# Best time to post on Instagram and TikTok in the UK

How to find your own posting window in the UK: GMT and BST, Instagram and TikTok follower charts, a four-week slot test, and the ASA and CMA #ad rules.

The short answer

No single hour works for every UK account. Instagram Insights and TikTok analytics show when your own followers are online, so start there. Adjust for the switch between GMT and BST, test two slots for four weeks, and label any paid or gifted post with #ad under ASA and CMA rules.

Key facts

- UK clocks go back to GMT on Sunday 25 October 2026 and forward to BST on Sunday 28 March 2027 (GOV.UK).
- Instagram shows the times your followers are most active once a professional account has at least 100 followers.
- TikTok's Creator Academy suggests posting on your followers' busiest days, a little before their activity peaks.
- The CAP Code says marketing must be obviously identifiable as such; the CMA says gifts count as payment.
- Since April 2025 UK unfair-trading rules sit in the Digital Markets, Competition and Consumers Act 2024.

Most “best time to post” charts you find online are built from somebody else’s followers, and many of them are drawn in US Eastern or Pacific time. For an account run from the UK, the answer that holds up comes from two places: the clock your followers live by, and the activity chart inside your own app.

This guide shows how to read both, how the British clock change moves your schedule twice a year, and how to test posting slots without guessing. If you plan to [buy Instagram likes in the UK](https://socipro.com/uk/buy-instagram-likes) for a launch or a new Reel, the same timing logic decides when that post should go live, because the likes only help if people see the post while they are scrolling.

## Is there one best time to post in the UK?

No. Neither Instagram nor TikTok publishes a single hour that works for every account in the country. What both apps do publish is a chart of when your own followers are active. That chart beats any national average, because a café in Leeds, a fashion reseller in Manchester and a student creator in Glasgow have very different followers.

Copying a generic chart causes two common mistakes. The first is a time zone mismatch: a peak marked “6pm” in a US study is 11pm in London for much of the year. The second is audience mismatch: a study of large brand accounts tells you little about a personal account with a few hundred followers who mostly know you from school, work or your shop.

So treat every published “ideal hour” as a starting guess, then replace it with your own numbers as soon as you have them.

## How do GMT and BST change your posting schedule?

The UK runs on Greenwich Mean Time (GMT) in winter and British Summer Time (BST), one hour ahead, in summer. GOV.UK sets out the dates: in 2026 the clocks went forward on Sunday 29 March and go back at 2am on Sunday 25 October. The next change forward is Sunday 28 March 2027.

| Period | UK clock | Offset from UTC | What to check |
| --- | --- | --- | --- |
| 29 Mar to 24 Oct 2026 | BST | UTC+1 | Charts shown in UTC read one hour early |
| 25 Oct 2026 to 27 Mar 2027 | GMT | UTC+0 | UTC charts match the wall clock |
| From 28 Mar 2027 | BST | UTC+1 | Re-check saved schedules again |

Why this matters in practice:

- **Scheduling tools.** Some tools store a post time in UTC. A Reel set for 18:00 in July can go out at 17:00 after the October change if the tool did not follow UK time. Open your scheduler the week after each change and check the next few posts.
- **Analytics in UTC.** If a chart is drawn in UTC, its peak is one hour earlier than it looks on a UK clock during BST. In winter the two match.
- **Followers in other countries.** Not every country moves its clocks on the same weekend, and many never move them. If part of your audience lives abroad, the gap between you and them can change by an hour for a week or two around each switch.

## Where do you see when your own followers are online?

Both apps give this away for free, as long as you use a professional account.

| App | Where to look | What you need | What it shows |
| --- | --- | --- | --- |
| Instagram | Insights, then Total followers | Creator or business account, at least 100 followers | Most active times by day and hour, top locations |
| TikTok | Analytics, then the Followers tab | Creator or business account | Follower activity by hour and day, where followers are |

On Instagram, the Help Center lists “times they’re most active on Instagram” as part of the Total followers insight, alongside follower growth and top locations. It only appears once the account has 100 followers, so a brand-new profile has to rely on testing for a while.

On TikTok, the Creator Academy describes the Followers tab as the place to see when your community is online. It suggests posting on your audience’s busiest days and a little before the peak, so the video has time to collect early views as people arrive. Check which time zone each chart uses before you copy a number into your calendar: if it is UTC, add an hour during BST.

Two habits make these charts more useful. Look at a longer range (Instagram lets you choose presets such as the last 30 or 90 days) so one unusual week does not mislead you. And re-check every few months, because the people following you change as you grow.

## What does a typical UK day look like for your followers?

Your chart shows the shape; daily routines explain it. Use them to form guesses worth testing, not as rules.

- **Morning commute.** People on trains and buses scroll in short bursts. Short videos and simple photos suit this better than long captions.
- **Lunch break.** Office workers often check their phones around midday. If your followers are mostly in offices, this is a slot to test.
- **School run and early evening.** Parents may be busy until the children are home and fed, then pick their phones back up later.
- **Late evening.** Students, hospitality staff and shift workers are often most active late. A salon or bar owner may find their own followers peak after closing.
- **Sunday evening.** Many people plan their week and scroll at home. It can suit posts that ask people to book or save something for later.

None of these is a promise. They are reasons a peak might sit where it does, which helps you decide what to test next.

## How do you test a posting slot properly?

A slot test only works if everything except the time stays the same. Pick two slots from your follower chart and run them for four weeks.

| Week | Slot A | Slot B | Compare |
| --- | --- | --- | --- |
| 1 | Mon, Wed | Tue, Thu | Reach and views in the first 24 hours |
| 2 | Tue, Thu | Mon, Wed | Same, with the days swapped |
| 3 | Mon, Wed | Tue, Thu | Shares, saves and follows from the post |
| 4 | Tue, Thu | Mon, Wed | Totals for both slots across all weeks |

Rules for a fair test:

1. **Keep the format the same.** Do not compare a Reel in slot A with a photo in slot B.
2. **Swap the days.** Otherwise you are testing Monday against Tuesday rather than morning against evening.
3. **Judge the first day, not the first hour.** A slower start can still win if people keep sharing the post.
4. **Write it down.** A simple spreadsheet with date, slot, format and first-day reach is enough.

After four weeks, keep the winning slot and test it against a new one. Over a few months you end up with two or three slots you trust.

## Where do paid likes fit into a UK posting plan?

Timing decides who sees a post first. Likes decide what those first visitors see. If you post a new product, a menu change or a music release in your strongest slot and add likes straight after, the people who open it during their active hours meet a post that already has some response, which gives it a fair first look.

That is the honest use: helping good work get noticed at the moment it matters. It is not a way to make a business look more popular than it is to customers, and it never replaces posts people actually want to share. Socipro does not target delivery by country, so the likes reach your post wherever your followers happen to be. Before you pay, our [link check](https://socipro.com/blog/how-our-link-check-works) shows you the post we found so you can check it is the right one, and Premium includes a refill window on likes. If you are unsure whether likes or followers come first, read [Instagram followers or likes](https://socipro.com/blog/instagram-followers-vs-likes).

## What do UK ad rules say about paid and gifted posts?

Timing is your choice. Labeling is not. If a brand pays you, gifts you something or otherwise rewards you for a post, UK rules say your followers must be able to tell it is an ad straight away. Checked October 2026.

| Rule | Who enforces it | What it says, in short | Official text |
| --- | --- | --- | --- |
| CAP Code rule 2.1 | Advertising Standards Authority (ASA) | Marketing must be obviously identifiable as such | [CAP Code Section 02](https://www.asa.org.uk/type/non_broadcast/code_section/02.html) |
| Influencers’ guide | ASA and CAP, with the CMA | Use a clear label such as #ad, up front | ASA influencers’ guide |
| Consumer law guidance for creators | Competition and Markets Authority (CMA) | Gifts count as payment; avoid #gifted, #collab or #spon on their own | [CMA guidance](https://www.gov.uk/government/publications/social-media-endorsements-guide-for-influencers/social-media-endorsements-being-transparent-with-your-followers) |
| Digital Markets, Competition and Consumers Act 2024 | CMA, Trading Standards | Bans unfair commercial practices, including hidden advertising | [legislation.gov.uk](https://www.legislation.gov.uk/ukpga/2024/13/contents) |

A few practical points from those texts:

- **Put the label first.** The CMA says it must be immediately clear the post is an ad. A label buried after the “more” cut-off or at the end of a video does not count as clear.
- **Label every item.** In a carousel or a run of Stories, each promotional frame needs its own label.
- **Platform tools help but are not enough on their own.** Instagram’s paid partnership label is acceptable when it is easy to see; if it isn’t, add #ad as well.
- **Size of account does not matter.** The CMA guidance applies however many followers you have.

The unfair-trading rules moved into the 2024 Act from April 2025, and the CMA’s guidance on that Act (CMA207) is the place to read the detail.

## Frequently asked questions

### Should I post at the same time on Instagram and TikTok?

Not necessarily. Your Instagram followers and your TikTok followers are often different groups with different habits, even when you post the same video to both. Check each app's follower activity chart separately and test each platform's slot on its own. If the two peaks line up, posting together saves time; if they don't, stagger the uploads.

### My followers are mostly abroad. Should I still post on UK time?

No. Post for the place where most of your followers live, not where you live. Instagram Insights lists your followers' top locations and TikTok shows where your audience is. If most of them sit in another time zone, convert their active hours to UK time and schedule for that, even if it means posting late in the evening.

### Do I need #ad if a brand sent me a free product?

Usually yes. The CMA's guidance for creators says gifts count as payment, so a post about a gifted product needs a clear label such as #ad at the start, even if the brand did not ask you to post. Tags like #gifted or #collab on their own are treated as unclear. This is general information, not legal advice.

### When should I order likes for a UK launch post?

Order right after the post goes live in the slot you picked from your analytics. That way the first people who see it during their own active hours find a post that already has some response. Ordering hours before you publish is not possible, because the order needs the public link of the live post.
