I so adamantly tell interior designers to get insurance (DO NOT WORK WITHOUT IT!!!) that I also get a lot of questions about what insurance to have. I'm not an insurance professional and do not know your specific situation so I can't tell you what insurance is best for you. However, here is a primer of insurance for interior designers so you can talk to your agent about what may be best for your business.
Get as much coverage as you can, the more the better. You may think it's overkill until you need it.
A few reasons you must have insurance: protect yourself and your business, to avoid a lawsuit, computer crashes, server explosions, natural disasters, expensive furniture, if you fall off a ladder, if your wallpaper hanger falls off a ladder, if you break a $10,000 vase, if you trip and tear a painting, if you get in a car accident driving to a client's, if you get in an accident driving to your client's with thousands of dollars of accessories in the car, if a check gets stolen, if your assistant steals, if your office gets mold, you receive counterfeit currency, you lose a valuable document, you have to track a client down for payment, a client isn't satisfied with the tile they selected, your biz credit card gets stolen and maxed out.
These are just a couple of examples of the hundreds of things that could happen and require insurance.
Insurance for Interior Designers
Business Owner's Policy: A general policy. The minimum. Do not take a single step inside someone's home without it. If you work from home, your homeowner's policy may not cover business activities and business property in your home. Reasons you need it: Your computer gets stolen from the coffee shop. You trip and break your arm at a client's. You break the leg of the client's fauteuil.
Professional Liability Insurance: This type of insurance goes a step further than the Business Owner's Policy (BOP) and insures those that give services and advice. Put simply, a BOP covers physical things - bodies, houses, objects - professional liability will cover your words and advice. This is also known as E&O (errors & omissions) Insurance. Reasons you need it: The wallpaper is buckling. You made a decision to remove a wall without telling the client. You order the wrong fabric SKU.
Commercial Property Insurance: If you have a physical office look into this type of insurance. Reasons you need it: Your office burns down. Your office is vandalized. A car drives through the front of your office.
Event Insurance: Though less likely, if you hold events talk to your agent about event insurance. Reasons you need it: Someone falls at your #shelfie demonstration.
Disability & Life Insurance: Personal insurance in the case anything happens to you and you can't work. Reasons you need it: You die. (Sorry, insurance can be morbid!) You almost die and are in the hospital for 3 months.
Workman's Compensation Insurance: If you have employees this is a must-have. Reasons you need it: Your assistant breaks her leg hanging a tapestry. If you have 5+ employees the government requires it.
If you are not covered or not adequately covered, I hope I've scared you enough to call an insurance agent today. You are playing with fire without it.
