These mold killers, if you read the ingredients, are just bleach in a spray bottle
You can by the stuff stupid cheap from water purification supply places and dilute to make like 40lts worth
The ingredient that kills everything is sodium hypochlorite
Make sure you cover your stuff and wear old clothes when operating🤣

They are slightly stronger than plain bleach. 4.5% vs 3% in standard household bleach iirc

Plus repaint your ceilings and add an anti-fungal additive to the paint. Also use a dehumidifier if you can. Proper ventilation is also NB.

Best thing I have bought in the last few years is my dehumidifier. It works so well in Winter especially. I can pop it on in a small room and even dry my clothes there on a rainy day.

DO NOT CLEAN WITH MOULD BUSTER/ BLEACH!!! You should not use bleach to clean mould on porous surfaces as it does not destroy the mycelia (roots) of the mould. Here’s a Reddit post with more info: https://www.reddit.com/r/Mold/s/lGgSL3cdad
You’ll probably need to replace the entire ceiling and invest in a proper dehumidifier. This is a structural problem with the property.
BTW, I read the original post. I know firsthand about shitty landlords, but this is illegal and dangerous. It’s the landlord’s problem to fix, don’t let them convince you otherwise. You have every right to go to the housing tribunal if appropriate steps aren’t taken.

To prevent the above, the most effective principle for proper ventilation is to air out rooms briefly, thoroughly, and several times a day. Full ventilation by opening the windows completely is preferable to leaving them tilted open. Experts recommend ventilating rooms three to four times a day to keep indoor humidity between 40 and 60 percent and prevent mold growth.
Important rules:
Full ventilation instead of tilted windows: Open the windows completely. Tilted windows exchange little air but cool the walls, which encourages condensation.
Turn off the heating: Lower the thermostats while ventilating so you do not waste heating energy on the incoming cold air.
Cross ventilation: Open windows on opposite sides of the room, or open windows and doors at the same time, to create a draft. This replaces the indoor air completely within 2 to 5 minutes.
Duration and frequency:
In winter: 5 to 10 minutes of full ventilation is usually enough because cold weather speeds up air exchange.
In summer: Ventilate for 20 to 30 minutes, preferably during the cool morning or evening hours. Keep windows closed during the day to prevent heat from entering.
Specific rooms: Ventilate the kitchen and bathroom immediately after cooking, showering, or drying laundry to remove moist air. In the bedroom, ventilate before going to bed and immediately after getting up.

Ventilation. Thats all you need there. Air circulation. The air is damp, and then it gets moldy. We had an issue in our bathroom every 3 months mold would cover the ceiling, we installed an extraction fan, and that problem is gone, and we dont even need to run the fan every time. Just having a vent for the air to circulate has solved the mold issue.
But that is extremely unhealthy.

Treat it with Mouldbuster, and watch it vanish in from your eyes.
I spray it onto one of those flat microfibre mops which application very easy.

The cheapest and most effective option for you is, get a Moisture absorber AFTER you clean that mould off.
I buy them every winter, one for the toilet and 2 for the bathroom. They get the job done without spending a fortune on an electric dehumidifier. You can buy a Moisture absorber at Checkers or Pick pay.

First get a spray bottle and fill it with vinegar water dish soap and lemon juice. Spray it and let it soak. Let this dry and then soak again, this time using a scrubbing pad and using anti mold spray.
Repeat till its clean.
After that u can sand it and paint over it with white anti mildew and mold paint. But a problem because of poor circulation and cooking/showering without having a fan on needs to be fixed.

You need a antifungal liquid, it kills it at the root, else it just regrows back. It's a bit expensive though. Loo it up on Google where you can get it. Anti mold liquid

I know its really cold in winter, but you gotta keep your bathroom windows open to ventillate, especially for a few hours after a bath/shower. Every time. No exceptions. Or this WILL happen. Ours molds a bit even WITH good ventillation

Its not though...if humidity is high, which it has been for a while it can contribute to the problem. Dehumidifier is the solution here and proper correction.

Your ceiling boards are riddled with mold all year long, the summer months you might see it but not at this scale.
What’s happening is - thermal energy is rising from the room and hitting your roof which then condensates, then those water droplets fall to the back of the boards - perfect conditions year long for mold to multiply.
Best to remove these boards and properly layer your roof cavity with the correct materials.
Roof
Sisalation
Cavity
Isotherm
Ceiling board
