Boiler making noise

Hi everyone. Please listen to attached video. We moved into this house two weeks ago. It has a smart meter that was prepay with a now bust company called nabuh. It had no gas and no way to add any. I arranged a switch to sse and today it went live, two weeks of no hot water it's a valliant boiler.
They told me to switch the boiler off and on again. When I switched it back on this noise started and brown water started leaking. The pressure jumped to 3.8bar and above the red. I switched it all off and the noise stopped. I switched it all off at the mains and gas off outside as the bar pressure would not drop. Rang my landlord emergency line and they were supposed to call me back 4 hours ago. Water is pouring outside from an overflow style pipe above the gas box. Brown sludge at first and now just brown water. Even though I've switched off the boiler everywhere including the switch box, it is still making a quieter noise which is worrying me as it has no power going to it.
Help? Any ideas.

The noise is the pressure relief valve activating

Ring your landlord and tell him to get it sorted.

Have you left the filling loop open by mistake

Yes, it sounds like you have left the filling loop open.

Brown water implies a sludged up boiler which has not been maintained properly?

Do you have a current copy of the Gas Safety Certificate which needs renewing every year and has to be current and available whenever the property is tenanted.
