Visa & Appointment Availability Monitoring (v1)
How Do You Catch A 3 AM Appointment Slot?
ChangeTower checks the booking page as often as every 5 minutes, signs in and clears the banners if it has to, and emails you the moment a date appears.
✓ No credit card · First monitor live in 5 minutes
Every page here is under a monitor. ChangeTower checks it on your schedule, as often as every 5 minutes, stores a dated snapshot each time, and emails you when your criteria are met. Booking still happens on the site itself.
The screenshot ChangeTower stored on that check: the page exactly as a visitor saw it, kept with the HTML and never edited.
Detection is content-level. ChangeTower reads the words and the HTML. The screenshot is a dated record of the page, not compared against anything.
Every page your appointment depends on, in one place: booking calendars, wait times, document requirements, fees, and forms. Open a row to see what changed and how the page looked that day.
Tell it what matters. It ignores the rest.
Booking pages change all day without a single appointment appearing. Write your criteria in plain language, and only matches reach you.
Criteria in your own words.
No rules engine, no hidden thresholds. Say what deserves waking you up, and the monitor holds to that.
One rule, written once. The wait-time edit is archived quietly; the two August releases reach you the moment they are detected.
Login, cookie banner, location picker? Still watched.
Booking calendars are almost never on an open page. Record the steps to reach yours once, and ChangeTower replays them before every check.
Record the steps once. They run before every check.
Sign in, dismiss the banner, choose the centre, open the month. You record it once and the monitor repeats it.
The same four steps you would do at 3 AM, run for you every 5 minutes.
From the appointment slot alert to the booking page, dates still there.

Every monitored page captured on schedule. 1 change since yesterday, archived.
A cancellation opened for 18 Jul at 09:40, where the next available date had been 19 Sep.
Summary: The calendar went from no availability to 12 appointments across 22 to 26 Aug. Matched your rule: any slot in August or September.
Sent the moment the 03:10 check found it. Booking happens on Northgate's own site: ChangeTower tells you, it does not book, hold or reserve anything.
The booking calendar went from no availability to 12 appointments across 22 to 26 Aug. The signed-in view was reached with your four recorded steps, and only the availability table was read.
Appointments are released as capacity is confirmed. Select a date below to continue to booking.
| Date | Location | Availability |
|---|---|---|
| 22 Aug 2026 | Northgate Centre | 12 available |
| 23 Aug 2026 | Northgate Centre | 4 available |
| 26 Aug 2026 | Northgate Centre | 2 available |
Availability shown is live at the time of viewing and is not held until booking is completed.
The screenshot stored on that check: the page exactly as it was reached, kept with its HTML.
Every check in between stores a snapshot too, changed or not. All three releases in the past two weeks landed between 02:55 and 03:10, worth knowing before you plan an evening.
Turn the cadence up while you wait, and back down once you are booked. Every setting here is per monitor.
Found the booking page at midnight? Watch it from there.
Nobody finds these pages in a dashboard. You find them three links deep late at night, and the extension turns that page into a monitor.
From open tab to monitor, in one click.
No places available, but you would take anything in the next 6 weeks? Say that, and the page is monitored.
No places are currently available. Places are released as centres confirm capacity, and cancelled places return to this calendar automatically.
Places are not reserved until payment is completed. This page does not maintain a waiting list.
The next scheduled release is not announced in advance. Check back for updates.
Found at midnight, monitored before the tab closes. It joins your monitors, archived from the next check.
Every page an appointment actually depends on.
A booking calendar turns over in minutes. A fee page moves twice a year. Set frequency per page to match, as often as every 5 minutes.

Catch a cancellation while it is still open
Somebody gives their place back and it lands on the calendar without an announcement. With checks as often as every 5 minutes, the email reaches you within minutes, not the next time you happen to look.
Watch every centre at once, take whichever opens first
One monitor per booking page, as many pages as you want. Four centres, three cities, or one office across two services, all reporting into one place so you take the first date that works.
Never learn about a requirement change at the counter
Checklists, fees, and form editions change without notice, and finding out on the day costs the appointment. They sit under the same watch as the calendar, and the summary says what moved in plain language.
Learn when the slots actually drop
Every check stores a dated snapshot, changed or not, so the pattern becomes visible: when dates tend to appear, how long they last, how often they come. Guesswork turns into something you can read.
For appointment watching, turn these on.
Four do most of the work. The other two decide how you hear about it.

Alert criteria in your own words: "alert me if any appointment slot appears in August or September." Every change is summarized in plain language, and only matches reach you.
Explore →Manual User Actions
Most booking calendars sit behind a cookie banner, a sign-in and a location picker. Record those steps once and ChangeTower replays them before every check, reading the page as you would see it.
Explore →Password-Protected Pages
If the calendar only exists once you are signed in, the monitor signs in too. Credentials are stored securely and used for nothing but reaching that page.
Explore →Selective Monitoring
Point the monitor at the availability table and nothing else. Rotating notices, cookie prompts, and a footer that changes every deploy stop counting. That is most of the noise on a government page.
Explore →Scheduled Checks
Set frequency per page: as often as every 5 minutes for the calendar you are waiting on, weekly for the fee table that moves twice a year. Turn it up while you wait, back down once booked.
Explore →Email Notifications
The alert lands in your inbox with the summary, so a 3 AM release is waiting when you look at your phone. Nothing to install, nothing else to watch.

How does visa appointment monitoring work?
You point ChangeTower at the booking page, record the steps to reach the calendar if it sits behind a login or a picker, and it checks the page as often as every 5 minutes. The moment a date appears you get an email. You do the booking.
Does ChangeTower book the appointment for me?
No. ChangeTower watches the page and tells you what changed. It does not book, hold, reserve or queue, and it will not fill in a form for you. What changes is timing: instead of finding a release next morning, the email reaches you within minutes of the check that caught it. Booking is yours, on the site itself.
How quickly will I hear about a new slot?
The alert goes out on the check that finds the change, so it is as fast as the cadence you set. With checks as often as every 5 minutes, a date appearing at 03:07 reaches your inbox around 03:11. Whether the place is still there depends on the page, not on us.
The booking page is behind a login. Can you watch it?
Usually, yes. Record the sign-in among the steps that run before each check, and the monitor reaches the same signed-in view you would. Credentials are stored securely, used only to reach that page. The exception is a site that blocks automated access outright: if a page will not load, it cannot be watched, and you see that straight away, not after a month of silence.
The calendar only appears after a banner and a centre picker. Can you still watch it?
Sign in, dismiss the banner, choose the centre, open the month. You record it once and the monitor repeats it.
Can I watch just the calendar, not the whole page?
Yes. Selective monitoring watches one part of the page, such as the availability table. Rotating notices, session counters, and a footer that changes every deploy stop counting, which is most of what a government booking page does all day.
Will I get an alert every time the page twitches?
No rules engine, no hidden thresholds. Say what deserves waking you up, and the monitor holds to that.
How many offices, centres or services can I watch at once?
Yes. One monitor covers one page, and you can watch as many pages as your plan allows: four centres, two cities, or one office across a visa appointment and a passport renewal. All report into one place, so you take whichever date opens first instead of committing to one queue.
What is a snapshot, and how long is it kept?
A dated capture of the page: the rendered page and the HTML behind it, stored every time a scheduled check runs, changed or not. Each one is timestamped and stays retrievable, so you can see exactly what a requirement page said on the day you prepared your documents, or work out when dates tend to be released.
Where do appointment alerts get sent?
Email, Slack or Microsoft Teams. Most people run these on email, since that is what reaches a phone overnight when a slot opens.
Can it tell me when the requirements or fees change, not just the dates?
Yes. Checklists, fee tables and form editions sit under the same watch as the calendar, so a requirement that changes before your appointment reaches you the same way a new date does.
Is monitoring a booking page allowed?
ChangeTower reads the page the way a visitor does, on the schedule you set. It does not book, queue or submit anything on your behalf, so how often you check a site is a decision to make against that site's own terms.
Stop refreshing the booking page at 3 AM.
