Website load time is slow, any ideas?

Hi support team,

Our website is taking a while to load. We don't have any access plugins, and only have a few pages on the site at the moment.

Additionally, during the load time, a loading wheel icon appears on the page before it loads, as seen in the picture below.

What could be the possible reason for a slow loading time? How can we fix it?

Thanks in advance,
Tushar and Andrew
