The site is getting busier and I think we're close to outgrowing our welcome on the shared service.
The host I'm currently with has this available as a basic VPS deal:
Disk Space 15 GB
Monthly Bandwidth 300 GB
Guaranteed RAM 512 MB
Control Panel £5
Parallels® Virtuozzo Containers Yes
Number of Usable IPs 2
Unique IP Address Yes
Root SSH Access Yes
Monthly cost £19
So the total per month, with cPanel, is £24.

Servers are really not my area so I have no idea if that configuration will support the existing traffic (usually around 75-100 visitors) or whether I need something more.
Current disk space usage is 1GB and monthly bandwidth is 15GB.
I need managed and cPanel as I don't have the time or knowledge to maintain a server myself.
I would also prefer a UK based host.
Please don't suggest Linode as I don't want unmanaged.
