I have tried several hosts for my new experience with WordPress, I wanted a UK host with a money back guarantee so that I can test the service with several plugins installed.
HostPresto is now becoming my main host for my sites that are more demanding. Their backed is cpanel (linux) which I am used to and the upload speeds are very fast. Support is very good even on weekends. They have all the standard software 1 click installs including WordPress, Magento etc. 30 day money back guarantee if you want to try the service and ensure it meets your requirements.
SmartHosting (also known as BestHosting) offer great value as there is a single low monthly fee but you can add unlimited domains via the cpanel Add Domains feature. I use this for starter websites, domain holders etc. So far they have been very reliable and I have several sites set up with them. Support has been very quick which is always good. They offer a 30 day money back guarantee.
TSOHost is another provider I used, they have a very good reputation for reliability and their pricing is very competitive. My only dislike was the cloud control panel which found clunky and lacking features, they also offer cpanel so I will return to them and take up a cpanel package in the future. They own their own large data centre and they would be a good choice for users requiring their own dedicated and managed servers. I have a special 10% off hosting coupon to use with TSOHost, enter code iuseful and receive a 10%discount.
