Help! Can I cut down flashing or UPVC window?

[SJRSJR]

Help please!

I was happy to replace a window that my roofers wanted to remove and used their dimensions for the replacement. I did check it at the time but wasn’t aware that they would be doing the lead work as in the photo. Now the window won’t fit!

I could cut the rims down but it'll still be so tight that it'll be a struggle. And even if it did fit won’t the lead create a cold bridge between inside and out?

Should it/can the lead be cut away too, and if so, to where? If it were to butt up to the frame on the outside wouldn’t that mean the sealant would be the only barrier to the timber frame?

Any advice as to a solution before I resort to buying a new window? Thanks

And my next question is, if I got a new frame reduced by 10mm all round, would there be any chance that the glazing units of the first one might still fit the second one? Thanks

if the dimensions were ok before the lead was added, cant you just taken enough off for the window to fit?

I mean the window shouldve been 10mm smaller tan the structural opening anyay, so it should almost have fitted

I can see theyve done soakers so youve ended up with double thickness lead each side

usually the legs on the outside of a upvc window are reasonably far back to take quite a few mms off each side

no is the short or long answer!

Thanks. Noted

The window supplier has suggested cutting the legs too but the technical department of the profiler (Liniar) say I need to allow for expansion and contraction and airflow. It's west facing and cutting the legs would mean it's tight in!
