Recently moved house & thought I could smell gas under the stairs. Called the gas people & there is a very small leak but it's not their end of the meter annoyingly. Got a gas person out & he says it must be under the kitchen floor as the exposed pipes are ok.
There are two options, pull up the floor. It's tiles & I'm not sure what's underneath, I suspect concrete.
Or have new pipes put in & run them up the wall along the ceiling to the boiler.
Are they any other options? should the pipes be boxed in?
In a few years we want to do an extension & the boiler would be moved anyway so want the cheapest & quickest option really.
Is this a question for @pigletjohn?
