Only place I can safely put blinds in bedroom is in the pvc of window frame,

If your walls won't take plugs for the blinds very easily, the better solution is to fit a length of wood which you fit the blind to. If you fit the piece of wood in 4 or 5 places, then even if one is poor, the others will keep it on the wall when using the blind. In our old house I fitted a piece of wood like that, and one end was a tad dodgy due to old plaster so I glued that wall plug into the wall then screwed through to give it extra purchase. Didn't budge in 10 years.

The big problem with full height tilt and turn windows, and pivot windows,  are that they come inwards when opened, so blinds inside the reveal restrict opening, and defeat the purpose of the window……to be able to clean it from inside the house.

If the windows are tall enough, a fixed panel can be left above the opening bit so that blinds can be pulled up beyond the top of the opening part.  Otherwise you are stuck with the perfect fit type, which move with the window, or blinds outside of the reveal, which can interfere with curtains.

One type of window that does not have this problem is the “H Window”, though I do not know if they come in uPVC.   These have hinges that allow the window to be opened, and turned through around 180 degrees for cleaning, without coming into the reveal at all.

We used these from Amazon in a similar situation.   Tropik Home Pleated Blind

Thanks for responses, I have worked out how to open window a little now but good to know another method for when it gets warmer again in a few months,

Now I think about it I could do what is suggested above as it's similar to what I thought of, if I put some pieces of wood up and screw those into the plaster near the frame and put a bit of glue on too I can mount the blinds to them.

There are blinds that fit into the window -  if you don't have enough light already may not be an option.

Very effective for blocking light, heat, cold depending on the material you choose

Something like this

I found these, which are similar to what we have, not sure if it’s the same company as what we have, but it’s very similar

That's a smart solution for tricky walls! We've seen similar challenges in older Ponte Vedra, FL homes where plaster can be unpredictable. A few additional tips we've found helpful:

1. Wood Selection Matters:

   • Use 1x3 pine or poplar (lightweight but sturdy)

   • Pre-drill screw holes to prevent splitting

2. Alternative Mounting Options:

   • For tile/metal windows:
     Aluminum mounting channels work well

   • For really fragile walls:
     French cleat systems distribute weight evenly

3. Reinforcement Tricks:

   • A dab of construction adhesive on wall plugs adds holding power

   • Sandwiched rubber washers prevent gradual loosening

The key is distributing the blind's pull force across multiple points - your 4-5 screw approach is spot on. We've had clients use this method for heavier wood blinds and even cellular shades without issues.

I have tilt and turn windows with perfect fit blinds.  They do add a small border to the window, which after a day or two you won't notice.  One thing to check on is how much room you have to open the window fully inwards against the window reveal - roller blind styles may be too thick - something to check with the manufacturer.  The pull down cellular style don't have that issue and still are pretty good for blackout.
