O2 Business (Daisy): Business Broadband Review

If you want to see which networks reach your premises before you ask for a quote, our guide to business broadband providers in your area explains how coverage works.

What Broadband Packages Does O2 Business Offer?

O2 Business sells four types of connection. In practice, the one you're offered depends on what's available at your address rather than a fixed menu.

O2 Business business broadband page checked 2 November 2026.

For dedicated, uncontended speeds up to 10 Gbps, O2 Business also sells leased lines.

What Happened to Daisy's Online Prices?

Until recently, Daisy published fixed prices on its Daisy Shop for micro and small businesses. When we checked on 2 November 2026, the shop redirected to an O2 Business mobile shop, and the broadband pages no longer loaded. These were the last prices Daisy listed for 24-month contracts, as captured in search results in 2026.

Treat these as a guide to how O2 Business priced small business broadband, not as a quote. Prices may have changed, and the packages are no longer available to order online.

How Much Does O2 Business Broadband Cost?

Why Is There No Published Price?

O2 Business now prices broadband by quote. An independent comparison published in October 2026 also found Daisy had been quote-only since the April 2026 rebrand. For you, that means two things: you can negotiate, and you need to read the order form carefully, because it decides your price, your annual rise and any service level.

It's worth noting that O2 Business's mobile airtime still has a published rise: £1.50 a month every April, according to its shop small print. If you bundle mobiles with broadband, you'll have two different rise rules on one account.

How Do O2 Business Price Rises Work?

O2 Business's June 2026 terms set three different rules for fixed services such as broadband, depending on when you signed and how big your business is.

Daisy Communications Ltd trading as O2 Business, terms and conditions, conditions 11.2.9 to 11.2.11, June 2026.

The split exists because of an Ofcom rule. Since 17 January 2025, providers must set out mid-contract rises in pounds and pence for consumers and for small businesses with 10 or fewer workers. Larger businesses aren't covered, which is why O2 Business can still use CPI plus 3.9% for them.

Daisy's terms include their own worked example: a £21 monthly charge rises to £22.45 in the first April if CPI is 3%, then to £23.93 the following year if CPI is 2.7%. That's a rise of about 14% over two years.

Separately, Daisy's price information page says that from 1 April 2026 most products rose by CPI plus 3.9%, while leased lines rose by 10%, maintenance by 20% and hosting by 25%. If you're an existing customer, check which rule applies to your contract.

What Will You Pay Over the Contract?

Using the last listed Full Fibre 150 price as an example, a 24-month contract starting in November 2026 would look like this for a business with 10 or fewer workers:

The result is an average of about £30.86 a month, roughly £46 more over the term than the headline price suggests. That's a smaller uplift than Virgin Media Business's £3.50 April rise, which adds about £84 over a similar contract, as we explain in our Virgin Media business broadband review.

Contract Length, Notice and Exit Fees

When we read through O2 Business's terms, these were the clauses most likely to affect your costs:

• Rollover (more than 10 workers): when your minimum term ends, the contract renews automatically for 12 months. To leave, you must give written notice at least 90 days before the end of the minimum term or rollover period (conditions 5.1.1 and 5.1.3).

• Notice (10 or fewer workers): you can end fixed services with 30 days' written notice, taking effect no earlier than the end of your minimum term (condition 5.1.4).

• Leaving early: you pay at least the outstanding line rental and subscriptions for the rest of the minimum term or notice period, plus costs and an administration charge of at least £300 (condition 16.2.2).

• Changes to your detriment: if O2 Business changes charges or terms in a way that's materially worse for you, you have 30 days from publication to object in writing and can end the affected service (conditions 11.2.2 and 16.2.7).

• Disputing a bill: you must raise it in writing within 14 days of the invoice date (condition 12.19).

• Line rental and calls: if you rent a line from O2 Business, the terms commit you to using it for calls too, or you may be charged the difference (condition 5.4.3).

• Moving premises: O2 Business will try to move your service and keep your number. If it can't, a new line and a new contract are needed, and engineer and admin charges apply (conditions 13.10 and 13.11).

When we speak to business owners about switching, the rollover clause is the one that most often catches larger firms out. If your business has more than 10 workers, put the 90-day deadline in your diary on the day you sign.

How Fast Is O2 Business Broadband?

Speed depends almost entirely on the network O2 Business can reach at your address. Its business broadband page lists full fibre up to 2,000 Mbps and part fibre up to 330 Mbps, with symmetrical speeds up to 2 Gbps "depending on network availability". Daisy's own broadband page lists full fibre at up to 1 Gbps, so ask which figure applies to you.

Is There a Minimum Speed Guarantee?

Daisy signed up to Ofcom's Voluntary Code of Practice on business broadband speeds in August 2019. Under the code, you should receive a realistic speed estimate and an estimated minimum guaranteed download speed before you buy. Ask for both figures in writing with your quote.

It's worth noting that the general terms say O2 Business has no liability if your line doesn't reach the maximum advertised speed (condition 5.2.6). The speed code gives you more protection than the general terms do, so make sure the minimum speed is on your paperwork.

What If You Need a Dedicated Connection?

All four broadband types are shared connections, so speeds can vary at busy times. If your business can't tolerate that, O2 Business also sells leased lines with symmetrical speeds up to 10 Gbps.

Our business broadband vs leased lines guide explains when the extra cost is worth it.

What Features Does O2 Business Broadband Include?

Router and Static IP

Daisy's broadband FAQs say you'll get a free router and a static IP address with all broadband products. A static internet protocol (IP) address is a fixed address for your connection, useful for remote access, virtual private networks (VPNs) or hosting. That's more generous than Virgin Media Business, which includes one only from Voom 600 upwards. Note that the last Daisy Shop listings charged £9.99 postage and packing for the router.

Our static IP business broadband guide covers when you need one.

4G Back-Up

O2 Business offers 4G mobile broadband at up to 150 Mbps, with 10GB or unlimited data. You can use it as a temporary connection before your fixed line arrives or as a back-up if your main connection fails. Its broadband page describes this as a temporary or automatic back-up, so ask whether the failover on your quote switches over automatically or needs you to plug it in.

DDoS Protection

Daisy's full fibre page lists free DDoS security. The terms describe DDoS protection as an on-demand service for use during an attack, and allow O2 Business to divert all your traffic if an attack threatens its network (condition 5.7.6). For most small businesses, this is a useful extra rather than a reason to choose a provider.

Phone Lines and Bundles

O2 Business sells cloud-based phone systems, SIP trunking and mobiles alongside broadband. Bundling can simplify billing, but it also means more than one rise rule on one account.

Our guide on how to compare SME phone and broadband bundles explains what to check.

Is It Ready for the PSTN Switch-Off?

Yes. All O2 Business broadband products are digital, and Daisy says it has sold only fibre-based broadband and digital phone lines since 2023. That matters because Openreach is due to switch off the old copper phone network in January 2027.

How Reliable Is O2 Business Broadband?

What Does O2 Business Promise?

The headline claims vary by page. O2 Business's connectivity page says "99% reliability", while its small business page says "99.9% uptime". Neither page says how the figure is measured or over what period.

The contract is more cautious. Daisy's general terms say O2 Business will use "reasonable endeavours" to fix faults as soon as practicable, and that it has no liability for any fault or interruption to fixed services (condition 5.2.2). They also exclude loss of revenue and profit (condition 14.2) and cap overall liability at 110% of what you paid in the previous 12 months, or £10,000 in the first contract year (condition 14.1).

In practice, any specific fault-fix target or service credit would be set out on your order form or in service-specific terms. We couldn't find a published broadband service level agreement (SLA) for O2 Business. Ask for the target fix time, the hours it applies to, and any compensation in writing before you sign.

How Does That Compare?

What Does Ofcom's Data Say?

Ofcom's quarterly complaints tables cover the largest residential providers, and neither O2 Business nor Daisy appears in them. That means there's no independent regulator data on how O2 Business handles broadband complaints.

Our guide to company broadband reliability explains what to look for instead.

What Do Business Customers Say About O2 Business?

Daisy Group holds a Trustpilot rating of 4.7 out of 5 from 24,327 reviews, as of November 2026, in Trustpilot's "Excellent" band. Of those, 87% are 5-star, 6% are 1-star, and 10,018 were posted in the last 12 months. By comparison, BT Business holds 3.7 out of 5 and Virgin Media Business 1.1 out of 5.

Three caveats matter. First, Trustpilot labels Daisy as a company that invites customers to review, and most recent reviews are marked "Invited", typically after a support call. That tends to lift scores. Second, the profile covers every Daisy product, from phone systems to mobiles, so it isn't a pure broadband score. Third, the separate O2 Business shop profile on Trustpilot scores 1.3 out of 5 from 92 reviews, so the score you see depends on which brand you look up.

The themes in recent reviews are consistent:

• Praise for named support agents who resolve technical and billing issues quickly

• Billing errors, including overcharging and slow refunds, in several 1-star reviews from October 2026

• Difficulty cancelling lines, with one reviewer still being charged 18 months after asking to cancel

• One broadband customer whose line was switched to another provider without consent twice, with a long wait for Openreach to restore it

O2 Business Broadband: Pros and Cons

Which O2 Business Option Is Right for Your Business?

If downtime would cost you money, a leased line or a provider with a published fix time and service credits may be a better fit.

Common Misconceptions About O2 Business and Daisy

"O2 Business only does mobiles." It sells broadband, leased lines, phone systems and IT too. The name causes confusion because "O2 Business" was long used for O2's business mobile plans, and the new O2 Business shop only sells mobiles.

"Daisy has closed." It hasn't. Daisy Communications Ltd is the company behind O2 Business, and existing contracts continue under the same terms.

"O2 Business broadband runs on the O2 mobile network." Only the 4G product does. Fixed broadband runs over Openreach, Virgin Media or other fibre networks, depending on your address.

"Price rises are always fixed now." Only for businesses with 10 or fewer workers who signed on or after 17 January 2025. Larger businesses face CPI plus 3.9%, and older contracts follow RPI.

Who Should Consider O2 Business?

O2 Business broadband is worth considering if your business:

• Wants one supplier for broadband, phones, mobiles and IT support

• Values a support team you can call and is comfortable negotiating a quote

• Needs a static IP without paying extra

• Has 10 or fewer workers and wants a known pounds-and-pence price rise

• Is at an address where other providers offer limited options

Who Should Look Elsewhere?

Look at other providers if your business:

• Wants to compare published prices and order online

• Has more than 10 workers and wants to avoid inflation-linked rises or automatic rollover

• Needs a contractual fault-fix time with compensation

• Has had billing problems before and wants a simpler account

FAQs About O2 Business Broadband

Is O2 Business the same as Daisy?

Yes. O2 Business is the trading name of Daisy Communications Ltd. It was called O2 Daisy from August 2025 and rebranded as O2 Business on 29 April 2026, following the merger of Virgin Media O2's business division with Daisy Group.

How much does O2 Business broadband cost?

There's no published price as of November 2026, so you'll need a quote. Daisy's last listed small business packages started at £27.95 a month ex VAT for Full Fibre 100 on a 24-month contract.

Does O2 Business increase prices during the contract?

Yes, every April. Businesses with 10 or fewer workers that signed on or after 17 January 2025 get a fixed pounds-and-pence rise set on their order form. Larger businesses face CPI plus 3.9%, and contracts signed before 17 January 2025 rise by RPI.

Does O2 Business broadband include a static IP?

Yes, according to Daisy's broadband FAQs, which say all broadband products come with a free router and a static IP address. Confirm it on your quote.

Does O2 Business offer 4G back-up?

Yes. It sells 4G mobile broadband at up to 150 Mbps with 10GB or unlimited data, as a temporary connection or a back-up.

How do I cancel O2 Business broadband?

Give written notice. If your business has 10 or fewer workers, 30 days' notice is enough, effective no earlier than the end of your minimum term. Larger businesses need to give 90 days' notice before the minimum term or rollover period ends, or the contract renews for another 12 months.

What compensation do I get if my O2 Business broadband goes down?

None under the general terms, which promise reasonable endeavours and exclude liability for interruptions. Any compensation would need to be in your order form or a service-specific agreement, so ask before you sign.

Is O2 Business broadband reliable?

O2 Business claims 99% to 99.9% reliability on different pages but doesn't say how it measures this. There's no Ofcom complaints data for the company, and its contract doesn't include a published fix time.

What network does O2 Business broadband use?

It depends on your address. Daisy says it buys broadband from major suppliers including BT, TalkTalk and Virgin, while O2 Business's 4G product uses the O2 mobile network.

Is O2 Business broadband available at my address?

Almost certainly in some form, because it sells SoADSL and 4G broadband for hard-to-reach premises. Check what's available on our business broadband availability checker before you compare quotes.

Our Verdict: Is O2 Business Broadband a Good Choice?

O2 Business broadband is a reasonable choice if you want one supplier for connectivity, phones and mobiles, and you value a support team that customers rate highly. For a business with 10 or fewer workers, a fixed pounds-and-pence rise and an included static IP make it competitive with the bigger names, provided the quote is right.

Where it's less convincing is transparency. There's no published price, no published fault-fix target, and the general terms leave you with little remedy if your connection fails. Larger businesses also face inflation-linked rises and an automatic 12-month rollover. In our experience reviewing business broadband contracts, those are the terms that cost owners money, not the headline speed.

Before you sign, get three things in writing: the monthly price and the exact April rise, the minimum guaranteed speed, and the fault-fix target with any compensation. Then compare that quote against at least one provider that publishes its prices.
