Best Time to Post on Social Media in the UK (2026)
Nearly every "best time to post" chart online is built on US accounts in US timezones. If your customers are in Manchester or Margate, that advice is off by five to eight hours. Here's a UK-first starting point — and, more usefully, how to replace averages with your own numbers.
UK starting points by platform
Treat these as a first guess to test, not a rule:
- Weekdays 12:00–13:00 (lunch break scrolling)
- Weekdays 19:00–21:00 (post-dinner peak)
- Sunday 18:00–20:00 — often the strongest single slot for consumer brands
- Weekdays 09:00–10:00 and 19:00–21:00
- Older UK audience skews earlier in the evening than Instagram
- Tuesday to Thursday, 07:30–09:00 and 11:30–13:00
- Almost nothing lands at weekends
TikTok
- Weekdays 18:00–22:00, with a smaller 06:00–08:00 commute window
Watch the clocks: BST vs GMT
UK clocks change twice a year. If your scheduling tool stores times in UTC, every scheduled post shifts by an hour each spring and autumn. Check your calendar the week after the change — it's the most common cause of a sudden, unexplained dip in reach.
Find your own best times (better than any chart)
- Export the last 90 days of posts with their publish time and first-hour engagement.
- Split by format — Reels, carousels and single images rarely peak at the same hour.
- Plot engagement against hour of day and look for two or three repeating peaks.
- Check where your audience actually is: a UK business with Irish or US followers has two peaks, not one.
- Test one new slot per week; don't change everything at once.
Below roughly 500 followers there usually isn't enough signal to learn from — use the starting points above for your first 60 days, then switch to your own data.
Letting the timing run itself
Once you have 90 days of history, timing is a solved problem you shouldn't be doing by hand. A scheduling tool with per-account time prediction picks the slot for each post, and automation keeps the queue full so there's always something to place.
