Cheapest Business Broadband: Price Index 2026-27

Our calculations are based on the provider prices listed in the dataset above. Vodafone's rise rule (+£2.93 on 1 April each year in the minimum term) is from the Vodafone Business broadband page. Sky's price lock wording is from the Sky Business Essential package page.

Our Analysis: Where the Headline Price is Misleading

• Virgin Media Business has the biggest gap. Voom 200 is advertised at £29.95, but £100 in upfront charges and two £3.50 rises push the real cost to £38.20 a month. That's 27.5% more.

• Vodafone's three-year term works both ways. It's still the cheapest package overall, but three April rises take the final months to £30.79 a month. If you sign in December, the first rise lands just four months in. Models that assume three neat 12-month price bands put the total at about £897. For a December start, the real figure is £967.80.

• Fixed-price providers are the easiest to budget for. Zen and IDNet both come within about 7% of their headline price, because the only extra is a one-off setup fee.

• Short contracts cost more per month but less in total. bOnline's 12-month term means the lowest total commitment in the index (£441). Its setup fee is spread over fewer months, though, which pushes the effective price up.

How Much Do Static IPs Add to Business Broadband Costs?

A static IP is a fixed internet address. You need one if you run a VPN, access CCTV remotely, host a server or use software that only accepts connections from approved addresses. Many small businesses don't need one.

Cheapest Business Broadband Providers: Quick Verdicts

Vodafone Business

The cheapest business broadband in the UK right now. You get 900Mbps and a static IP for £22 a month, but it comes with a 36-month contract and three annual rises. Best for businesses happy to commit for three years.

Sky Business

The best-value entry and mid-range packages with no setup fee. The catch is that Sky hasn't said how much prices could rise from January 2027, and these are Black Friday prices. Best for businesses that want low upfront costs.

IDNet

The most predictable low price. No rises, a static IP included and symmetric upload speeds on CityFibre. Its Openreach packages cost £14 to £23 a month more, so check which network serves your premises. Best for businesses that need to upload large files or want a fixed budget.

Virgin Media Business

Competitive headline prices, but the most expensive of the national providers once fees and rises are added. Voom 600 and Gig1 include a static IP, which helps. Best for businesses already on Virgin's network that want its symmetric Full Fibre X option.

Zen Internet

You pay more per month but get no in-contract price rises, a static IP and an 18-month term. Its gigabit package is £11.65 more a month than Sky's. Best for businesses that value support and price certainty.

TalkTalk Business

Decent entry pricing with a free static IP, but its gigabit package ranks last for value. It doesn't list a mid-range tier on its plans page. Best for businesses on the Openreach network that only need 150Mbps.

bOnline

The shortest contract in the index. It costs more per month, but your total commitment is the lowest. Best for start-ups and businesses that may move premises within a year.

XLN

Low, stable headline prices, but the size of the annual rise isn't published until you sign, and XLN says it applies to the pre-promotion price. It doesn't list a gigabit package online. Best for small businesses that want XLN's bundled card payment and phone services.

Gigaclear Business

Expensive, but often the only full fibre option in rural areas. Its prices jump by up to 71% once the 24-month term ends. Best for rural businesses with no alternative.

BT Business

BT's Essential plans start from £22.46 a month on a 36-month contract (25% off selected speeds until 15 November 2026), rising by £3 every April. BT doesn't publish per-speed prices without an address check, so we couldn't rank it. Its own pages also show a £39.95 connection fee waived on the offer and a £5.95 hub delivery charge. If you need a static IP, the Enhanced tier (from £27.97) includes one free and can work out cheaper than Essential plus the £8.96 add-on. For a deeper look, read our BT business broadband review.

Hyperoptic Business

Hyperoptic sells 250Mbps, 500Mbps and 1Gb symmetric packages with a static IP on rolling, 12, 24 and 36-month terms. It doesn't publish business prices online, so you'll need a quote.

KCOM

KCOM runs its own full fibre network in Hull and East Yorkshire, with symmetric 150Mbps and 500Mbps packages, a 900Mbps package and a static IP included on every plan. Its last published business offer ended on 2 November 2026, and prices now need a postcode check. Only relevant if you're in its area.

O2 Business (formerly Daisy)

Daisy's online shop used to list business full fibre from £29.95 a month. Since the April 2026 rebrand to O2 Business, those pages redirect to a mobile-only shop, so broadband is now quote-only. If you want Virgin Media O2's business broadband online, Virgin Media Business is the brand that still publishes prices.

Why is Gigabit Business Broadband Cheap?

Gigabit is cheap because the networks that deliver it are now everywhere and competing for customers. Ofcom's Spring 2026 Connected Nations update found full fibre was available to 24.9 million UK homes (82%) by January 2026, and gigabit-capable broadband to 89%. The same report found only 47% of premises with full fibre access had taken it up.

That gap between availability and take-up gives providers a reason to compete hard on price. In our data, the step from 150Mbps to 900Mbps at the same provider is often under £10 a month, so top-tier speed has become the main way to win customers.

If you're still on a part-fibre (FTTC) line because you assume full fibre costs more, this index suggests it usually doesn't.

Can Business Broadband Prices Rise Mid-Contract?

Yes, at most providers. Since 17 January 2025, Ofcom's rules have banned inflation-linked and percentage-based rises in new contracts. Any rise must be set out in pounds and pence when you sign.

If a provider doesn't do that, it has to give you a month's notice of a rise and let you leave without a penalty. Osborne Clarke's summary of the rules confirms they cover small businesses as well as consumers.

How to Get the Cheapest Business Broadband

1. Check what full fibre networks reach your premises. Your options depend on whether you're on Openreach, CityFibre, Virgin Media or a regional network. IDNet's CityFibre and Openreach prices differ by up to £23 a month for the same speed.

2. Compare effective monthly cost, not headline price. Add the setup fee and every published rise, then divide by the number of months.

3. Price the gigabit tier before you settle on entry level. In this index, the upgrade often costs less than £10 a month.

4. Decide whether you need a static IP. If you do, choose a provider that includes one.

5. Match the contract length to your plans. If you might move within two years, a 12 or 18-month term can save you an early exit fee.

6. Diary your end date. Gigaclear's prices rise by up to 71% once the minimum term ends, and bOnline's by up to 12.5%.

FAQs About Cheap Business Broadband

What is the cheapest business broadband in the UK?

Vodafone Business Full Fibre 900, at £22 a month ex VAT on a 36-month contract. Including its annual rises, it works out at £26.88 a month, which is still the lowest in our index.

How much should a UK small business pay for broadband?

Between £27 and £35 a month ex VAT for full fibre, based on the cheapest effective costs in our index. Paying more than £45 a month for a standard full fibre line usually means you're overpaying.

Is business broadband more expensive than home broadband?

Usually a little. Sky's home Full Fibre 900 was £28 a month including VAT in October 2026, while Sky Business Essential 900 costs £34.35 ex VAT. Business plans add support, static IP options and minimum speed guarantees, and VAT-registered businesses can reclaim the VAT.

Is cheap business broadband reliable?

Yes. Price doesn't decide reliability; the network does. Vodafone, Sky and BT all sell over Openreach full fibre, so the line itself is the same. What changes is support, fix times and extras like 4G backup.

Do I need a static IP address?

Only if you run a VPN, host a server, access CCTV remotely or use systems that whitelist IP addresses. If you don't, choose the package without one and save up to £8.96 a month.

Is 900Mbps broadband worth it for a small business?

Yes, if full fibre reaches you. The gigabit tier often costs less than £10 a month more than entry level, and it gives you room for cloud backups, video calls and more staff.

Can I claim business broadband as an expense?

Yes. Business broadband is an allowable business expense, and VAT-registered businesses can reclaim the VAT on it.

What happens when my business broadband contract ends?

You usually move to the provider's standard price, which is often higher. Gigaclear's 100Mbps package jumps from £50 to £85.50 a month. Check your end date and renegotiate or switch before it arrives.

Which business broadband has no price rises?

Zen Internet and IDNet. Both fix the price for the full contract. bOnline and Gigaclear also hold their price for the minimum term.

Summary: The Cheapest for 2026-27

The cheapest business broadband isn't the slowest. In our 2026-27 index, gigabit packages cost less than a quarter as much per Mbps as entry-level ones, and Vodafone's 900Mbps line was the cheapest package overall at £22 a month (£26.88 effective).

If you want low costs and price certainty, IDNet and Zen are the safest bets. If you want the lowest upfront cost, Sky Business has no setup fee, but watch for rises from January 2027. Whichever you choose, compare the total contract cost, not just the headline price.
