Have you seen the advert about home insurance featuring a massive stuffed green dinosaur lately? If you have yet to do so then you are missing out because it is slightly amusing but, at the same time, holds a very real point that you need to be aware of. The home insurance company putting the ad on TV is making the point that your belongings constantly change but your home contents policy does not. As such, the amount you are insured for may not cover your stuff if anything ever happens.
So what should you do? There is an easy solution. Keep an inventory and update it whenever you buy something new, complete with the price so you know exactly what you have an exactly how much it is worth. You never know when this will come in handy but if you ever need it, it will be there and if you find that your policy no longer covers all of it then you can easily change it.
