Please excuse my ignorance (as always) on this matter.
Are wheel flats picked up automatically or is it left to someone to notice & report them? At Stafford today Voyager 220119 to Manchester appeared to have a good wheel flat on the front (Manchester end) car. Would someone on board report this?

I don't think Voyagers have any system for detecting wheel flats. They will either be picked up by the traincrew and reported in the repair book or they will be found during an exam at the depot. Chances are it is already known about and the unit will find its way to the lathe before long.

How long (on average) does it take for a wheel flat to be found and repaired- all trains that is, not just voyagers.

Some trains seem to suffer from them more than others. For example, HST's seem to have them a lot, yet it's rare to see (or should I say hear!) a 225 with one. Is there a reason for this?

That depends on the severity of the flat(s). There are maximum tolerances which the rulebook gives as 60mm although from memory some freight wagons can be allowed to 80mm. In my experience small flats can be left for a couple of weeks and lager flats or if the tread has a few flats then it will be dealt with as quickly as the vehicle can be booked onto the lathe.

Going on from this how many times or should I say how much metal can be removed before the wheel has to be re-tyred? If that is what they do. Or do they replace the wheel?

No automatic detection. Staff report and put in book. Then its a case of waiting till the set gets back to CZ and a visit to the lathe
If you (collectively I mean) as a driver (or other member of staff were to) does the onboard crew (well, driver mainly I would have thought) have the authority to take the set out of service?

There are a number of Wheelchex sites around the network that will pick up a flat that's big enough to exert a force of more than 200 KN on the track.

Yes although it depends how bad the flats are.

When I've spoke to fitters they say they hope to get seven turns before being replaced

The wheel life is different for each type of wheel set as is the number of "turnings" a wheel can have before it is at a scrap diameter and needs to be replaced.
