Is it a case of refunding rent that has been paid or a portion thereof, or is it rather damages and a case of the amount of liability for damages simply being calculated as a function of the amount of monthly rent due under the tenancy multiplied by the relevant liability period?
The Government's guide to the Act for tenants contains this explanation:
What will happen to my landlord if I win in court?
If the court decides that your landlord has not provided you with a home that is fit for habitation, then they can do one or both of these two things:
- they can make your landlord do the necessary works to improve your home
- they can make your landlord pay you compensation
The court will decide how much the compensation should be by looking at how long the house or flat was unfit, how bad it was and how this harmed you.
So presumably there is a calculation done when working out how much those damages may be, which could include any of the things mentioned in the question - and this may be in addition to requiring the landlord to actually fix the problems with the property.
