The first and biggest thing on your homepage should be utilised.
This is the line of text that is the main heading, usually the first thing after the ‘header section’ with the site navigation menu.
If you go to my home page you will see my heading is “Websites for Artists and Artisans” https://www.tombstevens.co.uk/
Saving it as a H1 tag in your page editor tells search engines that “this bit is the important heading”.
You should only have 1 H1 per page by the way.
Instead of “ABC Solutions Ltd established 1987” as your H1 heading use something that includes keywords for your services, e.g. “Graphic Designer in Coventry, Brand and Logo Specialist”.
