Right, turned off everything on consumer unit, noise still there.
- could be plumbing/HW cylinder? (It is a constant high pitch whine that is there regardless of if CH/HW is on or not though)
- could be smoke alarms (wired, but with battery backup)
- could be boiler timer control unit downstairs (also has battery backup)
- its not bees, or aliens etc
- a bug planted by the government!
Maybe the electricity meter outside? No way to isolate that I guess.
