I live on the ground floor of a block of flats in London. I came back
to my flat from holiday and immediately noticed an unpleasant smell. I
thought at first it smelled like ripe cheese like camembert but later
I thought it smelled like sewage.

It seemed to be coming from a storage area where the gas meter is. I
removed everything in the storage area and these things do not smell.
The storage area still smells though. I don't really know what gas
smells like do I don't know if I have a gas leak. There doesn't seem
to be any dampness as far as I can see.

What should my next step be? I don't want to have to put up with the
smell forever.

Is there a floor drain in that storage closet? If so I'd try pouring
a bucket of water down it and see if the smell goes away. If you
don't, or if it does not, I'd call the gas company - certainly you
don't want to be living in an apartment with a live gas leak!
