Hosting simply refers to where the files that make up your website live. You can arrange your website hosting yourself, there are numerous providers out there, and provide me with the details, or I can set all that up for you, choosing a hosting provider on your behalf and adding the cost to the bill. Typically, the cost is around £30 – £70 a year ,the cost depending on who you go with, and which package you choose. I always recommend tsohost to my clients. I find them reliable and very quick to respond to any support issues.
