Hello. I can see that the current price for getting WordPress is GBP 240 (or whatever others see) as a one-year purchase. My question is, is there a way to purchase WordPress for business on a monthly basis, meaning GBP 20 per each month? 240 is a bit much for me to pay immediately…
Yes, Many web hosting provides monthly plans too.
I have used Godaddy extensively. You can check their different WordPress hosting plans. Many plans have lower WordPress website rentals.
@Morganfreeman Sure Today’s mostly web hosting companies like Godaddy,bluehost etc give you a monthly plans for wordpress.com plans. 
İ Prefer you Search about wordpress.org and built free website in your Local hosting, if you are interested i will guide you through through the process.
hope this information is very helpful for you.
