How to renew a UK drone Operator ID: steps, fee and labels

To renew a UK Operator ID, sign in to the CAA's My registration service with your date of birth and access to the email account you registered with, check your details, and pay the £12.34 fee. An Operator ID is valid for one year.

The part that needs planning is the lapse nobody notices. An Operator ID label shows a number and nothing else, so an aircraft flown under a registration that expired last week looks exactly like one flown under a current one. A crew can mobilise on a lapsed registration without anyone deciding to.

The Operator ID identifies the person or organisation responsible for the aircraft. It isn't permission to fly. The person at the controls needs a Flyer ID in most cases, and that has its own expiry date. An operational authorisation from the CAA, or a flight permission from an airport, doesn't replace the Operator ID either.

How to renew, step by step

1. Sign in to My registration from the CAA's renew and manage your registration page, with your date of birth and the email account you used when you registered.
2. Check that your registration details are still correct. The CAA expects them to be kept up to date all year, not only at renewal, so this is the moment to catch anything that drifted.
3. Pay the £12.34 fee. Your Operator ID is then valid for another year.
4. Write down the new expiry date.

The CAA's pages don't say how early renewal opens or whether a reminder email will arrive, so don't count on a reminder. Give the date to one role, usually the accountable manager or the ops lead who sends crews out, and put it in that person's calendar a few weeks early.

The Flyer ID is the other half. It belongs to the person flying, it's free, and it lasts five years. You renew it by taking the theory test again. A team that tracks only the Operator ID can find its pilots' Flyer IDs lapsing on dates nobody wrote down, so put both on the same list. When a new pilot joins, add their Flyer ID and its expiry to that list on their first day, not at their first audit.

A renewal-day checklist for a company

Someone renewing for one drone can stop after the steps above. A company has more to check, because one Operator ID covers every aircraft it's responsible for, and one lapse grounds all of them at once.

• The accountable manager. An organisation registers through a named accountable manager. The CAA lets you change that person at any time, and their details must always be up to date. If the person named on the account has left, fix that before anything else.
• The email address. Sign-in runs through the email on the account. It should be an inbox the organisation controls and someone actually reads, not the personal address of whoever set it up.
• New aircraft. The Operator ID has to be displayed on every aircraft it covers, readable without tools. Check the airframes bought since the last renewal first.
• Your own ID, and your contractors'. The CAA's check service tells you whether a person or organisation holds a valid Operator ID or Flyer ID. You need the ID and the holder's name, or the accountable manager's name for an organisation. Run your own through it once the renewal is done, and run every subcontractor's before they fly for you.

Where company registrations go wrong

Putting the accountable manager's Flyer ID on the organisation account. An organisation's registration can't hold a Flyer ID. If the accountable manager also flies, they need their own Flyer ID, registered with a different email address.

Losing the email account the registration runs through. Renewal needs access to the email you registered with. If nobody can get into it any more, contact the CAA's drone and model aircraft registration team well before the expiry date: drone.registration@caa.co.uk or 0330 022 9930, Monday to Friday, 8:30am to 4:30pm.

Writing the Remote ID private key on the aircraft. Your Remote ID number is in My registration. One number covers every aircraft you operate, and it's similar to your Operator ID but not the same. The last three characters are a private key. The aircraft asks for the full number when you set it up, but the CAA says never to write the key on the drone, never to share it, and to avoid writing it down at all. Delete the number from any drone you sell or lend, and if you think someone else knows the key, ask the CAA for a new one.

Which aircraft need an Operator ID

You need an Operator ID for any drone or model aircraft of 250 g or more, and for one from 100 g that carries a camera. Between 100 g and 250 g without a camera, it's optional. A Flyer ID is needed from 100 g, whatever the aircraft carries. Check the fleet against these rules, not against what someone remembers from a briefing.

For most commercial fleets the 100 g rule changes little, because inspection and survey aircraft sit well above 250 g. The one to watch is the small camera drone kept for quick site photos or training. If it has a camera and reaches 100 g, it needs the label, and it's easy to miss.

Remote ID and class mark dates

Renewal day is when the whole fleet gets looked at anyway, so check it against the UK Remote ID and class mark dates too. The UK0 to UK6 codes are UK class marks.

• Remote ID, from 1 January 2026: UK1, UK2 and UK3 aircraft, and UK5 and UK6 aircraft flown in the specific category, must transmit Remote ID.
• Remote ID, from 1 January 2028: UK0 aircraft of 100 g or more with a camera, and UK4 aircraft (model aircraft, for example). The same date applies to camera aircraft of 100 g or more that have no UK class mark (the CAA calls them legacy aircraft) or were privately built. The CAA's page adds that from that date Remote ID applies to all drone and model aircraft operations, unless you have an exemption.
• Class marks: a new model placed on the market from 1 January 2026 must carry a UK class mark. An aircraft with a European C class mark can be flown as the matching UK class only until 31 December 2027.

For a fleet built before 2026, the 2028 date is usually the one to plan for, because aircraft with a camera and no UK class mark land there. The CAA's Remote ID page has the full table.

What to keep on file

An inspector, a client or an insurer can ask whether your registration was current on the day of a job, and the label can't answer that. What can is a short record, checked before a crew mobilises: the Operator ID with its expiry and last renewal date, each pilot's Flyer ID and any A2 Certificate of Competency they hold, and the date each aircraft was labelled and each contractor checked. Leave the Remote ID private key out of it.

Kept like that, renewal day is a quick review rather than a search through old emails, and the question "were you registered on the 14th?" has an answer on the spot.

If your Operator ID has already expired

Don't fly the aircraft it covers until you hold a valid Operator ID again: flying on an expired one is flying unregistered. The CAA's guidance doesn't say whether an expired ID can still be renewed or keeps its number, so contact the registration team (details above) and ask. Once it's valid, run it through the check service and compare the number with the labels before the next job.

Closing thought

Operator ID renewal is a five-minute task with a twelve-month consequence. The risk is easy to picture: one careful person sets it up, it runs quietly for a year, and it lapses the week that person is on leave or has left. That's why the date belongs to a role rather than a name, and why it gets checked every time a crew mobilises, not once a year.

In FlybyOps the registration record can be attached to each job when it's planned, alongside the assigned pilots and the equipment registry entry for every aircraft carrying the label, so the ops lead sees it before the crew leaves. It sits in the programme's own encrypted workspace, each role sees what it needs, and the append-only audit log shows who changed it and when.
