It’s always daunting leaving home.
You will have to pay for;
Rent
Food shopping & household stuff like washing powder etc
Council Tax (you should be able to find out online how much that is for the area you are looking at)
Water rates
Gas
Electric
Internet
Mobile phone
I wouldn’t bother with a TV licence, I’d get Netflix subscription instead
Fuel/mot/tax
You might need to pay for a parking permit if your property doesn’t have parking which can be ££
I’d always recommend trying to save a little each month for a rainy day, even if it’s just £20 you pop in a savings account each month. It does add up and it’s a small safety net
Have you thought about furniture? Sofa, bed, TV , wardrobe?
Some properties will come with white goods such as fridge, washing machine but if your new home doesn’t, you will need to buy them too.
If you need Towels, bedding, plates, glasses or saucepans Wilko are very reasonably priced.
Can you cook? If not you need to learn. Batch cooking and freezing is the best option when living as a single person. Things like jacket potatoes, stir frys, omelettes are good options too.
Yes it should be just about doable on your wage and sounds like you’d be happy away from your family home.
