Condensation on most Windows - Picture Inside

[Solus]

I know others have posted regarding UPVC windows and dehumidifiers lately, but I just wanted to know if this level of condensation is normal:

Spoiler

That's in our bedroom which is the worst culprit. The windows are 25 year old and all of that condensation you see there is on the inside.

Other windows have condensation but usually just at the bottom, you can't even see out of this!

Do you think there's something going wrong here with the seals?

I have the money to replace all the Windows but obviously don't want to do it if it's likely to be the same afterwards.

I've got extractor fans, vents and am yet to buy a dehumidifier. The house isn't boiling, it's kept at a steady 20c.

Yes, when I say inside I mean inside the house, not the pane.

So it does actually drip down on to the window sill and can be wiped off from the inside.

I've got a local upvc coming to measure up and for a quote.

I guess it's worthwhile replacing them all anyway as they are so old and will add to the look of the house.

To be honest, my little 1 year old has baths every night, obviously not steaming hot but while the water's running the door is open.

Showers are always closed doored, we've had a full rewire since buying the house (it's an old 1950s council house). Brand new extractor fan in bathroom with the overrun once light is turned off. There's a vent also in 2 adjacent bedrooms but no vent in our bedroom (it was built this way).

I also leave the ceiling fan on low in the room during the night which I read can help but doesn't.

I'm going to take the plunge and change all the windows, as previous poster said it's a big security upgrade too, my brother in law also mentioned how easy they are to break in to.

We never use the radiators to dry clothes, never have, tumble dryer is on constantly which is vented through an external wall in an outbuilding.

I've bought a 400w flood light from wickes and am going in the loft to sift through all the loose (not rolls) insulation.

It needs more insulation anyway as there's only 10cm up there.
