I have a constant humming whirling noise in my house these past few weeks. It's a detached house. Obviously more evident at night when it's quieter but is present 24/7. It's all over house but louder at the front. Outside you cannot hear the noise.
I have turned off the electric mains and all individual circuits and it's still there.
open reach have been out as pole outside house but nothing detected.
checked water meter and reading no excess usage..no changes to water pressure..no changes to CH water pressure.
Been to several neighbours they don't hear anything.
Had several people in house one could hear it.
its affecting my sleep and I am at the end of my tether
What can it be?
