Sky Business Broadband Review: Honest Verdict for 2026

What is Sky Business broadband?

Sky entered small-business broadband in March 2021 under the Sky Connect brand — you'll still see both names — selling business-grade broadband over the Openreach network, initially FTTC and now led by full fibre (FTTP). It is aimed squarely at small and micro businesses: shops, offices, hospitality sites. Larger multi-site or SLA-driven requirements sit outside what the product is built for, which Sky itself implicitly acknowledges by not publishing fix-time commitments.

Packages after the March 2025 restructure

From 4 March 2025 Sky reorganised its business line-up into Essential, Advanced and Ultimate broadband-only tiers (plus an Ultimate Plus tier on the broadband-and-voice side), each available at five download speeds: roughly 75, 150, 300, 500 and 900Mbps, with uploads from about 19 to 85Mbps. Confusingly, older Sky pages and many comparison sites still describe the previous Essential/Pro/Plus naming with a "Speed Flex" add-on — if you're quoted against the old names, you're reading stale information. The tier you pick mostly decides the service wrap: the headline one being that automatic 4G backup ("Connection Pro") comes with the mid and upper tiers, not with Essential.

The 4G backup guarantee — genuinely good

Sky's most distinctive feature is its backup promise: if the 4G backup doesn't kick in within 30 seconds of a reported outage, Sky credits you £25 (report within 24 hours). We're a competitor and we'll say it plainly: a money-backed continuity commitment at small-business prices is a good thing, and more providers should do it. The caveats are that it's a credit rather than a fix-time SLA — your connection is degraded to 4G speeds while the fault lasts — and that the Essential tier doesn't include backup at all, which for a card-machine-dependent business is the wrong tier to save money on.

Pricing and the small print

Published entry pricing is advertised from around £21.50–£27.95 ex VAT a month depending on where you read (comparison sources conflict, and Sky's own pages have moved with the restructure — treat any figure, including these, as needing a live check). Contracts run 24 or 36 months. Static IP — which most businesses should take — is a modest add-on at £4.95 ex VAT a month. Installation on full fibre is currently offered at £0 against a stated standard £99. The line worth reading twice: Sky states prices won't rise during 2026, but reserves the right to raise them from 1 January 2027 — including mid-contract. On a 36-month term signed today, that's most of your contract exposed to a rise you can't exit for.

Where Sky fits against the market

On complaints, the Sky brand performs well: Ofcom's Q1 2026 data (published July 2026) records Sky at 5 complaints per 100,000 broadband customers against an industry average of 6 — among the best of the big brands. Honest caveat: Ofcom's league table measures residential service, and no business-specific complaints dataset exists, so treat it as a brand signal rather than a business-service guarantee. Structurally, Sky is Openreach-only: no CityFibre or altnet routes, so if a rival network reaches your street with a sharper price, Sky can't quote it — and a carrier-independent comparison will.

Our verdict: who should buy it

Sky Business broadband is a credible choice for a small, single-site business on the Openreach footprint that wants a recognised brand, digital voice in a bundle, and the 4G backup guarantee — take the Advanced tier or above so the backup is actually included, add the static IP, and go in with eyes open on the 2027 price-rise clause. Where it stops being the answer: multi-site estates, anything needing a fix-time SLA, upload-heavy work (uploads top out around 85Mbps), or postcodes where CityFibre or Virgin routes undercut Openreach pricing. That last part is exactly what we check: AMVIA compares every network reaching your address — business broadband from £29/month, SoGEA where fibre hasn't arrived, and leased lines from £69/month when the SLA matters — and if Sky genuinely wins at your postcode, we'll tell you that too.
