I see the offering of web hosting by Plusnet as something more for personal use or possibly a mainly textual information site. Possibly somewhere to dump a few pictures on for family and friends.
I run my own web and email servers so I'm not constrained by any limitations imposed by the host (apart from the T&Cs of my ISP obviously). It works well but costs around £100 a year in electricity alone and then there is the hardware to worry about (and the constant attack by hackers etc etc).
The biggest problem is that with the increasing hits by search engines which also download and cache pictures, you can find your traffic rapidly increasing and 100Mb these days can be downloaded in a few seconds.
