Bornfiber is a regional internet service provider in Denmark that primarily serves the island of Bornholm. If you are moving to Bornholm, this company will likely be your primary point of contact for high-speed connectivity. They own and operate a significant portion of the fiber optic infrastructure on the island. While the Danish broadband market is generally open and competitive, geography dictates availability.
Expats settling on Bornholm often find that internet from Bornfiber is the default choice for a stable connection. The company focuses almost exclusively on Fiber-to-the-Home (FTTH) connections. This ensures high bandwidth and symmetrical speeds, which are essential for remote work and video conferencing. Understanding how to navigate their signup process, technical requirements, and contract terms is vital for a smooth relocation.
The Role of Bornfiber in the Danish Market
Denmark operates on a digital infrastructure model where network owners often sell access to service providers. Bornfiber is somewhat unique because it acts as both the infrastructure owner and the service provider for a specific region. Historically, they held a monopoly on the fiber connections on Bornholm.
Recently, the Danish telecommunications market has shifted toward “open networks.” Bornfiber has joined cooperation agreements, such as OpenNet. This technically allows other service providers to rent capacity on Bornfiber’s cables. Conversely, it allows Bornfiber to offer services in other parts of Denmark outside of Bornholm. However, for most expats living on the island, dealing directly with Bornfiber remains the most common scenario.
Checking Availability at Your Address
You cannot simply choose any provider you wish in Denmark without first verifying the physical infrastructure at your specific residence. This is done via an address check on the provider’s website. You enter your street name, house number, and floor.
The system queries a central database to see if a fiber cable has been dug into your property. If the result is positive, you can order service immediately. If the result is negative, you may need to pay for a technician to dig a cable from the street to your house. This is common in older houses or summer cottages that have not been renovated recently.
Requirements for Expats: CPR and MitID
Signing up for internet contracts in Denmark generally requires digital identification. This presents a “chicken and egg” problem for new arrivals who need internet to access banking and government services but need those services to get internet.
The CPR Number
You must have a Danish CPR number (Civil Registration Number) to enter into a standard subscription contract. This number tracks your creditworthiness and legal residence. If you have just arrived and do not have your yellow health card (Sundhedskort) yet, you cannot sign up online.
MitID and NemID
Online sign-ups require authentication via MitID (formerly NemID). This is Denmark’s digital ID system. If you do not have MitID yet, you cannot complete the self-service order flow on the Bornfiber website.
If you lack MitID, you must contact customer support directly via phone. You will likely need to provide alternative proof of identity, such as a passport and your lease agreement. Be prepared for a longer processing time compared to the automated digital flow.
Foreign Credit Cards and Payments
Most Danish internet providers, including Bornfiber, prefer payments via “Betalingsservice.” This is a direct debit system linked to a Danish bank account.
Foreign credit cards (Visa/Mastercard issued abroad) are frequently rejected for recurring monthly subscriptions due to 3D Secure requirements and anti-fraud measures. It is highly recommended to open a Danish bank account as soon as possible. If you must pay with a foreign card initially, expect manual invoicing fees or the need to pay bills via bank transfer (Girokort) at a convenience store or post office, which incurs extra charges.
Speeds and Pricing
Bornfiber focuses on simple, high-speed fiber tiers. Unlike DSL or cable connections where speeds fluctuate based on distance, fiber offers consistent performance. The following table outlines typical speed tiers and costs you might encounter.
| Speed Tier (Download/Upload) | Ideal For | Estimated Monthly Price (DKK) | Setup Time |
|---|---|---|---|
| 200/200 Mbit | Couples, small apartments, standard streaming. | 249 – 299 DKK | 2-4 weeks |
| 500/500 Mbit | Families, multiple devices, 4K streaming. | 319 – 369 DKK | 2-4 weeks |
| 1000/1000 Mbit (1 Gbit) | Heavy users, large households, large file transfers. | 389 – 449 DKK | 2-4 weeks |
| Summer House Plans | Vacation homes (often lower speeds or seasonal billing). | Varies significantly | 2-6 weeks |
Prices in the table are indicative and subject to change based on current campaigns. Installation fees often apply if the residence has never had fiber installed before. This “creation fee” (oprettelse) can range from 0 DKK during promotions to 2,000+ DKK if digging is required.
Latency on these connections is typically very low (below 5ms), making them excellent for VoIP calls and gaming. The symmetrical nature of the connection means your upload speed matches your download speed, which is a significant advantage over coaxial cable internet.

Hardware and Installation Process
When you order fiber internet in Denmark, the hardware setup involves two distinct pieces of equipment. Understanding the difference helps when troubleshooting or setting up your home network.
The Fiber Box (ONT)
The first device is the Optical Network Terminal (ONT), often called the “fiber box.” This is a small white box mounted permanently on the wall inside your home. It converts the light signals from the street cable into electrical signals. You must not remove this box when you move out. It belongs to the infrastructure owner (Bornfiber).
The Router
The second device is the router. Bornfiber typically includes a router with their subscription, sometimes for a small monthly rental fee or as a free loan. This router connects to the fiber box via a standard ethernet cable (RJ45).
You are generally allowed to use your own router if you prefer high-performance third-party equipment. However, Bornfiber support will only troubleshoot up to the fiber box if you use your own router. If you use their provided router, they can assist with Wi-Fi settings and diagnostics remotely.
Technician Visits
If your home is already connected to the fiber network, a technician visit is usually not required. You simply receive the router by mail, plug it into the fiber box, and wait for the activation SMS.
If the house is not connected, a technician must visit. You must be home during this appointment. They will drill a hole through the outer wall to bring the cable inside. In rental properties, you must have written permission from your landlord before authorizing any drilling.
Contract Terms and Consumer Rights
Denmark has strong consumer protection laws regarding telecommunications. These rules apply to Bornfiber and protect expats from unfair lock-in periods.
Binding Period (Bindingsperiode)
The maximum binding period for private consumers in Denmark is six months. You cannot be locked into a contract for longer than this. If a provider offers a “free installation” deal, it is almost always conditional on you staying for these six months. If you cancel early, you may be liable for the remaining months or the installation cost.
Notice Period (Opsigelsesvarsel)
After the initial binding period, the standard notice period is one month to the end of a month. This means if you cancel on January 15th, you will pay for the remainder of January and all of February. The contract ends on February 28th. Always factor this into your moving budget.
Right of Withdrawal
If you order online or over the phone, you have a 14-day right of withdrawal (fortrydelsesret). This starts from the day you receive the order confirmation. If you regret the purchase within this window, you can cancel without penalty, provided the installation has not already physically occurred.
Moving House and Transferring Service
If you move to a new address within Bornholm, you can usually transfer your Bornfiber subscription. You must notify them at least 3-4 weeks in advance to ensure the new connection is active on your move-in date.
If you move away from Bornholm to a different part of Denmark, you may have to cancel your subscription. Bornfiber has limited reach outside their home region. In this case, you will need to find a new provider. You can check general availability for home internet Denmark to see which large national providers cover your new area.
If you move to a location where Bornfiber cannot supply service, the binding period is usually waived, but you must provide proof of your new address (via the CPR register).
Summer House Internet
Bornholm is a popular destination for vacation homes (sommerhuse). Bornfiber offers specific subscriptions tailored for summer houses. These plans sometimes allow for “resting” periods where you pay a lower rate during the winter months when the house is empty.
Installing fiber in a summer house often requires more extensive digging than in a city apartment. The distance from the road to the house can be significant. Be sure to request a quote for the digging work (gravearbejde) before signing the contract.
Alternatives to Bornfiber
If you are renting a temporary room or your landlord does not permit fiber installation, you have alternatives. The most common backup is mobile broadband.
Mobile Broadband (4G/5G)
Denmark has excellent mobile network coverage. You can purchase a 4G or 5G router that requires only a power outlet. This avoids technician visits and cabling. While latency is higher than fiber, speeds are sufficient for streaming and general browsing. You can read more about mobile broadband Denmark to compare options.
Other Fiber Providers
Because Bornfiber has opened its network, you may see other companies offering service at your Bornholm address. Large national players or smaller competitors might offer different pricing structures or router hardware on the same physical cable. It is always worth performing an address check with a comparison service to see if you have a choice between providers.
Customer Support and Language
Bornfiber is a Danish company, and their primary communication is in Danish. However, most technical support staff speak English. When calling support, you may encounter a Danish voice menu (IVR). Pressing buttons randomly often routes you to a human, or you can listen for keywords like “Support” or “Teknik.”
Email correspondence is often easier for expats as it allows for the use of translation tools. Contracts and terms of service will almost invariably be in Danish. It is your responsibility to understand what you are signing.
Troubleshooting Connection Issues
Fiber connections are generally very stable. However, if you experience dropouts, the issue is frequently the Wi-Fi signal rather than the fiber line itself. Danish homes are often built with brick and concrete, which blocks Wi-Fi signals effectively.
If you live in a large house or a concrete apartment building, the single router provided by Bornfiber may not cover the entire area. You may need to invest in a Mesh Wi-Fi system. This consists of multiple units placed around the home to create a unified network. Bornfiber may sell these as an add-on, or you can buy them from electronics retailers.
Always check the lights on your ONT (fiber box) before calling support. If the “Power” and “Fiber” (or “WAN”) lights are green, the connection to your house is working. If the “Fiber” light is red or off, the physical line is broken, and a technician is required.
