Hi,

Follow the below mentioned steps to reduce your loading time.

1.Compress your CSS, HTML and Javascript files using Gzip to reduce the size of the file.
2.Compress image file size by using Photoshop.
3.Optimize your code by removing spaces, commas, unnecessary characters, comments, formatting, and unused code.
4.Reduce redirects and use direct URLs in the website internal links.

As mentioned above, if my website's loading time is very bad & I don't have ways to improve it anymore. What is the next step that I should take?? Change the theme?

Note - Site is designed with multiple templates from diff themes(WP)

With WordPress you can not do anything without plugins and each plugin is a block of code and the more code you add to your site the slower and more hаck-able it becomes.  You need to optimize all your images, and remove all your plugins and check your load times, then only add the plugins you need and check the load times again. One at a time as you add them and see which plugins are causing you the most problems.

If your using a Bootstrap theme drop it and go with a pure CSS layout.

As you said you dont have ways to improve it anymore,
so what you have done till the date?
Contact your developer and you can remove CSS and JS which are not required.

This is the main reason which is making site slow. Because as you already mentioned, you've used multiple templates to make one website.
Now your current website is having too many CSS and JS (if you havent modified/filtered)

So, if you are good with JS & CSS, try to delete the extra one to reduce the loading time. Because it's impact is high!
I hope this help you. And ask me back if you have doubts.

A large volume of unoptimized images is usually the most common reason behind website slowness. High-resolution images can consume lots of bandwidth while loading. Uploading larger sized images and then scaling them down can unnecessarily increase the size of your web page – causing your website to load slowly

Do a website audit and find what is the thing which is impacting website speed. Optimize and enjoy the speed!
