I can't find any reports of faults at Belmont, and work did continue last week but as far as we know the work was completed and was just routine maintenance.
What has been an issue though is the weather conditions.
There has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days.. Do NOT retune, it will more likely remove your correct tuning.
These conditions are predicted to ease late on Wednesday by the end of the night

Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted. It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
The BBC have had a warning on their Works and Warnings page for a few days, and Freeview had added one today - Wednesday (better late than never!) but at the time it was then mainly affecting the S & SE.

The Planned Engineering continued last week but has been completed as far as we know. What has been an issue for a few days is weather conditions.

On the contrary paul, there has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days, it sometimes accompanies high pressure.
Do NOT retune, it will more likely remove your correct tuning.

I suspect you mean UHF Channel 55, COM7 which carries BBC4 HD and BBC News HD. It's weather conditions.

Others have had similar issues. There has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days, it sometimes accompanies high pressure.

Hi paul. Do remember they are all general propagation predictions and it doesn't mean that one WILL be affected, sometimes just bands II & III may be affected and not IV & V, sometimes the other way around, sometime all or none!
dxinfocentre is one of the ones I refer to, also Europe | Tropospheric Propagation Forecast
It's worth keeping an eye on Problems with Freeview reception? | Help receiving TV and radio as the BBC sometimes put a Works and Warnings note up (there's been one but it will usually disappear when conditions change).
I do look at Updates and alerts | Freeview for other things but they're often unreliable for this sort of thing (always after the event, so to speak, as with some other things they put there!).

David Mirylees:
I would not rush to do anything right now. It may not be too much signal, but that shouldn't be dismissed as it's still a possibility.
There has been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK at present. Do NOT retune, it will more likely remove your correct tuning.
These conditions are predicted to ease later on Wednesday by the end of the night, but should have cleared most of the SW by now.

I would wait and see if conditions and reception are more stable now for a couple of days.
