If the commercial property is under a certain sq ft then you get 50% relief, this is topped up to 100% by the government.
If you are over a certain sq ft, you will get a discount but unsure as to how much, then that percentage alter depending on the area until no discount is given
For example a property is over 4000 gets no discount.
If you rent out a room to another business, that area can be removed from your amount and you might fall lower into a discounted bracket, the person renting the room will be classed as another business and ve charged, but will get full relief because it's just a small room.
We have a sign shop and certain areas are charged or added up differently, showroom is the highest rated, work areas and storage at different rates.
