- Business broadband is typically sold without VAT shown in the headline price, then 20 percent VAT is added; VAT-registered firms can usually reclaim it, unlike consumers.
- Ofcom rules require providers to give business customers clear contract information and a short summary before signing, similar to consumer protections introduced under the Communications Act 2003 framework.
- A service level agreement (SLA) sets a contractual fix time; leased lines commonly carry a target repair window of several hours, while standard broadband relies on best-efforts repair.
- FTTP (full fibre) availability passed the majority of UK premises by 2025 according to Ofcom Connected Nations reporting, widening the gap with older FTTC copper-based lines.
- Ofcom's automatic compensation scheme is voluntary for providers and primarily covers residential and some small-business lines; many business and leased-line products sit outside it and rely on the SLA instead.
Business broadband costs more than home packages but adds SLAs, faster fault repair, static IPs, lower contention and VAT recovery. Choose FTTC, SOGEA, FTTP or a leased line based on how much downtime your firm can tolerate.

What business broadband actually is
Business broadband uses the same physical networks as home broadband: the Openreach copper and fibre infrastructure, and in some areas alternative networks built by independent providers. The wires in the street are often identical. What differs is the contract wrapped around the connection, the way faults are handled, and the commercial terms. A business package is not simply a home package with a higher price tag; it is a different product designed for premises where lost connectivity stops invoicing, card payments, cloud accounting and phone calls all at once.
The headline distinction is risk allocation. On a residential line, the provider repairs faults on a best-efforts basis and your remedy if things go wrong is limited. On a business line, the provider often commits in writing to a target fix time and a defined level of service. That commitment is the service level agreement, and it is the single most important reason businesses pay a premium.
Business versus home broadband: the real differences
Several features separate the two product tiers in the UK market. Not every business package includes all of them, so the contract summary matters.
Service level agreements and fault priority
Business connections usually carry an SLA setting out the target time to fix a fault and, on premium products, a guaranteed uptime percentage. Faults reported on business lines are frequently given higher priority in the repair queue, and some products include enhanced care levels from Openreach that shorten the response window and extend cover into weekends.
Static IP addresses
Home broadband typically assigns a dynamic IP that changes periodically. Business broadband commonly offers one or more static IP addresses, which stay fixed. A static IP matters if you host services on site, run a virtual private network for remote staff, operate certain card terminals, or need allow-list access to remote systems.
Contention ratio
Contention is the degree to which your connection shares capacity with other users at busy times. Business products often advertise lower contention, meaning fewer simultaneous users competing for the same backhaul capacity, which produces steadier speeds during the working day.
Support and contract protections
Business support lines often run longer hours and route to UK-based technical teams. On the regulatory side, Ofcom requires providers to give small-business customers clear pre-contract and contract information, and to summarise the key terms before you commit. Micro-businesses and small enterprises share some, though not all, of the protections afforded to residential consumers.
VAT treatment
Consumer broadband prices are quoted inclusive of VAT. Business broadband is generally quoted exclusive of VAT, with 20 percent added at the standard rate. The practical effect for a VAT-registered company is that the broadband cost is usually recoverable as input VAT, subject to the normal rules on business use, so the net cost can be lower than the gross figure suggests. A sole trader who is not VAT registered pays the VAT and cannot reclaim it.
Connection types explained
The connection technology determines speed, reliability and price more than the brand on the contract. UK business connectivity falls into a handful of categories.
FTTC (fibre to the cabinet)
FTTC runs fibre to the green street cabinet, then copper for the final stretch to the premises. Speed depends heavily on the copper distance, so a unit far from the cabinet sees slower throughput. FTTC is widely available and cheap, but it is being phased out as the copper network is retired.
SOGEA
SOGEA (Single Order Generic Ethernet Access) delivers the same broadband as FTTC but without a traditional phone line bundled underneath it. As the legacy analogue phone network is withdrawn, SOGEA has become the standard replacement for many copper-based broadband lines, paired with VoIP for telephony.
FTTP (full fibre)
FTTP runs fibre all the way to the premises, removing the copper bottleneck. It offers far higher and more symmetrical speeds and better reliability than copper-based options. Full fibre availability has expanded rapidly across the UK, and for most businesses able to get it, FTTP is the natural upgrade from FTTC or SOGEA.
Leased line (dedicated Ethernet)
A leased line is a dedicated, uncontended fibre connection reserved entirely for your business. Speeds are symmetrical (upload matches download), and the line carries the strongest SLAs in the market, often with guaranteed uptime and a short repair window backed by financial penalties. The trade-off is cost: leased lines run to several hundred pounds a month and involve an install lead time that can stretch to weeks or months where new fibre must be built.
| Connection type | Typical speed | Typical monthly cost range | Best for |
|---|---|---|---|
| FTTC | Up to around 80 Mbps down | £20 to £45 (ex VAT) | Small offices with light usage where full fibre is unavailable |
| SOGEA | Up to around 80 Mbps down | £22 to £45 (ex VAT) | Firms moving off the legacy phone line to VoIP |
| FTTP (full fibre) | 100 Mbps to 1 Gbps+ | £30 to £90 (ex VAT) | Most growing businesses needing reliable, fast connectivity |
| Leased line | 100 Mbps to 10 Gbps symmetrical | £200 to £900+ (ex VAT) | Firms where downtime is unacceptable or upload demand is heavy |
Cost ranges are indicative as of 2026 and vary by location, contract length, install requirements and bandwidth. Leased line pricing in particular depends on how far the premises sits from the nearest fibre and whether new civils work is required.
Understanding an SLA in practice
An SLA is a contractual promise about service quality. The components worth reading carefully are the target fix time, which states how quickly the provider aims to resolve a reported fault; the availability or uptime figure, often expressed as a percentage over a year; and the remedies, which set out what you receive if the provider misses its commitment. On leased lines these remedies are usually service credits calculated against your monthly charge.
The important nuance is that a higher uptime percentage sounds reassuring but translates into real downtime. A line promising 99.9 percent availability can still be down for several hours across a year and remain within the SLA. If your operation cannot tolerate that, you need either a stronger SLA, a backup connection on a separate technology such as mobile, or both. Treat the SLA as the headline difference between a business product and a home product, and read the repair window rather than the marketing.
Ofcom protections and the automatic compensation scheme
Ofcom regulates UK communications providers and sets rules covering contract transparency, switching and complaints handling. Business customers, particularly micro and small businesses, benefit from requirements that providers present clear information before sign-up and handle complaints through a defined process, with access to an alternative dispute resolution scheme if a complaint stalls.
The automatic compensation scheme is a separate, voluntary code that signed-up providers follow. It pays set amounts when a fault is not fixed within a defined period, when an engineer misses an appointment, or when a new service is not activated on the promised date, without the customer having to claim. Coverage centres on residential lines and certain small-business packages from participating providers. Many business and leased-line products sit outside the scheme because their SLA already provides stronger, contractually enforceable remedies. Check which framework applies to your specific package, because relying on the wrong one leaves you without the remedy you assumed you had.
How to choose
Start with downtime tolerance. If a few hours offline merely inconveniences you, a well-specified FTTP or SOGEA package is usually sufficient and far cheaper than a leased line. If downtime stops trading, costs you customers, or breaches your own commitments to clients, a leased line or a resilient dual-connection setup is the proportionate choice. Then weigh upload demand: video, large file transfers, cloud backups and hosted phone systems all lean on upload, where symmetrical FTTP and leased lines outperform asymmetric copper. Finally, factor the VAT position and contract length into the true cost rather than judging on the advertised monthly figure alone.
Frequently Asked Questions
What is the difference between business and home broadband?
Business broadband often uses the same physical line as home broadband but adds a service level agreement, faster fault repair, lower contention, static IP options and longer support hours. Prices are usually quoted excluding VAT, which VAT-registered firms can typically reclaim, whereas home prices include VAT that consumers cannot recover.
What is an SLA for broadband?
A service level agreement is a contractual promise about service quality, including a target fault-fix time, an uptime percentage and the remedies you receive if the provider misses them. On leased lines those remedies are usually service credits against your bill. Standard home broadband has no comparable guaranteed fix time.
What is a leased line?
A leased line is a dedicated fibre connection reserved entirely for one business, with symmetrical upload and download speeds and the strongest SLAs available. It is not shared with other users, so performance is consistent. The trade-off is a much higher monthly cost and a longer installation lead time than standard broadband.
Do I need a static IP?
A static IP address stays fixed rather than changing periodically. You need one if you host servers or services on site, run a VPN for remote staff, operate certain card payment terminals, or require allow-list access to external systems. Many businesses with only cloud-based tools do not need one, so check your actual requirements first.
What is the Ofcom automatic compensation scheme?
It is a voluntary code that participating providers follow, paying set amounts automatically when a fault is not fixed in time, an engineer misses an appointment, or a service is not activated on the promised date. It mainly covers residential and some small-business lines. Many business and leased-line products sit outside it and rely on their SLA instead.
