The tv that Clive recommends is not an LCD, nor is it priced between £600 and £900. It is an excellent tv though. Samz, is there any particular reason that you want an LCD tv and not a plasma? If you consider a plasma then you open up a lot more choice in sets, and plasma tend to be cheaper than LCD.
That's not to say that there aren't some great LCD sets available in your specified price range, like these:
Sony KDL-40W3000 £959
Sony KDL-40V3000 £660, both of these are superb 40" 1080p full HD LCD tvs.
Panasonic 37LZD70 around £700 - £900
Panasonic 37LZD80 around £800 - £1000, both of these are also superb 37" full HD 1080p LCD tvs.
All these prices are on the internet and may require some looking to find. If you consider plasma then you open yourself up to a whole load of other great tvs. I hope I have been of some help, and I hope that others will add to the tvs that I have listed.
