The short answer
Fibrus is a full fibre provider in Northern Ireland and rural Cumbria, and how your installation works depends on which network reaches your address. On Fibrus's own network, an engineer brings a fibre cable to your home, fits a small wall-mounted box called an ONT (optical network terminal, the box the fibre plugs into) and connects your router; Fibrus says the service is live the same day. In some areas Fibrus sells broadband over Openreach's full fibre network instead: the kit is posted, and if your home already has an Openreach ONT, the service is switched on remotely.
Standard installations are free; work beyond Fibrus's standard routes can cost extra. This guide draws on archived copies of Fibrus's help pages saved between May and September 2026 (a save date shows when a page was copied, not when its text was written) and on its terms and guides dated May 2025 to July 2026. None of them describes a different installation process for Northern Ireland and Cumbria. Fibrus has since launched a new support centre, so check the current pages too.

Fibrus's network or Openreach's: which installation you'll get
Fibrus builds its own full fibre network, also called FTTP (fibre to the premises): its terms describe the fibre running directly to the property from the nearest street cabinet. In Northern Ireland that network includes the government-funded Project Stratum build; our guide to broadband roll-out plans in Scotland and Northern Ireland explains how to check whether funded fibre has reached your address. Since April 2025 Fibrus Group has been organised as three businesses: Fibrus Broadband, the retail brand you buy from; Hyperfast Networks, which operates and maintains the network; and Viberoptix.
ISPreview reported in February 2024 that Fibrus planned to sell broadband over Openreach's network outside its own areas, and its 2026 offer terms refer to "Off-net postcodes" on its postcode checker. So checking your address also tells you which route applies:
Your address | How the equipment arrives | Engineer visit? |
|---|---|---|
Fibrus Network area | The installer brings it on the day | Yes: a new cable and ONT are fitted |
Openreach Network area, Openreach ONT already fitted | Royal Mail, up to 6 days before activation | No: Fibrus activates the service remotely ("Self-Install") |
Openreach Network area, no ONT | Royal Mail, up to 6 days before the installation date | An Openreach engineer visit, which Fibrus emails you about |

From order to installation day
You order by checking your postcode, choosing a package and giving your contact and Direct Debit details. Fibrus then sends two emails: one confirming the order, and one with your survey or installation date. Fibrus's planning team confirms the date once any checks are complete. Where a property is far from the road or has access problems, a surveyor is likely to visit first to agree the route, and extra poles or digging may be done beforehand, which Fibrus warns can cause delays. If so, ask whether the route counts as standard (free) or non-standard (charged).
The help pages we used didn't give a typical wait, slot length or visit length. Fibrus's newer support centre (archived September 2026) lists a "Your installation day" article covering who needs to be present and how long the appointment takes, so read that or ask when you order. Our guide to broadband installation lead times explains what affects waits.
Who can order, and what renters need
Fibrus's residential terms (for contracts starting on or after 1 May 2025) say that by ordering you confirm you're at least 18 and either the owner-occupier or a tenant with legally binding permission from the owner to install Fibrus's equipment. Because the engineer drills through an outside wall and fixes a box inside, get your landlord's permission in writing before you order. Our guide to broadband for renters covers what to ask for.
Changing or cancelling the appointment
Fibrus's terms ask for at least two working days' notice to change or cancel an installation appointment, or it may charge a missed appointment fee (the amount is in its price guide). Fibrus's installation page gives 028 9099 3230, its Northern Ireland number, for rescheduling; its contact page lists 080 0099 1111 for customers in Great Britain. Fibrus says leaving it too close to the date may mean rescheduling isn't available.
Getting your home ready
Fibrus's installation pages ask for the following.
- Power sockets close together. At least two standard UK (type G) sockets near each other: one for the mains-powered ONT and one for the main eero router, plus a third for the Fibrus Talk phone adapter if you take Talk.
- A view on where the cable comes in. The ONT and router need to be close together, so the entry point you agree largely decides where your main router lives.
- Someone over 18 at home for the whole slot, and a few hours after, who can agree the cable route and router position and sign off the work; the extra hours cover an engineer arriving late in the slot.
- Pets kept away for the staff's safety.
- A smartphone, ideally, to set up the eero through the eero app; without one, the engineer uses an alternative set-up method.
- A plan for wired devices. The eero has one spare Ethernet port (used by the Talk adapter if you have Talk); Fibrus suggests a 5-port Ethernet switch for more.
For more on the box itself, see our guide to the ONT and your router.
On the day: installation on Fibrus's own network
Putting the steps on Fibrus's installation page in the order they happen on the day:
- Arrival within your confirmed slot, with all the equipment.
- Agreeing the route. Fibrus tries to follow your existing cable route: overhead from a nearby telegraph pole, or underground through a duct (a buried pipe) if it's usable. A blocked duct may be dug out and everything put back; with no existing route, extra infrastructure may be needed.
- Outside cable and a small hole to bring the fibre inside.
- The ONT is fixed to an inside wall and plugged into power, then connected by Ethernet to the main eero router where you've agreed.
- Testing. The engineer runs a speed test from one of your devices and shows you how to connect and where to find the Wi-Fi password.
- Walk-through and sign-off if you're happy with the work.
Fibrus aims to install and activate in one appointment, though non-standard work or unexpected problems can mean more visits. Any digging is reinstated to a high standard, though surface coatings may differ slightly, and its terms say it will repair damage it causes at your home; see our guide to damage to your home during an installation.
Standard and non-standard installations
Fibrus's home page lists "No install or set-up fee", and its December 2025 price guide says there are no connection fees or installation costs for standard installations. The important word is standard. Fibrus's terms define it as the most expedient route under its normal commercial criteria, chosen by Fibrus beforehand:
- overhead, via telegraph poles;
- a new underground duct laid by Fibrus; or
- your existing underground duct, if it's suitable without repair, replacement or add-on work.
Its Non-Standard Installations and Self-Build terms (May 2025) give examples of work that is charged:
Situation | What Fibrus's terms say |
|---|---|
Your existing duct needs repairing, replacing or adding to | Non-standard, so charged |
You turn down the free standard installation (for illustration: you'd rather have an underground route than an overhead one) | Charged (for example, laying new underground duct and cable). The site survey fee is not credited against the work. |
A network extension Fibrus wouldn't otherwise build | Charged, but Fibrus contributes 50% (excluding VAT), up to a cap; it contributes to no other non-standard work |
New-build plots and multi-property developments | Charged |
Fibrus gives a quote, and you pay the difference between its cost of a standard installation and the non-standard work in full before work starts. You must give access and get any consents needed, including for Fibrus to cross land (see our guide to broadband wayleaves).
Survey fees, group projects and self-build
Non-standard work may need a site survey first, with an upfront fee. It's refunded in full if Fibrus cancels and doesn't rebook, or if you cancel with at least 24 business hours' notice (business hours are 8am to 6pm on weekdays). Fibrus keeps half if you cancel or rebook with more than 4 but less than 24 business hours' notice, and refunds nothing with less than 4 business hours' notice (even if the survey is rebooked), if the surveyor can't get access, or in any other case. Unless you turned down the free standard installation, the fee is credited against the cost of the work.
You can cancel the work before it starts (an administration charge comes off your refund with less than 24 business hours' notice); after it starts, you pay for work done or committed to. Two other routes are in the terms. Neighbours can join as a group project, with the cost split between households and an appointed representative paying the survey fee. Or you can part self-build, laying duct within your own boundary at your own expense to Fibrus's specification; Fibrus supplies reasonable amounts of duct but can charge for extra duct and cable over a standard distance. For blocked ducts in general, see what happens when a duct is blocked.
Openreach areas: posted kit and remote activation
If your address is in one of Fibrus's Openreach Network areas, your equipment arrives by Royal Mail up to 6 days before the installation or activation date. Delivery changes are arranged directly with Royal Mail. Fibrus then emails to say either that you're eligible for "Self-Install" or, where there's no Openreach ONT yet, that an Openreach engineer is scheduled to visit. Fibrus doesn't describe that visit; our guide to what to expect at a full fibre installation covers how such visits generally run.
If your home already has an Openreach ONT
If your home already has an Openreach ONT, Fibrus uses it and activates your service remotely, with no engineer:
- Notice: at least 14 days' warning of the remote activation date.
- Openreach check: Openreach gets in touch to make sure the ONT is working, plugged in and powered on, and confirms on the day that the service is active.
- Swap the router: unplug your old provider's router from the ONT and connect the Fibrus eero. Fibrus doesn't remove the old provider's equipment.
- Set up the eero using the Installation Leaflet in the box or the video at fibrus.com/eerosetup.
- Confirmation: Fibrus emails when the service and your account are live.
For general tips, see our guide to self-installing broadband.
Setting up and placing the eero routers
Fibrus supplies Amazon eero routers. eero is a mesh Wi-Fi system (several units link together to spread Wi-Fi around a home), which is why bigger packages come with two. Fibrus's documents of different dates list:
Package | Routers supplied | Where it's listed |
|---|---|---|
Full Fibre Essential and Full Fibre 100 | One eero 6+ | October 2025 Products and Services Guide |
Full Fibre 150 | One eero 6+ | Summer 2026 offer terms |
Full Fibre 300 | Two eero 6+ | May 2026 help page |
Full Fibre 500 | Two eero 6+ | October 2025 guide; summer 2026 offer terms |
Full Fibre 1000 and 2000 | Two eero Pro 6E | October 2025 guide |
Its December 2025 price guide lists Full Fibre 300 and 2000 in select areas only, and its September 2026 support menu also covers Nokia routers, so check which router your package includes.
Fibrus's placement advice: keep the eero on show and up high, away from windows, the back of the TV and metal objects, with as few walls as possible between it and where you use Wi-Fi, and don't tightly wind the cables. For large homes it suggests a package with its Total Home Wi-Fi Guarantee. See also mesh Wi-Fi versus Wi-Fi extenders.
The Total Home Wi-Fi Guarantee
Some Fibrus packages come with a Total Home Wi-Fi Guarantee: at least 10Mbps download speed in every eligible room. Fibrus's September 2026 home page says it applies on Full Fibre 500 and above, as does its October 2025 guide; its December 2025 price guide labels Full Fibre 500, 1000 and 2000 with the guarantee, and a May 2026 help page also included Full Fibre 300. Its Summer Sale 2026 terms (an offer that ran from 20 May to 13 July 2026) marked Full Fibre 150 as not including it. Confirm it's included before you order.
How a claim works: Fibrus troubleshoots first, including eero placement, then provides up to one extra eero free; if three eeros still don't reach 10Mbps, you must agree to an engineer visit. If it still can't be achieved, you can cancel without early termination fees, provided you've followed Fibrus's reasonable instructions, but you still pay for the broadband up to cancellation and for any non-standard installation work. The help page says you can cancel "30 days after the last service contact"; the October 2025 guide and summer 2026 offer terms say within 30 days of the engineer's visit.
Which homes qualify: up to five bedrooms and three reception rooms, no more than 3,000 sq ft, main house only, no basements or rooms below street level, and no structural changes since purchase. There's no money compensation, and no more than three routers under the guarantee. Our guide to what provider Wi-Fi guarantees actually promise compares the schemes.
Switching to Fibrus without losing service
Fibrus's home page says it uses One Touch Switch, Ofcom's switching process, which went live on 12 September 2024 (as reported by ISPreview). Under it you contact only Fibrus; your current provider must send you the switching information, including any early termination charges; and you don't cancel your current broadband yourself, because Fibrus arranges the switch with your old provider and the old service stops when the switch completes. Fibrus says you're usually without service for no more than one working day. One Touch Switch is for switching at the same address; if you're moving, see broadband when moving home.
Fibrus's terms also recommend not ending any existing broadband or phone service until the Fibrus installation is complete and activated, which matters for anything you arrange yourself outside One Touch Switch. If something goes wrong, see broadband switching problems.
Keeping your phone number with Fibrus Talk
Fibrus Talk, the home phone service, runs over broadband through an adapter plugged into the eero. You can transfer your number free (you may need to sign a Letter of Authority). Fibrus's Talk and switching pages (archived in May and June 2026) describe the number moving as a separate step after your broadband goes live: 7 to 12 working days from installation on one, about 14 days after activation on the other. Ask when you order whether your number moves with the switch or afterwards, and keep the old line active until Fibrus confirms the transfer.
Two warnings before you rely on Talk for calls. First, Fibrus's terms say alarms and healthcare devices that rely on a copper landline (home security, burglar and personal alarms included) aren't supported, so they need replacing or upgrading unless you keep a copper line. Second, neither the broadband nor Talk works in a power cut: Fibrus suggests a mobile and offers an emergency call divert, and if you rely on your landline, your mobile signal is unreliable or you have particular personal circumstances, you may qualify for a Battery Backup Unit. It keeps the phone working for at least 60 minutes in a power cut (unless the network is also down) with a corded phone, not a DECT cordless one. If anyone relies on a telecare alarm, read telecare alarms and the digital landline too.
Help with exit fees
Fibrus's Contract Buy Out scheme (terms dated July 2026) contributes towards an early termination fee from your current provider, up to a maximum that varies by postcode. It's for new customers, or returning customers whose household has had a break of at least 3 months from Fibrus. You need a Fibrus contract of 18 months or more, must be installed, not cancel in cooling-off and pay your first bill, and must claim within 40 days of your service starting, with the final bill showing the fee. If your Fibrus contract later ends early (other than through a breach by Fibrus that it accepts), Fibrus can reclaim the payment pro rata for the complete months left on the contract. Fibrus can withdraw the scheme at any time. For other routes, see how to leave broadband without an exit fee.
Cooling-off, contract start and equipment afterwards
- Your minimum term starts when the service goes live (the "Services Start Date" in Fibrus's terms), not when you order.
- Cooling-off runs until 14 days after the latest of the order confirmation, delivery of your equipment, or the service start date. If the service has already started when you cancel, you pay any installation, activation and call charges, charges for the period it was available, and the cost of any non-standard installation you asked for or damaged equipment. See the broadband cooling-off period for the general rules.
- What stays and what goes back: network equipment (cable, poles, ducts and the ONT) stays at your home when the contract ends; service equipment such as the eero routers must be returned unless Fibrus says otherwise.
- Charges to know about: Fibrus's price guide lists charges for replacing a damaged ONT or eero, moving the ONT within 15 metres of its original position, and not returning eero routers.
A checklist for your Fibrus installation
- When ordering: check whether you're on Fibrus's network or an Openreach area; get written landlord permission if you rent; check your routers and Wi-Fi guarantee; ask how your number will move.
- Before the day: two (or three) sockets close together; a router position; someone over 18 home for the slot and after; two working days' notice for changes; ask about a Battery Backup Unit if you rely on the landline.
- On the day: agree the route before drilling; see the speed test; sign off only when happy.
- Afterwards: don't cancel an old phone line until Fibrus confirms the number has moved; claim any buy-out within 40 days.

Fibrus installation FAQs
Is a Fibrus installation free?
Fibrus says standard installations are free, and its December 2025 price guide lists no connection or installation costs for them. A standard installation means overhead via telegraph poles, a new duct laid by Fibrus, or your existing duct if it needs no repair. Non-standard work, such as repairing a duct, an installation you choose instead of the free standard one, or a network extension, is charged and may need a paid survey first.
Does someone need to be home for a Fibrus installation?
Yes, for an engineer installation on Fibrus's own network. Someone over 18 who can agree the cable route and router position and sign off the work must be home for the whole appointment slot and for a few hours after, in case the engineer arrives near the end of the slot. Pets should be kept away.
Can Fibrus be activated without an engineer visit?
Yes, in Fibrus's Openreach Network areas where your home already has an Openreach ONT. Fibrus gives at least 14 days' notice of the remote activation, posts the eero router by Royal Mail, and Openreach checks the ONT is powered on. You plug in and set up the eero yourself, and Fibrus emails when the service is live.
Will Fibrus drill a hole in my wall?
On Fibrus's own network, yes: the engineer fits a cable on the outside of your home and drills a small hole to bring it to the ONT, which is fixed to an inside wall. You agree the entry point with the engineer, so think about where the router should go, because the ONT and router need to be close together.
Do I need to cancel my old provider when switching to Fibrus?
Not if you switch through One Touch Switch, which Fibrus says it uses. You contact only Fibrus, your current provider must send you the switching information, including any early termination charges, and the old service stops when the switch completes. Fibrus's terms also recommend not ending any existing service yourself until the Fibrus installation is complete and activated, so if you arrange anything separately, wait until Fibrus is live.
Will Fibrus Talk work in a power cut or with my alarm?
Not on its own. Fibrus's terms say neither its broadband nor Fibrus Talk works in a power failure, and alarms or healthcare devices that rely on a copper landline aren't supported. If you rely on your landline or have poor mobile signal, ask whether you qualify for a Battery Backup Unit, which keeps calls working for at least 60 minutes with a corded phone.
Can I get Fibrus if I rent my home?
Yes, with your landlord's agreement. Fibrus's residential terms say that by ordering you confirm you are either the owner-occupier or a tenant with legally binding permission from the owner to install Fibrus's equipment. Because the engineer drills a small hole through an outside wall and fixes the ONT inside, ask for that permission in writing before you order, and agree where the cable will come in.
