Roommate Utility Deposits: Who Pays and How to Split Them Fairly in 2026
Utility deposits can catch roommates off guard. Here's how to handle setup fees, security deposits for water/electric, and split costs fairly from day one.
The Hidden Cost of Moving In
When you move into a shared home, rent isn't the only upfront cost. Most utility providers — electricity, gas, water, internet — require deposits, especially if no one in the household has an established account history. These can range from €50 to €300 per service, and they add up fast.
Who Should Pay the Utility Deposit?
The fairest approach is to split utility deposits equally among all roommates, since everyone benefits from the services. However, if one person's name is on the account, they may need to front the deposit. Keep a clear record of who paid what and agree on how refunds will be distributed when the deposit is returned.
Tracking Deposits with HomeCo
Instead of messy spreadsheets or group chat arguments, use HomeCo's expense tracking to log every utility deposit, who paid it, and the expected refund timeline. When the deposit comes back, the app reminds everyone to settle up.
What Happens When a Roommate Moves Out?
If a roommate leaves mid-lease, the utility deposit situation gets complicated. The departing roommate should receive their share of the deposit back, either from the incoming replacement or from the refund when it arrives. Document this in your roommate agreement to avoid disputes.
