The words are being joined by non breaking spaces , so the browser doesn’t break them. Try deleting the spaces and add them again manually by hitting the space bar.
This is usually caused by copying and pasting text from another source which supports special characters. Check screenshot below for reference. http://imgur.com/pgaUnQl
I’d just chime in here. I’ve just checked this Website http://www.communitywhitecollarboxing.co.uk/ and I realized that the word “PROFESSIONAL” is too large to fit on a mobile screen and that causes the white space on the right side. I’d suggest using a Heading Module to insert your texts there and set a custom font size for the Mobile Structure. Doing this will allow you to display different texts size on mobile screens. I’ve attached a few screenshots below for your reference. Let us know how it goes.
Glad that worked for you. If I’m not mistaken, do you have this CSS snippet below in your Custom CSS? Maybe it is used somewhere within your site and that’s what causing the issue there. Let us know if you need anything further.
