Utility Bill-Back Letter to Tenants: Free Template & Guide
Free template for a utility bill-back notification letter to tenants. Learn what to include, how to introduce RUBS billing, and avoid common disputes.
Why You Need a Bill-Back Notification Letter
Before you send your first RUBS utility invoice to tenants, you need to notify them about the billing program. A clear, professional notification letter sets expectations, explains the methodology, and significantly reduces the chance of disputes later.
Whether you're implementing RUBS for the first time or adding it to lease renewals, this letter is your first impression. Get it right, and most tenants will accept the charges without pushback. Get it wrong — or skip it entirely — and you'll spend more time fielding complaints than you saved on utilities.
What to Include in Your Letter
A complete bill-back notification letter covers six key elements.
The effective date. When will billing start? Give tenants at least 30 days' notice before the first invoice.
Which utilities are included. Be specific: electricity, water/sewer, gas, trash, or all of the above.
The allocation method. Explain whether you're using square footage, occupancy, a weighted blend, or different methods for different utilities. Tenants don't need a math lesson, but they need enough detail to understand why their bill is what it is.
How invoices will be delivered. Will you email them, slip them under the door, mail them? State the delivery method and timing (e.g., "Invoices will be emailed by the 5th of each month").
Payment terms. Due date, accepted payment methods, and any late fee policy.
A contact for questions. Give tenants someone to reach out to. A dedicated email address works well.

Date: [Month Day, Year]
RE: Utility Billing Program — [Property Name]
Dear [Tenant Name / Residents of Unit ___],
This letter is to inform you of a utility billing program that will take effect on [effective date]. Beginning on that date, you will receive a monthly utility invoice for your proportional share of the building's utility costs.
Utilities included: [Electricity, Water/Sewer, Gas, Trash]
How your share is calculated:
Your monthly utility charge is determined using the Ratio Utility Billing System (RUBS). This method allocates the building's total utility costs proportionally based on [your unit's square footage relative to the total occupied square footage in the building / the number of occupants in your unit relative to total building occupancy / a weighted combination of unit square footage and occupancy].
This approach is widely used in multifamily housing and ensures each household contributes fairly based on [unit size / the number of residents / both factors].
Your unit's details:
- Unit: [Unit number]
- Square footage: [X] sq ft
- Occupants: [X]
Invoice delivery and payment:
You will receive a utility invoice by [email / mail / door delivery] by the [5th] of each month for the prior month's utility costs. Payment is due by the [15th] of the month. Accepted payment methods include [check, Venmo, Zelle, online portal].
Important notes:
- Vacant units are excluded from the allocation. The property owner absorbs the cost for any unoccupied units.
- If the number of occupants in your unit changes, please notify us within 14 days so we can update the billing calculation.
- Utility invoices will include a detailed breakdown showing each utility type and the total amount due.
If you have any questions about this program, please contact us at [email address] or [phone number].
Thank you for your cooperation.
Sincerely, [Your Name] [Title / Company]
Tips for a Smooth Rollout
Time it with lease renewals. The cleanest way to implement RUBS is when tenants sign new or renewed leases. Include a utility billing addendum in the lease that references the RUBS methodology.
Start with one utility. If you're nervous about tenant pushback, start by billing back just water (which is easy for tenants to understand — more people equals more water). Add other utilities once tenants are comfortable with the process.
Be transparent about the math. Include the allocation percentage and formula on every invoice. When tenants can verify the math themselves, trust goes up and disputes go down.
Show the total building bill. Some landlords include the total utility bill amount on each tenant's invoice so they can see they're only paying their proportional share, not a markup.
Keep records. Save copies of the master utility bills, your calculations, and all invoices. If a tenant questions a charge, you want to be able to pull up the documentation immediately.
Handling Tenant Questions
The three most common questions you'll get:
"Why is my bill higher than my neighbor's?" Point to the allocation factors: different square footage or different number of occupants means different shares. The formula treats everyone the same.
"How do I know you're not marking up the bills?" Offer to show the master utility bill. The total of all tenant invoices should match (or be less than) the total building bill. The difference, if any, is the owner's share for common areas and vacant units.
"Can I opt out?" If RUBS is part of the lease, it's not optional. But frame it positively: utility billing is common in most rental housing, and it incentivizes conservation which benefits everyone in the building.
Automating the Process
Writing individual letters and calculating shares manually works for a few units, but it gets old fast. BillBack lets you set up your property once, enter the monthly utility bills, and generate professional invoices for every tenant in seconds. You can email invoices directly to tenants and track who's paid.
