"Engineers should not charge much at all for rotating the aerial from horizontal to vertical polarisation if roof or chimney mounted."
Not necessarily, particularly if the aerial is mounted on the roof.
Think about it, the installer still has to get in his van, drive over to you, get out all his ladders, get on the roof, do the job, get all his ladders back down on his van again, then drive home.
There are a few interesting things to consider about aerial installs and there pricing here :
Prices etc
I`ve no axe to grind with this one, we don`t really do aerial installs anymore, and definitely not out of the Sheffield area !

On retuning 21st March, I lost all Mux 33 channels including Sky Sports 1 and 2. UK Digital tell me my signal on Mux 33 is now variable but will boost on 18th April ! A warning would have been nice or perhaps they can pay for month subs ! By variable, it seems that means so far numerous tunes per day, either Mux not detected at all, or detects mux but no channels ! I asked them if they can get engineers to put signal strength back to level it was from 7th march as it worked perfectly then.

I retuned my TV on 21st March and BBC News Channel moved from channel 80 to channel 801. I then retuned manually but that didn't fix my problem. There was no problem after the 7th March retune.

My aerial is on the roof and reception is good.

Out of interest, the "Transmission Frequencies After Wednesday 21st March 2012" towards the top of the page don't appear to match the "Freeview Multiplex List" channels?
This adds to an already confusing situation :(

@Patrick
That's happened because you have picked up channels from another BBC region as well, different equipment behaves differently when it finds duplicate BBC channels, if its HD channels newer equipment should ask which region to use
I found the easiest option is to delete the BBC channels and then do a manual scan of C24 if its done similar with the HD channels then do the same thing and do a manual scan of C21

Just to add to what I wrote above I meant to say delete "all" the SD BBC channels or all the hd channels then do a manual scan of C24 or C21

Pete: The signal strength is the same as it was, but they have changed the mode of Mux B so that it has enough capacity to even carry Sky Sports 1 & 2. This mode change is what has caused the problem, for some viewers on the edge of the previous coverage area.
Before Wednesday, the channels were carried (on a temporary basis, for regions yet to switch over) on the BBC's Mux B, but this has now changed to a completely incompatible mode in order to carry the HD channels. The 'matched' capacity had become available because the BBC shut down all the services that wouldn't fit after switchover, and squeezed some others into Mux 1. The permanent home was always going to be ArqB.
The main source of interference is probably Crystal Palace BBC Two, which will close on 4 April, so you may see some improvement then. After 18 April's retune, Rowridge ArqB will still be co-channel with Crystal Palace ArqB, but Rowridge will have had a power increase to 50 kW. If it's still a problem, you may want to consider switching the aerial to vertical polarization, which will broadcast at 200 kW.

Kev: The 'Transmission Frequencies' section should really say 'Final Situation' - it doesn't take account of the short hangover period we're now in, where multiplexes A and C are yet to convert to their final mode, and A, C and ArqB are all running on pre-switchover channels.
