A Guide to Business Fibre Broadband and FTTP

Interconnectivity is more important to businesses than ever. Many businesses would find it difficult to function without a fast, reliable internet connection to the outside world, so making the right decision over which service you should choose and who should supply it is one of the most important business decisions that you can take.

The benefits of shopping around in a congested marketplace can be more than technical. When broadband works seamlessly it can become easy to forget about your contract, and price increases can then start eating into your bottom line. But which is right for you? It can get confusing and complicated, so SwitchPal is here to walk you through what can feel at times like a jungle of jargon and acronyms.

Traditional broadband, powered by copper cables through ADSL, is being phased out in favour of fibre broadband. But it’s not quite as simple as simply deciding to upgrade from ADSL to fibre, because there’s more than one type of fibre available, as well.

What is FTTP Broadband?

FTTP stands for “Fibre To The Premises”, and involves fibre optic cables being run directly into your premises. You’ll sometimes see or hear it being referred to as “full fibre broadband”. By comparison, FTTC stands for “Fibre To The Cabinet”, in which fibre optic cables are used to the nearest broadband enclosure (or ‘cabinet’ - these are the green metal boxes that you frequently see on streets) to you, but with the last bit of that data journey into your premises being made by copper wire.

What is the Difference Between FTTP and Standard Broadband?

Fibre optic cables carry data faster and more reliably than copper wires. Using copper for the wiring from the broadband cabinet (as with standard fibre broadband) or your local exchange (as with ADSL broadband) to your business will significantly slow down that connection.

How Does Fibre Optic Broadband Work?

Any document, sales transaction, photograph, or video that you send via broadband is essentially a string of data that your device converts into something useful to you. There are many moving parts involved in how quickly this movement and conversion of data occur from point A to point B, but the type of broadband connection used is probably the single most important link in this chain. Traditional ADSL broadband sends data by copper wire from an exchange to a cabinet near your premises, and then on by the same means. It relies on the existing landline telephone infrastructure. It’s cheap and relatively reliable, but it’s also slow, by modern standards.

Fibre broadband speeds up that journey to the cabinet by using fibre optic cables from the exchange, but although this connectivity solution is faster than solely using copper wires, the use of copper wires from cabinets to your premises still diminishes internet speed into your premises, so the physical distance from your premises to the cabinet box your company uses also has a direct impact on the maximum speed available to your company should you use this type of fibre connection.

Full-fibre broadband (FTTP) eliminates this “last mile” slowdown by installing fibre optic cables directly into your business. It’s also the case that even FTTC fibre requires you to ‘share’ your connection with others in your locality. This is why some find their speeds slowing during peak hours. With a connection going directly by fibre optic cable straight into your premises, this throttling of speed is also substantially reduced.

Business Fibre Broadband Benefits

There are three main advantages to using fibre broadband: bandwidth and speed, reliability and scalability.

Bandwidth and speed are essential, but they’re not the same thing. Bandwidth is best defined as the maximum data transfer rate of data (usually Internet connectivity), or a network's capacity, which is generally expressed in gigabits per second (Gbps) or megabits per second (Mbps).

One megabit per second (1 Mbps) is equivalent to 1,000 kilobits per second, and one gigabit per second (1 Gbps) is equivalent to 1,000 megabits per second. Bandwidth is not the same as speed, as bandwidth refers to the maximum amount of data that can be transferred per second. Internet speed is based on the actual rate of data transfer per second.

Copper-wired ADSL broadband maxes out at around 10/15 Mbps, while FTTC fibre reaches speeds of around 70/80 Mbps. In contrast, FTTP broadband can achieve speeds of 1 Gbps, which is nearly 100 times the speed of ADSL broadband and more than ten times the speed of FTTC fibre broadband.

Fibre broadband is also more reliable than traditional copper-based wiring. All data signals degrade over a range, but fibre offers significantly better signal durability. Fibre only loses 3% of the signal over distances greater than 100 metres, compared to copper's 94% loss of signal. It’s also more resistant to interference on the line - copper conducts electricity while fibre optic cables do not, and fibre is also smaller and lighter than copper cabling.

Fibre broadband also offers a degree of future-proofing. Copper ADSL lines are on their way out, but FTTC fibre speeds can also be limiting. FTTP networks are designed to handle gigabit speeds. With technological advancements, network operators can leverage the existing infrastructure to deliver even higher speeds without significant upgrades. This makes scalability as straightforward as possible.

Business FTTP vs. a Leased Line

Even with an FTTP connection, you will have to deal with contention. The contention occurs when users share your bandwidth, resulting in slower connection speeds during peak usage periods. Where FTTP is available, a leased line provides a dedicated fibre optic service that connects directly to a customer’s premises, bypassing the need to share infrastructure and boosting connection speeds.

Disadvantages of Fibre Optic Broadband

Availability can be an issue, though it is improving quickly. As of early 2026, full fibre (FTTP) was available to around 82% of UK homes, up from roughly half a few years ago, so whether you can get it still depends on where your business is located. Even FTTC broadband is on its way out. Openreach, the UK’s largest network builder, is investing around £15 billion to bring full fibre to 25 million premises by December 2026, with plans to reach up to 30 million by 2030.

As fibre optic cable is lighter and thinner than copper wiring, it is also prone to physical damage. Fibre optic cables are easily damaged when building renovations are underway, and even a single cut can be disruptive. You can mitigate this by understanding exactly where your cable enters and passes through your premises. This is especially important if your work premises are due to undergo renovation; it is not uncommon for fibre optic cables to get damaged during building work.

Cost is another significant factor. The costs of fibre optic cabling are lower over the long term, but they can still be expensive to install. You need to have specialist equipment to check all is working as it should, and you also need to have the right worker on hand to set up the fibre optics equipment for you. These costs can quickly add up, so it's helpful to know exactly what you need to include in your budget.

The Importance of Secure FTTP Broadband for Businesses

Regardless of your business, the security of the data you send and receive is critical. Data breaches can be financially and reputationally ruinous. Copper cables can be more vulnerable to hackers who use cable-tapping methods to steal data and information. Fibre cables aren’t as easy to tap and so offer a more secure connection. Fibre cables are also less likely than copper cables to be affected by electromagnetic interference, which can be caused by heavy machinery being used in close range and disturb the speed and reliability of your connection.

How Does Fibre Broadband Impact Cloud-based Services?

Cloud-based services have transformed the way we conduct business, playing a vital role in fostering collaboration and enabling teams to access and edit shared files in real-time. A reliable and fast broadband connection is critical to get the best use of these services, to maintain services and ensure that you're getting the maximum productivity from your staff. Nothing affects productivity more than downtime that has come about because the internet has gone down!

Choosing the Right Fibre Broadband Plan

The three main considerations when choosing a fibre broadband plan are bandwidth and speed, scalability and budget. Faster and even more reliable connections are more desirable, but they can come at a cost. A leased FTTP line carrying a fibre optic connection into your building at 1Gbps is considerably more expensive than a simple 10Mbps ADSL connection, which may be sufficient for a small trader; the set-up costs can also be high.

You should also consider your future business plans. Since fibre optic cable can be damaged during building work, you may wish to stay with copper until planned renovation work has been completed. Also, please note that installation can take some time. Business broadband lines can often be installed and operational within 10-15 days; however, leased FTTP lines have a significantly longer lead time for installation and can take up to 60 days for end-to-end deployment.

Are There Any Government Incentives for Businesses to Switch to Fibre Broadband?

Businesses in rural locations which meet the following criteria can use vouchers to support the cost of installing new gigabit-capable connections when part of a group project.

• Existing broadband speeds are typically less than 100 Mbps.

• A gigabit-capable network isn’t likely to be built to that area commercially in the near future.

• There is no government-funded contract planned or in place to improve the network already.

To qualify for a business voucher, you will be asked to self-certify that you are a Small or Medium-sized Enterprise (SME), as defined by sections 465 to 467 of the Companies Act 2006, which can be summarised as:

• Up to 249 employees and an annual turnover no greater than £36 million; and/or

• An annual balance sheet total not exceeding £18 million.

You will be asked to prove you are an SME or sole trader. You will also need to self-certify that your organisation has not received too much public subsidy - specifically, less than 325,000 Special Drawing Rights (SDRs) in public grants over the current and previous two financial years, including the value of the voucher itself.

In plain terms, Special Drawing Rights (SDRs) are an international currency unit set by the International Monetary Fund; 325,000 SDRs works out at roughly £330,000, though the exact figure moves with the exchange rate. This cap replaced the previous €200,000 ‘de minimis’ subsidy limit after the UK left the EU on 31 December 2020. You can check the current SDR-to-GBP rate on the IMF’s website.

Not-for-profit and charitable undertakings which qualify as SMEs are eligible in the same way as for-profit enterprises. You can check your company’s eligibility for these vouchers on the government’s Gigabit Broadband Voucher Scheme website.
