Alverton isn't listed this week, but any work last week may not have been completed and sometimes these lists are not 100% reliable if past experience is anything to go by! Additionally it's a relay of Redruth and that is listed again this week so any work there may be affecting Alverton.
What sort of problem is the customer experiencing?

Hi Chris. Thanks for the info, yes, weak signal and missing channels.
I wish they would make this information more widely available
Back in the day they used to put a message on screen occasionally
to advise viewers, saved a lot of wasted time
and frustration

Oh yes, quite right, I'd forgotten about that - Arquiva and Freeview could be more helpful in that respect, but maybe that's hoping a bit much. Freeview these days, now that the 700MHz Clearance has been completed, only seem to be interested in promoting Freeview Play and dumb help on how to retune when you haven't got a signal - one of the worst bits of advise going if you were correctly tuned, as it usually just ends up clearing the correct tuning whilst there's no signal!

It might be an idea for the customer to check in their tuning section that they are correctly tuned if using the Alverton relay UHF channels are C27, C24 & C21 that's in the order PSBs 1-3.
If they'd retuned at the wrong time they might be getting Redruth signals of the back of the aerial - it's UHF channels are C44, C41, C47, C48, C33, & C32 in the order PSBs1-3, COMs 4-6.
If the set has an auto-retune function on no signal, best to turn it off if possible, more trouble than it's worth - rarely need a retune these days, usually only when a commercial broadcaster has changed a channel on one of the COM muxes and there's usually an on-screen pop-up to advise that.
