The Planned Engineering may not be helping, but you are only 17km from the transmitter with a clear line-of-sight and there are no specific faults listed, so the most likely cause will be the recent weather conditions.
Severe Tropospheric Ducting occurred with the recent high pressure.
It was unusually intense on this occasion. It can be quite variable, come and go within seconds, minutes or hours. It doesn't necessarily affect all multiplexes at the same time or at all and not everyone will be affected, it will depend on location. At times it can wipe out your reception.
People in different parts of the UK and Europe have been experiencing problems.
Do NOT retune. IF you had been correctly tuned it is never advised to Retune when you've lost signal or it's badly pixellated be it due to weather, engineering or faults etc. as it can often clear your correct tuning. You just have to be patient and wait for normal conditions, you can't tune to signals that aren't there or have bad interference.
If you did retune at any point and channels are missing from your EPG then the best option is to try a manual retune for the multiplex UHF channels that you are missing.
See Channel listings for Industry Professionals | Freeview for a full list of which TV programme channels are on which multiplex.
The correct UHF channel numbers are listed in the top section of the page (although the TV programme lists may not be up-to-date).
As far as the Planned Engineering is concerned, I'm afraid Arqiva never give details of the work or how long it will last, especially as some may be weather dependant.
