Re Daniel Tristan's question,
It might be worth checking that you are using an antenna of the correct group i.e. wide band and of the right sensitivity. heavy birds perching on it could move it some what but I feel it unlikely. The grouping is colour coded with a plastic peg in the end of the square section which the antennae's elements are attached it can be mistaken for a bung in each end of beam and for Sandy Heath TX you need to select an antenna with a black end bung. If you goggle the data you should be able to find out about this aspect/data.
From your comparison with your mothers reception its should be you getting the most channels but the way you seem to be missing all the BBC channels could be that your antenna is tuned to not cover the frequency range on which the BBC is broadcasting where as maybe your mothers is of the correct group and so out performs yours. It is worth considering the condition of the cabling from antenna to TV set. the best set up is one with no joins except at the ends where you have the connector for the TV and the roof end where you terminate cabling to antenna and use the highest quality cabling made this is worth checking on line to avoid falling foul of any poorly trained sales assistant whose tech knowledge could be better some high street sellers sell kits of all the items you might need I.E bracket antenna screws wall plugs and the cable the bracket often lets pole move out of line away from vertical the antenna will be a cheap flimsy item and the cabling is just better than wet string and the wall plugs and screws .......? you get what you pay for in this world. should your existing antenna prove to be of the right grouping then carefully check existing cable to roof it should not have any sharp bends any where on its route to TV set have foil and a tightly woven braid with decent internal insulation hard for you to know that something that's learn by experience over the years with no stable pins puncturing through it as these could act as a " Tuned stub" shorting certain frequencies to earth something radio armatures often use to eliminate RF interference and its not impossible for you to be unlucky and have a pin in just the right place through cabling for it to work against you.

Rodney: You havn't given a postcode, but you have the classic signs of too high a signal strength. Search for 'too much of a good thing' on this site

Hi, tonight (9/6/15)I was watching a film I had recorded on my BT Vision box, when I had finished watching my film, I went to watch normal tv, only I couldn't as my BT box said no signal, as did my free view tv. I checked the signal status of the Sandy Heath Transmitter as that is my local tower, only to find that apparently it has no issues at all, so could anyone please explain to me why I have lost EVERY free view channel on my TV and vision box?
Many Thanks

kai: if its not them, it must be you. Your manual will give the probable answer - your aerial has a fault, so there is either no signal, or so little that its not happening. Checking the aerial lead from the wall is a good satrt, and then follow it back from there.
