Gigabit broadband deals UK August 2026: first-year cash, not the 1Gb tile

Last updated: Monday 31 August 2026 (Europe/London).
Next update: when YouFibre’s 1–31 August promo ends (tonight), when Community Fibre’s 10% sale ends on 16 September 2026, or when Virgin, EE, BT or TalkTalk change the disclosed March/April 2027 rise on their own shops. Until then, treat every monthly figure as a 31 August snapshot and re-check the contract summary at your postcode.

I am Switch. I compare broadband deals for a living, and gigabit broadband deals UK August 2026 is not the same search as cheapest broadband or the 500 Mbps family tier.

Cheapest can be a 35 Mbps London sale, a 5G hub, or a copper last mile. Five hundred megabits is enough for most 4K households. Gigabit is the next shop: many simultaneous 4K streams, big uploads, NAS backups, or future-proofing when the street already has full fibre or Virgin’s top cable tier. Ofcom’s Connected Nations Spring 2026 update — cited today via Compare the Market — puts roughly 89% of UK homes as gigabit-capable and about 82% on full fibre. Plenty of those homes can now buy a named 900 Mbps or 1 Gbps package. The job is ranking what that year actually costs.

uSwitch’s only dedicated gigabit URL is an explainer — What is gigabit internet? — last updated 22 April 2026, still quoting January 2025 coverage (86%). Gigabit deals sit buried on the generic fibre compare page (“updated 28 August 2026”), which still features Vodafone Full Fibre 150, not a first-year gigabit ranking. MoneySavingExpert has no dedicated gigabit deals URL. Our own broadband hub still leads on BT YouView TV bundles — not FTTP gigabit cards. That is television. It is not a 900 Mbps shopping list.

This page ranks gigabit broadband deals UK August 2026 by first-year cash from retailer own sites only: intro monthly, the March or April 2027 rise already written into the contract, setup. Not commission. Not a Sport pack. Not a comparison exclusive that is cheaper than the ISP shop. If you only want the absolute lowest bill at any speed, use cheapest broadband UK August 2026. If you want glass to the door without a speed filter, use cheapest full fibre broadband UK. If 500 Mbps is already enough, stay on 500Mbps broadband deals UK August 2026 — do not upsell yourself into a gigabit bill you will not use.

Compare broadband deals at your postcode. Filter for ~900 Mbps or 1 Gbps. Ignore the first monthly number until you have the rise, the setup, and the technology in writing.

How I count a year

Contract start roughly Monday 31 August 2026. First twelve months of cash.

For a deal that discloses a rise on 31 March 2027 (BT Group: BT, EE) or April 2027 (Virgin, TalkTalk):

• seven months at the intro rate (September 2026 through March 2027)

• five months at the risen rate (April through August 2027)

Add setup or activation. Do not subtract a gift card or switching credit unless I could confirm it is still live today and I can put a claim process on it. Reward cards are noted in sources where they matter; they are not netted from the totals I am underwriting.

YouFibre’s 24-month August promo and Community Fibre’s in-contract lock have no mid-term April rise in year one, so those rows are simply twelve times the locked monthly plus setup.

I rank the cost of staying twelve months. Leaving-fee credits only count after you send the old bill. None of those is a promise it covers your specific exit fee.

I rank by that first-year cash, not by who pays Switch the most.

What gigabit is for

Ofcom treats gigabit-capable as around 1 Gbps. The mass-market shop sells “Full Fibre 900”, Sky Gigafast, Vodafone 910 and Virgin Gig1 in the same aisle. One 4K stream needs about 25 Mbps. Two or three 4K streams, a video call, cloud backups, and a console download at once are why people leave 67 Mbps FTTC — and why many stop happily at 500 Mbps.

Gigabit is for denser households: several 4K streams plus large uploads, a home NAS, creative work uploading raw footage, or future-proofing when the street already has FTTP or Virgin’s top cable tier. You do not need it for one laptop and Netflix. You need a real average near 900–1100 Mbps on a wired test, a minimum guarantee where the Openreach products print one, and a router that is not a Home Hub 4 in a YouView photo.

Virgin Gig1 advertises about 1136 Mbps download on its own site. EE and BT Full Fibre 900 print 900 Mbps average with a 700 Mbps guarantee. YouFibre YOU 1000 quotes about 900 Mbps down/up on a wired test. Community Fibre’s 1 Gbps card is symmetrical 1000/1000 where they have built. Those are different products: cable, Openreach FTTP, altnet FTTP. Do not buy the badge. Buy the technology at your address.

Gigabit deals I could verify this morning

Prices below are Monday 31 August 2026. New customers. Broadband-only unless I say otherwise. All figures come from the retailer’s own shop (or that ISP’s live comparison table on its own domain). None of them is available at every UK address. I have not invented a cheaper unnamed 900 Mbps tier, and I have not used uSwitch’s Virgin Gig1 tile at £23.99 — Virgin’s own shop is £29.99.

Rank twelve months of cash. Community Fibre’s £22.50 London sale is £270. YouFibre’s £25 lock is £300. Virgin Gig1 on virginmedia.com is £379.88 once April is in the sum — still the national lead ahead of EE and BT 900. EE’s own-site £31.99 is £413.88 with setup and March. BT’s matching monthly with a heavier setup lands at £433.88.

Worked first-year sums, so you can see I have not rounded the story:

• Community Fibre 1 Gbps: 12 × £22.50 = £270. Price locked in-contract; £0 setup. The 10% flash sale on communityfibre.co.uk/deals runs to 16 September 2026. Rise of +£4 is only after the term, then +£3 each April — not in year one.

• YouFibre YOU 1000: 12 × £25 = £300. Fixed for 24 months on the 1–31 August 2026 promo; £0 standard install. Re-fetch offer T&Cs if you publish after tonight.

• Virgin Gig1: 7 × £29.99 = £209.93, 5 × £33.99 = £169.95. Total £379.88. No setup on QuickStart. Virgin’s help page: +£4 each April for joins after 2 October 2025.

• EE 900Mbps Core: 7 × £31.99 = £223.93, 5 × £35.99 = £179.95, plus £10 setup = £413.88. Month 1 prints as £41.99 including the fee.

• BT Full Fibre 900: month 1 £61.99 (includes £30 setup) + 6 × £31.99 = £191.94 + 5 × £35.99 = £179.95. Total £433.88.

• TalkTalk Full Fibre 900: 7 × £36 = £252, 5 × £40 = £200. Total £452. £0 setup.

• EE 1.6Gbps Core: 7 × £40.99 = £286.93, 5 × £44.99 = £224.95, plus £30 setup = £541.88.

• Virgin Gig2: 7 × £49.99 = £349.93, 5 × £53.99 = £269.95. Total £619.88. £0 setup. Selected full-fibre postcodes only.

Lead where Community Fibre or YouFibre exist: those two win on cash and have no in-contract April rise in year one. Lead for most of the UK: Virgin Gig1 at £379.88 first year, £0 setup, about 1.1 Gb advertised — still cheaper than EE/BT 900 once setup and the March rise are counted.

London altnet versus national coverage

Community Fibre only exists where they have built — mainly London. YouFibre (Netomnia) is postcode-specific too. If the checker returns nothing at 1 Gbps, they have not built your street. Then the honest options are Virgin Gig1 where the cabinet is yours, Openreach Full Fibre 900 from EE or BT, TalkTalk Full Fibre 900 on TalkTalk’s own shop, or waiting — not paying for YouView Sport because it loaded first on our hub.

EE and BT on Openreach give you the widest footprint for a named 900 Mbps full fibre product. Their own sites today both print £31.99 intro; the difference is setup (£10 versus £30) and how the first-year sum lands after 31 March 2027. Open ee.co.uk or bt.com before you celebrate a comparison tile that has already moved.

Virgin Gig1 is the national broadband-only lead I could verify on an own shop this morning. Gig2 is a different product: selected full-fibre areas, 2000 Mbps down, and a first-year cash of £619.88. Do not confuse the two when the postcode checker offers both.

One more TalkTalk note that is not a ranked gigabit row: TalkTalk U at £25 (rising to £29 in April 2027, £0 setup, about £320 in year one on the same 7+5 math) is an adaptive 65–900 Mbps product at one price. It is not a guaranteed gigabit SKU. If the line actually lifts toward 900 at your address, it can be the cheapest TalkTalk path — but I will not put it in the gigabit table as if it were Full Fibre 900.

Why 900 Mbps counts as gigabit here

Openreach and CityFibre “Full Fibre 900”, Sky Gigafast and Vodafone 910 are the mass-market gigabit-capable tier. Ofcom’s gigabit-capable definition sits around 1 Gbps; the industry ranks 900 Mbps+ in the same shop aisle. Virgin Gig1 is the one that actually advertises 1136 Mbps. EE and BT print a 700 Mbps speed guarantee under the 900 average. I have ranked every retailer-verified 900 Mbps+ broadband-only deal I could open today. I have not mixed in 500 Mbps rows — those already have their own page.

What I dropped because I could not verify a clean broadband-only 900+ floor on the retailer’s own shop today: Sky Gigafast broadband-only (Sky’s landing page is postcode-gated; TV+900 bundles are not this table), Vodafone Full Fibre 910 (homepage only prints “from £24” across 74–910 Mbps), Plusnet Full Fibre 900 (hero is a “from £24.99” Full Fibre floor, not an isolated 900), Hyperoptic 1Gb (JS-gated; setup not cleanly listed), NOW Broadband (tops out at Full Fibre 300), and uSwitch’s Virgin Gig1 £23.99 tile (cheaper than Virgin’s own £29.99 — SwitchSquid ranks retailer shops only).

Wi-Fi versus wired honesty

You will rarely see a full gigabit on a phone. YouFibre, Community Fibre and similar altnets quote wired or ethernet averages. Wi-Fi 6/7 and wall losses cap real-world laptops and phones well below 1 Gbps. Ethernet to a desktop, NAS or console is the honest test. If the contract promises 900 Mbps and your living-room tablet shows 180, that is usually the air, not the fibre.

Buy the line speed for the rooms you care about, then mesh or wire the last metres. Do not pay Gig2 cash for a single phone browsing Instagram on the far side of a Victorian terrace.

Live cards above pull from the same feed as the hub. They may return junk or TV bundles. Treat them as a starting point. The ranking table is the retailer-verified first-year cash.

FAQ

Do I actually need gigabit, or is 500 Mbps enough?

Most 4K, work-from-home and gaming homes are fine on 300–500 Mbps. Gigabit is for many simultaneous 4K streams, big uploads, a busy NAS, or future-proofing when the street already has the network. If you are not sure, start with 500Mbps broadband deals UK August 2026 and only step up when the postcode checker shows a gigabit row that still makes sense on first-year cash.

Why do providers sell “gigabit” at 900 Mbps?

Openreach and CityFibre “Full Fibre 900”, Sky Gigafast and Vodafone 910 are the mass-market gigabit-capable tier. Ofcom treats around 1 Gbps as gigabit-capable; the industry ranks 900 Mbps+ in the same shop. Virgin Gig1 is the one that actually advertises about 1136 Mbps. EE and BT print a 700 Mbps guarantee under the 900 average.

Will I get gigabit on Wi-Fi?

Usually no. Altnets quote wired averages. Wi-Fi 6/7 and walls cap phones and laptops well below 1 Gbps. Ethernet to a desktop or console is the honest test. Mesh the house after you buy the line, not instead of reading the average speed.

Which gigabit deals do not rise in April 2027?

YouFibre’s 24-month August promo is fixed for the term (promo ends tonight, 31 August 2026). Community Fibre locks the in-contract price; the +£4 rise is after the term. Virgin, EE, BT and TalkTalk all disclose a March or April 2027 rise — that is why Virgin’s £29.99 tile is £379.88 in year one, not £359.88.

Can I get gigabit at my postcode, and how do I switch?

Ofcom Spring 2026 (via Compare the Market, fetched 31 August 2026): about 89% of UK homes are gigabit-capable and about 82% have full fibre. Availability is still address-specific — Virgin Gig2 and the London altnets especially. Use One Touch Switch where it applies. Compare broadband deals at your postcode, then read the technology and the first-year cash before you click through.

Compare at your postcode

The gigabit deal only exists if the network has built the street or Virgin’s cabinet is actually yours. Check your postcode on the broadband hub.

Then, before you click through:

• Technology: FTTP, cable, or something else. “Fibre” on the badge is not enough.

• Average and minimum guaranteed speed. EE and BT 900 print a 700 Mbps guarantee.

• The mid-contract rise, in pounds, with a date — or a genuine lock.

• Setup or activation.

• What happens when the minimum term ends. Virgin Gig1 goes to £86 from month 25 on today’s legal copy. YouFibre’s list after the promo term is currently £39.99.

I rank by total first-year cost. If the cheapest gigabit row at your address is a London altnet you have not heard of, that can still be the right bill. If nothing near 900 Mbps appears, they have not built yet — and our hub’s YouView lead is still not the answer.
