I currently work full time but I've had some health issues for a couple if years now and think I need to reduce my hours.

I've done a quick check on listentothetaxman and it looks like I would drop from £1100pm to about £830pm if I halve my hours. That seems too good.

Has anyone else done this?

I would say that was wrong. Try salary checker for a more accurate estimate.

Might be right due to increases in last few
years in personal tax allowances ....

I can't remember the actual amounts, but I remember being pleased about how much I still got when I went from FT to 0.6, and that was 12 years ago, the personal allowance (the first x thousand that you don't pay any tax on) has gone up a lot since then.
If you can claim tax credits, then they may increase if your income decreases too.

I used to work full time and then went to 2 days per week and I think the drop was similar to what the OP states. Something to do with tax rates that I don't understand.

I used my own calculator and I reckon it would be about £650pm unless you have a strange tax code.

If the numbers are take-home rather than gross pay they're probably correct. I did a similar calculation not so long ago and, because I'm a higher rate tax-payer and also a parent, if I halve my gross, my take-home (including CB and CTC which I don't currently get) only went down by about 25-30%

I went from five days @ 38 hrs to three days @ 25.5 hrs and was pleasantly suprised as the drop wasn't as bad as I thought.
