The best time to post Instagram Reels in the UK (2026)
Published 14 May 2026 · Updated 24 October 2026
Quick answer
Weekday evenings: Monday to Thursday, 5–9pm UK time. That is the window in Sprout Social's 2026 UK data, from 21.6 million UK Instagram engagements. Buffer's global data also points Reels towards evenings, with Wednesday and Thursday strongest. Saturday is weak in both.
For a UK audience, the strongest evidence for Instagram points to weekday evenings. Saturday is weak in almost every study. The studies disagree on the best single slot, and that is a sign your own followers matter more than any average.

| Study | What it looked at | Best times | Weakest |
|---|---|---|---|
| Sprout Social, UK | 21.6 million UK Instagram engagements, times in GMT | Mon–Thu 5–9pm. Best day: Sunday | Saturday |
| Buffer | 9.6 million Instagram posts, all formats | Thu 9am, Wed 12pm, Wed 6pm. Suggests 6–11pm for Reels | Friday and Saturday |
| Hootsuite | Over 1 million posts | Mon 3–9pm; Tue 5–8am and 3–7pm; Wed 5pm; Thu 4–5pm | Before 8am and after 10pm |
| Sprout Social, global | About 2 billion engagements, Nov 2025 to Feb 2026 | Tue 1–7pm; Wed 12–9pm | Saturday and Sunday |
| Later | Over 6 million posts, 2024 | 5am overall; midnight for Reels | Saturday |
Apart from Sprout Social's UK report, these studies adjust their times to each audience's own clock. That means the hours apply to UK followers in UK time.
Where they agree
Weekday late afternoons and evenings run through most of them. Sprout Social's UK data has Monday to Thursday, 5–9pm. Hootsuite's Monday and Tuesday windows run into the evening. Buffer suggests evenings for Reels and has Wednesday and Thursday as its strongest days.
Saturday is weak in Sprout Social's UK data, in Buffer's and in Later's. Sunday is split: Sprout Social's UK data has it as the best day, while its global data rates the whole weekend low.
Later is the outlier. Its 2024 data found very early mornings, 3am to 6am, gave the highest engagement, and midnight for Reels. Later measures engagement rate, which can run high when few accounts are posting. Few people want to post at 5am, but if you schedule posts, it's a cheap test.

For lifestyle, fashion, education and beauty, our starting windows are earlier in the day than the studies' overall evening peak. Each has a later weekday slot in the "also worth trying" column (4–6pm for education, 7–9pm for the others), so test both. If your insights show your followers are most active in the evening, go with that.

Check your own followers' most active times
Instagram shows this directly, if you have a professional account (creator or business) and at least 100 followers:
- Go to your profile and open your Professional dashboard.
- Open your account insights, then the Total followers section.
- Scroll to Most active times and switch between Hours and Days.
Check a few different days. If your followers' busiest hours sit outside the windows above, trust your own data.
Clock changes
UK clocks go back on 25 October 2026 and forward on 28 March 2027. If your audience is in the UK, keep posting at the same UK clock time. If you schedule Reels, check your scheduler's time zone after each change.

If your audience is outside the UK
Aim at your followers' local time, not yours. US Eastern time is usually 5 hours behind the UK, so a 6pm Reel in New York means 11pm in London. The calculator on our homepage converts any niche window into your own time zone for any pair of cities.
Give it time
Try a window for two to three weeks, posting Reels of a similar type, before you judge it. One Reel tells you more about the content than the timing.
Questions people ask
Is the best time for Reels different from feed posts?
Possibly, but the big studies mostly measure all post types together. Buffer says its Instagram times combine every format, and suggests evenings for Reels. Later found very late-night posting worked best for Reels in its data. Test Reels separately if you post both.
Why does Later say 5am?
Later's 2024 data found posts published between 3am and 6am got above-average engagement. That is unusual among the studies and few people would choose to post then. If you schedule posts anyway, it may be worth a test.
Where do I find my followers' most active times on Instagram?
Switch to a professional account, open your Professional dashboard, then the Total followers section of your insights. It shows the most active hours and days. You need at least 100 followers to see it.
Should I avoid posting at weekends?
Saturday is weak in Sprout Social's UK data and in Buffer's and Later's global data. Sprout Social's UK data has Sunday as the best day, though, so Sunday is worth testing.
