Ask your landlord or managing agent hun, depending on what type of property it is it will either be at his discretion or a complete no-no. For example if you live in a flat there may be a clause in his lease saying a nobody can run a business from their home or he might have to check with his mortgage company. If he agrees try and get some sort of contract drawn up that states he gives you permission to run the business from your home, as this wont be in your current tenancy agreement. He is also within his rights to ask you for a higher deposit, due to a higher chance of wear and tear on the property. Good luck x x
