We moved into the house in the middle of a heatwave, there was a ceiling fan in the conservatory that wouldn't come on. Then in the middle of winter in randomly came on. It was temperamental, but we soon worked out that as long as we didn't use the wall switch to turn the light on, (had a pull cord on the light) the fan would remain working. We replaced the conservatory and no longer have the fan.
There is some dodgy looking electrics in places, we have outside lights that are sensor controlled but we have absolutely no idea how they work or where the power source comes from, there are two external plugs and we have no idea what they are for. (Not the lights)
Door handle to the bedroom is quite stiff and makes a loud noise when you use it, not so great for night trips to the bathroom.
There is likely some dodgy floor boards, but not going there.
We discovered an urgent need for some repointing, this has gone from a small section that was quite bad, to the whole house being done, to the whole roof being replaced as well. At this very moment in time I am roofless.
I will need a long lie down after this to recover.
The next thing will be a full electric overhaul, there are lots of dodgy things that need looking at.
Toilet seats have been an issue here too, never fit quite right.
