Moved into Rental Flat: Cracked window panes

[chartrez]

Just moved in to a new flat. It's a listed building, 18th century. The sash windows are single glazed. They're not in the best of state of repair. Slightly rotten/ paint falling off/ pull system not attached.

One of the windows has several panes of glasses with cracks in them. You can feel a breeze coming through.

Would the landlord be obligated to fix this? With winter coming up, and single glazing, we want to minimise heat losses. We are scared to open the window in this heat, incase it smashes. It will be disruptive, as there is no access to the window from the street level, even with a cherry picker.

Did you see the broken windows before you moved in? Even so, yes he should replace them. Insist on it. Have you a copy of the Energy performance rating for the house? Obviously any draughts coming through will invalidate this. Point it out to him as you wont be getting what you've paid for.

Did you take photos & report them the day you moved in? Is it through an agency?

Even if fixed, single glazing is chilly. You can get a secondary glazing film that is easy to fix and that does cut some draughty air out, I remember having it put on each winter as a teen in an older house with sash windows.

Once the glass is fixed, you can fill gaps with folded up newspaper and tape the windows up with masking tape and then apply some window film to make a false sort of double glazing. It works pretty well. Might damage the paintwork on the windows but it sounds like this would be too much of an issue? We got some from b and q a few years back. I think it is called double glazing window film.
