I woke this morning and started walking down the stairs, at the very bottom steps I could smell a weird smell very faintly. I turned into the living room and the same smell was in there but much stronger. I walked back out into the hallway, and could smell it but only faint like when I came down the stairs. I went into the kitchen, no smell. Went into the dining room, no smell. It's only in the living room and it's quite strong.
It almost has a bleachy smell to it, and every time I sniff up it sort of stings my nose and I can taste it (I hope that makes sense). Nobody else is awake so can't ask their opinion.
I'm a little bit paranoid because British gas was around tinkering with the gas and electric cupboards. But surely If it was a gas leak it would smell in more than one room?
Help!
