Mix a couple of tablespoons of flour with a teaspoon each of mustard powder, salt and ground pepper and rub it all over the joint. Sit it in a roasting tin on a layer of thickly sliced onions and start it off in a demonically hot oven (240c/gas 9) for the first 20 minutes. Turn it down to 180 and cook it for another 15 minutes per 450g (so about 35 mins for yours). That'll cook it to 'rare'. If you want medium, add another 15 minutes, if you want well done another 15 on top of that. When it comes out transfer it to another warm dish to rest (and cover in foil and a couple of teatowels) if you want to use the juices and onions to make/add to your gravy.

So:
20 at 240/gas 9
35 at 180 (for rare)
(+15 for medium)
(+15 for well done)
30 mins minimum to rest

I would go onto Google, where there are many recipes for Beef, I would pick the one I liked the sound of, and then follow those instructions.

12.5 mns per half kg at 180 after 15 mins at 220. Then rest. Or until internal temp is 55 degree then rest
