Sky's Full Fibre Gigafast package is its fastest widely available package, giving you stonking-fast download speeds averaging 900Mbps. That’s the kind of speed that makes buffering, lag, or slowdown of any kind a thing of the past, even in homes with dozens of connected devices. Sky also includes a 600Mbps speed guarantee – if your line falls below that, you can claim £5 back, refunded directly to your bill.
At £38 per month on a 24-month contract, Sky Gigafast is a very competitive Full Fibre option, particularly given it comes with zero upfront costs and pay-as-you-go calls bundled in as standard. And right now, if you order online as a new customer you’ll also get a £100 gift card, which helps take the edge off the first year’s costs. Combine that with the fact that Sky's customer service record is riding very high right now, and the ability to leave penalty-free if Sky raises prices mid-contract, and this is a package that delivers a lot of peace of mind.
Effective monthly cost is calculated by adding up all the monthly costs, price rises and any discounts and dividing it by the contract length.
You will be sent instructions on how to choose your Gift Card up to 120 days after your purchase. You will have 90 days to claim your Gift Card by sending it to your email or mobile phone.
The sweetener on Sky Gigafast is a £100 gift card Gift Card, and unlike some offers, it isn’t applied automatically – you’ll need to follow a couple of steps to get it. Once your Sky broadband service is live, your order is validated (which can take up to 120 days). After that, you’ll receive an email from Giftcloud with instructions on how to choose your voucher.
You’ll then have 90 days to claim it, and you can pick from a range of retailers such as Tesco, Amazon, M&S, Sainsbury’s, John Lewis, and Currys. The voucher is sent digitally to the email address you signed up with.
It’s important to note that if you cancel your order, claim late, or buy through another channel such as phone or webchat, you won’t be eligible. The gift card cannot be exchanged for cash, and only one voucher is issued per customer.

Sky Full Fibre Gigafast comes in at £38 per month on a 24-month contract, with zero upfront costs. For that price, you’re getting an average speed of 900Mbps. It' not the fastest speed available among Openreach providers – EE Broadband's gamer-focused 1.6Gbps package wears that crown – but it is arguably far more than most homes need regardless. Sky also includes a 600Mbps speed guarantee: if your line ever drops below that threshold, you’ll automatically get £5 credited back to your bill.
What makes Gigafast stand out though isn’t just the raw speed – it's the headroom it gives you when you've got a lot of devices in your home. 900Mbps is frankly overkill for most households today – but it also means you can run multiple 4K streams, download huge videogames in minutes, back up entire photo libraries to the cloud, and keep dozens of smart devices connected without compromise. If you’re running a busy household, working from home, or just don’t ever want to think about your broadband being the bottleneck, Gigafast is the fire and forget option.
On top of the performance, you'll also get a £100 gift card. Add in Sky’s strong reliability record, nationwide availability, and the rare promise that you can leave penalty-free if Sky hikes your price mid-contract, and you’ve got one of the most complete, fast and reliable broadband packages available today.
Effective monthly cost is calculated by adding up all the monthly costs, price rises and any discounts and dividing it by the contract length.
You will be sent instructions on how to choose your Gift Card up to 120 days after your purchase. You will have 90 days to claim your Gift Card by sending it to your email or mobile phone.
With average speeds of 900Mbps, Sky’s Gigafast package is extremely quick. Not just fast enough for the usual streaming, gaming, and working from home – it’s the kind of headroom that means you never need to think about who’s online or what they’re doing. You could have multiple 4K streams running, cloud backups ticking away in the background, huge game downloads in progress, and still have plenty left over for everything else in your household.
To put it in perspective, a 50GB console game that might take an hour or more on a slower package can download in under ten minutes here. Uploads are solid too, so sending large video files, backing up photos, or hosting smooth video calls is straightforward. And with Sky’s 600Mbps speed guarantee in place, you’ve got peace of mind that your line won’t suddenly drop to disappointing speeds – if it does, you’ll see money back on your bill.
For most households, Sky Gigafast is overkill – but that’s the point. It’s built to stay ahead of the curve, giving you a future-proof connection that can handle whatever the next few years throw at it. If you’d rather never worry about your broadband speed again, this is the tier that takes that off the table for the foreseeable future.

Sky includes its standard Sky Broadband Hub with the Gigafast package. That’s the default – solid, reliable, dual-band, and suitable for most folk. However, if you’re looking for something with a bit more oomph, you can opt for the Sky Max Hub instead by adding the 'WiFi Max' upgrade to your package (which is currently just £3 extra per month and comes with additional benefits). In the case of a 900Mbps package we would honestly say the Wi-Fi Max upgrade is non-negotiable. You're going to need Wi-Fi 6 to have a chance of using all that speed. Let's take a quick look at their specs:
Feature | Sky Broadband Hub | Sky Max Hub |
---|---|---|
Wi-Fi standard | Wi-Fi 5 (802.11ac) | Wi-Fi 6 (802.11ax) |
Bands | 2.4 GHz & 5 GHz | 2.4 GHz & 5 GHz (better switching/faster) |
Ethernet ports | 4 x 1 Gbps LAN | 4 x 1 Gbps LAN (speedier internal performance) |
Extras | Smart channel selection, Smart Scan, dual-band | All above plus better QoS, device prioritisation, optional WiFi Max Pods (range extenders) |
The standard Sky Broadband Hub is perfectly capable of delivering 900Mbps wirelessly around a typical home, but it's going to struggle to send more than a couple of hundred megabits per second to any single device wirelessly. The Sky Max Hub (vai the upgrade) is going to be a better option. Especially in larger homes, or if you need more advanced controls like device prioritisation or to extend your homes Wi-Fi coverage via the Sky WiFi Max Pods.
Sky runs on the Openreach network, so installation depends on what’s already in your home. If you currently have Standard Fibre, an engineer will usually need to upgrade you to a Full Fibre line, which may involve running a new cable into the property. If you’ve already had Full Fibre installed before, Sky can often just post you the Hub for a simple self-setup deal.
Switching is easy thanks to Ofcom’s 'One Touch Switching' rules – once you sign up with Sky, it’ll manage the handover with your old provider. For renters, it’s worth checking with your landlord if any new cabling or drilling is required because you'll need permission, but for most households the process is quick and painless.
One of the nice touches with this Sky deal is that there are no setup or activation fees. Some providers still charge up to £35 for installation or router delivery, but here it’s all included in the monthly price.
That means what you see is what you pay – just the monthly cost of the package, with no hidden extras creeping into your first bill.
Sky has built a strong reputation as one of the UK’s most reliable broadband providers, offering a wide choice of packages, solid speeds, and customer service that regularly scores top in Ofcom’s reports – often having the fewest complaints of any major provider. With Full Fibre now widely available through Openreach, Sky can deliver much faster and more consistent speeds than Standard Fibre ever could.
This Gigafast deal is the nuclear, fire and forget option – fast enough for everything and then some, from gaming and streaming, to working from home. Add in decent routers, optional WiFi Max upgrades, and competitive pricing, and Sky makes a very solid case for itself here.
