Leezig,
I have a reseller account with Heart Internet.
For sites without too much traffic it’s fine, no downtime, reasonable support, good prices.
I did move a site away from Heart that had 10,000 visitors per day as it was always falling foul of some hidden automatic disable triggers.
Heart always claimed it was some scripting problem and I wasted many hours checking/changing all sorts of things.
In the end someone there owned up and said the traffic volume overloaded my share of the CPU/Bandwidth allocation.
I moved that site to Aaron at
http://www.onesmarthost.co.uk/modx-hosting?modx and apart from one glitch the site has been fine and now has 20,000 visitors per day.
The only thing to be aware of is that onesmarthost currently only do IIS Hosting, but Aaron is very helpful.
