My mother has not had anything on the main channels since the beginning of last week. I see that Sandy Heath is having engineering work at the moment. Would you have any idea when it is likely to be finished please?

Unfortunately Arqiva never provide detail of the work or how long it may take, as much of it could well be weather dependant!
However your mother shouldn't have been without the "main channels" all this time.
Which specific channels is she missing, are they HD or SD?
Are you able to check her aerial is still looking intact and pointing correctly?
If you provide a full postcode we can check the predicted reception and whether there's the possibility of interference.
