Some one who has had experience with those companies here will definitely put an honest review. But until then -Did you try testing their support? If not, you might want to give it a go to see how fast their response times are. You can also do a review research for both the hosts. Good luck.
As I know these hosts - rockhoster.com and hosting.uk - have the reputation of high and stainless companies.
Their support people are very attentive. I also have good feedback from visitors in regards to the server response time, which is most important for me. So far, everything seems to be meeting my expectations.
I have been using rockhoster.com for a long time and can say that the service and support are amazing.
Incredible support that answered to my 10 questions in an average of 10 minutes!
Very stable hosting.
Shared plans from hostingsource.com and theelector.com are good enough to sign up with.
They are great quality site hosting providers, with a great value, low rate for low-income person with great services and support.
