Could it be the tank in the loft has a stuck ball valve which isn't letting
any water in?
If you can get at it and have a look that might show something. If it is,
then a little nudge might free it. but keep an eye on it to make sure it
stops ! Check where your main stop tap is !!
Perhaps the pipes etc. will fill up when you run a tap (and let the air out)

After using a lot of hot water, the pipes have run dry. There was a
gurgle and then a hiss like air being sucked in - then the hot water
went off.

The hot tap works in the kitchen downstairs, it's just the bathroom
taps that don't.

I left them alone for an hour or two then turned the sink tap on
again. There was a weak flow of water then it went off. Same with the
bath.

I don't have a hosepipe to try the trick of forcing water up from the
kitchen cold tap, nor do I have any plumber's tools.

Any suggestions, other than call a plumber?
