The one good thing I can say about it is that the navigation is consistent, being that it doesn't change.

I personally would first of all, use a better color selection. Unless you have an impressive design those yellows just won't do. I would suggest using some basic complementary colors, since design doesn't seem to be your focus.

I would also, suggest getting rid of the frames. Frames suggest old to me. The look is more or less something I would expect to see in the late 80's when the internet began to take off.

Try using a higher quality pic of the doc. If you want to sell business you have to look professional. I'm not sure what the internet market is like in South Wales, but site quality generally represents your quality of business. Also, try putting an identifier on all the linked pages, something that represents the doctor.

The Yellow block highlights on the side need to go. That color is just not doing it for me.

I would maybe use a graphic for the titles to give a smooth and less pixelated look.

A nice clean presentation is the key. Work on that and you'll have a better site. By the way it looks like you did the site for free :). Maybe he'll pay you for a better one.
