Making a Will is not about wealth it is about making sure that what you want to happen to your estate does happen. It gives you the opportunity to specify such things as who will administer your estate, who will care for your children and who will receive specific items of your property.
It is quite common for people to be worth more dead than alive.
Add up the totals of your life assurance policies, your death in service benefits and so on. What about your car, your house and the antique furniture your grandmother bequeathed you?
The total may well surprise you. Anyway it is your money, regardless of how small the sum, and you should be the one to say where it goes on your death.
