Onestream Broadband

OneStream based in Hampshire was founded in 2018 with the view to challenge the “big 4” (Virgin Media, BT, Sky & TalkTalk). Using BT’s Openreach network, Openstream offer 3 different fibre broadband deal, but are they any good?


Download Speeds17, 45, 67 Mbps
Upload Speeds1.5, 7.5, 17.5 Mbps
Type of broadbandFibre (FTTC)
Home Phone/TV PackagesYes/No
CostFrom £26.99/month.


One stream has three different speeds available, all of them using a fibre connection (FTTC) which runs on the Openreach network. 

Onestream’s introductory broadband package using fibre is called “Onestream Fibre 20”, and promises and average download speed of 17 Mbps, and a top download speed of 20 Mbps. This is an unusual speed offered on the Openreach network with most providers offering the quicker 35Mbps as their introduction into Fibre. However, this speed option could be useful for a couple who need to video call or stream at the same time, or an elderly person with lower internet requirements. Although starting at £26.99 households with low usage should be able to find cheaper deals on the market. The average upload speed for this deal is 1.5 Mbps, which would potentially struggle transmitting a clear video signal when using Zoom. 

Their next deal is called “Onestream Fibre 55”. As the name reveals, the top download speed of this deal is 55 Mbps, and the average download speed is at 45 Mbps. Average upload speeds are at 7.5 Mbps, sufficient for comfortably using Zoom or uploading files to the internet.

This broadband deal would be a good choice for a small family or a couple with many connected devices. 

Finally, Onestream’s fastest deal is named “Onestream Fibre 80”, with a top download speed of 80 Mbps, and an average speed of 67 Mbps, and an average upload of 17.5 Mbps. This deal is recommended for households, where multiple people want to use streaming services as Netflix or game at the same time. 


Onestream’s broadband offers a “super dooper router” (their words not ours) TP-Link 300 Mbps Wireless Router with all their broadband packages. This should be fast enough for most users and is sourced to complement their broadband offerings and currently gets a 4/5 on Amazon from 220+ reviews. With it being an entry level router though, it may experience a common issue of not working too well once more than 10 devices are connected to it. 


Onestream hasn’t committed online to how long their installation procedure takes, but if you have an existing landline on the Openreach network switching is likely to take will take an industry standard of around 10-14 days to switch you over to them. In this time, they’ll send you your new router (£9.99 P&P) and then it will be a relatively simple process of plugging in and getting online on the allotted date. 

If you don’t have a landline or you are currently on Virgin’s network, you will need to arrange an installation with them. An installation fee will be charged (up to £60.00) which is also standard for all Onestream’s competitors on the Openreach network. 


As of December 2021, Onestream has an “excellent” rating of 4.7 out of 5 on Trustpilot. 

Onestream have an FAQ page on their site to help their customers find quick answers to common questions. They also have a customer support team, which is all based in the UK, and can be contacted via phone, email or their live chat function on their website.

You can call them on 0333 241 4449, 08:30 to 17:00 during the week, whereas the live chat is available during the following times: Mon- Fri 08:30 – 20:00 Sat 10:00 -16:00  


What we likeWhat we are not too keen on
Good selection of speeds on offerMore expensive than competition
Great Trustpilot scoreNo TV bundles
 Glitchy website

While Onestream uniquely offers fibre broadband for low usage, the price tag of their deals across the board, do not reflect the speeds on offer. Other providers on the Openreach network have cheaper deals available at a lower cost. However, Onestream broadband triumphs with their high customer satisfaction, which could make them a viable option, provided that your area has access to fibre connections.
