UK business broadband: what you are actually buying

Business broadband usually runs on the same fibre as the house next door. The premium of roughly £15 to £50 a month buys a faster fault-fix promise, a static IP, symmetric upload, UK support and a VAT invoice. Whether that is worth it comes down to one question: what does an hour offline cost you?

Do you actually need it?

Plenty of UK businesses pay the premium and get nothing back. Plenty of others limp along on a consumer package that costs them a day's trading every time a cabinet floods. Find yourself below before you look at a single price.

Consumer is probably fine
One person, light cloud use
  • An outage is annoying rather than expensive
  • You can work from a cafe or a 4G hotspot for half a day
  • No static IP, no inbound connections, no heavy upload
  • You claim broadband as a home-office expense either way
Business broadband
Most UK SMEs land here
  • An outage costs billable hours or a missed deadline
  • Several people share the connection
  • You need a static IP for VPN or hosted services
  • Customers expect connectivity: a shop, cafe, clinic or let
  • You want a VAT invoice and clean accounting
Leased line
Downtime is genuinely critical
  • E-commerce, call centre, financial services, clinical records
  • Twenty-plus staff, or sustained gigabit symmetric use
  • Budget for £200 to £2,000 a month
  • A 30 to 90 working day install does not block you

Most small businesses sit in the middle column, and a minority grow into the third as connectivity becomes load-bearing.

What the premium buys

The five differences that actually matter

Business broadband is not a different physical network. Most of it runs over the same Openreach fibre, Virgin Media cable or altnet build as the consumer product. What differs is the commercial wrapper.

Fault fix promise
Next working day target. Ofcom automatic compensation pays £10.34 a day after two full working days.
Same-day or four-hour fix during business hours, backed by contractual service credits.
Static IP
Dynamic address, and carrier-grade NAT on some altnets and all mobile broadband.
One static IPv4 included or £4 to £8 a month, usually with an IPv6 block on top.
Upload speed
Asymmetric. A 500 Mbit/s package typically uploads at 75 Mbit/s.
Symmetric on most business FTTP tiers: 500/500, 1000/1000, sometimes 10G.
Support
General queue, often offshore, limited authority to escalate.
Dedicated UK business line with priority routing and escalation rights.
Contract and billing
12 to 24 months, VAT-inclusive pricing, no reclaimable invoice.
12 to 36 months, VAT invoice, tax-deductible, and genuinely negotiable.

The premium is typically £15 to £50 a month over the equivalent consumer package. Whether it pays for itself depends almost entirely on the first row.

That last row is worth dwelling on. Consumer prices are fixed; business prices are quoted, and quotes move. Two or three competing quotes before you sign, and again at every renewal, typically save £10 to £30 a month against the first number.

The main event

Service-level agreements, read properly

The SLA is the contractual promise to fix a fault within a set window. It is the single thing most business buyers are paying for, and the wording matters more than the headline. Here is the same fault, reported at 09:30 on a Tuesday, under four tiers.

  • 4 hoursPremium business
    Back by lunchtime. You lose a morning.Standard on leased lines. Available on premium FTTP tiers from BT, Virgin Media, Vodafone, Andrews & Arnold and M247.
  • 8 hoursStandard business
    Back by close of play. You lose a day, not two.The common middle tier on business FTTP, and where the premium starts paying for itself.
  • 12 hoursEntry business
    Possibly back overnight. Possibly tomorrow.Better than consumer, but a fault after lunch runs into the next day anyway.
  • Next dayConsumer and entry tiers
    Back some time Wednesday. A day and a half gone.A Friday afternoon fault becomes a Monday fix. This is the gap the premium is buying out.

Fix targets apply during business hours unless the contract says 24x7.

Five questions to ask before you believe an SLA

  • When does the clock start? Some run from your report; others only once the provider has verified the fault, which quietly adds hours.
  • Does it include the Openreach wait? On Openreach fibre, your provider can only promise what Openreach promises them.
  • What counts as fixed? Some contracts treat a degraded backup state as a fix. Others require full service.
  • Is the install period excluded? Many SLAs do not apply during commissioning, exactly when new lines wobble.
  • Is there money behind it? A target with no service credits is marketing. Check the cap too: many stop at one month's fee, so a long outage cannot pay you back in full.

Ofcom automatic compensation and business contracts. The scheme paying £10.34 a day after two full working days of total loss, £32.31 for a missed engineer appointment and £6.46 a day for a late start applies mainly to consumer contracts. Rates are those effective from 1 April 2026, uprated each April.

Business contracts typically opt out in favour of their own SLAs. Micro-businesses of ten or fewer employees sometimes still qualify. Check yours, and see our guide to the current rates.

Translating the marketing

What an uptime percentage really means

Uptime guarantees are quoted as percentages because percentages sound reassuring. Converted into hours of trading, they are much easier to judge against what an outage costs you. One scale below: bar length is permitted downtime.

99.0% 3.65 daysa year offline
99.5% 1.82 daysa year offline
99.9% 8.8 hoursa year offline
99.95% 4.4 hoursa year offline
99.99% 53 minutesa year offline

Business FTTP typically promises 99.5% to 99.9%; leased lines promise 99.9% to 99.99%.

The jump worth paying attention to is 99.5% to 99.9%: nearly two trading days a year against a single working day, and usually the line between a standard and a premium tier. The jump to 99.99% costs far more and only earns its keep if an hour offline costs more than the annual price difference.

The technology

Six connection types, compared

  • FTTP business
    Speed100 Mbit/s to 10 Gbit/s, symmetric options · 5 to 15 ms
    Cost and install£40 to £200 a month · 2 to 4 weeks
    VerdictThe right answer for most UK businesses in 2026.
  • FTTC business
    Speed20 to 80 Mbit/s down, 20 Mbit/s upload ceiling · 10 to 25 ms
    Cost and install£30 to £60 a month · 1 to 2 weeks
    VerdictTransitional only. Copper services close on 31 January 2027.
  • Leased line
    Speed10 Mbit/s to 10 Gbit/s, always symmetric · 1 to 5 ms
    Cost and install£200 to £2,000+ a month · 30 to 90 working days
    VerdictDedicated, uncontended, strongest SLA. Detail below.
  • EFM
    Speed10 to 35 Mbit/s symmetric · 10 to 20 ms
    Cost and install£150 to £400 a month · 3 to 6 weeks
    VerdictLargely displaced by FTTP. Avoid unless nothing else reaches you.
  • 4G or 5G fixed wireless
    Speed30 to 500 Mbit/s · 20 to 60 ms
    Cost and install£30 to £80 a month · same day
    VerdictExcellent as backup or a stopgap. Watch for CGNAT.
  • Fixed wireless access
    Speed50 Mbit/s to 1 Gbit/s · 5 to 15 ms
    Cost and install£100 to £500 a month · 2 to 8 weeks
    VerdictNiche but genuinely useful in rural Scotland, Wales and remote England.

Two practical notes. Treat FTTC as a stopgap: the PSTN switch-off on 31 January 2027 closes the legacy services beneath it, and our switch-off continuity hub has the device-by-device checklist. And if 4G or 5G would be your primary line rather than a backup, ask for a public IP first, because carrier-grade NAT breaks inbound connections, VPN endpoints and remote camera access however fast the line tests. Our rural guide covers the no-fibre fallbacks, and our full-fibre explainer covers the market.

Two things consumer packages rarely give you

Static IPs and upload speed

What a static IP unlocks
  • Hosting on site: mail, files, cameras, point-of-sale with remote access all need a stable address.
  • VPN endpoints: staff connecting back to the office need to know where the office is.
  • IP whitelisting: some banking platforms, B2B portals and filing systems only accept declared addresses.
  • Email deliverability: a stable address builds sender reputation; a rotating one cannot.
  • Blocks: a /29 gives six usable addresses for £15 to £30 a month. IPv4 is scarce; put new services on the free IPv6 block. Full setup in our static IP guide.
Why upload catches businesses out
  • Cloud backup: 100 GB nightly takes about 3 hours on a 500/75 line and about 30 minutes on 500/500.
  • Video calls: five staff on one call all push video up the same connection. 75 Mbit/s strains; 500 does not notice.
  • Big files: CAD, video, builds, image-heavy uploads, audit bundles.
  • Cameras: a 4K camera streams 4 to 8 Mbit/s. Eight of them fill a 75 Mbit/s upload on their own.
  • Availability: symmetric business FTTP is widespread in 2026 at a £10 to £30 premium. Work out your own number with upload versus download.
When it fails anyway

The resilience ladder, rung by rung

An SLA tells you how fast someone will come and fix it. Resilience means you do not care, because you are still trading. Each rung costs more and protects against more.

  1. One connection, no backupFine for a sole trader who can tether to a phone. Every fault is an outage.No extra cost
  2. A 4G or 5G backup SIM in the routerCovers cabinet faults, cable damage and provider incidents. The best value step on this ladder.Around £20 to £30 a month
  3. A multi-WAN router with automatic failoverTwo connections, switchover in under ten seconds. Peplink, DrayTek and Cisco Meraki are the common UK choices.£400 to £500 once, plus the second line
  4. Bonded broadbandTwo connections combined into one, bandwidth adding up, failover built in. Managed from BT Business, Andrews & Arnold and Daisy.Both lines plus a managed fee
  5. Diverse-route connectionsTwo lines that physically leave the building by different paths, ideally on different networks. This survives a regional incident.Around £160 a month for two business FTTP lines
  6. Leased line, with or without a backupDedicated circuit, four-hour fix, 99.9% to 99.99%. The top of the ladder, priced like it.£200 to £2,000+ a month

For most single-site small businesses, rung two or three is the right stopping point: under £50 a month covers the overwhelming majority of real outages. Our 4G backup guide lists providers who build failover in, and avoiding downtime when you work from home covers the home-office version. Larger and multi-site businesses increasingly buy this as SD-WAN, managed by BT, Vodafone, Daisy or M247. And if the worst happens to the provider itself, here is what happens if your provider goes out of business.

Whatever the shortlist, get two or three quotes, because business pricing moves and consumer pricing does not.

In practice

Six business situations and what each needs

  • Sole trader at home

    Cloud tools, a few video calls, light uploads. An outage is irritating, not expensive.

    Buy: business FTTP at £40 to £60 with a static IP, or consumer plus a 4G hotspot on a tight budget. Home office walkthrough, or the sole trader guide. Broadband for home working covers the consumer side.

  • Small office, 5 to 15 staff

    Shared connection, daily calls, cloud accounting, CRM, occasional VPN.

    Buy: 500 to 1000 Mbit/s symmetric at £80 to £150, 4G failover at £20 to £30, a /29 or /30 block at £15 to £20. See the SME guide and serviced offices.

  • Retail and hospitality

    Card payments, guest Wi-Fi, staff devices, often cameras. Downtime stops revenue on the spot.

    Buy: 200 to 500 Mbit/s with 4G or 5G backup as standard and a separate guest network. Resilience beats raw speed. See card machines and EPOS, guest Wi-Fi, retail shops, cafes and takeaways and B&Bs and holiday lets.

  • Professional services

    Accountancy, law, architecture, consultancy. Secure documents, client calls, big uploads, VPN into client systems.

    Buy: 500 to 1000 Mbit/s symmetric with a four-hour SLA where available, static IPs, failover. Zen or Andrews & Arnold suit technical practices. See professional services, salons and clinics and trades and mobile teams.

  • E-commerce and software

    Sustained large uploads, build servers, developer remote access, sometimes self-hosted services.

    Buy: gigabit symmetric FTTP or a leased line if scale justifies it, multiple static IPs, diverse-route bonding. See creators, agencies and large uploads and pop-ups and short leases for the temporary version.

  • Multi-site business

    Several offices, a chain, or clinics. Site-to-site VPN and one consistent SLA across the estate.

    Buy: account-managed broadband with SD-WAN over the top: leased line at head office, business FTTP at satellites, always bespoke-quoted. See the multi-site guide.

The top tier

Leased lines: when they are worth it

A leased line is a different product, not a faster tier. Business FTTP shares the network with other customers; a leased line is a dedicated fibre circuit from your premises to the provider's core with no contention at all.

  • Bandwidth: 100 Mbit/s to 10 Gbit/s, always symmetric, always dedicated. No peak-time slowdown, because nobody else is on it.
  • SLA: typically 99.9% to 99.99% uptime with a four-hour fix and service credits that mean something.
  • Latency: 1 to 5 ms with very low jitter, which suits VoIP at scale and big remote-desktop estates.
  • Install: 30 to 90 working days, because the fibre usually has to be physically pulled to your building.
  • Cost: a 100 Mbit/s line in a UK city runs £350 to £500 a month; 1 Gbit/s runs £600 to £900; rural premises cost more because of the civils.

The honest test is arithmetic: a leased line earns its place when the downtime it prevents costs more than the price difference against business FTTP, when you genuinely use gigabit symmetric continuously, or when a regulator or client contract effectively requires it. That tends to arrive around twenty staff, or earlier for e-commerce, call centres, financial services and clinical records. While you wait out the install, mobile broadband as a temporary bridge covers the gap.

Main providers: BT Business (BTnet, the largest), Virgin Media Business, Vorboss in London, M247, Daisy, plus CityFibre and Openreach Ethernet resold through various retailers. A gigabit line at £700 a month in central London might be £400 in a regional city and £1,500 somewhere remote.

The small print

Contracts, switching and One Touch Switch

One Touch Switch does not cover you

This surprises people. The consumer process where your new provider handles everything covers consumer broadband only. Business switching still runs the legacy route: a Letter of Authority, an agreed cessation date, a planned activation date. In practice that means five to fifteen working days, usually a short overlap paying both providers, and occasionally a gap. If your business cannot tolerate a gap, our switching without downtime guide covers the sequencing.

Contract length and exit

Business terms run 12 to 36 months. Longer unlocks lower headline pricing and locks you in; 12 months costs a little more and keeps you flexible; rolling monthly exists at a premium and suits pop-ups and premises pending sale. Early exit normally costs the remaining months, so check the calculation before signing. Full detail in our business contract guide.

The ten-employee cliff edge

Businesses with ten or fewer employees get some consumer-style protections under Ofcom's General Conditions: clear pre-contract information, penalty-free exit if the provider materially changes the deal, and access to an ADR scheme. Above ten, you are on contract terms alone. Know which side you sit on.

Annual price rises

The pounds-and-pence rule for in-contract rises applies mainly to consumer deals. Business contracts often keep CPI plus a fixed percentage, typically 3.9%, which compounds over a 36-month term. Budget on the escalated figure, not month one.

Use switching as leverage

Providers usually match a competing quote rather than lose you. Get two or three before renewal and put them in front of your account manager; renewal offers are frequently far better than the auto-renewal price.

The bit that changes the maths

VAT and tax treatment

Business broadband looks dearer than consumer until you account for VAT and deductibility. For a VAT-registered business it is often cheaper in net terms at a higher headline price.

VAT reclaim

Business providers issue VAT invoices showing net, VAT and gross separately. On a bill of £100 plus VAT, you pay £120, reclaim the £20, and the real cost is £100. A consumer package advertised at £100 including VAT has no reclaimable invoice, so the real cost stays £100 with only £83.33 of service inside it. That gap is why headline comparisons mislead.

Deductibility

Broadband used wholly or mainly for business is fully deductible: against income tax for sole traders and partnerships, corporation tax for limited companies. Self-employed home workers choose between HMRC's flat rate (£10, £18 or £26 a month by hours worked from home) and apportioning the actual bill; business broadband suits the second because the VAT invoice makes the evidence easy.

Equipment and business rates

Routers, switches, multi-WAN devices and UPS units qualify for capital allowances, and the Annual Investment Allowance means most small businesses deduct them in full in the year of purchase. Business broadband at a home address does not by itself trigger business rates: a mixed-use home office normally stays within council tax.

General information, not advice. Tax positions vary and rates change; figures are current at August 2026. For anything affecting a real filing, speak to an accountant. HMRC's guidance is at gov.uk/expenses-if-youre-self-employed.

Free and independent

Where to get free help

  • Self-employed and small business

    HMRC self-employed guidance covers allowable expenses. The Federation of Small Businesses offers legal advice and dispute support to members. The British Chambers of Commerce runs regional support.

  • Faults and contract disputes

    Raise it with the provider first. Unresolved after eight weeks, escalate to the Communications Ombudsman or CISAS, depending on your provider's scheme. Our compensation and service failure guide maps the route.

  • Regulatory questions

    Ofcom sets the baseline through the General Conditions but does not arbitrate individual disputes. Complaints still count towards its view of provider performance, so they are worth filing. Thinkbroadband is strong on technical analysis and availability.

  • Technical setup

    Local managed service providers typically charge £40 to £100 an hour for multi-WAN configuration, VLAN segregation and VPN setup. For a business without in-house IT, that is usually cheaper than the hours lost working it out.

Common questions

Frequently asked questions

What is the main difference between business and consumer broadband?

The fault-fix promise. Business packages target same-day or four-hour repair with contractual service credits; consumer targets next working day. Everything else, static IP, symmetric upload, UK support and VAT invoicing, is real but secondary. The underlying network is usually identical.

Do I need business broadband if I work from home as a sole trader?

Often not. If an outage costs you an awkward afternoon rather than money, consumer broadband plus a 4G hotspot is cheaper and adequate. Switch when an outage starts costing billable hours, when you need a static IP, or when VAT reclaim tips the maths.

Can I switch business broadband using One Touch Switch?

No. One Touch Switch covers consumer broadband only. Business switches use a Letter of Authority and take five to fifteen working days, usually with a brief overlap where you pay both providers.

Should I get a leased line or business FTTP for a small office?

Business FTTP, almost always. It gives 500 to 1000 Mbit/s symmetric at £80 to £150 a month with a same-day or four-hour target. A leased line at £350 to £900 only earns its keep when downtime costs more than the difference, or when a regulator or client contract effectively requires one.

Is business broadband tax-deductible?

Yes, when used wholly or mainly for business, against income tax or corporation tax depending on your structure. VAT-registered businesses also reclaim the VAT on the invoice, which consumer packages do not allow. Speak to an accountant for your own position.

Can I get a static IP with business broadband?

Almost universally. Most providers include one IPv4 address or charge £4 to £8 a month, usually with an IPv6 block alongside. Andrews & Arnold, Vorboss and Zen's premium tiers include them as standard. Blocks of four, eight or sixteen addresses cost more.

What do UK business broadband packages cost in 2026?

Roughly: £35 to £60 for sole trader and home office FTTP with a static IP; £60 to £150 for a small office on 500 to 1000 Mbit/s symmetric; £100 to £250 for mid-market with failover and a four-hour SLA; £200 upwards for leased lines. Treat every figure as an upper bound, because business pricing is negotiable.

Does the Ofcom automatic compensation scheme cover my business?

Usually not. It is built for consumer contracts, and business packages generally opt out in favour of their own SLA. Micro-businesses of ten or fewer employees sometimes still qualify. The current rates are £10.34 a day for total loss, £32.31 for a missed appointment and £6.46 a day for a late start, effective 1 April 2026.
