Assuming that you might want a more modern television Steve, then I'm going to suggest two models. One is the Samsung UE48H6400, from John Lewis,
Richer Sounds etc. It has good reviews everywhere,
from What Hi-Fi, from HDTV test for the 40-inch version, and from Trusted Reviews.One thing that I keep mentioning that the reviews gloss over, is that the stand swivels, which is actually quite useful. Everybody had been loving the H6400 series, and I thought that the 65-inch version of it in London six weeks ago looked pretty good, though it's only 1080p, not 4K. John Lewis will have one of the 6400 series on display, and you'll see that it more than holds its own against considerably more expensive sets. And, now at £549, it's £150 cheaper than when it got such good reviews.
The other television that I'll recommend is one of the last plasmas, the LG 50PB690V, £639 from Currys,
right here. I know that I'm the only one on these forums that recommends LG plasmas, but that't okay, I must warn you that its black level won't be anything like as good as on a Panasonic plasma, but I find that in practice the black level of my LG plasma in the kitchen is not noticeably worse than that of my acclaimed Samsung plasma in the parlour. And, the LG even has, saints preserve us, a VGA input to connect to a (Windows XP yes, and maybe Windows 7) computer. If you can still see this LG plasma on display at Currys (make sure that it's this model, not either of the two step-down models) it won't look very inspiring next to the "LED" televisions that will certainly be surrounding it, but provided that your room at home is not too bright, the LG will be fine, mine is vibrant even with an amount of daylight coming in. For bright rooms however, the Samsung might be a better bet.
Both of these sets do 3D, and are very well within your £1,000 budget. Hence, I would urge you to get your set, whichever you decide on, (and there are capable alternatives to the two that I've given, expecially from Sony) get it calibrated. This will cost between £200 to £250, and I think that it is very worthwhile. I had all four of my televisions calibrated in summer 2013 (with a bulk discount), and I'm still loving the results, and it saddens me slightly that so many people are living with televisions that are not performing nearly as well as they could. Google the names of Stephen Withers, Vincent Teoh and Canary Jules (he's a Norwich City fan!) for calibration services.
And you'll still have change from your grand. *dance4*
