It is actually very easy, just look at the Digital UK website and enter a full post code. That will show all the current channels used by your local transmitter as well as the planned changes over the next few years.

I live in Hemel Hempstead with a loft aerial pointing at the Bedmond transmitter. I lost TV reception on the 18th of April 2018 but, after retuning my TV with the 'first time' installation option, I have managed to get all the TV stations back.
The frequency channels appear to be:
C29
C31
C37
C41
C44
C47 (HD)
I no longer need an aerial amplifier now so the signal strength is probably stronger than before.

I just re-checked my TV signals.
I am also getting
C40
C43
C46
Maybe I'm receiving from the Hemel Town Transmitter as well as Bedmond.
I can't seem to get the 'London Live' station on C34 yet.

Me at Home: Hemel Hempstead transmitter uses UHF channels 40/43/46/37/31/29 and is predicted to give good reception at your postcode. Hemel Hempstead Town uses 41/44/47 and is also predicted to be good at your postcode. The local mux on C34 from Hemel Hempstead is not showing on the prediction for your postcode.

There has been a breakdown in Bushey Herts WD23 3SY in particular. Signal packed up tried retuning no good. You published on screen text that you had problems with Hemel Guildford and others but earlier on lap top you say no problem

John Day, M & Hoad: It looks like the transmitter was off air for a couple of hours earlier this evening, although the Radio & Television Investigation Service reports that it was fixed just after 9pm.
