Rates for web hosting vary significantly from one web host to the next. As a rule of thumb you should expect to pay more when more features are included. Over the years as more competitors come into the market rates have reduced significantly. Price should never be the only deciding factor when choosing your web host. For instance you may come across several options for free web hosting in UK but this should never be a consideration for a professional site. Free hosting should only be reserved for personal sites where you plan to share things with friends and family.
Any web host that you choose should offer an uptime of at least 99%. Today many of the more reputable providers strive to meet this standard so that customers will not have to be too concerned with their sites going down due to the unreliability of their service.
