Yesterday discovered a fault in our heat pump system (installed august last year)
It had been making a gurgling noise, so I checked the pressure, it was low so I filled it.
noticed it was low because of a slow leak
Called octopus today, an engineer arrived on site a few hours later
One compression joint needed tightening
Annoying to have a fault, but it's a bit of the plumbing that could have failed on any new system
Very happy with the after care from octopus
