David Allen: The tuned UHF channel number is usually given on the signal strength screen. For BBC One it should be 55 for Tacolneston but perhaps it is 22 from Belmont or 27 from Sandy Heath. If so, having the aerial unplugged for the portion of the scan where the unwanted channels are may be a workaround.
Is there a preference for or choice of region/network as this is different for each transmitter region. For example, Belmont is something like "E Yks&Lincs". Maybe you need to set a preference for whatever Tacolneston is.

David Allen: Does your TV have Freeview built in? If so, then can you get ITV on UHF channel 59, rather than 25 or 24 which are Belmont and Sandy Heath respectively.

Margaret: I'm looking at photos of your location on Streetview and seeing buildings that appear to be served by communal aerial systems. Therefore if the fault is not within your equipment or wiring then it needs reporting to the party responsible for rectification.

steven: No.
By my reckoning your aerial points to the Berwick relay transmitter, at 322 degrees. This only carries the channels you have.
Your friend must be receiving from Chatton which is the main transmitter and which carries all channels.
The reason for unlikely to be unable to receive from Chatton is caused by the fact that you are nearly at sea level and that the ground rises up steeply a short distance from you, i.e. you are at the bottom of a drop (in the direction of Chatton which is 158 degrees).
See this plot of the terrain between you and Chatton:

Freesat is probably your best bet for more free-to-air channels.

Steve: Digital television, as with digital radio (DAB) is broadcast in multiplexes whereby each multiplex (which is a single signal) carries multiple services. BBC standard definition TV and radio are all on the same multiplex, hence you've lost reception of that multiplex (PSB1).
Maybe your problem is caused by the signal level being too high, but this is likely only in really strong signal areas. Or maybe PSB1 is on UHF channel 60 which is the closest to the 4G in the 800MHz band and that is the problem. Without knowledge of your location it is impossible to know whether these could be the reason.

lynn: Are the trees, seen on satellite images, in line with your aerial?
At 22 miles from the transmitter, with apparent line-of-sight (assuming no obstructions on the ground), you shouldn't have a weak signal, so a booster should not be the first thing to try.

S Martin: Maybe because they don't have HD (DVB-T2) tuners in. As MikeB says, makes and model numbers will allow that to be checked.
