Don't forget to insure your household contents. That way you avoid unpleasant surprises in case of fire/water damage, burglary and theft.

Content insurance not only covers damage to the things in your room(s), but also, for example, damage to things in your garden or storage room. You can get insurance through your parents' insurance, through your bank and often also through your (health) insurance company. Such insurance is not expensive but important in case of e.g. fire or theft. Contents insurance is also often part of a package with other insurances.

A useful site for all kinds of insurance and insurers is Choice.co.uk. With household contents insurance, you can often also take out liability insurance. Such insurance covers damage to property (material damage) and people (personal injury) that you accidentally cause. Get informed about this.
