It depends on the amount of traffic your site receives. KingPin suggested two very good companies which provide dedicated servers suitable for site receiving high to very high traffic, but their service is expensive as well. If you're site is not receiving high amount of traffic then a shared hosting or VPS will serve your needs very well and will save you some money as well. So what kind of traffic your site receives?

Looking at your hosting needs from SEO view point, I am assuming your site is UK based, use a UK company or any company that can provide you a UK IP address. Some non UK companies such as 1 and 1 do have UK data centres.

also have a look at cmodz-hosting

I'm going to recommend holdfire.net

If you are a beginner (your question forces me to think so), i suggest you to try your hand on free hosting first. Once you see growth/profit in your site, consider upgrading or migrating to a paid host. hope it helps.
