Even Expert English Expires: Nine Years for Controllers

Healthcare regulators give an English certificate two years. One provider in this series gives results for life.

Aviation sits between the two, and it puts a nine year clock on the highest rating it awards.

Key takeaways

• Nine years for a Level 6 expert endorsement, under UK Regulation (EU) 2015/340.
• ORS4 No. 1638 extends all such endorsements to 22 December 2028.
• The extension is automatic, even if the licence does not show it.
• An invalid assessment invalidates an FRTOL and delays licence requests.
• A controller's Level 6 credits across to their radiotelephony licence.

Nine years for expert

The Civil Aviation Authority states it plainly. In accordance with UK Regulation (EU) 2015/340, the validity period for a Level 6, expert, English Language Proficiency endorsement for air traffic controllers is currently set at nine years.

That is a long time by the standards of everything else in this series, and it is still not forever.

The distinction matters. Aviation could have treated its top rating as a permanent statement about a person, in the way an academic award is permanent. It did not. Even at expert level, the endorsement is a demonstration with a shelf life.

That is the same instinct behind the two year windows healthcare regulators use, stretched over four and a half times the period. Only one body in this series publishes a reason for choosing a window at all, and it is a dental regulator rather than an aviation one, covered in why English certificates last two years.

The blanket extension to 2028

Alongside the standing rule sits a live administrative measure worth knowing about.

The CAA has issued ORS4 No. 1638, which extends the validity of all English Language Proficiency endorsements shown on the UK air traffic controller 2015/340 licence until 22 December 2028.

It applies to holders of Level 6 endorsements that were set to expire before 22 December 2028.

So a controller whose endorsement was due to run out in, say, 2027 now holds one valid until the end of 2028 instead. The nine year rule remains the standing position; this sits on top of it as a dated measure.

You do not apply for it

The most practically useful sentence on the page is the one about process, and it removes a piece of admin rather than adding one.

There is no requirement for controllers holding Level 6 endorsements to apply for this extension, as this will be set by default, even if not shown on their licence.

Read the last clause twice. The licence document may still display the original expiry date, and that display is not evidence that the extension has not been applied.

That is unusual, and it is worth stating because the natural response to a licence showing an approaching expiry is to act on it. Here the paper and the position can differ by design.

Against every other validity rule

Setting the aviation number beside the rest of the series shows how wide the range actually is.

Three regimes are visible. Gatekeeping bodies deciding whether you may work next month use two years. Educational awards recording that you reached a level are permanent. Aviation does something neither: a long window that still closes.

We compared the two year and permanent designs, and the different dates each body measures to, in English certificates that expire.

Nine years is long enough to cover most of a career stage and short enough that a controller will meet it more than once. Whether that is calibrated to anything we cannot say, because no reasoning is published.

What lapsing actually costs

The CAA's pilot licensing page carries the consequence in one line, and it reaches further than the endorsement.

An invalid language proficiency assessment invalidates an FRTOL and will delay any subsequent licence request.

A Flight Radiotelephony Operator's Licence is what permits use of the radio. So a lapsed language endorsement does not merely leave a box unticked; it removes the licence that depends on it, and slows down anything else in the queue behind it.

That is a sharper consequence than most of the requirements in this series carry. A healthcare candidate with an expired certificate faces a delayed registration. An aviation professional faces an invalidated operational licence.

One credit that crosses licences

There is one piece of good news for controllers, and it is a rare case of two licensing regimes talking to each other.

UK controller licence holders who hold a current Level 6 endorsement on their Regulation 2015/340 licence are credited with English language proficiency on the issue of their FRTOL.

Two other rows in the same note are worth reading beside it.

The FISO line is the interesting one. It is not that their assessment is rejected; it is that no assessment exists to carry across, and non-UK FISOs are also excluded because their assessment was not conducted through a UK approved centre.

The routes and evidence behind a Level 6 award in the first place are set out in aviation's top English level asks about your childhood, and the all-or-nothing rule governing the assessment itself in the examiner must have no doubt.

What to do with this

• Check your expiry against 22 December 2028, not against the date printed on the licence.
• Do not apply for the extension. It is automatic.
• Treat lapsing as an operational problem, since it invalidates an FRTOL.
• If you are a controller applying for an FRTOL, the credit exists. Use it.
• If you are flight crew, there are no credits. Everybody meets FCL.055.

Nine years is long enough that most people will not think about spoken English again until it is due, which is exactly the risk. Speaking is the skill that fades quietest when unused, and it does not come back by reading. Role play scenarios and a daily speaking partner keep it live, testing your speaking level free tells you whether a gap has opened, and CEFR levels for speaking explains the general scale. ICAO Level 6 rewards adapting to a weaker speaker covers what the top level actually assesses, cabin crew interview questions covers the adjacent role, and Cambridge speaking criteria by level shows how spoken English is marked in detail.

What we could not verify

We did not read UK Regulation (EU) 2015/340. The nine year figure is as the CAA states it.

We did not check the validity periods for Levels 4 and 5. The page addresses Level 6, and we have not assumed the others.

We did not read ORS4 No. 1638 itself. Its effect is as summarised on the CAA page.

We do not know what happens after 22 December 2028. The extension has an end date and the standing rule is described as currently set at nine years.

We did not verify the reason for nine years. None is published.

This is not licensing advice. It is a reading of published CAA pages, both linked below.

How we researched this guide

We went to the controller page expecting a score and found a clock.

That is worth noting as a habit. Every requirement in this series has two halves, the threshold and the window, and the window gets far less attention because it is not the number people ask about. It is also the half that quietly ends applications, which is why we wrote a whole comparison about it earlier in this batch.

Nine years stood out immediately because we had four two year rules already written down. Setting them in one table is what shows that there are three distinct regimes rather than a spectrum: short windows for gatekeeping, permanence for educational awards, and one long-but-closing window in aviation.

The automatic extension we nearly reported as something a controller must do, which would have been wrong in the most annoying direction. The page says it is set by default even if not shown on the licence, and a rule that contradicts the document in a person's hand is exactly the sort of thing worth quoting rather than paraphrasing.

The consequence of lapsing came from the pilot page rather than the controller one. Neither page is complete on its own, and reading both is what produced the line about an invalid assessment invalidating an FRTOL.

Practise speaking, from SpeakShark

SpeakShark is an AI English speaking practice app, and a nine year window creates a specific problem that a two year one does not.

Two years is short enough to stay in view. Nine years is long enough to forget about entirely, and spoken English is the skill that drifts most while nobody is watching it, because reading and listening keep happening naturally and speaking does not.

You talk, the AI answers what you actually said, and you get speaking feedback while the conversation is still running. The free tier gives basic feedback; the detailed pronunciation and grammar breakdown is on Premium.

Being straight about the limits: a free session runs five minutes with four turns, we issue no certificates, and we do not teach radiotelephony phraseology or assess against the ICAO scale.

Start free with three sessions a day and no card. Paid sessions run ten minutes with unlimited turns. Limits are on the pricing page, and how it works walks through a session. Sign up here if your endorsement is closer to expiring than you thought.

We are a speaking improvement tool. We are not an exam preparation provider, and we are not affiliated with Cambridge English, the IELTS partners, Pearson or any exam board. For test format, booking and official practice material, go to the exam body directly. Use SpeakShark to make your spoken English stronger, and use official material to learn the test.
