How can I boost my download speed?

So.. My download speed is a minor 0.7mb and I'm with Sky Broadband which is meant to be 20mb! It's just me with the internet right now and no other devices other than my laptop..

How is my download speed so slow when everyone elses should be 6.0mb minimum?

And is there anyway I can boost it?

Hi you can follow the below steps to increase your internet download speed:
1)Delete all cookies and temporary files.
2)Use different browser. Because normally some browser enabled java script
and flash video ,so the webpages is loaded very slow.So you can try it
different browser.
3)Virus,malwares is also another important thing it will make a slow connection.
So use a good antivirus software to remove all virus and malwares .
