Chattanooga is the rare US metro where the cheapest fiber option is also the fastest. EPB Fiber, owned by the city's electric utility, passes every address with symmetric gigabit and tops out at 25 Gbps. That changes the negotiation. You're not picking between two cable companies and a slow ILEC. You have a municipal fiber operator that sets a price floor AT&T and Comcast cannot match on broadband. The catch is that EPB does not bid the same way on dedicated internet with hard SLAs, so the buying decision splits cleanly between best-effort fiber and DIA.
Chattanooga is one of the cheapest fiber markets in the country. EPB Fiber, the city-owned utility, has covered the entire metro with fiber since 2010 and was the first US city to offer 1 Gbps to every address. AT&T Business Fiber and Comcast Business compete for commercial accounts, but EPB sets the price floor.
The pricing problem in Chattanooga is paying AT&T or Comcast prices when EPB sits in the same building. Most small businesses default to the incumbent without checking the muni option.
What sets Chattanooga apart
Chattanooga's commercial activity sits in three places. Downtown Chattanooga holds the legal, financial, and government corridor at the heart of the metro. The Innovation District concentrates the metro's tech, startup, and small-business cluster around the Edney center. The Southside is the renovated industrial-loft creative office and small-industrial spine south of Main Street. Volkswagen Chattanooga and BlueCross BlueShield of Tennessee are two of the largest commercial accounts in the metro and shape enterprise telecom demand here.
EPB's community-wide 25 Gig service launched in August 2022, making Chattanooga the first US city with a metro-wide 25 Gbps tier available to every residential and commercial address. EPB reaffirmed that footprint in a December 2023 board update. One pricing wrinkle worth knowing: the Downtown Chattanooga business improvement district is funded by a self-imposed assessment on properties inside the district, which can be passed through in commercial leases.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Chattanooga dedicated internet, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes. Shown as a metro-tier band where city-level data is thin.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $1,060/mo | n = 6 |
| 500 Mbps | $955 – $1,660/mo | n = 6 |
| 1 Gbps | $1,195 – $2,000/mo | n = 7 |
| 10 Gbps | $1,560 – $6,250/mo | n = 6 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor EPB Fiber Business at 1 Gbps, expect $80 to $130 a month for a single office, which is among the cheapest in the country. For Comcast Business coax at 600 Mbps, the fair price is $150 to $230 a month.
Carriers worth quoting in Chattanooga
Five carriers cover most addresses in the metro.
- EPB Fiber Business. Municipal fiber, often the cheapest option in the metro.
- AT&T Business Fiber. Strong commercial fiber footprint downtown.
- Comcast Business. Coax everywhere, fiber in select buildings.
- T-Mobile Business Internet. $85 a month for 200 to 300 Mbps. Useful benchmark.
- Verizon 5G Business Internet. $99 a month at 400 Mbps.
If you have not had three of these on a quote sheet, you have not run a real comparison.

Carriers worth a quote here
- EPB Fiber Optics
Municipal fiber covering every address inside the EPB electric service territory, which includes all of Chattanooga and parts of the surrounding counties. Pricing is the same whether you're downtown, in the Innovation District, or on the Southside. Business gigabit runs well below what AT&T or Comcast will quote in the same building.
- AT&T Business
AT&T is the ILEC and has fiber in most downtown and Southside buildings, plus the suburban office parks along Lee Highway and Gunbarrel Road. They are the default DIA option for SLA-backed circuits. They rarely match EPB on price for best-effort fiber and don't try.
- Comcast Business
Strong coax footprint across the metro and growing fiber presence in commercial corridors. Comcast competes on broadband with bundled VoIP and managed services. In Chattanooga specifically, they're squeezed by EPB on price and tend to lead with multi-product bundles rather than headline circuit rates.
- Lumen Business
Lumen sells DIA, waves, and dark fiber to mid-market and enterprise accounts, mostly downtown and along the I-75 corridor. They're hungry for business right now and worth quoting against AT&T for 1G and 10G DIA. Off-net buildings carry a build cost.
- Crown Castle Fiber
On-net in selected commercial buildings, mostly downtown and near the major hospital campuses. Best fit for mid-market customers buying dark fiber or waves for multi-site or data center connectivity. Not a retail SMB play.
- Spectrum Business
Charter's footprint in this metro is lighter than Comcast's but covers parts of the outer suburbs and Hamilton County edges where EPB and Comcast both thin out. Pricing is typical Spectrum cable, with the usual modem rental and bundle adds on the invoice.

Chattanooga, Tennessee market notes
Common questions about business internet in Chattanooga, Tennessee
Is EPB Fiber actually cheaper than AT&T or Comcast for business?
Yes, for best-effort fiber. EPB Business 1 Gbps runs $80 to $130 a month at a single office. AT&T Business Fiber and Comcast Business at the same speed typically quote $200 to $400 before negotiation. EPB does not offer the same enterprise DIA product with hard SLA credits, so for mission-critical circuits you still compare against AT&T and Lumen.
Can my business get EPB Fiber if we're outside Chattanooga city limits?
Only if you're inside EPB's electric service territory. That covers most of Hamilton County and small parts of adjacent counties, but not all of them. If EPB doesn't deliver your electricity, they can't deliver your fiber. Check the EPB service map before assuming the muni option is available at a new location.
Do I need DIA in Chattanooga or is EPB Fiber enough?
It depends on what you run. EPB Fiber is symmetric and reliable enough for most small offices, including VoIP and cloud apps. If you need a contractual SLA with credits, deterministic latency for finance or healthcare workloads, or guaranteed bandwidth that won't be shared, buy DIA from AT&T or Lumen. For everyone else, EPB at a third of the price is the right answer.
Who provides redundancy if I already have EPB Fiber?
AT&T Business Fiber is the most common second circuit, with Comcast Business coax as the lower-cost option. Verify physical diversity, separate building entrances and separate conduits, not just two different carrier names. In some downtown buildings, multiple carriers ride the same entrance fiber and a single backhoe takes both down.
What's a fair price for 1 Gbps DIA downtown?
For a 36-month term in an on-net downtown building, $1,195 to $1,500 a month is the fair retail range from AT&T or Lumen. Off-net or single-tenant buildings push higher because of build costs absorbed into the MRC. If you're paying above $1,700 for on-net 1 Gbps DIA, you're overpaying and have room to renegotiate.
How do I get out of an auto-renewed AT&T or Comcast contract?
Read the notice window in your contract. Most carriers require 30 to 60 days written notice before term end. If you missed the window and auto-renewed, you have two options: invoke a portability clause to move the spend to a new product or location, or negotiate a renewal at current market rates in exchange for a longer term. Pure cancellation usually triggers a 100% ETF.
