Jim: Go to Find out how to receive Freeview and Freeview HD | ukfree.tv - independent free digital TV advice and click 'By Direction'. That shows the bearing as 102°, slightly south of east.
A compass will not quite show the right bearing because these bearings are east of true north, while the compass needle points to magnetic north, a few degrees different. However, the aerial has a relatively wide cone of acceptance so it doesn't have to be that accurate - just adjust the aerial for best results. (RG47SH)

There seems to be a problem with Sandy heath, caused I suspect, by a duplication of channels on MUX ch 27 & 67.
It seems OK to start with, but a few hours later, BBC1 etc VANISH!
The cure seems to pull the aerial plug out, so the re-scan misses ch67 - if your box does not tell you which channel it is scanning, there will be a percentage bar, over 75% will be the point to "pull out"
This may not be a problem with some boxes, but it certainly was with an old PVR Goodmans GHDD1782

I've also had problems with a Sony VTX-D800U freeview box as reported by Dave Kimber, where (after retuning) BBC2 keeps switching to BBC1 after a few seconds.
Following Dave's advice, the problem went away after a mains power cycle.

Re-tuned television, freeview box, strong BBC 1 & 2, no ITV, Channel 4 or 5. Freeview box is a Wharfdale TU160DTR, television is Samsung LE40R73BD.
We have previously received ITV & channels 4 & 5 although not good signals.

Menna: check for a loose, disconnected or broken cable, because you should be getting perfect reception. Also, if you retuned before 6am on Wednesday, retune again - all services were off-air at that time.
If you didn't retune at all on Wednesday, you would have lost BBC channels but should still have all the others.
Some boxes auto-retune every night and could have been confused when the services were off air.

David Brient: if there's a time of day that you've noticed that ITV, C4 and C5 were normally working, try retuning it then. Or try a manual update of channels on C45.
You are predicted to have variable reception of these channels at the moment. No problems are shown once switchover completes on the 13th (10 days time).

Thanks very much to Dave Kimber - I was having similar problems with the Sony DTX-V800U box. BBC2 would switch to black a few seconds after closing the EPG (but fine all the time the EPG was visible) - even after a full re-tune.
Power cycling the box completely seems to have cleared the problem!

I am in the Cambridgeshire and feed off the Sandy Heath transmitter. When I did a rescan on the 30th. I was left with three selections as follows:
Cambridge and Beds. 18 services
Cambridge and Beds. 21 services
Midlands. 18 services
I know that I can ignore the Midlands(Waltham) but which of the other two should I select, I can only select one.
