpretation or transcription services?
To book interpretation or transcription services, send the source language, target language, mode, date, and venue for interpreting — or the audio file and desired output format for transcription — receive a written quote within one working hour, confirm by purchase order, and the assigned linguist begins under ISO 17100 workflow. Every booking, regardless of size or urgency, follows the same structured intake so that nothing critical is missing when the linguist sits down to prepare.
Providing the right information at the point of enquiry is the single most effective way to accelerate turnaround and hold down cost. For interpretation, the key inputs are the language pair, the mode (simultaneous, consecutive, whispered, telephone, or video remote), the date, duration, and location, the subject matter, and any known specialist terminology. For transcription, the key inputs are the audio or video file, the number of speakers, the desired output format (verbatim, intelligent-verbatim, or time-coded in SRT or VTT), and the target turnaround. Rush transcription delivered under 24 hours carries a surcharge of 40–60% on the standard per-audio-minute rate, so confirming the true deadline at the outset avoids unnecessary cost.
Interpretation is priced per hour for consecutive assignments — £60–£120 per hour with a four-hour minimum — and per day for conference simultaneous, where rates of £600–£900 reflect the specialist booth skills, paired working, and preparation time involved. Transcription is priced per audio minute, with rates of £1.20–£3.50 scaled by verbatim depth, number of speakers, and turnaround tier. Written quotes itemise every variable so that the final invoice carries no surprises.
Booking steps:
- Send source and target languages, mode, and date/venue (interpreting) or audio file and output format (transcription).
- Receive a written quote within one working hour, including linguist profile and quality gates.
- Confirm by written purchase order and sign the mutual NDA.
- Share reference material — agenda, glossary, prior transcripts, speaker names, and any jurisdiction-specific terminology.
- Assignment proceeds; second-linguist review runs in parallel or post-delivery before release.
- Receive the final deliverable and invoice with the ISO 17100 workflow record attached.
