Sliding Door anti lift device

My metal patio doors do it differently for the fixed and moving pane.

The fixed pane has a small bracket on the inside middle vertical which is screwed into the track and the concrete under it that stops it being lifted.

The moving pane has a hole in each end of the botton rail where you adjust the hight of the wheel at each end so that it cannot be lifted enough to allow the pane to get off the track enough to allow it to be swong out of the track.

I’m surprised it wasn’t required before.

In our previous house, which had sliding patio doors between the dining room and a conservatory, which had a normal door, we were required to fit anti lift devices, even though there was another internal door to the kitchen. I don’t recall exactly when this was but we moved here over 25 years ago.

One of the first things I did was to fit anti lift devices to the patio doors….

You can get several types. Some are just bits of metal which you screw into the tracks at the top.They are thin enough to allow the doors to open but not be lifted up. This stops the doors being lifted so the bottom can be pulled out.

Another uses a locking, pop out, pin. These also stop the doors sliding but require holes in the door frame. You need to remember to lock these.

In the past they have been happy with the default answer "No we haven't got these" ( Including BS 3261 locks) but this year they wanted positive confirmation that we have.

So I have had to change the lock between the garage and the house from a

Why not try changing the home insurance company?

They'll probably all be asking for it anyway. The OP can probably still get insurance sorted out, but it'll just cost a bit more I'd imagine.

I recently changed my home insurance company, reducing the premium from £420 to £250, for better coverage. No questions asked about locks or patio doors, and nothing about them in the T&Cs either.

No mention here either.
