Firstly, check your aerial - the most likely cause of your problems.
Have a quick look at it - is it still horizontal? - if it's old it may have slipped after a fat bird landed on it! - don't laugh, it does happen. The aerial should be horizontal and not at a sharp angle up or down.
If the aerial is communal and your neighbours have the same problem as you, find the person responsible for it (Local Authority, your Housing Association or your Private Landlord) and get them to arrange an aerial check.
Freeview signals are more sensitive and degrade quicker than the "old" analogue signals because digital signals are currently broadcast at low power (this will change as switchover happens) to prevent interference with the existing analogue signals, and so a good aerial system is very important!
Finally you may like to consider using an aerial amplifier to boost your signal. I share a communal aerial and Freeview reception was poor so I purchased this aerial amplifier
from Maplin, who have stores all over London.
Fitting is as easy as plugging the amplifier in (it has a standard 3 pin plug form factor) and rooting the aerial cable through - a 1 minute job.
