It works for the UK, including London, Manchester, and Edinburgh, and for Central European cities such as Paris, Berlin, Madrid, Rome, and Amsterdam.
What Is the Time Difference Between BST and CEST?
CEST (UTC+2) is 1 hour ahead of BST (UTC+1). So 9:00 AM BST is 10:00 AM CEST, and 12:00 PM BST is 1:00 PM CEST. The gap stays the same all summer, because the UK and Central Europe start and end summer time on the same dates.
How to Convert BST to CEST
You can convert British Summer Time to Central European Summer Time manually in three steps.
Step 1
Start With the BST Time
Take the time in BST. For example, 3:00 PM BST.
Step 2
Add 1 Hour
3:00 PM plus 1 hour gives 4:00 PM CEST.
Step 3
Adjust the Date if Needed
If the result passes midnight, the CEST date is one day ahead of the BST date. For example, 11:30 PM BST is 12:30 AM the next day in CEST.

When Are BST and CEST in Use?
BST and CEST are both summer clock times. The UK uses British Summer Time (BST, UTC+1) and Central Europe uses Central European Summer Time (CEST, UTC+2) from the last Sunday of March to the last Sunday of October. In winter, the UK returns to Greenwich Mean Time (GMT, UTC+0) and Central Europe returns to Central European Time (CET, UTC+1).
Unlike the UK and the US, whose dates differ, the UK and the European Union change their clocks on the same days, both at 01:00 UTC. In 2026 the clocks go forward on March 29 and back on October 25. That is why the gap stays at 1 hour all year, whether you compare BST with CEST in summer or GMT with CET in winter.
| Period (2026) | UK Time | Central Europe Time | BST/CEST in Use? | Time Difference |
|---|---|---|---|---|
| Jan 1 – Mar 28 | GMT (UTC+0) | CET (UTC+1) | No | 1 hour |
| Mar 29 – Oct 24 | BST (UTC+1) | CEST (UTC+2) | Yes | 1 hour |
| Oct 25 – Dec 31 | GMT (UTC+0) | CET (UTC+1) | No | 1 hour |
Tip: If you are scheduling something between late October and late March, use GMT and CET instead of BST and CEST. The 1-hour difference stays the same, but the labels change.
Best Time for a Meeting Between the UK and Central Europe in Summer
With only a 1-hour gap, the working days of the UK and Central Europe overlap for most of the day. The UK office day starts an hour later than the Central European one on the local clock, and it ends an hour earlier.
| UK Time (BST) | Central Europe (CEST) | Suitability |
|---|---|---|
| 8:00 AM – 9:00 AM | 9:00 AM – 10:00 AM | Fair (early for the UK) |
| 9:00 AM – 12:00 PM | 10:00 AM – 1:00 PM | Best overlap (morning) |
| 12:00 PM – 1:00 PM | 1:00 PM – 2:00 PM | Lunch break in both regions |
| 1:00 PM – 4:00 PM | 2:00 PM – 5:00 PM | Good overlap (afternoon) |
| 4:00 PM – 5:00 PM | 5:00 PM – 6:00 PM | Fair (late for Central Europe) |
| 5:00 PM onward | 6:00 PM onward | Outside office hours |
A standard 9:00 AM to 5:00 PM workday in the UK runs from 10:00 AM to 6:00 PM in Central Europe.
