The pan-European Stoxx 600 index was down 0.17 percent, with regional bourses and sectors mostly pulling back. Mining and tech stocks were both down by 0.66 percent. The Stoxx 600 index closed higher on Tuesday.

In Europe, U.K. inflation figures for August were published Wednesday. According to Office for National Statistics data, it was 2.2 percent, unchanged from July and in line with expectations.

The data comes ahead of the Bank of England meeting and interest rate policy decision scheduled for later this week. It is a busy week for central banks, with the Bank of Japan and the U.S. Federal Reserve also scheduled to meet.

The Fed is all but guaranteed to announce an interest rate cut on Wednesday, which would be its first since starting to hike rates in March 2022.

However, traders are split about the magnitude of the cut. According to CME Group's FedWatch tool, chances of a 50-basis-point reduction have been rising recently and last stood at 65 percent.

U.S. stock futures changed a little before the Fed decision. Asia-Pacific markets were meanwhile mixed on Wednesday.

The final reading of eurozone inflation figures for August is also due.
