When you need an interpreter, not a translator — and how to arrange one that holds up

Two things go wrong before anybody has spoken: somebody asks a translation agency for a "translator" for Tuesday's appointment and is quoted per word, while somebody else brings their daughter because her English is good. The first takes a sentence to fix; the second ends up in a case file.

Translation is priced by the word; interpreting is priced by time

A translator works on paper, with time to check and revise; an interpreter renders live speech, or sign, with no second pass and no delete key. They are separately trained and separately qualified. A certified translation gets your birth certificate accepted. Interpreting gets you understood while somebody asks you questions, and it is charged by time, with a minimum booking and travel on top — so ask for a quote on the appointment's length, place and kind of setting, not on the page count.

Consecutive doubles the clock; simultaneous needs two people

In consecutive interpreting you speak, stop, and the interpreter speaks. It is the accurate mode, takes roughly twice as long, and is how nearly every one-to-one setting works: GP appointments, solicitor meetings, police interviews, a witness giving evidence. Simultaneous interpreting happens while you are still talking, and it is cognitively brutal: conference work is staffed in pairs who swap every twenty or thirty minutes, so one interpreter booked for a full day buys a good morning and a poor afternoon. Say which mode you need when you book; the price follows from it.

A relative is not a neutral party

An untrained bilingual relative does three things without meaning to: they summarise, they soften, and they answer on your behalf. In a consultation that is how a symptom disappears; in a legal setting it is how the record comes to contain something you never said. There is also what you cannot say in front of them: domestic abuse, immigration status, debt, sexual health, mental health, a diagnosis you have told nobody — the person interpreting may be the reason you are there. Children should never interpret, in any setting, for anyone.

In the NHS, get it into your record

NHS England's guidance for commissioners on interpreting and translation in primary care is direct: use a professional interpreter rather than family, friends or untrained bilingual staff, children should not interpret, and the service comes at no cost to the patient. It is guidance to the bodies that buy primary care rather than a right you enforce yourself, but you are asking for what the system already expects to provide. It is England's guidance; Wales, Scotland and Northern Ireland arrange this themselves.

Register your language and your need for an interpreter with your GP practice when you join, so it sits in your record rather than one receptionist's memory, and ask for a double appointment.

With courts and the Home Office, ask on the form

In England and Wales, HM Courts and Tribunals Service arranges and pays for interpreters in defined circumstances; Scotland and Northern Ireland have their own court services and arrangements. A criminal defendant is provided for. In civil cases provision is guaranteed for possession and committal, and in family cases involving children, domestic violence or forced marriage.

Outside those categories it turns on your means as much as your case type. The gov.uk guidance sets the test: you cannot afford an interpreter yourself, you do not qualify for legal aid, and you have no friend or relative the judge is willing to approve. An approved relative is therefore sometimes the arrangement the court expects rather than one it forbids — which does not make it wise. Bringing your own interpreter needs the judge's permission beforehand. Ask on the appeal or claim form, and get the answer in writing.

At an asylum or protection interview the Home Office arranges and pays for an interpreter, who should confirm at the start that your language and variety are right. Other Home Office appointments carry no such guarantee, so ask in advance, and give your dialect as early as the paperwork allows. If you cannot follow the interpreter, or something is rendered wrongly, say so in the room and ask for it written down. A mismatch raised at the time is a correction; found in a transcript a year later, it is a credibility problem.

Check the register, not the agency's homepage

For public-service work the reference point is the National Register of Public Service Interpreters, which covers the whole UK. Searching it is free, and it tells you whether a named individual is registered, in which languages and at what status. Registration rests on a Level 6 diploma and assessed experience, and registrants are bound by a code of conduct with a complaints route — the part that matters on the day something goes wrong.

Booking through an agency, ask for the name and registration number beforehand. Contracts are re-tendered and change hands, so "we work with the Ministry of Justice" tells you about the company, not the person beside you. For prisons and police stations, start early: clearance alone takes weeks.

Accuracy is built before the appointment, not during it

Interpreters prepare, and what you send is what they have.

• The agenda, who is attending and in what role, and anything to be read aloud.
• Clinical or technical terms, acronyms, and company and place names.
• The country and the variety, not just "Arabic": Modern Standard is no substitute for a village, a trade or a symptom.
• Whether you want a male or a female interpreter, and whether it is in person, video or by phone — phone loses everything visual.

How to talk while somebody is interpreting

• Speak to the person, not the interpreter: "Are you taking this medication?", not "ask him whether he takes it".
• One complete idea, then stop. Half a sentence cannot be rendered.
• Drop idiom and jokes, and treat nothing as off the record: the aside gets interpreted too.
• Slow down for numbers, dates, names and addresses, and spell names out.
• If the interpreter asks you to repeat or clarify, that is competence, not failure.
• Break every hour, and do not ask them to fill in a form, witness a signature or give an opinion. They interpret, and nothing else.

The costliest mistake is not a weak interpreter but no interpreter. Where the interpreter was yours to arrange, an appointment that cannot go ahead costs you the delay and whatever you have already paid. Interpreters in the less common languages are booked weeks ahead, so book on the day you learn the date.
