georgio: can't find out where you are situated from your postcode,but from what you say, it looks like you may be a distance from your nearest tv transmitter, as you say, you can pick up freeview on the main tv, but the upstairs tv using a indoor aerial can't pick up any signals.
Personally, i'm a strict advocate of having the tv earial on the roof to obtain the best signal.If the signal is too high, you can turn it down with an atteunator.If the signal is low after switchover, having an indoor earial will make it worse.The best thing to do is use a high gain earial on the roof, that way you can then join up two tv's ofF the one earial, with a little decrease in db gain from the earial. Hope this is of use to you.

The new COM 8 multiplex is up and running on the 31 main transmitter sites across the UK. A More accurate information sheet has been released about it. It states, that the COM 7 and COM 8 multiplexes from Sutton Coldfield has the following ERP. The COM 7 multiplex ERP is 89.220 kw, and the COM8 multiplex has an ERP of 85.990 kw.

Both the COM 7 and COM 8 multiplexes are at a temporary ERP and frequency channel slot till the big switchover in 2018, when each transmitter site will be allocated 6 multiplexes each between 470mhz and 600mhz. All multiplexes will be in HD. However, this is all open to change, if they can agree on a new codec for the proposed 4K specification. The current one which folk are raving about is the N-NOVA PERSUES compression codec.If this happens, we will get a lot more standard HD channels and perhaps 4K being transmitted terrestrially. From what I've read, in tests, they have stated that they can create a good, stable 4K stream with a bit rate of 7-8mb, which is enough to transmit 4 4K channels terrestrially per multiplex, and up to 9 standard HD channels. The only downside is if the current standard HD and 4K televisions will be able read the new codec information, or whether television owners will have to purchase or use yet another set top box? WE shall see.
